Minimum 4 seconds`, decrease the `blockperiodseconds` from 4 seconds to 3 seconds to match the imported chain. + +After you update the new genesis file, if the imported chain has a `blockperiodseconds` value set lower than you prefer, you can adjust it by [configuring the block time on an existing QBFT network](#configure-block-time-on-an-existing-network). + +::: + +The properties with specific values in the QBFT genesis files are: + +- `difficulty` - `0x1` +- `mixHash` - `0x63746963616c2062797a616e74696e65206661756c7420746f6c6572616e6365` for Istanbul block identification + +To start a node on a QBFT private network, use the [`--genesis-file`](../../../../public-networks/reference/cli/options.md#genesis-file) option to specify the custom genesis file. + +### Extra data + +The `extraData` property is an RLP encoding of: + +- 32 bytes of vanity data. +- If using: + - [Block header validator selection](#add-and-remove-validators-using-block-headers), a list of validator addresses. + - [Contract validator selection](#add-and-remove-validators-using-a-smart-contract), no validators. +- Any validator votes.

If transaction throughput or latency is not meeting your expectations, please consider the following before raising an issue. + +## General performance + +Private transactions use the same facilities as public ones. General Besu performance tunings apply. Specific approaches are out of scope of this document, except for the following, which strongly impacts performance: + +### Use fast, local, solid state storage + +Running EVM transactions creates a lot of random reads that are executed sequentially. The Besu data folder for high throughput nodes should be located on the fastest possible storage media. + +- Prefer [NVMe](https://cloud.google.com/compute/docs/disks/local-ssd#performance) attached SLC flash or Intel Optane. +- Avoid network attached SSDs or cloud storage with limited input/output operations per second. +- Do not use spinning disks under any circumstances. + +## Private transaction performance + +### Use concurrent submission + +When submitting a private transaction using [web3js-quorum](https://github.com/ConsenSys/web3js-quorum), the submit call will only return once the privacy marker transaction has been included in a block. This limits the throughput to at most one private transaction per block when submitting from a single thread. To increase throughput, use web3js-quorum from multiple concurrent threads or processes. + +### Co-locate Besu and Tessera + +Besu has to talk to its local Tessera node frequently while handling a block. While we do not recommend running them on the same node, minimizing the latency between Besu and Tessera will improve block processing times. Besu and Tessera should not be hosted in geographically distributed locations. + +### Optimize worst-case latency between Tessera nodes + +When distributing a new private transaction between Tessera nodes, the overall throughput is determined by the slowest Tessera nodes. Try to minimize network latency between Tessera nodes and do not mix different machine types when hosting Tessera. + +### Use stateful nonce management + +Management of public and private nonces in web3js-quorum is stateless: before a transaction is sent, web3js-quorum has to query for those nonces. This is increasing latency, the node's load, and is a source of fragility due to nonce collision when multiple senders try to use the same account concurrently. + +For performance and reliability it is advantageous to manage nonces in a stateful manner on the client side instead of querying them for every transaction. If custom code for this is not an option, [Orchestrate](https://consensys.net/codefi/orchestrate/) can be used. + +### Use random senders for privacy marker transactions + +To avoid public nonce management, privacy marker transactions can be sent using a [random account per transaction](https://besu.hyperledger.org/en/stable/Reference/CLI/CLI-Syntax/#privacy-marker-transaction-signing-key-file). This option is only available for zero gas networks. + +### Avoid queuing transactions in Tessera + +When Tessera is overloaded with transactions, the performance breaks down catastrophically due to unbounded growth of the request queue. Avoid sending more transactions to Tessera than it can handle. Sudden jumps in submission latency and submission failure rate should be answered with a load reduction on the client side, for example using a back-off scheme. + +Please note that this is not Tessera specific but a general issue in distributed systems. It just happens that if queueing discipline is not maintained, Tessera tends to be the first component to fail. + +### Limit the group size to reduce communication overhead + +Smaller groups need fewer communication for transaction propagation. If reducing the number of Tessera nodes involved in a transaction is an option, it will lead to slightly better tail latencies. Multi-tenancy Tessera can be used to have large groups with a small number of Tessera nodes (possibly only one). + +### Limit group membership changes and make them quick + +Groups are locked (prevented from executing transactions) during membership changes. Try to minimize the number of times the membership changes. When possible, spread load across multiple groups to always have some groups available while others are locked. Consider batching group membership changes if possible.

As with the [`get` call](#1-perform-a-read-operation), you need to use the address that the contract was deployed to and the contract's ABI. The account address must correspond to an actual account with some ETH in it to perform the transaction.

Connect to the node from your local machine via an ingress + +In order to view the Grafana dashboards or connect to the nodes to make transactions from your local machine you can deploy an ingress controller with rules.

Use the following solutions to mitigate this limitation: + +- Disallow discovery and use static nodes to allow only TCP traffic. This isn't an issue for load balancers or exposing nodes publicly. +- If you need to use discovery, use something such as [CNI](#cni) which is supported by all major cloud providers, and the cloud templates already have CNI implemented. + +### CNI + +With the traditional `kubenet` networking mode, nodes get an IP from the virtual network subnet. Each node in turn uses NAT to configure the pods so that they reach other pods on the virtual network. This limits where they can reach but also more specifically what can reach them. For example, an external VM which must have custom routes does not scale well. + +![without-CNI](../../../assets/images/kubernetes-1.jpeg) + +CNI, on the other hand, allows every pod to get a unique IP directly from the virtual subnet which removes this restriction. Therefore, it has a limit on the maximum number of pods that can be spun up, so you must plan ahead to avoid IP exhaustion. + +![with-CNI](../../../assets/images/kubernetes-2.jpeg) + +## Multi-cluster + +You must enable [CNI](#cni) to use multi-cluster, or to connect external nodes to an existing Kubernetes cluster. To connect multiple clusters, they must each have different CIDR blocks to ensure no conflicts, and the first step is to peer the VPCs or VNets together and update the route tables. From that point on you can use static nodes and pods to communicate across the cluster. + +The same setup also works to connect external nodes and business applications from other infrastructure, either in the cloud or on premise. + +![multi-cluster](../../../assets/images/kubernetes-3.png) + +## Concepts + +### Namespaces + +In Kubernetes, [namespaces](https://kubernetes.io/docs/concepts/overview/working-with-objects/namespaces/) provide a mechanism for isolating groups of resources within a single cluster. Both namespaces and resources (for example, Stateful Sets or Services) within a namespace must be unique, but resources across namespaces don't need to be. + +:::note + +Namespace-based scoping is not applicable for cluster-wide objects (for example, Storage Class or Persistent Volumes). + +::: + +### Nodes + +Consider using Stateful Sets instead of Deployments for Besu. The term 'client node' refers to bootnode, validator and member/RPC nodes. For Besu nodes, we only use CLI arguments to keep things consistent. + +### Role-based access controls + +We encourage using role-based access controls (RBACs) for access to the private key of each node, that is, only a specific pod or statefulset is allowed to access a specific secret. + +If you need to specify a Kube configuration file for each pod, use the `KUBE_CONFIG_PATH` variable. + +### Storage + +We use separate data volumes to store the blockchain data. This is similar to using separate volumes to store data when using docker containers natively or docker-compose. This is done for a few reasons: + +- Containers are mortal and we do not want to store data on them. +- Kubernetes host nodes can fail and we want the chain data to persist. + +Ensure that you provide enough data storage capacity for all nodes on the cluster. Select the appropriate type of [Storage Class](https://kubernetes.io/docs/concepts/storage/storage-classes/) based on your cloud provider. In the templates, the size of the [volume claims](https://kubernetes.io/docs/concepts/storage/persistent-volumes/#persistentvolumeclaims) is set to 20Gb by default; you can change this depending on your needs. If you have a different storage account than the one in the charts, you may edit those [Storage Classes](https://github.com/ConsenSys/quorum-kubernetes/blob/5920caff6dd15b4ca17f760ad9e4d7d2e43b41a1/helm/charts/besu-node/templates/node-storage.yaml). + +When using Persistent Volume Claims, set the `allowVolumeExpansion` to `true`. This helps keep costs low and enables growing the volume over time rather than creating new volumes and copying data across. + +### Monitoring + +We recommend deploying metrics to get an overview of the network, nodes, and volumes. You can also create alerts. + +Besu publishes metrics to Prometheus, and you can configure metrics using the kubernetes scraper configuration. We also have custom Grafana dashboards to monitor the blockchain. + +:::note + +Refer to `values/monitoring.yml` to configure the alerts per your requirements (for example slack or email). + +::: + +```bash +cd helm +helm repo add prometheus-community https://prometheus-community.github.io/helm-charts +helm repo update +helm install monitoring prometheus-community/kube-prometheus-stack --version 34.10.0 --namespace=besu --create-namespace --values ./values/monitoring.yml --wait +kubectl --namespace besu apply -f ./values/monitoring/ +``` + +You can configure Besu to suit your environment.

Setting to Retain will keep volumes even if PVCs/PVs are deleted in kubernetes. Setting to Delete will remove volumes from EC2 EBS when PVC is deleted +``` + +Follow the steps outlined in the [deploy charts](charts.md) tutorial to deploy the network. + +## Best practices + +The most important thing is to plan your network out on paper first and then test it in a Dev cluster to make sure connectivity works with your applications and you get the required throughput in transactions per second (TPS). We also recommend you test the entire process, from provisioning infrastructure to updating nodes on a Dev cluster, prior to launching your production network. + +By default, the cloud Kubernetes clusters take care of availability and do multi-zones within a region. The scheduler also ensures that deployments are spread out across zones. Where possible, we recommend you use multiple bootnodes and static nodes to speed up peering. + +You can connect to APIs and services outside the cluster normally, but connecting into your network (such as adding an on-premise node to the network) might require more configuration. Please check the [limitations](index.md#limitations) and use CNI where possible. To connect an external node to your cluster, the easiest way is to use a VPN as seen in the following [multi-cluster](#multi-cluster-support) setup. + +Finally, we recommend setting up monitoring and alerting from the beginning, so you can get early warnings of issues rather than after failure. We have a monitoring chart which uses Grafana and you can use it with Alertmanager to create alerts or alternatively alert via Cloudwatch or Azure Monitoring. + +## Multi-cluster support + +When CNI is used, multi-cluster support is simple, but you have to cater for cross-cluster DNS names. Ideally, you want to create two separate VPCs (or VNets) and make sure they have different base CIDR blocks so that IP addresses don't conflict. Once done, peer the VPCs together and update the subnet route table, so they are effectively a giant single network. + +![multi-cluster](../../../assets/images/kubernetes-3.png) + +When you [spin up clusters](cluster.md), use [CNI](index.md#limitations) and CIDR blocks to match the subnet's CIDR settings. Then deploy the genesis chart on one cluster and copy across the genesis file and static nodes config maps. Depending on your DNS settings, they might be fine as is, or they might need to be actual IP addresses. That is, you can provision cluster B only after cluster A has Besu nodes up and running. + +Deploy the network on cluster A, and then on cluster B. Besu nodes on cluster A should work as expected, and Besu nodes on cluster B should use the list of peers provided to communicate with the nodes on cluster A. + +Keeping the list of peers on the clusters live and up to date can be challenging, so we recommend using the cloud service provider's DNS service such as Route 53 or Azure DNS and adapting the charts to create entries for each node when it comes up. diff --git a/versioned_docs/version-24.6.0/private-networks/tutorials/kubernetes/quorum-explorer.md b/versioned_docs/version-24.6.0/private-networks/tutorials/kubernetes/quorum-explorer.md new file mode 100644 index 00000000000..6cc0430e8f0 --- /dev/null +++ b/versioned_docs/version-24.6.0/private-networks/tutorials/kubernetes/quorum-explorer.md @@ -0,0 +1,69 @@ +--- +title: Use the Quorum Explorer +sidebar_position: 4 +description: Using the Quorum Explorer on a Kubernetes cluster +tags: + - private networks +--- + +# Use the Quorum Explorer + +You can use the Quorum Explorer on a Kubernetes cluster. + +## Prerequisites + +- Clone the [Quorum-Kubernetes](https://github.com/ConsenSys/quorum-kubernetes) repository +- A [running Kubernetes cluster](cluster.md) +- [Kubectl](https://kubernetes.io/docs/tasks/tools/) +- [Helm3](https://helm.sh/docs/intro/install/) +- [Existing network](charts.md) + +## Deploy the Quorum Explorer helm chart + +[Quorum-Explorer](https://github.com/ConsenSys/quorum-explorer) as a lightweight blockchain explorer.

An important aspect of proof of stake is the need for validators to provide attestations in a timely and accurate manner. However, missed attestations have become a common occurrence among validators, leading to a loss of rewards and earnings. This page explores the context behind missing attestations. + +## What are attestations? + +Every epoch (6.4 minutes), a validator proposes an attestation to the network. The attestation is for a specific slot (every 12 seconds) in the epoch. The attestation votes in favor of the validator's view of the chain, in particular, the most recent justified block and the first block in the current epoch (known as _source_ and _target_ checkpoints). This information is collected for all participating validators, enabling the network to reach consensus about the state of the blockchain. + +Honest nodes have 1/3 \* `SECONDS_PER_SLOT` (4 seconds) from the start of the slot to either receive the block or decide there was no block produced and attest to an “empty” or “skip” slot. Once this time has elapsed, attesters should broadcast their attestation reflecting their local view of the chain. + +See the [official specification](https://github.com/ethereum/consensus-specs/blob/dev/specs/phase0/validator.md#attesting) for more information about attestations. + +## Attestation rewards + +Around 85% of validators' rewards come from making attestations. Although committee and slot assignments for attesting are randomized, every active validator will be selected to make exactly one attestation each epoch. + +Attestations receive rewards only if they're included in Beacon Chain blocks. An attestation contains three votes. Each vote is eligible for a reward, subject to the following conditions: + +- Getting attestations included with the correct source checkpoint within 5 slots +- Getting attestations included with the correct target checkpoint within 32 slots +- Getting attestations included with the correct head within 1 slot immediately + +Each of these duties carries a reward rate, a portion of the entire "weight denominator," or the sum of weighted rewards for each attestation. The remaining weights relate to participating in sync committees and proposing blocks (excluding any tips/MEV, the bulk of block rewards). The following table (from [Upgrading Ethereum](https://eth2book.info/bellatrix/part2/incentives/rewards/)) breaks down these weights for cumulative rewards: + +| Name | Percentage | Value | +| ---------------------- | ---------- | ------------ | +| `TIMELY_SOURCE_WEIGHT` | 21.9% | `uint64(14)` | +| `TIMELY_TARGET_WEIGHT` | 40.6% | `uint64(26)` | +| `TIMELY_HEAD_WEIGHT` | 21.9% | `uint64(14)` | +| `SYNC_REWARD_WEIGHT` | 3.1% | `uint64(2)` | +| `PROPOSER_WEIGHT` | 12.5% | `uint64(8)` | +| `WEIGHT_DENOMINATOR` | 100% | `uint64(64)` | + +## Incorrect attestations + +If you have attestations with incorrect head votes, your node might be experiencing slow block imports. However, block producers can also be slow to publish blocks, resulting in a majority of validators getting the head vote wrong. A \<100% head vote doesn't necessarily imply a problem with your node. + +In case of a slowdown, identify whether the issue is with the beacon node or the execution client. Block timing logs can be helpful in determining this. + +If you're using [Teku](https://docs.teku.consensys.net/) as a consensus layer client, identify late blocks (the block didn't get to Teku in time) with the following kind of log: + +```bash +Late Block Import *** Block: c2b911533a8f8d5e699d1a334e0576d2b9aa4caa726bde8b827548b579b47c68 (4765916) proposer 6230 arrival 3475ms, pre-state_retrieved +5ms, processed +185ms, execution_payload_result_received +1436ms, begin_importing +0ms, transaction_prepared +0ms, transaction_committed +0ms, completed +21ms +``` + +The time of arrival indicates how much time elapsed after the start of the slot before your node received the block. In this example, the block arrived after 3475ms, which is slower than optimal, but still enough time for Teku to create an attestation 4 seconds into the slot. + +Typically, delayed arrivals occur when the block producer is slow in generating the block. It's also possible that the block was published on time but took longer to propagate to your node through peer-to-peer gossip. If delayed arrivals are a recurring issue, it might be a problem with your node, such as an incorrect system clock, network issues, or a reduction in the number of peers. + +## Conclusion + +Attestations are complicated. Rewards can be impacted by: + +- The contents of a block (how long it takes to compute). +- The hardware processing that block (execution speed). +- How long it takes for the block to arrive to Besu from the consensus layer. +- The arrival time of the block from other consensus layer peers.

Layered transaction pool + +The [layered transaction pool](https://github.com/hyperledger/besu/pull/5290) is the default +transaction pool implementation. +The implementation separates the pool into layers according to value and executability of the transactions. +The first layer keeps only the highest-value transactions that can feasibly go into the next block. +The other two layers ensure Besu always has a backlog of transactions to fill blocks, maximizing the amount of fees. + +Layered pools have additional parameters that allow you to limit and configure the number of transactions in

See [issue #4375](https://github.com/hyperledger/besu/issues/4375). +- You're using [checkpoint sync](../../get-started/connect/sync-node.md#checkpoint-synchronization), which doesn't download all historical block data, so your peers may disconnect you when fetching those blocks. +- Your node is experiencing the normal behavior of peers connecting and disconnecting. This is especially normal soon after you start your node. + +You can try the following to find more peers: + +- Set [`p2p-host`](../../reference/cli/options.md#p2p-host) to your external IP address to allow inbound connections. +- Restart Besu. This can take a while to build up again. +- Set `-Xdns-enabled` to `true` (only for private networks). +- Delete the node key (which is autogenerated in your data directory). There are two reasons that this might help find more peers: + 1. Your node (identified by the address associated with this key) has been put onto other peers' bad peer lists for some reason. + 2. Peer discovery is influenced by the value of the node key. This is related to the node "distance" in the [discovery algorithm](https://github.com/ethereum/devp2p/wiki/Discovery-Overview#kademlia). + +You can read the [Prysm EL and CL peering documentation](https://docs.prylabs.network/docs/prysm-usage/p2p-host-ip) for more information. + +### "What network or router/modem settings should I check?" + +Check the following settings: + +- Your machine and router's specified DNS should support TCP. You can check your DNS online for TCP support. Google and Cloudflare, 8.8.8.8 and 1.1.1.1, support TCP over port 853. Other DNS might as well. +- The appropriate ports should be open on your router, or your router should have UPNP enabled. See the next FAQ for more information on router settings. +- If you use [Docker](https://docs.docker.com/network/network-tutorial-host/) or virtualization, the container should be able to create outbound connections on the host machine. + +### "Which URLs should I check?" + +Check that the [enode URLs](../../concepts/node-keys.md#enode-url) specified for [bootnodes](../../../private-networks/how-to/configure/bootnodes.md) or [static nodes](../connect/static-nodes.md) match the enode URLs displayed when starting the remote nodes. + +### "How do I open/forward my ports?" + +If you’re behind NAT, you probably need to set up port forwarding in your router. You might also need to configure your firewall. Forward and open `30303` (if using the default p2p port) for both UDP and TCP. If your router supports UPNP, you can set [`--nat-method`](../../reference/cli/options.md#nat-method) to [`UPNPP2PONLY`](../connect/specify-nat.md#upnp). + +### "How do I test that my ports are open?" + +You can use this [open port checker](https://www.yougetsignal.com/tools/open-ports/). + +### "What's the ideal number of peers for Besu?" + +The default maximum is 25. Increasing the number of peers increases the bandwidth, CPU, and disk access Besu uses to respond to peers. Hardware with low specifications might result in low peer numbers. You'll experience diminishing returns with a larger number of peers (>100). + +### "What's the benefit of increasing the number of peers?" + +Increasing the number of max peers won't speed up Besu syncing, because the bottleneck during sync is disk IO and CPU. + +Note that Besu's peers are only used for the initial sync and transaction gossip, neither of which affects attestation performance. The beacon node connectivity controls how quickly you receive blocks and how attestations are published. Increasing Besu's peer count increases the load on your node, which may hurt attestations. + +## Metrics + +Capture [metrics](../monitor/index.md) to gain insights into peering behavior over time. + +To [enable Prometheus to access Besu](../monitor/metrics.md), open the metrics port or metrics push port to Prometheus or the Prometheus push gateway on TCP. + +Specify the ports for Prometheus and Prometheus push gateway using the [`--metrics-port`](../../reference/cli/options.md#metrics-port) and [`--metrics-push-port`](../../reference/cli/options.md#metrics-push-port) options. The defaults are `9545` and `9001`. diff --git a/versioned_docs/version-24.6.0/public-networks/how-to/troubleshoot/performance.md b/versioned_docs/version-24.6.0/public-networks/how-to/troubleshoot/performance.md new file mode 100644 index 00000000000..d324e2aaf4d --- /dev/null +++ b/versioned_docs/version-24.6.0/public-networks/how-to/troubleshoot/performance.md @@ -0,0 +1,45 @@ +--- +description: Troubleshoot poor performance and resource constraints. +sidebar_label: Troubleshoot performance +sidebar_position: 3 +tags: + - public networks +--- + +# Troubleshoot poor performance and resource constraints + +Your hardware, machine environment, and node configuration can affect your node's ability to serve +requests and perform [validator duties](../../concepts/proof-of-stake/index.md), including +[attestation performance](../../concepts/proof-of-stake/attestations.md). + +If you notice high resource usage when [monitoring your node](../monitor/index.md), you can +try the following suggestions: + +* Disable swapping. + Besu is an I/O intensive application, especially during sync, enabling swapping hurts Besu's performance. + You can disable swap at the OS level. + [This article](https://www.tecmint.com/disable-swap-partition/) provides information on how to + disable swap (and caveats). +* Use a high performance SSD disk with NVMe, since Besu's performance bottleneck is often slow disk I/O. +* Configure memory and RAM: + * If you have RAM constraints, use [OpenJ9](../../get-started/system-requirements.md) if you're + running on `x86_64` Linux architecture to reduce memory usage. + * Review and change your [Java heap size](../configure-java/manage-memory.md) if necessary. + 5GB is an appropriate limit. + Higher values may improve sync time, but can be reduced after completing sync. + * Ensure Besu is using [jemalloc](../../get-started/install/binary-distribution.md). + * If you have 32GB RAM or more, set the `Xplugin-rocksdb-high-spec-enabled` configuration option + to `true`. + Don't use this on RAM machines with 16GB RAM or less if you're running a consensus client on the + same hardware. +* If you're running on ARM64, make sure the glibc version is greater than 2.29. + If not, Besu uses a Java implementation instead of the native one for some precompiled contracts, + which results in lower performance. + * On Ubuntu, run `ldd --version`. + See [the methods for other environments](https://dev.to/0xbf/how-to-get-glibc-version-c-lang-26he). +* Pay attention to what processes are running on the same machine/VM as Besu. + Java applications, with default settings, are designed to run alone on the machine. + You can run your consensus client on the same machine, but this adds overhead on Besu, and vice + versa (on CPU cache misses, CPU scheduler latency, IO, etc.). + +You should continue to monitor your node after following these suggestions. diff --git a/versioned_docs/version-24.6.0/public-networks/how-to/troubleshoot/trace-transactions.md b/versioned_docs/version-24.6.0/public-networks/how-to/troubleshoot/trace-transactions.md new file mode 100644 index 00000000000..77c334c50c4 --- /dev/null +++ b/versioned_docs/version-24.6.0/public-networks/how-to/troubleshoot/trace-transactions.md @@ -0,0 +1,48 @@ +--- +title: Trace transactions +sidebar_position: 2 +description: How to trace transactions +tags: + - public networks + - private networks +--- + +# Trace transactions + +To get detailed information about transaction processing, use the [`TRACE` API](../../reference/api/index.md#trace-methods).
