A Helm chart to deploy the New Relic Kubernetes monitoring solution
You can install this chart using nri-bundle located in the
helm-charts repository or directly from this repository by adding this Helm repository:
helm repo add nri-kubernetes https://newrelic.github.io/nri-kubernetes
helm upgrade --install newrelic-infrastructure nri-kubernetes/newrelic-infrastructure -f your-custom-values.yaml- https://github.com/newrelic/nri-kubernetes/
- https://github.com/newrelic/nri-kubernetes/tree/main/charts/newrelic-infrastructure
- https://github.com/newrelic/infrastructure-agent/
This chart implements the New Relic's common Helm library which means that it honors a wide range of defaults and globals common to most New Relic Helm charts.
Options that can be defined globally include affinity, nodeSelector, tolerations, proxy and others. The full list can be found at
user's guide of the common library.
There are two mechanisms to reduce the amount of data that this integration sends to New Relic. See this snippet from the values.yaml file:
common:
config:
interval: 15s
lowDataMode: falseThe lowDataMode toggle is the simplest way to reduce data send to Newrelic. Setting it to true changes the default scrape interval from 15 seconds
(the default) to 30 seconds.
If you need for some reason to fine-tune the number of seconds you can use common.config.interval directly. If you take a look at the values.yaml
file, the value there is nil. If any value is set there, the lowDataMode toggle is ignored as this value takes precedence.
Setting this interval above 40 seconds can make you experience issues with the Kubernetes Cluster Explorer so this chart limits setting the interval inside the range of 10 to 40 seconds.
The New Relic common library allows to set affinities, tolerations, and node selectors globally using e.g. .global.affinity to ease the configuration
when you use this chart using nri-bundle. This chart has an extra level of granularity to the components that it deploys:
control plane, ksm, and kubelet.
Take this snippet as an example:
global:
affinity: {}
affinity: {}
kubelet:
affinity: {}
ksm:
affinity: {}
controlPlane:
affinity: {}The order to set an affinity is to set first any kubelet.affinity, ksm.affinity, or controlPlane.affinity. If these values are empty the chart
fallbacks to affinity (at root level), and if that value is empty, the chart fallbacks to global.affinity.
The same procedure applies to nodeSelector and tolerations.
On the other hand, some components have affinities and tolerations predefined e.g. to be able to run kubelet pods on nodes that are tainted as control plane nodes or to schedule the KSM scraper on the same node of KSM to reduce the inter-node traffic.
If you are having problems assigning pods to nodes it may be because of this. Take a look at the values.yaml to see if the pod that is
not having your expected behavior has any predefined value.
In versions below v3, changing the privileged mode affected the hostNetwork. We changed this behavior and now you can set pods to use hostNetwork
using the corresponding flags from the common library
(.global.hostNetwork and .hostNetwork) but the component that scrapes data from the control plane has always set hostNetwork enabled by default
(Look in the values.yaml for controlPlane.hostNetwork: true)
This is because the most common configuration of the control plane components is to be configured to listen only to localhost.
If your cluster security policy does not allow to use hostNetwork, you can disable it control plane monitoring by setting controlPlane.enabled to
false.
The default value for privileged from the common library is
false but in this particular this chart it is set to true (Look in the values.yaml for privileged: true)
This is because when kubelet pods need to run in privileged mode to fetch cpu, memory, process, and network metrics of your nodes.
If your cluster security policy does not allow to have privileged in your pod' security context, you can disable it by setting privileged to
false taking into account that you will lose all the metrics from the host and some metadata from the host that are added to the metrics of the
integrations that you have configured.
