MySQL plugin for New Relic

Find the New Relic MySQL plugin in the New Relic storefront

Find the New Relic MySQL plugin in Plugin Central


Your New Relic MySQL plugin can be operational in 2 minutes when following these steps.


Prerequisites

The MySQL plugin for New Relic requires the following:

  • A New Relic account. Signup for a free account at http://newrelic.com
  • A server running MySQL Version 5.0 or greater. Download MySQL for free at http://dev.mysql.com/downloads
  • A configured Java Runtime (JRE) environment Version 1.6 or better
  • Network access to New Relic (authenticated proxies are not currently supported, but see workaround below)

Download

Download and unpack the New Relic plugin for MySQL from Plugin Central: https://rpm.newrelic.com/plugins/

Linux example:

$ mkdir /path/to/newrelic-plugin
$ cd /path/to/newrelic-plugin
$ tar xfz newrelic_mysql_plugin*.tar.gz

Create MySQL user if necessary

The MySQL plugin requires a MySQL user with limited privileges. To use the New Relic default, run the following SQL script located at /scripts/mysql_user.sql.

$ mysql -uroot -p < mysql_user.sql

This script will create the following user:

username: newrelic
host: localhost or 127.0.0.1
password: *B8B274C6AF8165B631B4B517BD0ED2694909F464

You can choose to use a different MySQL user name and password. see MYSQL.TXT for more info.

Configuring your agent environment

The New Relic plugin for MySQL runs an agent process to collect and report MySQL metrics to New Relic. Configure your New Relic license and MySQL databases.

Configure your New Relic license

Specify your license key in the necessary properties file. Your license key can be found under Account Settings at https://rpm.newrelic.com see https://newrelic.com/docs/subscriptions/license-key for more help.

Linux example:

$ cp config/template_newrelic.properties config/newrelic.properties
# Edit config/newrelic.properties and paste in your license key

Configure your MySQL properties

Each running MySQL plugin agent requires a JSON configuration file defining the access to the monitored MySQL instance(s). An example file is provided in the config directory.

Linux example:

$ cp config/template_mysql.instance.json config/mysql.instance.json
# Edit config/mysql.instance.json

If using your localhost MySQL instance, add your user name and password as well as a meaningful name which will appear in the New Relic user interface for the MySQL instance. Set the value for the "name" attribute to match your MySQL databases purpose, e.g. "Production Master".

[
  {
    "name" : "Localhost",
    "host" : "localhost",
    "metrics" : "status,newrelic",
    "user" : "USER_NAME_HERE",
    "passwd" : "USER_PASSWD_HERE"
   },
]

Running the agent

To run the plugin in from the command line: $ java -jar newrelic_mysql_plugin*.jar

If your host needs a proxy server to access the Internet, you can specify a proxy server & port: $ java -Dhttps.proxyHost=proxyhost -Dhttps.proxyPort=8080 -jar newrelic_mysql_plugin*.jar

To run the plugin in from the command line and detach the process so it will run in the background: $ nohup java -jar newrelic_mysql_plugin*.jar &

Note: At present there are no init.d scripts to start the New Relic MySQL plugin at system startup.

Keep this process running

You can use services like these to manage this process.

For support

Fork me!

The MySQL plugin uses an extensible architecture that allows you to define new MySQL metrics beyond the provided defaults. To expose more data about your MySQL servers, fork this repository, create a new GUID, add the metrics you would like to collect to config/metric.category.json and then build summary metrics and dashboards to expose your newly collected metrics.

See CATEGORIES.TXT for more info.
