Re: Statistics Monitoring Integrations

You can collect statistics through remote JMX. Use IGNITE_JMX_PORT environment variable to set port. Seems like DataDog able to connect to remote Mbeans server. There are should be 3rd party plugins for NewRelic. -- Sent from: http://apache-ignite-users.70518.x6.nabble.com/
