Cassandra Nodetool Integration

This New Relic Infrastructure integration invokes the cassandra nodetool utility to gather cassandra node status metrics.

Installation

• Download an archive file for the Cassandra-Status Integration
• Place the executables under bin directory and the definition file cassandra-status-definition.yml in /var/db/newrelic-infra/newrelic-integrations
• Set execution permissions for the binary file nr-cassandra-status
• Place the integration configuration file cassandra-status-config.yml.sample in /etc/newrelic-infra/integrations.d

Getting Started

In order to use the Cassandra-Status Integration it is required to configure cassandra-status-config.yml.sample file. Firstly, rename the file to cassandra-status-config.yml. Then, depending on your needs, specify all instances that you want to monitor. Once this is done, restart the Infrastructure agent.

Usage

You can view your data in Insights by creating your own custom NRQL queries. To do so use CassandraStatusSample event types.

The following attributes are reported always

• Status: 0 (not reported) if there is an error executing nodetool info or nodetool status commands 1 if the commands execute succesfully and return a status of "Down" 2 if the commands execute successfully and return a status of "Up"

• State : 0 (not reported) if there is an error executing nodetool info or nodetool status commands 1 if the commands execute successfully and return a state of N 2 if the commands execute successfully and return a state of L 3 if the commands execute successfully and return a state of J 4 if the commands execute successfully and return a state of M

If the command execute succesfully, then the following attributes are also parsed, They will not be reported however if the commands fails for any reason,
