How to Monitor a Custom Node Application

Scalyr Agent has the capabilities to collect your application process metrics with monitors plugin. For example, to monitor a custom NodeJs application, you can simply add the linux_process_metrics plugin to the agent config file and include the command that starts the Node application.

monitors: [
  {
     module:      "scalyr_agent.builtin_monitors.linux_process_metrics",
     id:          "tomcat",
     commandline: "node",
  }
] 

This config will record resource usage for any process whose command line contains a match for the regular expression node. You should adjust the commandline parameter according to your own environment.

Optional configs such as "aggregate metrics" and "include child process" are also available if you view the metric as a total sum with the sub-processes. Please refer to our official documentation for more information.
