Linux Process Monitoring

You can configure MetricsHub to monitor a Linux process. In the example below, we configured MetricsHub to monitor the systemd process running on the prod-web resource using SSH.

Procedure

To achieve this use case, we:

  • Declare the resource to be monitored (prod-web)​ and its attributes (host.name, host.type)​
    resources:
      prod-web:
        attributes:
          host.name: prod-web
          host.type: linux
  • Configure the SSH protocol with credentials and timeout​
        protocols:
          ssh:
            username: <username>
            password: <password>
            timeout: 30
  • Add a new instance of the LinuxProcess[1] connector for the monitoring of systemd. Name this new instance systemdProcess, for example:
        additionalConnectors:
          systemdProcess: 
            uses: LinuxProcess
  • Set the variable matchName for the service to be monitored (systemd):
            variables:
              matchName: systemd

Here is the complete YAML configuration:

    resources:
      prod-web:
        attributes:
          host.name: prod-web
          host.type: linux
        protocols:
          ssh:
            username: <username>
            password: <username>
            timeout: 30
        additionalConnectors:
          systemdProcess: 
            uses: LinuxProcess
            variables:
              matchName: systemd
