Monitoring System Services

Start or Stop Monitoring

To specify what services should be monitored and to start monitoring:

1. Go to Extensions > Watchdog.

   All services controlled by Plesk will be listed on the Services
   tab.

   

2. Specify the services that should be monitored and specify monitoring
   preferences:

   1. Click a service name.
   2. Select the Monitor the service checkbox to set the Watchdog to
      monitor the service.
   3. Select the Save service statistics checkbox if you wish
      Watchdog to keep the information on CPU and RAM resources used by
      the service, and present it in graphical reports (Extensions >
      Watchdog > Statistics).
   4. Select the Stop monitoring the service if it frequently
      restarts option, if you wish Watchdog to stop monitoring the
      service if it fails the specified number of times, and specify the
      failure ratio. Otherwise the Watchdog will bother you with alert
      messages each time it attempts to restart a non-responsive
      service. The default value of five failed attempts should be
      enough.
   5. Specify the time during which Watchdog will be waiting for
      response from the polled service in the Connection timeout
      box. Watchdog polls the service and then is waiting for response
      during the specified amount of time. If Watchdog receives no
      response, it restarts the service. If you host a great number of
      sites and email accounts on your machine, you are recommended to
      set the Connection timeout for Qmail mail server to 120
      seconds, and Apache Web server to 15 seconds, otherwise Watchdog
      will consider the busy services to be malfunctioning and will
      restart them.
   6. Review the commands that Watchdog uses to start and stop the
      service. It is recommended that you leave the prefilled values
      unchanged. You can write custom scripts that, for example, will
      clean up log files or send an SMS to your cell phone before
      actually starting the service, and specify the commands to run
      your scripts in the To start the service, run the command and
      the To stop the service, run the command fields.
   7. If you are using the default commands for running the services,
      leave the predefined value of 60 seconds in the Service startup
      time box. If you are running custom scripts, and they take more
      than 60 seconds to execute, specify the required time in the
      Service…
