Simple check to see if a service is running

Sensu Classic (EOL)
1

Hello! I am new to sensu, I have managed to install it on the Server and Client and the Keep Alive works great.

Is anyone able to show me an example of a simple check which checks if the service ssh or postfix is running? I have not been able to find an simple example yet. Thanks alot.

Most people are probably using the nagios check_procs plugin.

{
  "checks": {
    "sshd-min1-max12": {
      "command": "PATH=$PATH:/usr/lib64/nagios/plugins check_procs -C
sshd -c 1:12",
      "handlers": [
        "bby"
      ],
      "subscribers": [
        “web"
      ],
      "interval": 60,
      "refresh": 1800,
      "occurrences": 2
    }
  }
}

This is using sensu. You can use any of the nagios plugins with Sensu.

It’s talked about here: http://sensuapp.org/docs/latest/checks

Thanks! One fast question for you. Do I need both the plugin and check configuration on both client and the server ?

I copy-pasted the plugin and changed the service to “ssh”, and the configurtion. But I am getting this error in sensu: Dropbox - Error - Simplify your life

The answer would depend on what type you are using. There are
stand-alone checks and subscriptions.

At the top of these articles, you will see bullet points of what are needed:

I copy-pasted the configuration you linked to but changed the service to ssh. It’s not working at all. Dropbox - Error - Simplify your life

This is literally the first task in the Documentation after installing Sensu:

http://sensuapp.org/docs/latest/adding_a_check

Replace “crond” in that example with “sshd” or whatever.
