Re: Process filters and warnings

[christian pearce]

Weird huh?  It must need a signal in order for it to process the code.

I just tested it.  The HUP signal never gets passed to the cron job. 
But I am not certain this is what you want anyway.  Because this code
will just print out that it found the process running (Read the docs
carefully).  Which is the exact opposite of what you are looking for. 
How about this?

control:

    actionsequence = ( processes )
    domain         = ( blackrock.com )
    sysadm         = ( root@locahost )
    inform         = ( on )
    warnings       = ( on )

filters:

    #*********************************************
    # Process filter aliases
    #*********************************************
    {
        pcron
            Owner:   "root"
            Command: "crond"
            Result:  "Owner.Command"
    }

processes:

    #---------------------------------------------
    # All hosts must be running these proces
    #---------------------------------------------
    any::
        "cron"
            filter=pcron
            action=signal
            signal=cont
            elsedefine=cron_not_running

alerts:

    cron_not_running::
        "Cron is not running."

But this code as the unfortunate circumstance of sending the CONT
signal if it is running.

If you didn't like that you could use a shellcommand that ran ps and
greped for what you were looking for.  If it wasn't successful do a
elsedefine=cron_not_running
