Can I pull the description of a Linux Server?

Hi,

I'm not a Linux person so this is a bit over my head so thought I'd see if anyone here could help.

We have a service called BrokerAdvanced.  There are multiple instances of this service running on each server that we need to monitor.  I modified one of the Linux Process checks that I found that I think was called LinuxNewProcesses_with_Active_Discovery.

The Arguments and Filter section look like this:

and this is the Collection part:

When the check runs, it does pull data, but it looks like this:

We can't tell which one is which and it one stops and starts again, it gets a new PID so it just falls off the list and looks like a new process.

If I go under Add Other Monitoring, and bring up a list of the running processes.  Instead of organizaing these by PID, we'd like to organize them bu the Description of the item like this:

That way, if one stopped and started, hopefully it would still be under the same item since the description (if that's what it is) would be the same.  I'm not a Linux person and don't really know if we can get that information.  The Name seems to be matching on an OID so maybe there's a different OID to get what we are looking for?  Does anyone have any ideas on if we can do this somehow?

Hopefully that all made sense.

Thanks.

    You can use the script type for Autodiscover (instead of snmp) and write code to set WildValue to what you want.

    If it helps, here is one that I use for webservices that perhaps you can start with and modify as needed:

    import com.santaba.agent.groovyapi.snmp.Snmp
def hostname  = hostProps.get("system.hostname")

//Get list of processes from snmp
def OID_NAME  = ".1.3.6.1.2.1.25.4.2.1.4"
def OID_PARAM = ".1.3.6.1.2.1.25.4.2.1.5"
def processPaths  = Snmp.walkAsMap(hostname, OID_NAME, [:], 20000)
def processParams = Snmp.walkAsMap(hostname, OID_PARAM, [:], 20000)

//Get all unique processes
def webServices = []
processPaths.each { pid, name ->
    if (name) {
        webServices << name+"||"+processParams[pid]
    }
}
webServices = webServices.unique()

//Report all processes found, use the FILTERS of the DataSource to only get what we want
webServices.each { entry ->

    //AUTODISCOVER: WildValue_ID##WildAlias_Display##Description##WildValue2##auto.propertyhere=somevalue&auto.propertyhere2=somevalue2"
    def (process,param) = entry.tokenize('||')
    println entry+"##"+process             //+"##"+process+" "+param   (if you want to add full command in desc)
}
return 0
