Monitor arbitrary TCP port

Hi Tom,

This is definitely possible - I am attaching the LM locator code for a "PortMulti"datasource. Once you've imported the datasource, navigate to a device, and select the dropdown next the the big blue 'Manage' button. In the dropdown there is an option to 'Add Monitored Instance' - see the attached screenshot for configuration parameters. For additional ports to monitor, repeat the process.

The datasource name will be 'PortMulti-' and the LM locator code is PX4D7W.

Cheers,

Kerry

I had DIY'd a scripted Groovy datasource ages. Not sure if this was exactly what PortMulti- did, but the results should be similar. 

(host, port) = "##WILDVALUE##".split(':')
try {
    s = new Socket(host, port.toInteger())
    s.close()
    return 0
} catch (ConnectException ce) {
    println ce.toString()
    return 1
} catch (BindException be) {
    println be.toString()
    return 4
} catch (NoRouteToHostException re) {
    println re.toString()
    return 2
} catch (PortUnreachableException pe) {
    println pe.toString()
    return 3
} catch (Exception e) {
    println e.toString()
    return 5
}

You would just then setup a datapoint to capture the exitCode and alert if it was > 0. 

Hi Kerry,

Thank you for the easy to understand answer. Does adding of the monitored instance count as a license slot?

Cheers,

Tom.

Message when attempting to add the Datasource

503 : This LogicModule is currently undergoing security review. It will be available for import only after our engineers have validated the scripted elements.

The LogicModule is now available to me and I can happily report PortMulti- is working well. 

PX4D7W is private now. Any alternative???

This is public now. Try again.

Cant find PX4D7W. This is my first attempt at this, so I am probably doing something wrong. any advise would be helpful

It's there. There's just a different search box for locator codes. (Yes, I know.) In the Exchange, in the top right, there's a locator search option. 

I have enhanced my version of this DS to include automatic discovery using this discovery script:

try{
    hostProps.get("pingmulti.targets").tokenize(",").each{
        target = it.tokenize("|")
        println(target[0] + "##" + target[1])
    }
    return 0
} catch (Exception e){return 1}

Set a property called "pingmulti.targets" in the format:
target1_IP/FQDN|target1_Name,target2_IP/FQDN|target2_Name

This also allows the appliesTo to be simplified to just "pingmulti.targets". 

However, keep in mind that this still only pings from the collector. If you want to ping from the target device to some other destination, consider these two DSs. Only works on Windows or Linux, but that's usually what people are going for.
