Cisco Info PropertySources

@Tom Lasswell I noticed it wasn't pulling anything for switch stacks so I modified it a bit to get around that.  Of course, this will only show the data for the stack master, but it can definitely still be useful.  I know there's a separate datasource that pulls the data for all the units in each stack, but oh well - better to have it twice than not at all!

import com.santaba.agent.groovyapi.snmp.Snmp;

// set hostname variable.
def hostname = hostProps.get("system.hostname")

// Wrap code in try/catch in case execution experiences an error.
try
{
    // OID which contains the serial number of Cisco devices.
    def entPhysicalSerialNum = "1.3.6.1.2.1.47.1.1.1.1.11.1"
    
    // Initiate SNMP GET command.
    def output = Snmp.get(hostname, entPhysicalSerialNum);
  	
  // Null response could mean switch stack.
    if (output == null)
        try
        {
            def entPhysicalSerialNum2 = "1.3.6.1.2.1.47.1.1.1.1.11.1001"
            def output2 = Snmp.get(hostname, entPhysicalSerialNum)
            println "auto.Cisco_Serial_Number=" + output2
        }
        catch (Exception e)
        {
            // print out the exception.
            println e;
            return 1;
        }
    // Print out the serial number.
    println "auto.Cisco_Serial_Number=" + output
}

// Catch the exception.
catch (Exception e)
{
    // print out the exception.
    println e;
    return 1;
}

// exit code 0
return 0;
