Groovy SNMPwalk Helper Functions

tl;dr - Go here.

I've been doing a lot of SNMP polling through Groovy lately. One of the methods I use most often is Snmp.walkAsMap(), which returns a map that looks like this:

This great and usable, but I found myself constantly wanting to display the data easier. I also wanted the data to be structured a little more hierarchically, grouping by row in the SNMP table.  I also wanted to make it easier to address individual pieces of the data. I built a couple helper functions that transform the data and make it easier to address. They can be found here.




The output of the snmpMapToTable() function looks like this:

It may not look much better, but if you add some carriage returns and tabs you get this:

As you can see, it's getting easier to see what's going on. At this point, it'd be nice to order by instance ID and also order by metric ID.  One of the helper functions I built does just that, pprintSnmpWalkTable:

For me, this is pretty easy to read and find individual values that I'm looking for. The three lines that resulted in the above output were these:
walkResult = Snmp.walkAsMap(host, Oid, props, timeout)
entryRaw = snmpMapToTable(walkResult)
pprintSnmpWalkTable(entryRaw)



Accessing the data is pretty easy now:
ifEntryRaw.each {wildvalue, data ->
    println("""Interface ${wildvalue}:
 ifAlias: ${ifXEntryRaw[wildvalue]["1"]}
 ifDescr: ${data["2"]}
 ifType: ${data["3"]}
    """)
}
