Count SNMP walk results
-
Hi,
As a new user to NetXMS I still cannot believe just how easy it is to use. I have been looking for a replacement to the old RRD based systems for a while and this is blowing everything else away. I just have a couple of things I am struggling to get worked out (custom scripting seems the way to go with these) that I would like to iron out before I add it to my production. I have split them in to two posts to keep it simpler.
This topic is an SNMP Walk query. I am trying to work out how I can count the lines in a SNMP Walk. For example, I might want to count the number of Arp entries where no SNMP OID exists. I would like to be able to get just a count as an integer from walking 1.3.6.1.2.1.4.22.1.2. Is this possible?
Many thanks.

Very easy with a "Script" type DCI.
Just create a script named "count_ARP_entries" in the script library, and used that for the DCI parameter.
(DCI origin will of course be "Script")For the script, you can do this:
walk_oid = "1.3.6.1.2.1.4.22.1.2"; tube = CreateSNMPTransport($node); if (tube == null) return null; varbinds = SNMPWalk(tube, walk_oid); if (varbinds == null) return null; return varbinds->size;Refferences:

Thanks, Tomas. Works perfectly
