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;

Thanks, Tomas. Works perfectly :)
