[Nagiosplug-devel] New Plugin: Check SNMP OperStatus by given IP Address

[Hendrik Baecker]

Hi Lists,

I've just sit down in my sandbox and wrote a little Perl Script to get 
the SNMP Interface Operating Status by a given IP Adress of an Subinterface.

How it began: Until yesterday we were checking our Cisco Router 
Subinterfaces witch the normal check_snmp with the OID to the OperStatus.

Every time a router bootet or other Interfaces went away or comes new, 
possibly the hole configured SNMP IDs for every single Subinterface were 
wrong.
So I had a look how MRTG is working and grepped some idea from it.

The Plugin must be called with 4 Arguments: Host IP, Community, 
Interface IP, Expected Value of OperStatus.

It uses a Mysql DB with a little table to store the last checked SNMP ID 
for the Interfaces, update the table if the ID has changed.

Sorry, but until now there is no realy Project Homepage, just a dead 
link to a private Gaming Site of mine... If I got enough time I will 
perhaps create some Webpage.

Greetings
Hendrik
