2. History
SNMP4Nagios started when I wanted to
monitor the hardware of a number of hosts. Previous experience had
shown that remote execution via ssh was not performant enough and
SNMP seemed to be the common denominator for most systems involved.
At first I developed shell scripts which used snmpget. This worked
for a while, but around the 20th
monitored machine the monitoring server was no longer able to cope
with the load. Considering this a challenge, I started to rewrite
the plugins using C. People kept asking “Can you monitor
whatever?” and I kept answering
“Configure SNMP and allow the server
to access the agent, then I will check it.” and thus plugins
for various platforms were developed.
2.1. What's New?
2.1.1. Version 0.4,
2007-05-09
- Added plugins for Net-SNMP/lm-sensors.
- Added plugins for Cisco VPN Concentrators.
- Added memory check for Windows/SNMP Informant.

Cisco CPU usage.
Incompatible change: The scanner
interface of check_cisco_cpuusage was
changed to report whether the old or new OIDs should be queried.
-
Incompatible change: The scanner
interface of check_cisco_mem was changed to
report an alternate memory pool.
- Fixed a lot of bugs.
- James T. Saint-Rossy contributed a patch which
allows SNMP4Nagios to compile on Solaris 9.
Thank you James!
