All, I have a moderately loaded Nagios server, and a home-brew 'environmental healthcheck' plugin. This plugin walks a table, checks a user-supplied column, and returns data based on that column. For example, pointed at IF-MIB::ifTable and given 'ifOperStatus' and a hash, it could return 'OK' for 'up', 'WARN' for 'testing' and 'CRIT' for 'down'.
The plugin takes around 0.5s of CPU time in total when measured with 'perl -d:DProf'. There are 36 calls to SNMP::init_snmp, which seems like a heck of a lot, and it's taking up 80% of CPU time. A bare-bones test script only calls init_snmp three times. The issue I'm up against is that when multiple copies of this plugin run, they take increasingly longer (up to 6-7 seconds) to return any data, whereas a plugin that uses Net::SNMP (the 'other' perl module) is much quicker. I could re-code my plugin, but I'd rather stick to Net-SNMP as I've done for the past decade. Can anyone help? The code is at http://stash.poggs.com/check-environment.pl and will be there for a week or two.
