Additionally things like some of the Nagios snmp checks will get upset about seeing a string when you want to look at a number (ie: check_snmp can alert you if something is out of range, but on a string, it's always out of range). > You'd need to adjust the 'qm-stat-cat' script to return the numeric > value as the *exit* status from the script, and then retrieve (and monitor) > the OID UCD-SNMP-MIB::ucdavis.9100.1.100 OK, now I understand what you're saying. The problem I have is that this script is looking at qmail queues and grabbing some custom stats - and it's got a multi-line output, kind of like so: /var/log/qmail/qmail1/current 400/400 66234 1766 69 68069 3 0 68069 And we have from 1 to 9 queues on each host... So I'd be looking at a pretty major restructuring of how we do this. I saw another poster had a quick hack/fix for mrtg; have mrtg run a script that wraps around snmpget and you're set. But then we still have to deal with nagios and the like. If I really want to have certain lines in a script that returns multiple lines be reported as integers, is there *anything* I can do to force that? Is there something beyond exec and extend that would make more sense?
