Yes, I agree. I'll keep it. > Regarding your fix: > The timeout option does appear to get passed to SNMP, however the > actual timeout is twice what is specified.

I can't see anything obviously wrong > with your code, but it behaves this way both on both SLES 11 SP1 (Perl > 5.10, net-snmp 5.4.2.1, Net::SNMP 6.0.1) and OS X 10.8 (Perl 5.12.4, > net-snmp 5.6, Net::SNMP 6.1 [from CPAN]). Hmm.. kind of confusing. It is due to the fact that Net::SNMP does one retry (with the same timeout) before it bails out. This is adjustable with the '-retries' parameter to the SNMP object. The default is 1. If I set it to 0, the plugin times out in the SNMP object at the specified time as you would expect. Thanks for pointing this out, I should make a note of it in the manual page. > You probably also want to add this option to the help/usage message. I won't make the help output, as that only covers the most popular options, but I'll add it to the manual page. Cheers, -- Trond H.
