What kind of notifications are you doing and how many are you sending out? Why does a notification cycle take 9 seconds to complete? <div class="gmail_quote">On Sat, Jan 23, 2010 at 12:13 AM, Mike Lindsey <<a href="mailto:mike-nagios@5dninja.net">mike-nagios@5dninja.net</a>> wrote: <blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">What kind of options does one have, if your master nagios server is getting overloaded? I have half a dozen slaves doing polling, submitting passive check results back via send_nsca. The master does no active polling, just event processing, notifications, and web ui. Under normal circumstances, it works alright. But after a restart it can take up to half an hour before the master catches up; and if there are a lot of events, the act of sending out notifications can cause it to fall behind. I'm pre-caching my object file, I'm skipping circular dependency checks, and I've gotten a notification cycle down to 9 seconds. I tried modifying nagios to fork before notifications, but that failed pretty spectacularly; so that 9 seconds is a time where 900 or so passive check submissions block until the notifications are done. Are there any options for running a dual-master setup, or other ways to spread the load across multiple machines? Has anyone patched nsca to submit check results into the checkresults directory, instead of via the nagios.cmd pipe? What kind of improvement can one expect from that?
