Nagios Support Forum

Sorry, it's not 480GB of data *per* night. Bacula on that box stores a vault for three or four boxes which totals 480GB. The nightly jobs are next to nothing, a few gigabytes at the absolute most. Specs: Quad Core Xeon, 32GB RAM, mechanical RAID 5. I'm doing about 54 service checks I think? Hardly a...

Simple 'check_smtp' check failing against a host on TCP 25.

Doesn't compute.

And lots more connection refused errors today. Apart from silencing those checks or turning off SMS for them... which defeats the whole point.

I just don't understand anymore!

On a DNS check this time.

...and pretty much all of those were port 443 / SSL connections.

Hmmmmmmm

Ugh, a good 60 'connection refused' SMS errors last night, on the same few hosts. I'm going to take these down to email only for now. But at this point I have to think about sacking this off and looking at other availability monitoring sadly

Thanks for your suggestions guys. Another Nagios server is certainly possible. That's one option for testing. I'll look into notification_interval also.

I'm not sure if it's relevant but I've changed all the http checks that were checking out OK (but also being redirected via 302 by various rewrite/config rules on the webservers) to specifically check a file. Just to reduce the redirection and such. Mainly because I noticed that these were the check...

I've cheated and set service_check_timeout=65 just to test. Will report back.

Passive checks are an option, I don't currently have any configured.

I did notice that 60 second limit actually on external commands.

I'll play about on Monday!

Have a great weekend guys.
