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!

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

Run it manually 1000 times, checks out fine each and every time. Sat in nagios as red / critical.

Doesn't compute.

I would like to take a step back.

It's running bacula as well which runs in the evening. But only for about 480GB of data.


480GB is quite a bit of data, and depending on how it's prioritizing your traffic / IO, this could definitely affect the Nagios checks.

- How much resources do you have allocated to this machine? (ram + CPU + disks)
- How many checks do you have running on this machine? (host and service)
- What is the full output of ps -eo pcpu,args --sort=-%cpu and this command -
Code: Select all
ps axo rss,comm,pid | awk '{ proc_list[$2]++; proc_list[$2 "," 1] += $1; } \
END { for (proc in proc_list) { printf("%d\t%s\n", \
proc_list[proc "," 1],proc); }}' | sort -n | sort -rn | awk '{$1/=1024;printf "%.0fMB\t",$1}{print $2}'


- Do you have local checks running against the Nagios machine to see where the resources are peaking at all?

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 anything.

Re: Sporadic 'Connection refused' errors in 4.2.4

Postby tgriep » Fri Jan 27, 2017 3:09 pm

Can you post the full /var/log/message and the nagios.log file when the timeout happened so we can view them and get better details on what is happening?
If you don't want to post them, can you PM them to me?

The only thing I saw in the nagios.log file at the same time the error was in the messages log is the following.
Code: Select all
SERVICE NOTIFICATION: external;www.xxx.xxx;HTTPS check;CRITICAL;notify-service-by-email;connect to address www.xxx.xxx and port 443: Connection refused

Take a look at the notification settings and verify that they are correct.

Also, how do you mean by check notifications? The emails and SMS that are sent seem to have the correct information.

Thanks.
