Re: Sporadic 'Connection refused' errors in 4.2.4

Same host just got the same connection refused error - same error 11 in syslog too check_http works fine from the command line, as does telnet. Funny how it was this one at 4AM this morning too.

Re: Sporadic 'Connection refused' errors in 4.2.4

Yesterday I tweaked a few timeouts on checks to be higher. I got a single failed->ok email only notification pair for one host - which is in a service check with two other hosts. The two other hosts checked out fine. Same old connection refused error, same Error 11's in syslog. Jan 10 04:21:38 REDAC...

Thanks, I'll check this out and try contribute to the github issues.

Will report back tomorrow and see how Nagios does.

Re: Sporadic 'Connection refused' errors in 4.2.4

Debug level is set to 0, I did have it enabled yesterday while I was doing some diagnostics. I could see the failure in there, but not the cause why, just the informational string really.

Will have another play with it. Strange though, I'm sure nagios.log would move a bit too.

Re: Sporadic 'Connection refused' errors in 4.2.4

Hi, It's running bacula as well which runs in the evening. But only for about 480GB of data. I believe it's CentOS 6.8, updated with yum-cron, nagios is built from source each time. I've just increased some timeouts on the few commands I've noticed that sometimes fail, and changed a few from check_t...

Re: Sporadic 'Connection refused' errors in 4.2.4

Another thing. use_syslog is off and it's still logging to /var/log/messages after a service restart. It's always been off however.

Re: Sporadic 'Connection refused' errors in 4.2.4

https://support.nagios.com/forum/viewtopic.php?f=7&t=39856 Seems related to this. But from what I can read these error 11's are informational rather than anything. I just cannot understand why I get these 'connection refused' errors 1% of the time at most. I can't see anything changing on the bo...

Sporadic 'Connection refused' errors in 4.2.4

Hi there, First post so be gentle with me. I have a Nagios 4.x install which I've been running for a few years. It is currently upgraded to 4.2.4 which I believe is current. Every so often I get false positives via check_http plugin which are usually 'connection refused' - this 'mainly' seems to hap...
