Nagios Support Forum

I just installed a new server to host our Nagios 4.0.2 with CentOS 6.5.
It is set up with nagiosQL to manage all the config files. when giving a restart command through nagiosql, nagios will restart but it will not re-load the config files it seems.
It will keep monitoring monitored hosts and services till I give a service restart command from the server shell.

There are no errors that I can see and the only difference with a restart from the console is that it actually kills the processes.

Anyone any ideas ?

There was an issue with this prior to 4.0.2 where a reload(different than restart) was not handling loading\unloading of hosts and services properly. It seems to be fixed with the 4.0.2 release though. I see the log file, but can you confirm that QL is not sending a reload instead? Which command in the QL interface are you using?

Hi there!

Something similar happened to me (Nagios was no restarting from Nagios QL 3.2.0 after upgrade to Nagios Core 4.0.1), so I checked the NagiosQL Support Forum and I found this link: http://www.nagiosql.org/forum8/installa ... mitstart=0 So I did the changes posted and apparently nagios is now restarting from Nagios QL (below the event log from nagios console):

As I said, it seems that Nagios is now restarting but the changes that I´m doing in NagiosQL are not effective into Nagios unless I restart nagios from CLI (doing a service nagios restart, or service nagios stop and then start).

As an additional note, If I do a service nagios reload from CLI... Same thing (host checks and service checks are not taking effect)

Your help will be really appreciated.

Cheers.

Please open your own thread, as this is somewhat different being 4.0.1. Additionally I believe 4.0.2 had a fix that resolved this issue, so I would suggest updating. Checking the changelog is not a bad idea either.

Hi,

I'm also experiencing this issue with Nagios 4.0.2 except I'm not using NagiosQL; instead I'm simply reloading from the linux shell. I went over the changes listed for Bug 492 [http://sourceforge.net/p/nagios/nagiosc ... c89f91d27/], and it seems my init script is all up-to-date, but i'm still not able to see any service or host changes in the nagios web interface unless I stop the service, and then start it up again.

Any ideas?

What platform/os are you running nagios on? I ask because there are still some issues with the init script on suse, debian and friends, among a few others.
