Nagios Support Forum

I've been having this problem for a while now since the upgrade to 4.x, I use nagiosql to edit our configuration but when I'm done I have to use the console to restart Nagios or it will not pick up on changes.
It restarts the service but for some reason it just won't pick up on config changes... It's been a while but I think I had to mod nagiosql to actually get it to send a restart command that nagios actually picked up on when 4 was first released .. but going by memory and never really bothered with it as I usually have an ssh session open any ways.

I'd still like to get this to work now though, so if anyone has any ideas

[edit]
Forgot to mention, restart through the Nagios service webpage itself does exactly the same as a restart from nagiosql, which is 'not reloading the config'
Also running 4.0.7 right now, just found out .8 has been released but need to update it still.

According to the code, using the webui button should react by flushing memory, reloading configs, and restarting of monitoring. I will have to give this a few tests, to see if the functionality has been changed. I will post back here after testing.

Anyone have any ideas for this ? Updated to 4.0.8 and this problem remains.

1. If you restart the nagios service from the CLI, do the new configs get loaded? If not, nagiosql may be writing the configs to the wrong location or not at all.
2. When you upgraded to 4.0.7, did you update the init script with:

Code: Select all

make install-init

Yes command line restart works fine.
It is just the restart through a webpage that does not.

Looks like you have double posted this question, in your previous thread, did you try any of the suggestions put forth by other users? If so, which ones?:

In the future, we do ask that you do not double post your questions, the duplicate will be removed, in this case, since we are already so far along in this one, we will keep them open.

As abrist mentioned, did you happen to do a make install-init? This will write out the init scripts for proper starting, if you were using an old version some settings or permissions might be incorrect that the init script is setting. Running the following should tell us fairly quickly as well:

Code: Select all

ls -lart /etc/init.d/nagios

Same issue on nagios 4.1.1 . Maybe someone is alredy solved this problem?

Can you please describe more about what you're experiencing? What are you using with Nagios? What is the output for ls -lart /etc/init.d/nagios?

It's been so long since I've looked at this as I had just given up trying to fix the web/socket restart.
Output for ls:

Code: Select all

-rwxr-xr-x 1 root root 3275 Nov 18  2013 /etc/init.d/nagios

I'm using nagiosql to deal with configuring Nagios, nagiosQL has an option to restart nagios.
It sends the 'RESTART_PROGRAM' command to the socket, this picks it up and restarts -something- according to the logging but it does not load the updated configuration from disk.
