Nagios Support Forum

Good Day

Just want to ask what's wrong on my nagios log server instance. It seems that I can't apply the configurations made. It always show " The instance is likely offline, please check and try again". My current method is to configure the logstash pipeline [input, filter & output] then restart logstash. Is there another way I can load the the pipeline without restarting logstash like for example:


which is from the official documentation of logstash

Is elasticsearch running on all instances? Also, you should only be starting logstash through the service command instead of what you posted in your previous command

Good day,

Yes, my current method is to restart logstash with: systemctl restart logstash eventhough I only changed the input.conf. What im asking is if there's a way I can edit the conf files (input, filter, output) without restarting logstash?

the configurations should only be edited through the UI.

yeah but when i'm applying my configurations in the UI, I always get this message "The apply command hasn't started yet. The instance may not be online or is unreachable."

I don't know the reason, is there a log file generated when applying a config?

Thanks a lot

Is this a multi-instance cluster?

There should be logs here when you click apply config

Its a single instance Nagios log server
the only log in job.log is this: But still can't apply config through UI

Hmm, this sounds like something is stuck.

Can you go to Admin -> Command Subsystem
click "Reset All Jobs"
click OK on the dialog box

Then attempt to Apply Configuration again.

Was able to reset all the jobs but still can't apply configuration through UI still got this error in UI:

If you go to Admin -> Command Subsystem are the times updating on all of the items?
