The instance is likely offline, please check and try again

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:

Code: Select all

bin/logstash -f first-pipeline.conf --config.reload.automatic

which is from the official documentation of logstash

Is elasticsearch running on all instances?

Code: Select all

service elasticsearch status

Also, you should only be starting logstash through the service command instead of what you posted in your previous command

Code: Select all

service logstash restart

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?

[scottwilkerson]

the configurations should only be edited through the UI.

[floki]

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

"The apply command hasn't started yet. The instance may not be online or is unreachable."

Is this a multi-instance cluster?

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

There should be logs here when you click apply config

Code: Select all

tail -f /usr/local/nagioslogserver/var/jobs.log

[floki]

Its a single instance Nagios log server
the only log in job.log is this:

Code: Select all

Running command run_alerts with args ' ' for job id: run_all_alerts
SUCCESS

But still can't apply config through UI

[scottwilkerson]

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:

Code: Select all

 The instance is likely offline, please check and try again.

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