The passive checks looks to be ideal in terms of getting alerts from the host to Nagios immediately when a state changes but the overhead of managing individual files on each and every server, coupled with unique hostname/services equates to a workload that we're not prepared for. I've elected to ke...

That will be helpful, I'll run some tests and try that out.

Is there a way to pre-populate services that will be immediately associated with new unconfigured objects or is the only option to use the gear/wizard each time there is new unconfigured objects?

Ahh thanks kg2857 for help clarifying that. KWGagel It sounds when you are adding the passive the checks they are showing up in the old host object. This is happening because the old host object and the new unconfigured object have the same hostname in Nagios. One thing you can do to prevent this f...

I'd like to move to passive checks and the NCPA agent. We're still using NSClient++ on our Windows based machines with NCPA on linux. I've got one server working fully with NCPA (and NSClient++) but I'm confused on the onboarding of passive checks. It seems that each host I switch over to NCPA passi...

SNIP 1. Keeps custom scripts from being lost in libexec 2. Add directory to backup/import strategies 3. Set enhanced permissions on custom scripts 4. Home python .venv if needed for PEP --SN Thanks. I'll be sure to do that in the future. For the time being I have restored default Nagios XI behaviou...

SNIP 3. Watch the logs and see if your error message explains the issue. SNIP --SN Okay, progress. I implemented a check to test if an alert was already acknowledged. If not acknowledged then proceed with the alert otherwise ignore it. I tested this check manually and found the source of the proble...

Host settings are an important aspect. https://assets.nagios.com/downloads/nagioscore/docs/nagioscore/4/en/notifications.html Is Nagios configured to send notifications? Is the host sending notifications? If so, is it sending them to you? If so, are you receiving them? Here is a more complete pictu...

I'm not getting an email alerting me that a monitored host is critical. I thought I wasn't understanding inheritance properly so I setup a new host and used the wizard to monitor it using ping. The host isn't in any other groups, and no other templates are applied to it so whatever the host settings...

I fed all of the information in the original post to Copilot AI and worked iteratively with it to resolve the issue. Here is a summary of the steps I had to take. Here is a clean, consolidated **summary of the full sequence of steps you had to take** to successfully complete the NagiosXI upgrade on ...

The GUI update fails and recommends using manual. The manual upgrade fails too.
