Nagios XI 5.5.7 issues with some alerts

[emartine]

I just had a user that told me they didn't receive notifications for their service being down. I checked and sure enough I saw 3/3 issues but it showed only a soft state. I tested this out by submitting 3/3 passive tests and sure enough it didn't go critical. This one host has the same issue on all of its services. I recreated the service that the user was having a problem with and tested out 3/3 passive tests and it went hard, critical and notifications went out. Other servers seem to be working fine. What could be causing this behavior?

Hello, @emartine. There is a bug in the latest Core that causes some services to get stuck in a soft state. So instead of going HARD the service continues to be in a 3/3 SOFT state.

Some users reported that after the deleted and recreated the service notifications started working as they should.

Our developers are already working on a bug fix and it can be tracked on the github:
https://github.com/NagiosEnterprises/na ... issues/576

As a temporary workaround this problem we recommend downgrading the Nagios Core to 4.2.4.

It took a while to put in a change control just to upgrade it to this version. Is there an estimate of when a fix will be implemented? This is occurring on our production system. I have deactivated the host and services and reactivated them which seems to have worked but might be a temporary fix. Is this an intermittent issue that occurs with supression of alerts???

Hi @emartine,

Sorry about the troubles you are experiencing after upgrading, I’ve discussed this issue with the development team at Nagios and we are currently working on it.

For now, as @npolovenko suggested, I would recommend downgrading to Nagios Core 4.2.4 as I don’t have an exact time estimate and Nagios Core upgrades are subject to a longer testing period before they are released.

If you decide to downgrade to Nagios 4.2.4, please let us know if you need any assistance or have any other questions.

Thank you.

That is pretty bad. We upgraded Nagios to fix the security issues that our security team was concerned about. If I rolled back our security team will have a field day with me. This would be problematic.

Hi @emartine,

We are working on this issue right now, and I understand why downgrading to Nagios 4.2.4 may not be feasible for you.

In meantime, if you have another server environment for testing, I do have a patch from development that is available to test and should resolve the issue.

Thank you for your patience, and I will update you as soon as I have more information.

Hi @emartine,

We're planning to release new version Nagios core with updates to resolve this issue next week.

In the coming days, I can provide a download link and instructions for updating your server. Please let me know if you have any questions.
