Unified Health Monitoring not working in FMC

petter.miller — Wed, 08 Dec 2021 22:10:16 GMT

Hello experts!

The new unified health monitoring page in Firepower Management Center does not load and reverts back to the legacy health monitoring page. I'm running 7.1 at the moment but had the same issue on 7.0 and 6.7. I have 1 FPR1010 added to FMC.

Has anyone encountered this issue and managed to resolve it?

Kind regards,

Petter

Just to confirm: You are running 7.1 on your FMC and 1010s? Can you also post a screenshot of what you are seeing?

Yes 7.1 on both FMC and 1010.

Decided to take a different approach to resolve the issue. After restoring a backup (7.1) to a clean FMC install the issue will reappear. The error must somehow be included in the backup.

Decided to do this instead - which resolved the issue.

A clean install of FMC
Exported (no backup) all possible policys from the old faulty FMC
Deleted the FPR1010 from the old FMC
Imported the policys into the new FMC
Added the FPR1010 to the new FMC
Manually restored the settings that didn't get imported.

Hi Petter,

Take into account that this was documented and it also has a workaround:

https://bst.cloudapps.cisco.com/bugsearch/bug/CSCwa40645

Symptom: When opening the FMC Health Monitor UI, the old version of the page is displayed.

Conditions: - Cisco Firepower Management Center for VMware - Version 7.0.1

Workaround: Go to System > Configuration > REST API Preferences ; and check the "Enable REST API" checkbox.

Further Problem Description: On FMCv version 7.0.1, when clicking on System > Health > Monitor , the browser opens the URL /ui/device-monitoring/health, but before it loads, the browser is redirected to the URL /health/healthmon.cgi and displays the old version of the Health Monitor UI.

BR,

Octavian
