Fixed In Version: tripleo-ansible-3.3.1-17.1.20231201170809.8debef3.el9ost
Doc Type: Bug Fix
Doc Text:
Before this update, the Ceph Dashboard could not reach the Prometheus service endpoint and displayed the following error message: `404 not found.` This error occurred because the configuration of the VIP for the Prometheus service was not correct. In RHOSP 17.1.4, this problem has been resolved and the Dashboard is now able to reach the Prometheus service endpoint.

Comment 16 Manoj Katari 2023-11-28 13:14:52 UTC 
Thanks Francesco for the analysis.
I proposed a patch to deploy prometheus and alertmanager on the storage network.
Comment 17 Manoj Katari 2023-12-04 05:03:10 UTC 
how to test:

Deply ceph with dashboard enabled and then check if

- ceph dashboard prometheus config ( #ceph dashboard get-prometheus-api-host ) should match with ceph_promethus config in haproxy (/var/lib/config-data/puppet-generated/haproxy/etc/haproxy/haproxy.cfg )
- prometheus and alert_manager vip is tied to storage network
- ceph dashboard shouln't report any error saying 'unable to reach prometheus endpoint'

Hi Gareth,

The workaround mentioned in the doc text has ip details which will not be same for all environments.

I feel it is better to get rid of the workaround details in doc text (as we have the fix already) and keep it simple. wdyt ?

Manoj Katari

yeah, this fix is not part of the latest compose and the target milestone is set to z4 already.
Comment 41 Manoj Katari 2024-10-13 01:30:14 UTC 
Hi Greg,

Bug is fixed and targeted for z4, @alfrgarc can comment on verification part.

In z4 release notes, i agree that it should be a 'Bug fix' rather than a 'known issue'.

Hi Greg,

Proposed Doc text works for me.
