AFAIK this was solved by OpenStack folks following what Vladimir suggested: keepalived + haproxy for grafana and prometheus (alertmanager has it's own gossip-based HA). Please find attached (if the mailing list permits) a document where we discussed different approaches to provide HA to the Ceph monitoring stack. And there's also an open tracker issue for this activity: https://tracker.ceph.com/issues/45546 Kind Regards, Ernesto On Wed, Mar 3, 2021 at 5:21 PM Vladimir Sigunov <vladimir.sigunov@gmail.com> wrote:
Hi, I guess you can use a load balancer like HAProxy + keepalived to make the api high available and point the dashboard to the VIP. Of course, you need to deploy more than one grafana instance.
Thanks, Vladimir

Hi,
if the host fails, to which the grafana-api-url points (in the example below ceph01.hostxyz.tld:3000), Ceph Dashboard can't Display Grafana Data:
# ceph dashboard get-grafana-api-url https://ceph01.hostxyz.tld:3000
Is it possible to automagically switch to an other host?
