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?
Thanks, Erich

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

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:

Kind Regards,
