Hi Cameron, I'd recommend using the slack channel and posting more info about the kind of errors you are getting. Regards, Redo. On Fri, Jun 19, 2026 at 12:47 PM Cameron Ditchfield via ceph-users < ceph-users@ceph.io> wrote:
Hi !
Has anyone running Tentacle successfully got the management gateway working with a non-cephadm-root issued certificate?
I'm struggling to get it working with Prometheus & Alertmanager when using a cert not issued by the cephadm-root CA. I have a Tentacle cluster v20.2.1 that has the management gateway deployed across three nodes with a keepalived ingress and virtual IP. I've updated the dashboard to point to the DNS hostname for the VIP for alertmanager and prometheus.
I can access the dashboard via the hostname, as expected, but there are no metrics on the overview page and there's a cannot verify SSL cert error for both alertmanager and prometheus. The CA that issued the gateway cert is trusted by all nodes in the cluster.
Thanks, Cameron
