Hi,
I am trying to enable prometheus on Mimic so I can use it with cephmetrics
But it fails with the following error
Any help troubleshooting this will be very appreciated
"..
Module 'prometheus' has failed: error('No socket could be created',)
.."
here is some info ( all commons ran on MON where the MGR is also installled)
ceph config set mgr/prometheus/server_addr 0.0.0.0
ceph mgr module enable dashboard
ceph mgr module ls
{
"enabled_modules": [
"balancer",
"dashboard",
"iostat",
"prometheus",
"restful",
"status"
ceph prometheus self-test
Self-test OK
excerpt from ceph-mgr-mon01.log
(Please note that dashboard plugin works fine with self-certificate after I ran
ceph dashboard create-self-signed-cert )
