alert rule can use defined value?

[fumanne]

My one metrics looks like this:

ceph_osd_up{ceph_daemon="osd.0",cluster="aaaaa",endpoint="http-metrics",instance="172.20.198.250:9283",job="rook-ceph-mgr",namespace="rook",pod="rook-ceph-mgr0-79f59b566-2lqvd",service="rook-ceph-mgr"}

ceph_osd_up{ceph_daemon="osd.1",endpoint="http-metrics",instance="172.20.164.17:9283",job="rook-ceph-mgr",namespace="rook",pod="rook-ceph-mgr0-79f59b566-snzx5",service="rook-ceph-mgr"}

first metrics have cluster label, second have not cluster label
When I configure alert rule. I want to show cluster in every metrics (but the second rule have not cluster label).
Whether alert rule can support the default label value which I can defined (if metrics have no this label).
I mean alert rule looks like this:
description: {{ $labels.ceph_daemon }} In {{ $labels.cluster | default bbbb }} is Down'

You can fix this in your query with label_replace().

label_replace(ceph_osd_up, "cluster", "bbbb", "cluster", "")
