We have configured some recording rules in promethues master server to get
different metric usage. Till last week those rules were working but now
some of them are not working.
If we try to execute its expression we are getting data but if we try to
execute with rule name it is showing “Empty Query Result”.
If possible, could anyone please help here.
*Not Working Rules*:
record:Disk_Usage_Node
expr:sum by(cluster, kubernetes_io_hostname)
(rate(container_fs_usage_bytes{container_name!="POD"}[5m])) /
