Is your feature request related to a problem?
The default dm-worker alert rules does not monitor the validator. So if validation accidentally stopped (e.g. connection to upstream broken), there is no way to be alerted timely.
Describe the feature you'd like
Add rules involving the DM validator. I suggest including at least
dm_validator_validator_logfile_latency > 1 for 10mdm_validator_validator_error_count > 0
Describe alternatives you've considered
