I would like it if the SN would send an alert via email to the SNO that an error has occurred that needs attention. The SN has an email in it's config, maybe it could send a flag to the satellite and/or SMTP relay of some kind to notify the SNO there is a serious error, or if the satellite detects a failed audit it sends and email.
I don't babysit my dashboard or SN. I look at it rarely. If there is an issue that uptimerobot doesn't detect then I won't know for days, weeks, and even months.
