New scenarios added to custom monitor 'failure notifications'

Custom monitors have a toggle to turn failure notifications on or off. When on, the monitor will send an alert to if the monitor fails to complete. This is different than the monitor triggering an anomaly alert. Instead, the job of a failure notification is to indicate that monitor was not able to check the quality of the data. When creating a new monitor, the default setting is ‘on’.

We'll now alert to cases where the “run” of the monitor never even starts. For example:

• Table not monitored: the table is not included for “monitoring” in Settings
• No connection found: the connection to the data source no longer exists
• Sampling is disabled for a value-based rule: data sampling has been turned off in your environment. This type of rule is disallowed when sampling is off.

Previously, we alerted just to cases where it started but then failed for some reason. To limit noise from repeatedly failing monitors, we’ll send no more than 1 failure notification per monitor per week.

For accounts where this will significantly increase the number of failure notifications being sent, a proactive message was delivered to Account Owners on September 25.
