Monitor a metric

You monitor metrics to be aware of data quality issues that the metrics uncover.

❗️

The procedures on this page require the Workspace Editor role, unless otherwise noted at the top of the procedure.

  • A metric periodically calculates values from a data asset and aggregates those results into a single value.
  • A monitor provides a mechanism for generation of incidents when a metric value deviates from desired bounds.
  • A monitor is associated with a single metric and specifies a range of metric values that are “out of bounds”.
  • As time goes on, if a monitor is attached to a metric, the monitor will generate incidents when the metric value is found to be out of bounds.
  • A monitor may be either a manual monitor, in which case the bounds are specified explicitly by the data analyst, or an anomaly monitor, in which case the bounds are generated by looking at the historical norms for the metric.

Create a monitor

  1. On the metric's chart in Explorer, select Monitors -> + Add monitor.
  2. If the Add Monitor modal includes Threshold/Anomaly Detection buttons, choose Threshold to manually provide upper and lower bounds for the value, or choose Anomaly Detection to have the monitor observe the metric for a while and automatically decide what's abnormal.
  3. If you have an alerting channel ready and want incidents to generate alerts there, enter it under Select the channels to send notifications. You can also manage alerting channels later, after the monitor is working.
  4. Optionally, move the Mute toggle to the right to prevent the monitor from generating alerts.
  5. Click OK to save the new monitor and begin any training. After you finish setting up, the monitor detects when its metric's value is out of bounds and logs variations as incidents. A monitor can bundle consecutive variations as one incident or record them as separate incidents.

Pause/Resume a monitor

On the metric's chart in Explorer, do one of the following:

  • Select Monitors → Pause monitor → name-of-the-monitor .
  • Select Monitors → Resume monitor → name-of-the-monitor .

Manage a monitor's alerting channels

  1. On the metric's chart in Explorer, select Monitors → Manage alerting channels → name-of-the-monitor .
  2. In the Notification Channels modal, click the box to select one or more existing alerting channels. As needed, adjust the Mute toggle. Note that if the monitor is muted, all alerting channels will stop receiving alerts for incidents.
