Alerting

Note: alerting is part of the monitoring plugin. This means that you need to activate the monitoring plugin in order to take advantage of alerting.

The main goal of the alerting in temBoard is to compare values for monitored metrics with warning or critical thresholds. It then allows users to get notified if something goes wrong on the Postgres instance.

Current status and previous alerts in dashboard

When activated, alerting can show some information on the dashboard page.

First of all, the current status for the different probes are displayed.

Also users will find the last 20 alerts. In this case, an "alert" means that a change from a status level to a higher one has been detected.

Statuses and alerts are updated every minute to match the last check.

Statuses for all monitored probes are also shown in a more detailed view in the status page.

Probe Status Over Time

By clicking on probe name, one can also access an even more detailed view for each probe. In this view, users will find:

  • the current status,
  • the thresholds values over time,
  • the values for the monitored probe over time,
  • the past alerts (ie. status change),
  • the time ranges for which the status was warning or critical or if the check was disabled.

On this page, users will also be able to enable/disable the checks and configure the thresholds.

Please beware that the thresholds are configured for each instance.
