alerting is part of the
monitoring plugin. This means that you need
to activate the
monitoring plugin in order to take advantage of
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¶
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.
Current Probes Status Detailed¶
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
criticalor 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.
Every UI component detailed above this section are refreshed every minute to match the latest checks.
