Alerts are an important part of any monitoring platform and Timebeat is no exception.
Default dashboards are broken down into alert categories, one of which is the Offset page.
Offset alerts provide a simple and effective alert. Configured to one graph with the visualisation restricted to the top 5 offsets (largets offset away from UTC), this is displayed as an absolute value for easy operation.
The Grafana server itself, however, is querying all of the hosts, we only visualise the top 5 so that we can maintain the performance of the front end. This alert will automatically trigger an alert when a threshold has been reached. The example above has a threshold set to 1 millisecond, this is also represented by the red line which cuts across the graph.
Although it is unlikely you ever need to visit the alerts pages as the various notification channels will make you aware they are available if you want to check the configured thresholds or modify them.
