By default the Timebeat application holds default dashboards which if you choose to enable will be automatically deployed to your Kibana environment.
Timebeat Overview Dashboard:
This dashboard contains 5 simple yet effective visualisations so that you can quickly understand how your estate is performing.
From left to right across the top we have:
This is a count of the current reporting hosts to elastic
This is the total number of UTC sources reporting across your estate
The average offset across your estate
The maximum offset reported across your estate.
The larger data table across the bottom of the dashboard provides the above information split by host. This allows you to very easily understand which hosts are not performing to your expected level.
