Viewing and Filtering Events
The Events page lets you display events and alerts that have occurred within a time range you select anywhere in your clusters. From the Events page you can filter for events for services or role instances, hosts, users, commands, and much more. You can also search against the content information returned by the event.
To view events, select
.Events List
Event entries are ordered (within the time range you've selected) with
the most recent at the top. If the event generated an alert, that is indicated by a red alert icon () in the entry.
This page supports infinite scrolling: you can scroll to the end of the displayed results and the page will fetch more results and add them to the end of the list automatically.
To display event details, click the arrow () at the right side of the event
entry.
- Click the View link.

Filtering Events
You filter events by selecting a time range and adding filters.
You can use the Time Range Selector or
a duration link () to set the time range for your search. (See
Time Line for details). Note that the time it takes to perform a search will
typically increase for a longer time range, as the number of events to be searched
will be larger.
