# 2 Availability report

#### Overview

In *Reports → Availability report* you can see what proportion of time
each trigger has been in problem/ok state. The percentage of time for
each state is displayed.

Thus it is easy to determine the availability situation of various
elements on your system.

From the dropdown in the upper right corner you can choose the selection
mode - whether to display triggers by hosts or by triggers belonging to
a template. Then in the filter you can narrow down the selection to the
desired options and the time period.

The name of the trigger is a link to the latest events of that trigger.

Clicking on *Show* in the Graph column displays a bar graph where
availability information is displayed in bar format each bar
representing a past week of the current year.
