#### Overview

In *Reports → Top 100 triggers*, you can see the triggers with the highest number of problems detected during the selected period.

Both host and trigger column entries are links that offer some useful
options:

-   for host - clicking on the host name brings up the [host menu](/manual/web_interface/menu/host_menu)
-   for trigger - clicking on the trigger name brings up links to the latest events, 
    simple graph for each trigger item, and the configuration forms of the trigger itself and each trigger item

**Using filter**

You may use the filter to display triggers by host group, host,
problem name, tags, or trigger severity. Specifying a parent host group implicitly selects all
nested host groups. For better search performance, data is searched with
macros unresolved.

The filter is located below the *Top 100 triggers* section name. It can be
opened and collapsed by clicking on the *Filter* tab on the right.

**Time period selector**

The [*Time period* selector](/manual/web_interface/time_period_selector) allows to select often required periods with one mouse click.
The *Time period* selector can be expanded and collapsed by clicking the *Time period* tab next to the filter.
