##### Using filter

You can use the filter to display only the maintenance periods you are
interested in. For better search performance, data is searched with
macros unresolved.

The *Filter* link is available above the list of maintenance periods. If
you click on it, a filter becomes available where you can filter
maintenance periods by host group, name and state.
