##### Using filter

You can use the filter to display only the hosts you are interested in.
The filter is located above the table. It is possible to filter hosts by
name, host group, IP or DNS, interface port, tags, problem severity,
status (enabled/disabled/any); you can also select whether to display
suppressed problems and hosts that are currently in maintenance.

Notes:

-   *Name* and *Host group* fields support multiple entries.\
-   Specifying a parent host group implicitly selects all nested host
    groups.\
-   By default problems of all severities are displayed, if not
    suppressed.\
-   By default hosts in maintenance are displayed, but suppressed
    problems on these hosts are not shown.\
-   When *Severity* filter is used and *Show suppressed problems*
    checkbox is unchecked, hosts with suppressed problems of the
    specified severity will not be displayed.\
-   Hosts can be filtered by host-level tags as well as tags from all
    linked templates, including parent templates.
