+# Filter Map Object
+
+The map module allows you to filter objects by using the Icinga Web 2 filter syntax.
+
+## Special Filters
+
+### objectType
+
+This filter could be used to show only hosts, services or both object types.
+
+**Example URL:** ``/icingaweb2/map?objectType=host``
+
+**Allows values:** 
+
+| Values | Description |
+| ------ | ----------- |
+| ``all`` | Show both (hosts & services) on the map |
+| ``host`` | Show only hosts on the map |
+| ``service`` | Show only services on the map |
+
+### problems
+
+If you only want to see hosts or services with states distinct from ``OK``, use this filter.
+
+**Example URL:** ``/icingaweb2/map?problems``
+
+
+## Filtering host objects
+
+The usual icingaweb2 filter syntax can be used to filter the set of hosts being displayed. Filters have to be appended to the url (eg. `?host=web*`)
+
+**Filter examples:**
+
+| Filter expression | Description |
+| ----------------------------------------------------- | ------------ |
+| hostgroup_name=customer1&_host_environment=production | Show all hosts of hostgroup `customer1` of where the custom variable environment is equal to `production` |
+| _host_customer=(max-corp\|icinga)                     | Show all hosts where the custom variable `customer` is set to `max-corp` or `icinga` |
+
+### Change default parameters
+
+It's possible to change the parameters ``default_zoom``, ``default_long`` and ``default_lat`` for a map by adding the parameters to the url:
+
+```map?default_zoom=20&default_long=13.370324&default_lat=52.500859```
+
+## Dashboard integration
+
+To add a map widget to a dashboard (or a new one) click on the `Add to dashboard` button as shown above. Any filters which are applied to the current view, are also stored in the dashlet.
