Every cluster marker has a label with the number of clustered markers. + + + +By clicking on the icon, the cluster expands and the underlying host markers will be visible: + + + +To show more details about a host click on the host marker. If you want to show the host in the detail view of the `monitoring module` just click on the eye icon. + + + +### Control elements + +In the upper left corner of the map there are six control elements: + + + +## 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` | +| host_in_downtime=0&host_acknowledged=0 | Don't show acknowledged or objects in downtime | + + +## 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. + + +## Settings + +Besides the global map configuration in the module settings, it is possible to override these settings per user or per each map. + +The following parameters could be overriden: + +| Parameter | +| --- | +| min_zoom | +| max_zoom | +| max_native_zoom | +| disable_cluster_at_zoom | +| default_zoom | +| default_long | +| default_lat | +| stateType | +| cluster_problem_count | +| tile_url | + +Hierarchy: ``Module Config < User Config < Map Config`` + +### Map specific overrides + +All config parameters above could be changed for the specific map by adding it to the URL.
