Once you enable the Host Map module, it will pop up in your menu in the Maps section.
When you click on it, it will show you a map:
Every host is represented by a colored marker, which indicates the overall host state.
Markers are grouped into clusters, depending on their location and the zoom level. 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.
In the upper left corner of the map there are six control elements:
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 |
| problems&host_state=1 | Show all hosts in state DOWN 1 (0 = UP, 1= DOWN) |
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.
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 can be overridden:
| 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
All config parameters above could be changed for the specific map by adding it to the URL. Use the ampersand sign for concatenation of multiple parameters.
Example: /icingaweb2/map?default_zoom=20&default_long=13.370324&default_lat=52.500859
The way in which a user-specific configuration can be stored depends on how Icinga Web 2 manages its configuration.
Add a new section named map to your users Icinga Web 2 configuration (/etc/icingaweb2/preferences/<USERNAME>/config.ini) and put in the parameters you would like to override.
You need to manually insert an entry in the users database configuration for each parameter you'd like to change:
insert into icingaweb_user_preference values ("USER", "map", "default_zoom", 5, "2018-08-23 08:52:19", "2018-08-23 08:52:19");
insert into icingaweb_user_preference values ("USER", "map", "default_lat", "29.87", "2018-08-23 08:52:19", "2018-08-23 08:52:19");
insert into icingaweb_user_preference values ("USER", "map", "default_long", "-88.90", "2018-08-23 08:52:19", "2018-08-23 08:52:19");In some environments it is desired not to cluster the markers.
The cluster function can be deactivated with the configuration option disable_cluster_at_zoom, either at a certain zoom level (e.g. disable_cluster_at_zoom=10 or completely (disable_cluster_at_zoom=1)
Set cluster_problem_count to 1 to show the number of problems in the cluster instead of the marker count.
