The monitoring module provides list views for hosts and services. These lists only provide the most common columns to reduce the backend query load.
If you want to add more columns to the list view e.g. in order to use
the URL in your dashboards or as external iframe integration, you need
the addColumns
URL parameter.
Example for adding the host address
attribute in a host
list:
http://localhost/icingaweb2/monitoring/list/hosts?addColumns=host_address
Example for multiple columns as comma separated parameter string.
This includes a reference to the Icinga 2 host object custom attribute
os
using _host_
as custom variable
identifier.
http://localhost/icingaweb2/monitoring/list/services?addColumns=host_address,_host_os
