Groups

Description​

In Centreon, it is possible to group together hosts and services within groups:

Generally speaking, groups are containers in which sets of objects having a common property can be grouped together:

  • Same hardware identity (Dell, HP, IBM, etc., servers), logical identity (network equipment) or geographical identity (Europe, Asia, Africa, North America, etc.)
  • Belonging to the same application (CMS application, etc.) or to a same sector of activity (Salary management, etc.)
  • etc.

Host groups and service groups are used to group together objects by logical entities. They are used to:

  • Configure ACLs to link a set of resources to a type of profile
  • Allow viewing of availability reports by group. Generate a “Paris Agency” availability report for resources.
  • Enable viewing of the status of a set of objects by selecting a group of objects in the search filters
  • Search several performance graphs quickly by browsing the object tree structure by group and then by resource

Generally speaking, we try to group together hosts by functional level. Example: DELL and HP hosts or Linux, Windows, etc., hosts. We also try to group services by application jobs. Example: Salary management application, ERP Application, etc.

For the hosts belonging to a host group, the retention of RRD files can be defined in the host group. This definition overrides the global definition. In the event that the same host belongs to several groups, each possessing a retention definition, the highest value will be selected for the host.

Creating a host group​

Go to Configuration > Hosts > Host Groups and click Add.

  • Use the Name field to define a clear, relevant name for the host group. The name can be used in the Resource status search bar using the syntax "host_group:" to display the group's hosts.
  • Use the Alias field to better describe the host group. The alias is only visible in the host groups list.
  • Use the Group members field to add hosts to the hostgroup.
  • Use the Resource access rules section to grant members of the group access to the resources defined in the rule.
  • The Geographic coordinates field is used by the Centreon MAP module to position the resource on a map.
  • The selected Icon will be displayed in the list of host groups.
  • The Comments added here are only visible on this window.

Creating a service group​

Go to the Configuration > Services > Service Groups menu and click Add

  • The Name and Description fields describe the name and description of the service group.
  • The Linked Host Services list allows us to choose the various services that will be included in this group.
  • The Linked Host Group Services list allows us to choose the services linked to a host group that will be part of this group.
  • The Linked Service Templates list allows us to deploy a service based on this template on all hosts linked to this group.
  • The Geo coordinates field defines geographical coordinates used by the Centreon MAP module to position the resource on a map. Define "Latitude,Longitude"; for example, the set of coordinates for Paris is "48.51,2.20"
  • The Status and Comments fields allow us to enable or disable the service group and to comment on it.
