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 material 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 per group. Generate a “Paris Agency” availability report for resources.
  • Enable viewing the status of a set of objects by selecting in the search filters of a group of objects
  • 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. E.g.: DELL and HP hosts or Linux, Windows, etc., hosts. We also try to group services by application jobs. E.g.: 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 the Configuration > Hosts > Host Groups (simplified) menu and click on Add

  • The Name and Alias defines the name and the alias of the host group.
  • The Geographic coordinates field defines geographical coordinates used by the Centreon MAP module to position the resource on a map
  • The Members list allows us to add hosts in the hostgroup.

Creating a service group

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

  • The Name and Description fields describes the name and the 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 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 for Paris coordinates set "48.51,2.20"
  • The Status and Comments fields allow to enable or disable the service group and to make comment on it.
