Host basic information​

  • The Name field defines the host name that will be used by the Monitoring Engine. The following characters are not authorized: ~!$%^&|'"<>?,()=*{} and spaces.
  • The Alias field shows the alias of the host.
  • The Address field defines IP address or DNS name of the host. The Resolve button enables us to resolve the domain name by questioning the DNS server configured on the central server.

  • The Monitoring server field indicates which poller server is charged with monitoring this host.
  • The Timezone field indicates the timezone location of the monitored hosts.
  • The Templates field enables us to associated one or more templates of hosts with this object.

In case of conflicts of settings present on multiple templates, the host template above overwrites the identical properties defined in host templates below.

This button enables us to change the order of host templates image This button serves to delete the host template image

  • If the Create Services linked to the Template too field is defined as Yes, Centreon automatically generates the services based their self on the service templates linked to the host templates defined above.

Host check options​

  • The Check Command field indicates the command use to check the availability of the host.

  • The Args field defines the arguments given to the check command (each argument starts with a ”!”).

  • Custom macros:

    • The Name and Value field enable us to define the name and value of the macro.
    • The Password box enables the value of the macro to be hidden.

    To reinitialize to the default value (defined in template) click on image

    To view the description of the macro, click on image

    To delete the macro, click on image

Scheduling options​

  • The Check Period field defines the time period during which the scheduler checks the status of the object.
  • The Max Check Attempts field defines the number of checks to be performed before confirming the status of the host: when the status is confirmed the notification process is triggered.
  • The Normal Check Interval is expressed in minutes. It defined the interval between checks when the host status is OK.
  • The Retry Check Interval is expressed in minutes. It defined the check interval of the Not-OK status of the host.
  • The Active Checks Enabled and Passive Checks Enabled fields enable / disable the active and passive checks.

Notification tab​

  • The Notification Enabled field enables us to enable or disable the notifications concerning the object.

  • The list of Linked contacts indicates the contacts which will receive the notifications.

  • The list of Linked contacts Groups indicates the groups of contacts which will receive the notifications.

    If, on page Administration > Parameters > Centreon UI, the Vertical inheritance only option is enabled, two extra checkboxes appear:

    • If the Contact additive inheritance box is checked, Centreon does not overwrite the configuration of the parent host template but adds the contacts in addition to the contacts defined in the parent template.
    • If the Contact group additive inheritance box is checked, Centreon does not overwrite the configuration of the parent host template but adds the contact groups in addition to the contact groups defined in the parent template.

  • The Notification Options define the statuses for which a notification will be sent.

  • The Notification Interval is expressed in minutes. It indicates the time between sending each notifications when the status is Not-OK. If the value is defined as 0 the scheduler sends a single notification per status change.

  • The Notification Period field indicates the time period during which the notifications will be enabled.

  • The First notification delay is expressed in minutes. It refers to the time delay to be respected before sending the first notification when a Not-OK status is validated.

  • The Recovery notification delay is the time that must pass before a recovery notification is sent (when the host goes back to an UP state).

Relations tab​

  • The Host Groups list defined the host groups to which the host belongs.
  • The Host Categories list defined the categories to which the host belongs.

  • The Check Freshness field allows us to enable or disable the result freshness check.
  • The Freshness Threshold is expressed in seconds. if during this period no host status change request (passive command) is received the active check command is executed.
  • The Flap Detection Enabled field allows us to enable or disable the detection flapping in the statuses (status value changing too often on a given period).
  • The Low Flap Threshold and High Flap Threshold fields define the high and low thresholds for the detection of flapping in percentage of status change.
  • The Retain Status Information and Retain Non Status Information fields indicate if the information concerning the status is saved after every time the check command is repeated.
  • The Stalking Options field defined the options to be recorded if retention is enabled.
