    displays health monitors status for pools and servers.

The health status displayed for a DTC server includes health monitors assigned through the pool as well as individual health monitors per IP address or domain name of the server, if assigned. For example, monitor_name(monitor_type) for a pool monitor, and IP_address_or_FQDN(monitor_type) for an individual server monitor.

  • Ratio: Dynamic: In DTC pools and servers visualization, this displays traffic distribution across members and servers with the Ratio: Dynamic load balancing method applied.

Status and Meaning


Running: The object is fully available and operational.


Warning: The object has a warning message. You can check the syslog for any messages.


Error: The object has an error. You can check the syslog for any messages.


Disabled: The object is disabled due to a configuration setting. This may include a few different reasons, such as the "Disable" flag being set, the DNS service not running on the selected member, a zone not assigned to an LBDN, or the LBDN not associated with a zone for the selected DTC member.


Unknown: The DTC object status has not yet been determined.


Unlicensed: The object does not have a DNS Traffic Control license.

...

  • Server: Aggregated status from all pool monitoring across all DTC Grid members.
  • Pool: Aggregated status for all its servers across all DTC Grid members.
  • LBDN: Aggregated status for all its pools across all DTC Grid members.

For the visualization panel, the status is calculated as follows:

  • Server: Status from selected pool monitoring for selected DTC Grid member.
  • Pool: Aggregated status for all its servers for selected DTC Grid member.
  • LBDN: Aggregated status for all its pools for selected DTC Grid member.

For information about the configurable properties of DTC objects, see Managing DNS Traffic Control Objects on page 1062.

3. If necessary, configure the topology rulesets, topology database, and DTC health monitors used in your DTC structure. For information, see Defining Topology Rulesets, Importing a Topology Database, and Using DNS Traffic Control Health Monitors correspondingly.

...

Once all objects are enabled and all necessary service restarts are performed, the whole DTC structure starts working.
