Ivanti Automation Dispatchers (Discover)

Use the Task Discover Ivanti Automation Dispatchers to check which Dispatchers are available to Agents.

This allows you to query which Dispatchers are available to an Agent with the current Agent settings, but also to query which Dispatchers are available to an Agent if you were to change the Agent settings. This allows you to test new settings before implementing them.

Dispatcher Detection settings

Dispatcher discovery

Specifies the Agents' search method for Dispatchers.

Dispatcher locations

Specifies where Agents should search for Dispatchers.

Dispatcher recovery

Specifies which action Agents should take if no Dispatchers can be contacted:

If you select Revert to cached list of all known Dispatchers, any other Dispatchers known to the Agent may be used if no Dispatcher can be contacted. You can prevent this by selecting Retry discovery.

Configuration

The Dispatcher discovery and Dispatcher locations settings are closely related. Use their options to create a combination that specifies how and where an Agent should search for a Dispatcher.

  • Dispatcher discovery. The default is to use global Dispatcher address list (from Setup >Global settings). If necessary, clear that option and modify the Dispatcher address list manually. Click Add in the Dispatcher discovery window and specify the Dispatcher addresses. Use the Delete button to remove Dispatcher addresses.
  • Dispatcher locations, Retrieve Complete Dispatcher Address List After Discovery. Agents search only for the Dispatchers that you specified in the Dispatcher address list. Once the Agent is connected to one of the Dispatchers specified in the Dispatcher List, it will then receive the list of all online Dispatchers available in the environment. This list is what the Console is presenting in the Topology > Dispatchers node. The Agent will then try to randomly connect to one of the Dispatchers from the retrieved complete Dispatcher address list.
  • Dispatcher locations, Only Use Discovered Dispatchers. Agents will not receive the complete Dispatcher address list and will try to connect to one of the Dispatchers specified in the Dispatcher address list. Specify at least one Dispatcher in the list.
  • Ivanti Automation 2019.0 removes the dispatcher autodetect functionality that was present in previous versions. It is considered obsolete and not secure.
  • When you change any of the Dispatcher detection settings, either at global level or at Agent level, the Agent will store the previous Dispatcher detection settings as the Last Known Good Configuration(LKGC). These are the settings with which it is certainly possible to connect to a Dispatcher.
    • The Agent will only revert to the LKGC if it is not possible to connect to any Dispatcher immediately after changing the Dispatcher detection settings.
    • The Agent will not revert to the LKGC if it is not possible to connect to any Dispatcher at a later stage (for example, because the Dispatchers get offline).
    • When an Agent has reverted to the LKGC, it will retry the new settings every 5 minutes. The Agent will keep trying with these settings until it can connect to a Dispatcher or until it receives new Dispatcher detection settings.
