Assigning Agent Managers to HA partitions

Previous Next


Start by navigating to the Agent Properties dashboard, the FglAM namespace, and the FglAMAdapter properties. From there, you can edit the High Availability Host Config list-based property to assign an Agent Manager to HA Partitions and define their eligibility for becoming HA Primary hosts.

On the navigation panel, under Dashboards, navigate to Administration > Agents > Agent Properties.
4
On the Agent Properties dashboard that appears in the display area, in the Namespace/Type view, expand the FglAM node, and click the FglAMAdapter node.

Assign the Agent Manager to a desired HA Partition by editing its entry in the High Availability Host Config list. This list contains all Agent Managers that are currently connected to the Adapter, and is accessible through the High Availability Host Config property. The list also identifies the names of their respective HA Partitions, and the priorities for considering Agent Managers as potential HA Primary hosts.

Get started with editing the High Availability Host Config list-based property.
In the Properties view, under High Availability, on the right of the High Availability Host Config property, click Edit.
In the dialog box that appears, locate the Agent Manager entry that you want to add to an HA Partition, and in its HA Partition Name column, type the name of that HA Partition. Do not add an Agent Manager to this list if the client you want to assign the HA Partition is not listed here. Agent Managers that connected to this Management Server will be automatically added to this list. Manually adding Agent Mangers is not supported.

Using the JMX-Console, click FglAM:name=HAManager and invoke the diagnosticSnapshotAsString() method. The resulting output lists each of the known Agent Managers, which (if any) HA Partition they are assigned to, what deployment set they have, who is the HA Primary and what HA State they are in.

To provide eligibility for HA agent fail-over to existing agents that primarily function as remote monitors, the HA Deployment Whitelist property is included. This list-based property identifies prior cartridge deployments that were not originally marked as eligible for HA agent fail-over. In this list, each row entry contains a regular expression pattern that matches the agent package, version and agent types that are permitted to be managed in an HA Partition.
IMPORTANT: To effectively be eligible for fail-over functionality, agents must be using one of the RemoteConnection Services available in the Agent Manager Development Kit.
