Upgrade the Foglight Agent Manager

This section describes the procedure for upgrading the Foglight Agent Manager (FglAM). The latest version of the Agent Manager is 5.8.5.8.

Remote updates of the Agent Manager are deployed from the Management Server. Local access to Agent Manager clients is typically not required to perform an upgrade.

For more details, see these topics:

Upgrade the Agent Manager

1
Navigate to Dashboards > Administration > Cartridges > Cartridge Inventory.
3
In the Install Cartridge dialog box, click Browse to locate the .car file you require to upgrade the Agent Manager.
4
Ensure that the Enable on Install box is selected.
5
Click Install Cartridge to install the latest version of the Agent Manager upgrade .car file on the Management Server. Do not delete any of the old .car files.
A progress message appears and, after a few moments, the Operation(s) Complete message box appears, indicating success.
6
Click OK to close the message box.
7
On the navigation panel, click Dashboards > Administration > Agents > Agent Managers.
The Deploy Agent Package dialog box opens.
After the “Agent deployment was successful.” message and a green checkmark appear in the Deploying Agent Package box (that is, after the Agent Managers have restarted), you must wait a few additional minutes for the version number of the affected Agent Manager to be updated.

Upgrade concentrators

When the Agent Manager is deployed using concentrators, all of the concentrators need to be upgraded before the downstream clients are upgraded. Otherwise, when a downstream client is restarted, it sends its upstream concentrator messages in an unknown format, making communication between the two impossible.

Consequently, the Upgrade button on the Agent Hosts dashboard is disabled for downstream clients until all of the upstream concentrators have been upgraded to the latest version.

See the Foglight Agent Manager Installation Guide for more information about running Agent Managers as concentrators.
