Scenario 2 — New Management Server features or defect fixes

A new release of Foglight typically delivers new features and defect fixes. See the Foglight Release Notes for information about new features and defect fixes. We recommend the Management Server upgrade to customers who want one or more of the features or defect fixes in a new release.

Customers who want to take advantage of new features and defect fixes can do so with a simple upgrade to the Management Server. This upgrade is expected to take 15 minutes or less. An upgrade to the server does not introduce any incompatibilities with earlier versions of other Foglight core components; therefore, with the Management Server 7.3.0 upgrade, you should not have to upgrade any other components in your environment.

Scenario 3 — Agent Manager client-side feature dependency or defect fix

A new release of the Agent Manager typically delivers new features and defect fixes. For information about new features and defect fixes, see the Foglight Agent Manager Release Notes. Customers who want to take advantage of a new feature or defect fix may consider a move to the latest Agent Manager client.

The 7.3.0 Agent Manager Adapter is updated as part of the Management Server 7.3.0 upgrade, and the new adapter is backward compatible with all earlier versions of the Agent Manager.

Generally, updating the client is not required, but it is recommended to upgrade to receive defect fixes and security updates. An Agent Manager client-side upgrade is required only in the following situations:

•
You require one or more of the new 7.3.0 Agent Manager features or defect fixes in your environment. See the Foglight Agent Manager Release Notes for details.
•
You are planning to install a cartridge that requires version 7.3.0 of the Agent Manager.

Prepare for an upgrade

Preparing for a Foglight upgrade is straightforward, but may be time-consuming. Before upgrading you should consider the following:

1
If you are upgrading the Management Server, back up your Performance Investigator (PI) repository.
2
Support recommends restarting the Foglight Agent Managers (FglAM) prior to the upgrade. This can be accomplished through Windows services or the Linux/Windows command line, or by utilizing the restart functionality in the Agent Managers panel. Doing so can help ensure that there are no issues with specific agents that could later impede the efficient shutdown of the Agent Manager in the background during cartridge upgrades.
If the Agent Manager does not shut down and restart promptly, please contact Support for assistance in reviewing the FglAM log file for potential shutdown issues caused by stuck process threads.
3
It is also recommended to stop the Foglight service in order to shut down the Foglight application. The wizard performs this task automatically, but manually shutting it down is considered a better practice.
4
Create a support bundle from your Management Server. For information on how to do this, see the “Managing Support Bundles” section in Foglight Administration and Configuration Guide.
5
If you are upgrading the Management Server, back up the file system in which Foglight is installed. For information on how to do this, see the “Backing up Foglight” section in the Foglight Administration and Configuration Help.
6
If you are upgrading the Management Server, back up your database. For information on how to do this, see the “Backing up Foglight” section in the Foglight Administration and Configuration Help.
