Upgrade the cartridges in a federated or High Availability (HA) environment

This section provides procedures for:

•
Upgrade cartridges in a federated environment
•
Upgrade cartridges in a High Availability environment

Upgrade cartridges in a federated environment

Cartridge upgrades in a Federated environment need to be handled differently than typical cartridge upgrades. To maintain the Federated topology, you must disconnect/reconnect the queries as part of the upgrade procedure.

You must also ensure that the required cartridges are being upgraded in a Federated environment. For example, you may determine the following:

•
Federated Child # 1 requires upgrades to the Foglight for Infrastructure and Foglight for Oracle.
•
Federated Child # 2 requires upgrades to the Foglight for Infrastructure and Foglight for SQL Server.

In this example, after upgrading the two Federated Children, you need to upgrade the Foglight for Infrastructure, Foglight for Oracle, and Foglight for SQL Server on the Federation Master.

The procedure outlined below describes the required sequence of steps.

To upgrade cartridges in a Federated environment:
1
Disable the topology synchronization in the Federation Master by commenting out all child server URLs (the FederationURLs in the federation.config file).
2
Upgrade one or more cartridges on the stand-alone Management Servers (Federated Children).
 
* 
NOTE: All Federated Children that need to be upgraded must be upgraded before uncommenting the URLs in the federation.config file.
3
Upgrade same cartridges on the single, central Management Server (Federation Master).
 
4
Uncomment the child server URLs in the federation.config file.

Upgrade cartridges in a High Availability environment

When upgrading cartridges in an HA environment, if both the primary and the secondary Management Servers are running, you only need to install each cartridge you want to upgrade on the primary Management Server. The cartridges are then copied over to the secondary Management Server automatically.

The management log reports on the copying of the cartridges.

 

Appendix: Deploying an agent package using the browser interface

This section explains how to deploy an agent package using the browser interface. This method is an alternative to using the command-line interface.

In Foglight, you can use the command-line interface to deploy an agent package for an upgraded cartridge, or you can use the browser interface.

Before you can deploy an agent package on a machine, you must first install the Agent Manager and the relevant agent package on that machine.

Use the Agent Managers dashboard to deploy one agent package at a time, or to deploy the agent package to multiple hosts. You can also deploy agent packages to a single host from the Agent Status page.

 
* 
NOTE: On the Agent Managers dashboard, you can deploy an agent package to multiple hosts, as long as the hosts you select are running the same operating system.
