Enabling metrics collection for Sametime Gateway
Enable the IBM® WebSphere® PMI (Performance Monitoring Infrastructure) tool and begin collecting performance metrics on WebSphere Application Server.
Before you begin
Before enabling metrics collection, make sure that the Sametime® Gateway server is running. In a cluster, the deployment manager and nodes agents must be running.
About this task
The PMI tool collects and displays general WebSphere Application Server performance metrics on servers hosting Sametime Gateway. You can enable metrics collection for Sametime Gateway by creating a custom property that specifies the level of metrics that you want to collect. If you do not specify a custom level, the ServerHealth level is used by default. There are three levels of metrics collection:
- Server Health
This lightweight metrics set is guaranteed not to cause any server performance degradation. When you enable metrics collection, this level is used by default.
- Problem Determination
This extended set of application metrics can be enabled to assist in a problem determination scenario. This level should only be turned on if instructed by IBM Support. All metrics that are part of the Server Health set are also included of the Problem Determination set.
- Off
Metrics collection is disabled.
Procedure
Results
Metrics collection is automatically enabled (or disabled) and set to the specified level after the server or cluster has started.
