Configuration Setup

The Kernel Resource Management includes several new graphs of different attributes of the Enterprise Server instance. The interval of the data in these graphs is defined by Server Manager monitors. By default, each monitor collects up to 1440 data points. In the monitor configuration, the user can specify at what interval these data points will be collected. By default, the collection interval is 60 seconds. This default value allows the collection of 24 hours worth of data points. These are two graphs used to present the data for all CPU or memory processes. These graphs can be accessed by selecting an enterprise server in Server Manager.

If a less granular data set is desired, you can increase the collection interval. If more granular data set is desired, you can lower the collection interval. However, it is not recommended to set the collection interval less than 20 seconds. The embedded Server Manager agents (in the Enterprise Server, for example) are designed to collect runtime metrics every 20 seconds. Setting the monitor collection interval to less than 20 seconds will result in duplicate (or stale) data points as well as higher CPU usage on the Enterprise Server.

Note: When the Server Manager Console (SMC) services are stopped and restarted, the collection of data for these monitors is reset. Also, any changes made to the collection interval and to the number of data points are NOT maintained and the default value of 60 seconds is used.

Note: If there are mandatory multiple EnterpriseOne instances, one may want to reduce the number of collection data points and increase the collection frequency.
