View KPIs and Alerts for an Instance or Component

Three key performance indicators (KPI) are provided for an installation: system CPU, disk space, and system memory usage. Each KPI shows a marginal threshold, which indicates that performance or stability might soon be affected, and a critical threshold, which indicates that performance or stability are probably affected. Alerts are raised when the value of a KPI changes from normal to marginal or critical, or from marginal to critical. Alerts are cleared when KPI values return to normal.

Up to three KPIs are provided for some, but not all, instances and components when they are online. Command Central retrieves KPIs regularly from the instance or component by polling. Alerts are raised when the status of an instance or component changes from online to stopped, unresponsive, failed, or unknown, or when a KPI value changes from normal to marginal or critical or from marginal to critical. Alerts are cleared when status or KPI values return to normal.

1. Go to Environments > ALL to see all instances and installations you are managing from Command Central.

2. To check alerts and KPIs for an installation, click the Installations tab and then click the installation. On the Overview tab, point to the number in the Alerts area to see messages and dates. The KPIs show the installation's usage as described below. The dashboard shows the time the information was last updated at top right.

KPI	Marginal	Critical	Notes
System CPU	80%	90%	Displays if you are using Java 7 and the system is other than HP-UX.
Disk space	80%	95%
System memory	80%	95%	On hosts running a 32-bit JRE on a 32-bit operating system with more than 2GB RAM, this KPI shows a value that is too low due to a known issue in the Java SE Runtime Environment. On Mac OS X and some Linux systems, memory often shows close to 100% utilization even under normal conditions due to the way Linux manages the memory.

3. To check alerts and KPIs for an instance or component, click the Instances tab, and then click the instance or component. On the Overview tab, point to the number in the Alerts area to see messages and dates.

Note:

Not all instances and components provide KPIs. The dashboard shows the time the information was last updated at top right.

b. On the Instances tab, open the tree for Command Central (CCE) and then click Command Central on the left.

d. Click Properties in the list of configuration types, click Monitoring Settings, and then click Edit.
