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.
2. To check alerts and KPIs for an installation, click the Installations tab and then click the installation.
Note: On Mac OS X and some Linux systems, system 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.
Note: Not all instances and components provide KPIs.
4. The default polling interval is 30 seconds. To change this interval, go to Environments > ALL > Instances > CCE > Command Central Server > Configuration > Properties > Monitoring Settings and click Edit.
Note: More frequent polling will adversely affect performance.
