Performance Monitoring Check

If a system resource, such as a processor core or network device, is too busy to keep up with all of its requests, it becomes a system bottleneck that could increase the delay for subsequent requests.

For preventative maintenance, use the Performance Monitoring Check to identify bottlenecks or critical resources on your monitored devices. You can use the collected Performance Monitoring data when diagnosing problems, and to help you to build a system performance profile to identify an abnormal load.

Performance Monitoring is available from Linux Agent 0.8.0 onwards.

Performance Monitoring consists of five checks:

The All Devices view displays the average and maximum values of the performance counter over the last Agent cycle and where the average exceeds the specified threshold, configurable in the Agent, an Alert is generated.

All Performance Monitoring Check failures are indicated in the All Devices viewNorth-pane under the performance_monitoring_icon icon and information on the particular check that failed is displayed in the lower pane.

The Performance Monitoring Gauge displaying the current status of the check is accessed through the clickable information line for the specific check.

The Performance and Bandwidth Monitoring History Reports show the results of Performance Monitoring or Bandwidth Monitoring checks, on an individual server, over the last 24 hours and last 8 days.

You can suppress check alerts until the Check failures exceed a configured number of consecutive failures. For more information, see Configure alert thresholds to suppress alerts.

Check configuration

The check is configured from the All Devices view or on the device. From Agent 2.0.6 Performance Monitoring Checks added during the agent installation process use the updated default threshold values introduced in console v2020.01.20.
