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. Such a resource would be thought of as critical to the performance of the system.

Performance Monitoring available from Linux Agent 0.8.0 onwards, may be used as a form of preventive maintenance to identify any bottlenecks or critical resources on the monitored devices - so the system can be fine tuned or upgraded - before they cause increased delays and other problems.

Through Performance Monitoring, data is obtained that may prove useful when diagnosing any problems as well as allow you to build a performance profile of the system which can be used to identify abnormal load.

Performance Monitoring consists of five checks:

The Dashboard 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 N-sight RMM DashboardNorth-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 Performance Monitoring check results on a device over the last 24 hours and 8 day.

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 Dashboard 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 Dashboard 2020.01.20.
