Principle

The performance management component obtains monitoring data of ICT resources and provides intuitive monitoring data for the administrator.

Figure 3-14 shows the performance management principle.

Figure 3-14 Performance management principle

• The administrator sets a performance monitoring policy for ICT resources.
• The performance management component obtains information such as the ICT resource name and group through the device management module, listens for resource change events, and updates the monitoring policy.
• The performance management component periodically collects performance data of ICT resources based on the performance monitoring policy. If SNMP is used to collect performance data, the performance management component delivers collection requests based on the configured collection period and the device returns performance data based on the requests. If SFTP is used to collect performance data, the performance management component delivers collection tasks to the device and the device periodically reports the collected data through SFTP.
• If the collected performance data meets the threshold condition, eSight generates an alarm.
• The administrator views the performance data to learn the running status and change trend of ICT resources in a timely manner.
