Performance Monitoring

Procedure

1. Choose System > Data Maintenance > Performance Monitoring.
   

   Ensure that the flash plug-in has been installed on the browser. Otherwise, the page cannot be displayed.

2. Set the usage thresholds for the server.
   1. Click in the Threshold Settings group box.
   2. The Modify Threshold page is displayed. Set the usage thresholds for the server on this page. Table 1 lists the default thresholds.

      Table 1 Default thresholds

      Parameter	Default Threshold
      CPU usage threshold	90%
      Memory usage threshold	90%
      Disk usage threshold	90%
      Database usage threshold	90%

   3. Click OK.

      Return to the Performance Monitoring page when the threshold is modified successfully.

3. Monitor the server and database performance on the Performance Monitoring group box, as shown in Table 2.

   Table 2 Monitoring the server and database performance

   Parameter	Description
   CPU	If the CPU usage has exceeded the threshold for three consecutive times, the ATIC Management center generates an alarm. When the CPU usage becomes lower than the threshold, the alarm is cleared automatically. The red line represents the threshold.
   Memory	If the memory usage has exceeded the threshold for three consecutive times, the ATIC Management center generates an alarm. When the memory usage becomes lower than the threshold, the alarm is cleared automatically. The red line represents the threshold.
   Disk	If the disk usage exceeds the threshold, the ATIC Management center generates an alarm. When the disk usage becomes lower than the threshold, the alarm is cleared automatically.
   Database	The database capacity will grow automatically with the data amount. In this case, you should check whether the used capacity is too large. Insufficient remaining disk spaces of the database will cause the improper operating of the database and ATIC Management center.
