D.5.5 Time lag on the performance graph

Phenomenon

The performance data is not displayed at time zone that the I/O has executed, and it is displayed at past time zone.

Action

This phenomenon occurs by a time lag between the administrative server and the managed device. Synchronize the time between the administrative server and the managed device by executing the following action.

1. Stop the performance management of the target device by executing "7.2.10 Instruction for stopping performance management".

2. Synchronize the time between the administrative server and the target device.

3. Start the performance management of the target device by executing "7.2.2 Instruction for performance management".

Point

This phenomenon may occur even if time in the device is temporarily synchronized by the above action. To prevent the occurring time lag again, it is recommended to do the NTP setting and synchronize the time between the administrative server and managed devices.
