【Product�? OperationCenter 【Version�? 3.0.9 and earlier versions 【Fault Type�? Interconnection fault 【Symptom�? The system interconnection is successful, but no performance data is displayed on OperationCenter. 【Fault Locating�? Possible cause 1: The time of the interconnected system is different from that of OperationCenter. Step 1 Log in to the OperationCenter server as user appuser, run the sudo su-root command, enter the root password, and run the date command to view the current system time. Step 2 Log in to the interconnected system. Check whether the current system time is the same as the system time of the OperationCenter server. The time difference must be within 30 minutes. Step 3 Wait for two hours after the first interconnection and then check whether there is any performance data on OperationCenter. Step 4 View the time and time zone of the current browser. Possible cause 2: The interconnected system has no performance data. Check whether the interconnected system contains any performance data. 【Troubleshooting�? If time inconsistency occurs, change the time of the OperationCenter system to that of the interconnected system and then view the performance date on OperationCenter. If the interconnected system is the same as that of OperationCenter, but no performance data is displayed on OperationCenter, contact Huawei technical support. If the interconnected system has no performance data, generate performance data and then view the data on OperationCenter. If the interconnected system has performance data, but no performance data is displayed on OperationCenter, contact Huawei technical support. ----End
