Viewing Log Files¶
You can quickly view log files of component instances or hosts to locate faults.
Precautions¶
The time information contained in a log file, if any, is automatically displayed, as shown in the red box in Figure 1. This time information is irrelevant to the time range that you set.

Viewing real-time logs
The function of real-time monitoring is disabled by default. To enable it, click Enable Real-Time Viewing. After this function is enabled, the latest written logs can be viewed.
The exception in the log records the exceptions that occur during code running. When using logs to locate faults, pay attention to the exception. For real-time log viewing, AOM automatically highlights exception keywords in logs, facilitating fault locating. Such keywords are case-sensitive. For example, exception and Exception are highlighted, but keywords such as EXCEPTION, exCeption, and EXception are not highlighted.
