| ### Problem | |
| - There is no abnormal log in Agent log and Collector log. | |
| - The traces can be seen, but no other information is available in UI. | |
| ### Reason | |
| The operating system where the monitored system is located is not set as the current time zone, causing statistics collection time points to deviate. | |
| ### Resolution | |
| Make sure the time is synchronized between collector servers and monitored application servers. |
