Problem：

• There is no abnormal log in Agent log and Collector log,
• The traces show, but no other info 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.

Resolve： Make sure the time is sync in collector servers and monitored application servers.
