API for Reporting High-Precision Logs

Function

This API is used to report tenant logs from a host to LTS.

The access IP address is contained in the ICAgent installation command displayed on the LTS console. The port number is 8102. You can check the Example Request to see how to add the access IP address and port number in a request.

Each log event will carry a nanosecond-level timestamp when it is reported. When you view logs on the LTS console, the log events are sorted by timestamp. For details about the constraints on log reporting, see Log Read/Write Constraints.
