Function Overview

A log group is a group of log streams which share the same log retention settings. Up to 100 log groups can be created for a single account.

A log stream is the basic unit for reading and writing logs. You can separate different types of logs (such as operation logs and access logs) into different log streams for easier management. Sorting logs into different log streams makes it easier to find specific logs when you need them. Up to 100 log streams can be created in a log group.

ICAgent is the log collection tool of LTS. You need to install ICAgent on the hosts from which you want to collect logs.

Host groups allow you to configure host log ingestion efficiently. You can sort multiple hosts to a host group and associate the host group with log ingestion configurations. The ingestion configurations will be applied to all the hosts in the host group, saving you the trouble of configuring the hosts one by one.

• When there is a new host, simply add it to a host group and the host will automatically inherit the log ingestion configurations associated with the host group.
• You can also use host groups to modify the log collection paths for multiple hosts at a go.

ICAgent collects logs from hosts based on your specified collection rules, and packages and sends the collected log data to LTS on a log-stream basis. You can view logs on the LTS console in real time.

LTS retains the log data reported by hosts and cloud services for seven days by default. To store logs for a long time, you can transfer them to other cloud services.
