Log Group

A log group is the basic unit for LTS to manage logs. It comprises log streams and categorizes them, but does not store any log data itself.

For more information, see Managing Log Groups.

Log Stream

A log stream is the basic unit for reading and writing logs. Collected logs of different types are classified and stored in different log streams for easier log management. If there are a large number of logs, you can create multiple log streams and name them for quick log search.

For more information, see Managing Log Streams.

Host

A host is a physical or virtual device that computes independently and has unique network identifiers. It runs software and serves as the fundamental component for network communication. For LTS, hosts are classified into intra-region hosts and extra-region hosts.

• An intra-region host is in the same region as your LTS console, for example, a Huawei Cloud ECS.

  For more information, see Installing ICAgent (Intra-Region Hosts).

• An extra-region host refers to a host located outside the current Huawei Cloud region or a non-Huawei Cloud host. This category includes hosts in self-built Internet Data Centers (IDCs), those provided by third parties, and those in other Huawei Cloud regions.

  For more information, see Installing ICAgent (Extra-Region Hosts).

Host Group

A host group organizes multiple hosts. By adding hosts to a group and associating that group with log ingestion configurations, you can easily apply the same collection settings to all hosts within the group. This simplifies both host management and log collection.

For more information, see Managing Host Groups.

Log Ingestion

LTS enables real-time log ingestion through various modes, such as ICAgent, APIs, SDKs, and direct ingestion from cloud services. On the LTS console, you can perform a full range of operations on the ingested logs, including searching and analyzing logs, displaying log statistics using charts or dashboards, and configuring alarm reporting and log transfer.

For more information, see Log Ingestion.

ICAgent Structuring Parsing Configuration

ICAgent structuring parsing is performed on the collection side and supports combined plug-ins for parsing. You can set multiple collection configurations with different structuring parsing rules for a single log stream.

For more information, see Configuring ICAgent Structuring Parsing.

Cloud Structuring Parsing Configuration

Leveraging the computing power of LTS, cloud structuring parsing structures logs in log streams using various log extraction methods. In the future, it will incur log processing traffic fees based on the log volume.

For more information, see Setting Cloud Structuring Parsing.

Log Visualization

LTS can analyze structured logs with SQL query syntax and display analysis results in various charts, catering to visualization needs of different O&M and operations analysis scenarios.

With more than 40 out-of-the-box dashboard templates and preset sample data that are easy to use and configure, LTS lowers the usage threshold and reduces repetitive development work. Cloud service logs ingested to LTS can be directly displayed in dashboard templates. This helps enterprises realize digital operations based on log data and facilitates digital transformation.

For more information, see Log Visualization.

Log Alarm

LTS allows you to create log alarm rules of the keyword, search analysis, and SQL statistics types to trigger alarms. You can then view alarm details in the alarm list to monitor log data in real time. You can also configure alarm notification rules to send alarms via channels like SMS message or email, ensuring you are notified and respond to alarms promptly.

For more information, see Log Alarms.

Log Transfer

Logs reported to LTS from hosts and cloud services are retained for the retention period you specify. Once this period ends, LTS automatically deletes the logs. For long-term storage (log persistence), LTS provides the transfer function to transfer logs to other cloud services.

The log transfer function only replicates existing logs and does not delete the originals. Transferred logs are not affected by the automatic deletion of retained logs in LTS once the retention period is over.

For more information, see Log Transfer.
