Rich Features

LogListener provides one-stop log service, including log collection, storage, search, transfer, and shipping features.
LogListener parses log structures in many ways, including full text in a single line, full text in multi lines, separator, JSON, and regular expressions.
LogListener allows you to select from multiple data access methods based on your business needs. For more information, see Collection Overview.
LogListener provides multiple search syntaxes and allows you to search logs by keyword, fuzzy match, or range.

Stable and Reliable

CLS has a highly scalable distributed storage architecture. It supports horizontal scaling and automatic service scaling, and easily stores and manages massive log data.
The CLS backend storage manages and stores logs in multiple copies, ensuring data reliability.

Simple and Efficient

LogListener supports simple, GUI-based configuration. You can quickly access CLS through LogListener.
Data can be consumed immediately after being written to CLS. Query results of hundreds of millions of data records can be returned in seconds.
The service is billed by actual usage. You do not need to build or maintain a log system, preventing resource idling and waste.

Ecological Expansion

The logs of certain cloud services have already been integrated into CLS. For more information, see Accessing log sources.
Logs are shipped to Cloud Object Storage (COS), which supports long-term archive storage of logs.
Logs are shipped to CKafka, which supports real-time log consumption and facilitates further log processing and analysis.
