Tencent CLS Guide

腾讯云日志服务 (CLS) 查询与分析指南。

Rules

• String values in CQL MUST be quoted: level:"ERROR" not level:ERROR
• ALWAYS specify topic when searching — CLS requires a topic context
• SQL analysis only works when topic has "统计分析" enabled; empty result may mean Analysis: false
• Use cast(__TIMESTAMP__ as timestamp) for time operations in SQL analysis

CQL 快速参考

key:"value"              # 键值搜索（字符串必须加引号）
key:123                  # 数值搜索
value                    # 全文搜索
level:"ERROR" AND pid:1  # 逻辑与
status:>400              # 范围查询
