CLS Skill

Query and analyze Tencent Cloud CLS logs.

Setup

Install clscli (Homebrew):

```bash

brew tap dbwang0130/clscli

brew install dbwang0130/clscli/clscli

```

Get credentials and region list: https://cloud.tencent.com/document/api/614/56474
Set environment variables (same as Tencent Cloud API common parameters):

```bash

export TENCENTCLOUD_SECRET_ID="your-secret-id"

export TENCENTCLOUD_SECRET_KEY="your-secret-key"

```

Specify region via --region (e.g. ap-guangzhou).

Usage

!IMPORTANT: If you do not know the log topic, list topics first.

List log topics

List topics in a region to determine which --region and topic ID to use for query/context.

clscli topics --region <region> [--topic-name name] [--logset-name name] [--logset-id id] [--limit 20] [--offset 0]

Examples: --output=json, --output=csv, -o topics.csv

Option	Required	Description
--------	----------	-------------
--region	yes	CLS region, e.g. ap-guangzhou
--topic-name	no	Filter by topic name (fuzzy match)
--logset-name	no	Filter by logset name (fuzzy match)
--logset-id	no	Filter by logset ID
--limit	no	Page size, default 20, max 100
--offset	no	Pagination offset, default 0
--output, -o	no	Output: json, csv, or file path

Output columns: Region, TopicId, TopicName, LogsetId, CreateTime, StorageType.

Get log by query

clscli query -q "[query condition] | [SQL statement]" --region <region> -t <TopicId> --last 1h

Examples:

Time: --last 1h, --last 30m; or --from/--to (Unix ms)
Multiple topics: --topics , or multiple -t
Auto pagination and cap: --max 5000 (paginate until 5000 logs or ListOver)
Output: --output=json, --output=csv, -o result.json (write to file)

Option	Required	Description
--------	----------	-------------
--region	yes	CLS region, e.g. ap-guangzhou
-q, --query	yes	Query condition or SQL, e.g. `level:ERROR` or `* \	select count(*) as cnt`
-t, --topic	one of -t/--topics	Single log topic ID
--topics	one of -t/--topics	Comma-separated topic IDs, max 50
--last	one of --last/--from/--to	Time range, e.g. 1h, 30m, 24h
--from, --to	one of --last/--from/--to	Start/end time (Unix ms)
--limit	no	Logs per request, default 100, max 1000
--max	no	Max total logs; when non-zero, auto-paginate until reached or ListOver
--output, -o	no	Output: json, csv, or file path
--sort	no	Sort: asc or desc, default desc

Query condition syntax

Two syntaxes are supported:

CQL (CLS Query Language): CLS-specific query syntax for logs, easy to use, recommended.
Lucene: Open-source Lucene syntax; not designed for log search, has more restrictions on special chars, case, wildcards; not recommended.

CQL syntax

Syntax	Description
--------	-------------
`key:value`	Key-value search; logs where field (key) contains value, e.g. `level:ERROR`
`value`	Full-text search; logs containing value, e.g. `ERROR`
`AND`	Logical AND, case-insensitive, e.g. `level:ERROR AND pid:1234`
`OR`	Logical OR, case-insensitive, e.g. `level:ERROR OR level:WARNING`, `level:(ERROR OR WARNING)`
`NOT`	Logical NOT, case-insensitive, e.g. `level:ERROR NOT pid:1234`, `level:ERROR AND NOT pid:1234`
`()`	Grouping for precedence, e.g. `level:(ERROR OR WARNING) AND pid:1234`. Note: AND has higher precedence than OR when no parentheses.
`" "`	Phrase search; double-quoted string, words and order must match, e.g. `name:"john Smith"`. No logical operators inside phrase.
`' '`	Phrase search; single quotes, same as `""`; use when phrase contains double quotes, e.g. `body:'user_name:"bob"'`
`*`	Wildcard; zero or more chars, e.g. `host:www.test*.com`. No prefix wildcard.
`>`, `>=`, `<`, `<=`, `=`	Range operators for numeric values, e.g. `status>400`, `status:>=400`
`\`	Escape; escaped char is literal. Escape space, `:`, `()`, `>`, `=`, `<`, `"`, `'`, `*` in values.
`key:*`	text: field exists (any value). long/double: field exists and is numeric, e.g. `response_time:*`
`key:""`	text: field exists and is empty. long/double: value is not numeric or field missing, e.g. `response_time:""`

SQL statement syntax

Syntax	Description
--------	-------------
SELECT	Select from table; data from current log topic matching query condition
AS	Alias for column (KEY)
GROUP BY	With aggregate functions, group by one or more columns (KEY)
ORDER BY	Sort result set by KEY
LIMIT	Limit rows, default 100, max 1M
WHERE	Filter raw data
HAVING	Filter after GROUP BY, before ORDER BY; WHERE filters raw data
Nested subquery	One SELECT inside another for multi-step analysis
SQL functions	Richer analysis: IP geo, time format, string split/join, JSON extract, math, distinct count, etc.

Describe log context

Retrieve log context around a given log.

clscli context <PkgId> <PkgLogId> --region <region> -t <TopicId>

Examples: --output=json, --output=csv, -o context.json (write to file)

Option	Required	Type	Description	Example
--------	----------	------	-------------	---------
--region	yes	String	CLS region	ap-guangzhou
-t, --topic	yes	String	Log topic ID	-
PkgId	yes	String	Log package ID, i.e. SearchLog Results[].PkgId	528C1318606EFEB8-1A7
PkgLogId	yes	Integer	Index within package, i.e. SearchLog Results[].PkgLogId	65536
--output, -o	no	-	Output: json, csv, or file path	-
