CLS Skill

Query and analyze Tencent Cloud CLS logs.

Setup

1. Install clscli (Homebrew):

```bash brew tap dbwang0130/clscli brew install dbwang0130/clscli/clscli ```

1. Get credentials and region list: https://cloud.tencent.com/document/api/614/56474
2. 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" ```

1. 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.

| 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 | - |
