CLS Skill
Query and analyze Tencent Cloud CLS logs.
Setup
- Install clscli (Homebrew):
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):
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 1hExamples:
- Time:
--last 1h,--last 30m; or--from/--to(Unix ms) - Multiple topics:
--topics <id1>,<id2>or multiple-t <id> - 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 | - |
