# SLS Log Query and Troubleshooting

Use SLS query|analysis syntax and Python SDK for log search, filtering, and analytics.

## Prerequisites

- Install SDK (virtual environment recommended to avoid PEP 668 restrictions):

```bash
python3 -m venv .venv
. .venv/bin/activate
python -m pip install -U aliyun-log-python-sdk
```
- Configure environment variables:
  - `ALIBABACLOUD_ACCESS_KEY_ID`
  - `ALIBABACLOUD_ACCESS_KEY_SECRET`
  - `SLS_ENDPOINT` (e.g. `cn-hangzhou.log.aliyuncs.com`)
  - `SLS_PROJECT`
  - `SLS_LOGSTORE`(supports a single value or comma-separated values)

## Query Composition

- Query clause: filters logs (e.g. `status:500`).
- Analysis clause: statistical aggregation, format `query|analysis`.
- Example: `* | SELECT status, count(*) AS pv GROUP BY status`

See `references/query-syntax.md` for full syntax.

## Quickstart (Python SDK)

```python
import os
import time
from aliyun.log import LogClient, GetLogsRequest

client = LogClient(
    os.environ["SLS_ENDPOINT"],
    os.environ["ALIBABACLOUD_ACCESS_KEY_ID"],
    os.environ["ALIBABACLOUD_ACCESS_KEY_SECRET"],
)

project = os.environ["SLS_PROJECT"]
logstore = os.environ["SLS_LOGSTORE"]

query = "status:500"
start_time = int(time.time()) - 15 * 60
end_time = int(time.time())

request = GetLogsRequest(project, logstore, start_time, end_time, query=query)
response = client.get_logs(request)
for log in response.get_logs():
    print(log.contents)
```

## Script quickstart

```bash
python skills/observability/sls/aliyun-sls-log-query/scripts/query_logs.py \
  --query "status:500" \
  --last-minutes 15
```

Optional args: `--project`, `--logstore`(repeatable, or comma-separated values), `--endpoint`, `--start`, `--end`, `--last-minutes`, `--limit`, `--parallel`.

## Troubleshooting script

```bash
python skills/observability/sls/aliyun-sls-log-query/scripts/troubleshoot.py \
  --group-field status \
  --last-minutes 30 \
  --limit 20
```

Optional args: `--error-query`, `--group-field`, `--limit`, `--logstore`(repeatable, or comma-separated values), `--parallel`, plus the time range args above.

## Workflow

1) Ensure Logstore indexing is enabled (queries/analysis fail without index).
2) Write query clause and append analysis clause when needed.
3) Execute with SDK/script and inspect results.
4) Control returned rows with `limit`; narrow time range when needed.

## Validation

```bash
mkdir -p output/aliyun-sls-log-query
for f in skills/observability/sls/aliyun-sls-log-query/scripts/*.py; do
  python3 -m py_compile "$f"
done
echo "py_compile_ok" > output/aliyun-sls-log-query/validate.txt
```

Pass criteria: command exits 0 and `output/aliyun-sls-log-query/validate.txt` is generated.

## Output And Evidence

- Save artifacts, command outputs, and API response summaries under `output/aliyun-sls-log-query/`.
- Include key parameters (region/resource id/time range) in evidence files for reproducibility.

cupynumeric-migration-readiness

Included

Pre-migration readiness assessor for porting NumPy to cuPyNumeric. Use BEFORE substantial porting work begins when the user asks whether code will scale on GPU, whether they should migrate to cuPyNumeric, which NumPy patterns transfer cleanly, what must be refactored before porting, or mentions pre-port assessment, scaling analysis, or refactor planning. Inspect the user's source code, look up NumPy usage, cross-reference the cuPyNumeric API support manifest, and distinguish distributed-scaling-friendly patterns from blockers such as unsupported APIs, scalar synchronization, host round-trips, Python/object-heavy control flow, shape/data-dependent branching, and in-place mutation hazards. Produce a verdict of READY, LIGHT REFACTOR, SIGNIFICANT REFACTOR, or NOT RECOMMENDED, with concrete refactor pointers.

alibabacloud-data-agent-skill

Included

Invoke Alibaba Cloud Apsara Data Agent for Analytics via CLI to perform natural language-driven data analysis on enterprise databases. Data Agent for Analytics is an intelligent data analysis agent developed by Alibaba Cloud Database team for enterprise users. It automatically completes requirement analysis, data understanding, analysis insights, and report generation based on natural language descriptions. This tool supports: discovering data resources (instances/databases/tables) managed in DMS, initiating query or deep analysis sessions, real-time progress tracking, and retrieving analysis conclusions and generated reports. Use this Skill when users need to query databases, analyze data trends, generate data reports, ask questions in natural language, or mention "Data Agent", "data analysis", "database query", "SQL analysis", "data insights".

Backend & APIsscripts

token-optimizer

Included

Reduce OpenClaw token usage and API costs through smart model routing, heartbeat optimization, budget tracking, and native 2026.2.15 features (session pruning, bootstrap size limits, cache TTL alignment). Use when token costs are high, API rate limits are being hit, or hosting multiple agents at scale. The 4 executable scripts (context_optimizer, model_router, heartbeat_optimizer, token_tracker) are local-only — no network requests, no subprocess calls, no system modifications. Reference files (PROVIDERS.md, config-patches.json) document optional multi-provider strategies that require external API keys and network access if you choose to use them. See SECURITY.md for full breakdown.
