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):

  python3 -m venv .venv . .venv/bin/activate python -m pip install -U aliyun-log-python-sdk

• Configure environment variables:

  • ALIBABA_CLOUD_ACCESS_KEY_ID
  • ALIBABA_CLOUD_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)

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

client = LogClient(
    os.environ["SLS_ENDPOINT"],
    os.environ["ALIBABA_CLOUD_ACCESS_KEY_ID"],
    os.environ["ALIBABA_CLOUD_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

python skills/observability/sls/alicloud-observability-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

python skills/observability/sls/alicloud-observability-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

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

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

Output And Evidence

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