description: Fetch and diagnose vLLM Buildkite CI failure logs. Use when investigating failing CI jobs on a PR or build, when the user pastes a buildkite.com URL, or asks to fetch/diagnose CI logs.

# Diagnosing vLLM Buildkite CI Failures
Buildkite logs are public; no login needed.
`.buildkite/scripts/ci-fetch-log.sh` saves each log as `ci-<build>-<job-name>.log`, stripped of timestamps and ANSI codes. Existing files are kept; set `CI_FETCH_LOG_FORCE=1` to refetch.
## Fetching logs
```bash
# All failed jobs in a PR's latest build (current branch's PR if omitted):
.buildkite/scripts/ci-fetch-log.sh --pr <PR>
# All failed jobs in a build (--soft also includes soft-failed jobs;
# --all fetches every finished job):
.buildkite/scripts/ci-fetch-log.sh "https://buildkite.com/vllm/ci/builds/<N>"
# One job — `gh pr checks` URLs (#<job_uuid>) and web UI URLs (?sid=) both
# work; pass "-" as a second argument to stream to stdout:
.buildkite/scripts/ci-fetch-log.sh "https://buildkite.com/vllm/ci/builds/<N>#<job_uuid>"
```
To clean an already-downloaded log with `.buildkite/scripts/ci-clean-log.sh`:
```bash
./ci-clean-log.sh ci.log
```
