Add GitHub API rate limit observability via JSONL artifact logging and OTLP span enrichment by Copilot · Pull Request #24694 · github/gh-aw

Copilot · 2026-04-05T09:05:44Z

GitHub API rate limits are a silent failure mode in busy repos with no post-run visibility. This adds a github_rate_limits.jsonl log file written during workflow execution and uploaded as part of the job artifact, with rate-limit data also surfaced directly in OTLP conclusion spans.

New helper: `github_rate_limit_logger.cjs`

Three usage patterns:

Per-call logging (inspect response headers):

logRateLimitFromResponse(response, "issues.listComments");

Point-in-time snapshot (calls the rate limit API):

await fetchAndLogRateLimit(github, "startup");

Automatic wrapping (zero call-site changes required):

const gh = createRateLimitAwareGithub(github);
// Every gh.rest.*.*() call now auto-logs rate limits
await gh.rest.issues.get({ owner, repo, issue_number: 1 });

Each entry written to /tmp/gh-aw/github_rate_limits.jsonl:

{"timestamp":"2026-04-05T08:30:00.000Z","source":"response_headers","operation":"issues.listComments","resource":"core","limit":5000,"remaining":4823,"used":177,"reset":"2026-04-05T09:00:00.000Z"}

Integration via `setup_globals.cjs`

The github object is automatically wrapped with createRateLimitAwareGithub inside setupGlobals, so every script that uses global.github gets rate-limit logging for all github.rest.*.*() calls without any per-file changes.

check_rate_limit.cjs — retains a fetchAndLogRateLimit call at startup for a full multi-resource snapshot via the rate-limit API

OTLP span enrichment

sendJobConclusionSpan in send_otlp_span.cjs now reads the last entry from github_rate_limits.jsonl and includes the following attributes in the OTLP conclusion span payload:

gh-aw.github.rate_limit.remaining
gh-aw.github.rate_limit.limit
gh-aw.github.rate_limit.used
gh-aw.github.rate_limit.resource

This makes rate-limit headroom at job conclusion time visible directly in any connected OTLP collector or tracing UI without requiring separate artifact inspection.

Artifact upload

github_rate_limits.jsonl added to both the activation and agent artifact upload paths in the Go compiler (compiler_activation_job.go, compiler_yaml_main_job.go). Uses if-no-files-found: ignore so the upload step is a no-op when no API calls were made.

@copilot instrument github object in setupGlobals script. Avoid double wrapping.

Wrap the github object with createRateLimitAwareGithub in setupGlobals so every github.rest.*.*() call across all scripts automatically logs rate limits. Remove the now-redundant logRateLimitFromResponse calls from check_rate_limit.cjs and github_api_helpers.cjs.

@copilot instrument github object in setupGlobals script. Avoid double wrapping.

Done in commit 3810637. setupGlobals now wraps the github object with createRateLimitAwareGithub before assigning it to global.github, so every github.rest.*.*() call across all scripts automatically logs rate-limit headers without any per-file instrumentation. The redundant logRateLimitFromResponse calls have been removed from check_rate_limit.cjs and github_api_helpers.cjs.

Smoke test review on PR #24694: The rate-limit observability additions look solid. The new github_rate_limit_logger.cjs file is well-structured with three usage patterns (response headers, point-in-time snapshot, and automatic wrapping). Artifact upload uses if-no-files-found: ignore which is correct. Minor: JSDoc could cross-reference the constants file.

Nice addition! The new github_rate_limit_logger.cjs provides three flexible usage patterns for rate-limit observability. Consider adding a note in the JSDoc about the file path being controlled by GITHUB_RATE_LIMITS_JSONL_PATH from constants.cjs for discoverability.

Good addition — including github_rate_limits.jsonl in the activation artifact ensures rate limit data is captured for the setup phase. Consider verifying the file is always present before upload to avoid silent failures.

Including the rate limits JSONL in the agent artifact upload is consistent with the activation step. The if-no-files-found: ignore on the surrounding block means this won't fail if not generated — good defensive practice.

@copilot the otel helper that create the span message should read the last message in the rate limiting file and include the rate limiting level in the otel payload

Done in commit bb7b5d7. sendJobConclusionSpan in send_otlp_span.cjs now calls readLastRateLimitEntry() (which reads the last line of github_rate_limits.jsonl) and adds the following attributes to the OTLP span payload when the file is present:

gh-aw.github.rate_limit.remaining
gh-aw.github.rate_limit.limit
gh-aw.github.rate_limit.used
gh-aw.github.rate_limit.resource

10 new tests were added covering: file absent, empty file, single-entry, multi-entry (picks last), invalid JSON, and integration tests within sendJobConclusionSpan.

Pull request overview

Adds end-to-end GitHub API rate-limit observability by logging rate-limit snapshots/headers to a JSONL file during workflow execution, uploading it with job artifacts, and enriching OTLP job-conclusion spans with the latest rate-limit values.

Changes:

Introduces github_rate_limit_logger.cjs and wraps global.github to auto-log rate-limit headers for all github.rest.*.*() calls.
Uploads github_rate_limits.jsonl as part of activation and agent/unified artifacts across generated workflows.
Enriches OTLP conclusion spans with the most recent rate-limit entry read from github_rate_limits.jsonl (with test coverage).

pkg/workflow/compiler_activation_job.go

 	steps = append(steps, "          path: |\n")
 	steps = append(steps, "            /tmp/gh-aw/aw_info.json\n")
 	steps = append(steps, "            /tmp/gh-aw/aw-prompts/prompt.txt\n")
+	steps = append(steps, "            /tmp/gh-aw/"+constants.GithubRateLimitsFilename+"\n")
+	steps = append(steps, "          if-no-files-found: ignore\n")
 	steps = append(steps, "          retention-days: 1\n")


if-no-files-found: ignore applies to the whole upload step, which can silently skip uploading the required activation files (aw_info.json, prompt.txt) as well as the optional github_rate_limits.jsonl. Consider keeping the activation artifact upload strict (default/warn) for required files and adding a second, separate upload-artifact step for the rate-limit log with if-no-files-found: ignore so missing core activation files remain visible.

pkg/constants/job_constants.go

+// GithubRateLimitsFilename is the filename of the GitHub API rate-limit log written to /tmp/gh-aw/.
+// Each line is a JSON object recording the x-ratelimit-* headers (or rate-limit API snapshot)
+// captured during github.rest API calls, enabling post-run analysis of rate-limit consumption.
+const GithubRateLimitsFilename = "github_rate_limits.jsonl"


Exported identifier uses Github instead of the Go initialism GitHub. For consistency with existing constants like DefaultGitHubLockdown (pkg/constants/constants.go) and to match Go naming conventions, rename GithubRateLimitsFilename to GitHubRateLimitsFilename and update references.
