Netcat is available in the base image (`ubuntu:resolute`) and is sufficient for serving simple HTTP responses. This avoids adding Python, Node.js, or Go dependencies to the runner image. + +**Trade-offs:** + +- (+) Zero additional dependencies. +- (+) Minimal image size impact. +- (+) Simple to debug and modify. +- (-) Single-threaded HTTP server (one request at a time). +- (-) No request routing (all paths return metrics). +- (-) Limited HTTP compliance (HTTP/1.0 only). + +**Review:** If scrape concurrency becomes an issue, consider `socat` (multi-connection) or a lightweight Go binary. + +### Decision: File-Based Metrics Transfer + +**Rationale:** The collector writes metrics to a file; the server reads the file. This decouples the two processes and allows atomic updates via `mv`. No shared memory or IPC required. + +**Trade-offs:** + +- (+) Simple, robust, no race conditions (atomic `mv`). +- (+) Easy to debug (`cat /tmp/runner_metrics.prom`). +- (-) Slight latency (up to 30s stale data between updates). +- (-) Disk I/O on each update (minimal β€” file is < 2KB). + +### Decision: CSV Job Log Format + +**Rationale:** A simple CSV format (`timestamp,job_id,status,duration,queue_time`) is easy to parse with standard shell tools (`grep`, `awk`, `read`). No external parsers needed. + +**Trade-offs:** + +- (+) Human-readable and inspectable. +- (+) Easy to parse with bash built-ins. +- (-) No schema enforcement. +- (-) Unbounded growth (mitigated by reading only recent entries for queue time). + +### Decision: Stub Cache Metrics + +**Rationale:** BuildKit cache logs reside on the Docker host, not inside the runner container.

Container Not Running + +```bash +docker ps | grep github-runner +``` + +**Fix:** Start the container: + +```bash +docker compose -f docker/docker-compose.production.yml up -d +``` + +#### 2. Port Not Mapped + +```bash +docker port +``` + +**Fix:** Verify the compose file has the correct port mapping: + +```yaml +ports: + - "9091:9091" # Standard runner + - "9092:9091" # Chrome runner + - "9093:9091" # Chrome-Go runner +``` + +#### 3. Metrics Server Not Started + +```bash +docker exec ps aux | grep metrics-server +``` + +**Fix:** The metrics server is launched by the entrypoint script. Check logs: + +```bash +docker logs 2>&1 | grep -i "metrics" +``` + +If the server is not running, restart the container: + +```bash +docker compose -f docker/docker-compose.production.yml restart +``` + +#### 4. Port Conflict + +Another service may be using port 9091 on the host. + +```bash +lsof -i :9091 +# or +ss -tlnp | grep 9091 +``` + +**Fix:** Change the host port in the compose file: + +```yaml +ports: + - "9094:9091" # Use alternate host port +``` + +#### 5. Netcat Not Available + +```bash +docker exec which nc +``` + +**Fix:** Netcat (`nc`) should be included in the base image. If missing, rebuild the image. + +--- + +## Problem: Metrics Not Updating + +### Symptom + +`github_runner_uptime_seconds` or `github_runner_last_update_timestamp` does not change between requests. + +### Possible Causes and Fixes + +#### 1. Collector Script Not Running + +```bash +docker exec ps aux | grep metrics-collector +``` + +**Fix:** Check the collector log for errors: + +```bash +docker exec cat /tmp/metrics-collector.log +``` + +Restart the container if the collector crashed: + +```bash +docker restart +``` + +#### 2. Metrics File Not Writable + +```bash +docker exec ls -la /tmp/runner_metrics.prom +``` + +**Fix:** Ensure `/tmp` is writable (it should be by default). Check disk space: + +```bash +docker exec df -h /tmp +``` + +#### 3. Update Interval Too Long + +The default update interval is 30 seconds. Wait at least 30 seconds between checks. + +```bash +# Watch metrics update in real time +watch -n 5 'curl -s http://localhost:9091/metrics | grep uptime' +``` + +**Fix:** Reduce the interval via environment variable: + +```yaml +environment: + METRICS_UPDATE_INTERVAL: "15" # Update every 15 seconds +``` + +--- + +## Problem: Grafana Dashboard Shows "No Data" + +### Symptom + +Dashboard panels display "No data" or are empty. + +### Possible Causes and Fixes + +#### 1. Prometheus Datasource Not Configured + +In Grafana: + +1. Go to **Configuration β†’ Data Sources**. +2. Verify a Prometheus datasource exists. +3. Click **Save & Test** to confirm connectivity. + +#### 2. Prometheus Not Scraping Runners + +Check Prometheus targets: + +1. Open `http://:9090/targets`. +2. Look for `github-runner-*` jobs. +3. Targets should show state `UP`. + +**Fix:** Add runner targets to your `prometheus.yml`: + +```yaml +scrape_configs: + - job_name: "github-runner-standard" + static_configs: + - targets: [":9091"] +``` + +Reload Prometheus: + +```bash +curl -X POST http://localhost:9090/-/reload +``` + +#### 3. Datasource Name Mismatch + +The dashboards use `${DS_PROMETHEUS}` as a datasource input variable. During import, you must select your Prometheus datasource. + +**Fix:** Re-import the dashboard and select the correct datasource at the import prompt. + +#### 4. Time Range Too Narrow + +If the runner was just deployed, there may not be enough data for the selected time range. + +**Fix:** Set the dashboard time range to "Last 15 minutes" or "Last 1 hour". + +#### 5. No Jobs Executed Yet + +Job metrics (`github_runner_jobs_total`, `github_runner_job_duration_seconds`) only populate after jobs run. + +**Fix:** Trigger a test workflow in your repository, or check panels that show runner status (which updates immediately). + +--- + +## Problem: Prometheus Target Shows DOWN + +### Symptom + +Prometheus targets page shows the runner target with state `DOWN` and an error message. + +### Possible Causes and Fixes + +#### 1. Network Connectivity + +Prometheus cannot reach the runner on the configured port. + +```bash +# From the Prometheus host/container, test connectivity +curl http://:9091/metrics +``` + +**Fix for Docker networks:** Put Prometheus and runners on the same Docker network: + +```yaml +# In your Prometheus docker-compose +networks: + monitoring: + external: true + +# In runner docker-compose, add: +networks: + monitoring: + external: true +``` + +#### 2. Firewall Blocking + +```bash +# Check if port is open +nc -zv 9091 +``` + +**Fix:** Open port 9091 in your firewall rules. + +#### 3. Scrape Timeout + +The metrics endpoint must respond within the `scrape_timeout` (default 10s). + +```bash +# Measure response time +time curl -s http://localhost:9091/metrics > /dev/null +``` + +**Fix:** If response is slow, increase the scrape timeout: + +```yaml +- job_name: "github-runner-standard" + scrape_timeout: 15s +``` + +--- + +## Problem: Job Counts Not Incrementing + +### Symptom + +`github_runner_jobs_total` stays at 0 despite running jobs. + +### Possible Causes and Fixes + +#### 1. Job Hooks Not Configured + +The runner must have job hooks set via environment variables. + +```bash +docker exec env | grep ACTIONS_RUNNER_HOOK +``` + +Expected output: + +``` +ACTIONS_RUNNER_HOOK_JOB_STARTED=/home/runner/job-started.sh +ACTIONS_RUNNER_HOOK_JOB_COMPLETED=/home/runner/job-completed.sh +``` + +**Fix:** These are configured in the entrypoint scripts. Verify the entrypoint script sets them: + +```bash +docker exec cat /home/runner/entrypoint.sh | grep HOOK +``` + +#### 2. Jobs Log Not Writable + +```bash +docker exec ls -la /tmp/jobs.log +docker exec cat /tmp/jobs.log +``` + +**Fix:** Ensure `/tmp/jobs.log` exists and is writable. + +#### 3. Hook Scripts Not Executable + +```bash +docker exec ls -la /home/runner/job-started.sh /home/runner/job-completed.sh +``` + +**Fix:** Scripts should have execute permission. This is set during the Docker build. + +--- + +## Problem: High Memory or CPU Usage + +### Symptom + +Runner container using more resources than expected. + +### Diagnostic + +```bash +# Check resource usage +docker stats --no-stream + +# Check metrics processes specifically +docker exec ps aux --sort=-%mem | head -10 +``` + +### Fixes + +#### Reduce Scrape Frequency + +```yaml +environment: + METRICS_UPDATE_INTERVAL: "60" # Reduce from 30s to 60s +``` + +#### Check Jobs Log Growth + +```bash +docker exec wc -l /tmp/jobs.log +``` + +If the log has thousands of entries, the histogram calculation may be slow. + +**Fix:** The collector processes recent entries (last 100 for queue time). For very long-running containers, consider restarting to reset the log. + +#### Resource Limits + +Set container resource limits in the compose file: + +```yaml +deploy: + resources: + limits: + cpus: "2.0" + memory: 2G +``` + +--- + +## Problem: Cache Metrics Always Zero + +### Symptom + +`github_runner_cache_hit_rate` reports 0 for all cache types. + +### Explanation + +Cache metrics are currently **stubbed** β€” they always return 0. This is by design: + +- BuildKit cache logs exist on the Docker host, not inside the runner container. +- APT and npm caches are internal to the build process and not easily instrumented from the runner. + +See [PROMETHEUS_METRICS_REFERENCE.md](PROMETHEUS_METRICS_REFERENCE.md) for details. + +**Future work:** A sidecar container or host-side exporter could provide real cache metrics. + +--- + +## Collecting Diagnostic Information + +If you need to file a bug report, gather this information: + +```bash +# 1.
