Forge Tenant - EC2 Runners

Chart	Operational question

Job runs: low peak CPU utilization (%)	Which job executions stayed below 20% peak CPU in the last 24 hours?
Job runs: high peak memory utilization (%)	Which job executions on OTel-instrumented hosts reached at least 85% peak memory?
Job runs: low peak memory utilization (%)	Which job executions on OTel-instrumented hosts stayed below 40% peak memory?
Runner classes: mean job peak CPU utilization (%)	Which repeated tenant, workflow, job, label, and instance-type combinations use the most CPU?
Runner classes: mean job peak memory utilization (%)	Which repeated tenant, workflow, job, label, and instance-type combinations use the most memory?
Job runs: high peak filesystem utilization (%)	Which job filesystems on OTel-instrumented hosts reached at least 80% utilization?

The job-run panels require the GitHub runner job URL tag and retain tenant, repository, workflow, job, runner-label, instance-type, and drill-down dimensions. Memory and filesystem panels also require the Splunk OTel host agent. Treat the runner-class panels as repeated sizing evidence; a single high or low job execution is not enough to change a runner class.

Forge AWS build queue visible backlog	Is queued-build backlog accumulating together with elevated oldest-message age?
Forge AWS queued-build DLQ sends	Did any queued-build message enter a dead-letter queue during the last five minutes?

The dashboard is scoped by its own aws_account_id, aws_region, and aws_tag_ProductFamilyName allow-lists. Missing scope values deliberately produce no matching data. The Lambda throttle-rate baselines are diagnostic because they differ materially by region; throttle count never pages alone.

Forge External Dependency Health

Chart	Operational question
GitHub checks by tenant	Can the regional monitor authenticate the GitHub App and call the organization runner API?
AWS SSM access by tenant	Can the regional monitor read the tenant's GitHub App and routing parameters?
GitHub API rate-limit budget	What percentage of the installation token's REST API budget remains?
Dependency check latency	How long do AWS SSM and GitHub checks take?
Regional probe execution	Is each tenant and regional monitor cycle still executing?

These charts use the direct-ingest metrics:

• forge.dependency.availability
• forge.dependency.latency_ms
• forge.dependency.probe_executed
• forge.dependency.rate_limit_remaining_pct

Preserve TenantName, AWSRegion, Provider, and CheckName when sending these metrics.

Reading Rules

• Prove freshness before interpreting an empty chart as healthy.
• Apply tenant, region, cluster, function, queue, table, volume, or instance filters before assigning ownership.
• A chart can aggregate several resources. Read its legend dimensions before treating the value as a single resource.
• Treat a count without a denominator as impact evidence, not an error rate.
• Compare current values with the chart window and workload demand. Idle systems legitimately have sparse metrics.
• Use Forge Tenant Impact to find the affected tenant and subsystem, then use the narrow dashboard for resource identity.
• Use Splunk Observability for availability and resource pressure. Use the Splunk Cloud Dashboard Runbook for event sequence, errors, and raw evidence.
