Summary by CodeRabbit
WalkthroughThe change adds configurable metrics namespaces across REST, Site Agent, and workflow services. It adds workflow site-health gauges, shared site-name caching, DPS API wiring, deterministic Temporal timing, and removes PagerDuty configuration and utilities. ChangesMetrics namespaces and service wiring
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟡 Moderate · up to This change adds site inventory and certificate-expiry alerts and revises metric namespace handling, but stale alert series can persist indefinitely in highly available deployments and an explicitly empty namespace can publish metrics under an unintended name. The PR is not merge-ready until these bounded correctness and configuration issues are addressed, with the existing test-organization follow-up completed or explicitly accepted. 🚥 Pre-merge checks | ✅ 4 | ❌ 1❌ Failed checks (1 warning)

There was a problem hiding this comment.
When a Site first exceeds the threshold, MonitorInventoryReceiptForAllSites publishes it and then changes its status from Registered to Error; on the next @every 3m run, the Registered-only query excludes that still-disconnected Site and this Reset deletes its series. Because this change also removes the PagerDuty notification, the replacement alerting signal resolves while the outage continues (and any alert with a multi-cycle for interval may never fire); retain disconnected/Error Sites in the published set until inventory resumes.

Normalize MetricsNamespace after flag.Parse().
flag.StringVar binds --metricsNamespace directly to conf.MetricsNamespace, but the fallback runs before flag.Parse(). Therefore, --metricsNamespace="" can overwrite conftypes.DefaultMetricsNamespace, and the metric constructors receive an empty namespace. Add a test for this explicit empty value.

Prevent stale Site alert series in HA deployments.
Line 51 clears gauges only in the worker process that executes the cycle. Other Cloud worker replicas retain their prior series. If a Site is deleted or deregistered after another replica published it, max by (site_id) still returns that stale series and the inventory alert can remain active indefinitely.
Ensure every replica clears and republishes each cycle. Alternatively, publish a per-replica freshness signal and exclude stale replicas in the alert query.
