Adds IncludeAllDeployments option to show all deployments, not just problem ones (where replicas don't match desired). This provides parity with the existing --kube-include-all-pods flag. - Add IncludeAllDeployments to kubernetesagent.Config - Add --kube-include-all-deployments flag and PULSE_KUBE_INCLUDE_ALL_DEPLOYMENTS env var - Update collectDeployments to respect the new flag - Add test for IncludeAllDeployments functionality - Update UNIFIED_AGENT.md documentation Addresses feedback from PR #855

# 📊 Prometheus Metrics
|
|
|
|
Pulse exposes metrics at `/metrics` (default port `9091`).
|
|
|
|
Example scrape target:
|
|
|
|
- `http://<pulse-host>:9091/metrics`
|
|
|
|
This listener is separate from the main UI/API port (`7655`). In Docker and Kubernetes you must expose `9091` explicitly if you want to scrape it from outside the container/pod.
