 # Prometheus Scrape Target Labels
 
+## Implementation Status
+
+| Step | Status | Notes |
+|------|--------|-------|
+| 1. Create `homelab.host` module | ✅ Complete | `modules/homelab/host.nix` |
+| 2. Update `lib/monitoring.nix` | ❌ Not started | Labels not extracted or propagated |
+| 3. Update Prometheus config | ❌ Not started | Still uses flat target list |
+| 4. Set metadata on hosts | ⚠️ Partial | Some hosts configured, see below |
+| 5. Update alert rules | ❌ Not started | |
+| 6. Labels for service targets | ❌ Not started | Optional |
+
+**Hosts with metadata configured:**
+- `ns1`, `ns2`: `role = "dns"`, `labels.dns_role = "primary"/"secondary"`
+- `nix-cache01`: `role = "build-host"` (missing `priority = "low"` from plan)
+- `vault01`: `role = "vault"`
+- `jump`: `role = "bastion"`
+- `template`, `template2`, `testvm*`: `tier` and `priority` set
+
+**Key gap:** The `homelab.host` module exists and some hosts use it, but `lib/monitoring.nix` does not extract these values—they are not propagated to Prometheus scrape targets.
+
+---
+
 ## Goal
 
 Add support for custom per-host labels on Prometheus scrape targets, enabling alert rules to reference host metadata (priority, role) instead of hardcoding instance names.
 
-**Related:** This plan shares the `homelab.host` module with `docs/plans/nats-deploy-service.md`, which uses the same metadata for deployment tier assignment.

 ## Implementation
 
-This implementation uses a shared `homelab.host` module that provides host metadata for multiple consumers (Prometheus labels, deployment tiers, etc.). See also `docs/plans/nats-deploy-service.md` which uses the same module for deployment tier assignment.

 ### 4. Set metadata on hosts
 
+⚠️ **Partial.** Some hosts configured (see status table above). Current `nix-cache01` only has `role`, missing the `priority = "low"` suggested below.
+
 Example in `hosts/nix-cache01/configuration.nix`:
 
 ```nix
 homelab.host = {
-  tier = "test";       # can be deployed by MCP (used by homelab-deploy)
   priority = "low";    # relaxed alerting thresholds
   role = "build-host";
 };
 ```
 
+**Note:** Current implementation only sets `role = "build-host"`. Consider adding `priority = "low"` when label propagation is implemented.
+
 Example in `hosts/ns1/configuration.nix`:
 
 ```nix
 homelab.host = {
-  tier = "prod";
-  priority = "high";
   role = "dns";
   labels.dns_role = "primary";
 };
 ```
 
+**Note:** `tier` and `priority` use defaults ("prod" and "high"), which is the intended behavior. The current ns1/ns2 configurations match this pattern.

 The same label propagation could be applied to service-level scrape targets. This is optional and can be deferred -- service targets are more specialized and less likely to need generic label-based filtering.
