Garrett Delfosse 4057363f78 fix(coderd): add organization_name label to insights Prometheus metrics (#22296)
## Description

When multiple organizations have templates with the same name, the
Prometheus `/metrics` endpoint returns HTTP 500 because Prometheus
rejects duplicate label combinations. The three `coderd_insights_*`
metrics (`coderd_insights_templates_active_users`,
`coderd_insights_applications_usage_seconds`,
`coderd_insights_parameters`) used only `template_name` as a
distinguishing label, so two templates named e.g. `"openstack-v1"` in
different orgs would produce duplicate metric series.

This adds `organization_name` as a label to all three insight metric
descriptors to disambiguate templates across organizations.

## Changes

**`coderd/prometheusmetrics/insights/metricscollector.go`**:
- Added `organization_name` label to all three metric descriptors
- Added `organizationNames` field (template ID → org name) to the
`insightsData` struct
- In `doTick`: after fetching templates, collect unique org IDs, fetch
organizations via `GetOrganizations`, and build a
template-ID-to-org-name mapping
- In `Collect()`: pass the organization name as an additional label
value in every `MustNewConstMetric` call

**`coderd/prometheusmetrics/insights/testdata/insights-metrics.json`**:
Updated golden file to include `organization_name=coder` in all metric
label keys.

Metrics Documentation Generator

This tool generates the Prometheus metrics documentation at docs/admin/integrations/prometheus.md.

How It Works

The documentation is generated from two metrics files:

  1. metrics (static, manually maintained)
  2. generated_metrics (auto-generated, do not edit)

These files are merged and used to produce the final documentation.

metrics (static)

Contains metrics that are not directly defined in the coder source code:

  • go_*: Go runtime metrics
  • process_*: Process metrics from prometheus/client_golang
  • promhttp_*: Prometheus HTTP handler metrics
  • coder_aibridged_*: Metrics from external dependencies

Note

This file also contains edge cases where metric metadata cannot be accurately extracted by the scanner (e.g., labels determined by runtime logic). Static metrics take priority over generated metrics when both files contain the same metric name.

Edit this file to add metrics that should appear in the documentation but are not scanned from the coder codebase, or to manually override metrics where the scanner generates incorrect metadata (e.g., missing runtime-determined labels like in agent_scripts_executed_total).

generated_metrics (auto-generated)

Contains metrics extracted from the coder source code by the AST scanner (scanner/scanner.go).

Do not edit this file directly. It is regenerated by running:

make scripts/metricsdocgen/generated_metrics

Updating Metrics Documentation

To regenerate the documentation after code changes:

make docs/admin/integrations/prometheus.md

This will:

  • Run the scanner to update generated_metrics
  • Merge metrics and generated_metrics metric files
  • Update the documentation file
