Functions Tab
Shows all registered function configs (FunConfig structs) for the selected service.
| Column | Description |
|---|---|
| Request Type | The API endpoint name (e.g., get_user) |
| Version | Semantic version string |
| Response Type | :sync, :async, :stream, or :none |
| Nodes | Target nodes for execution |
| Disabled | Whether the function is disabled |
Press Enter on a function to see full details including MFA, arg types, timeout, permission config, retry policy, and hooks.
Call Flows Tab
Shows all registered call flows across all services, as reported by PhoenixGenApi.Diagnostics.list_call_flows/0.
| Column | Description |
|---|---|
| Service | The service name |
| Request Type | The API endpoint name |
| Version | Config version |
| Target | Target execution node |
| Enabled | Whether the flow is enabled |
Cluster Tab
Shows the cluster topology from the perspective of the current node:
- Connected nodes — all nodes in the Erlang cluster
- Registered processes — process names registered on each node
- PhoenixGenApi services — which services are reachable on each node
- Node selection strategies — available strategies (random, hash, round_robin, sticky)
Health Tab
Shows runtime health check results:
- VM — process count, memory usage, schedulers, uptime
- Node — alive status, connected nodes
- PhoenixGenApi — status of ConfigDb, ConfigPuller, RateLimiter, WorkerPools, Relay
Status indicators:
✓— OK✗— Error○— Unknown
Stats Tab
Shows detailed VM and PhoenixGenApi statistics:
- VM — process count, port count, ETS tables, memory breakdown, reductions, GC, context switches, scheduler wall time
- PhoenixGenApi — ConfigDb count, services, rate limiter instances, worker pool status, relay status, telemetry event coverage
Large numbers are formatted with K/M suffixes for readability.
Rate Limits Tab
Shows rate limiter configuration:
- Global limits — sliding-window limits keyed by user_id, device_id, etc.
- API limits — per-service/per-request-type limits
Each limit shows the key, max requests, and window duration.
Service Config Tab (9)
Shows all service configurations from PhoenixGenApi.ConfigPuller, including online/offline status:
| Column | Description |
|---|---|
| Status | ● online or ✗ offline |
| Service | The service name |
| Nodes | Target nodes for execution |
| Module | Remote module for config pulling |
| Function | Remote function for config pulling |
Online/Offline Logic:
- Online — service appears in
introspection.services(shown in Navigation bar) - Offline — service is configured in ConfigPuller but not in Navigation bar
Press Enter on a service to see full details including nodes, module, function, args, and version check config.
The status is synchronized with the Navigation bar — if a service is shown in Navigation, it's online in Service Config.
