# gcx on the local oddyssey stack One otel-lgtm container: Grafana, OTLP (gRPC and HTTP), Pyroscope's ingest port, and four datasources behind the Grafana datasource proxy. Bring it up with the oddyssey MCP tools (`odd_stack_status`, `odd_stack_up`) before configuring anything here. ## Configure an isolated context ```bash python3 <this skill's directory>/scripts/gcx_local.py ``` It takes no arguments but `--json`. It reads the host ports from the global configuration — never assumed, never hardcoded — writes an **isolated** context at a stable path so the user's own gcx contexts stay untouched, and proves it with `gcx config check`. It prints the `export GCX_CONFIG=...` line to put in front of every later gcx call, the four datasource UIDs, and the OTLP and Pyroscope endpoints an instrumented service should target. `--json` for the same, parseable. Exit 0 means gcx reached the stack. Exit 1 says which step failed: gcx missing (install it — `brew install gcx`, or the official script from github.com/grafana/gcx), or the stack unreachable (`odd_stack_up`). Re-run it after any port change. It rewrites the file whole on purpose: gcx binds a stored credential to its destination, so patching the `server:` line in place leaves the binding stale and gcx refuses it before any network use. ## Inventory the services, in one command ```bash python3 <this skill's directory>/scripts/probe_services.py <svc> [<svc> ...] --since 30m ``` One call answers what every observation asks be
