Codex
Send OpenAI Codex CLI session traces to your Everstack instance.
Codex (OpenAI) exports OpenTelemetry via the [otel] table in
~/.codex/config.toml.
See Trace Coding Agents for the endpoints, API key, and what Everstack renders.
Configuration
[otel]
exporter = "otlp-http"
endpoint = "https://<your-instance>/v1/traces"
# headers are sent on every export
headers = { Authorization = "Bearer <your-api-key>" }Codex's metrics exporter defaults to an internal sink, and OTLP coverage is
uneven across subcommands — full in the interactive TUI, none in
codex mcp-server. Confirm the exact keys against the Codex config reference
for your version.
Notes
- Codex emits token counts but no cost — Everstack computes it from your model-catalog pricing.
- Codex groups a session under a
conversation.id; Everstack treats that as the session grouping key.
