Codex

Overview​

The OpenAI Codex input receives OTel telemetry data emitted by Codex, OpenAI's agentic coding tool, for observability and telemetry.

Requirements​

There is no configuration needed at the input level in Monad. Simply create a Codex input and attach it to a pipeline.

All configuration is done on the Codex side, where you point its OTel exporter to the Monad endpoint with the appropriate authentication headers.

Codex Configuration​

To send telemetry from Codex to Monad, configure the OpenTelemetry exporter in your Codex settings. You will need:

  1. A Monad organization API key with the pipeline:data:write permission
  2. The pipeline ID of the pipeline with your Codex input

Required Headers​

HeaderValueDescription
AuthorizationApiKey <your-api-key>Monad organization API key
Monad-Pipeline-Id<your-pipeline-id>The pipeline ID containing the Codex input

Example Configuration​

Add the following to your Codex TOML configuration file:

[otel]
exporter = { otlp-grpc = {
  endpoint = "https://app.monad.com:4317",
  headers = { "Authorization" = "ApiKey <your-api-key>", "Monad-Pipeline-Id" = "<your-pipeline-id>" }
}}
