CLAUDE_CODE_DISABLE_OTEL_EVENT_SKIP

Updated October 31, 2026 by Alex Sorokoletov

CLAUDE_CODE_DISABLE_OTEL_EVENT_SKIP is a Claude Code environment variable: When set, prevents skipping OpenTelemetry events when no event logger is active and the session is idle, so those events are still emitted. Added in v2.1.311 and still present in v2.1.315. It is not in the official reference.

How to set it

For one session, export it in the shell that starts Claude Code:

export CLAUDE_CODE_DISABLE_OTEL_EVENT_SKIP=<value>
claude

To apply it to every session, add it to the env object of a settings file:

// ~/.claude/settings.json
{
  "env": {
    "CLAUDE_CODE_DISABLE_OTEL_EVENT_SKIP": "<value>"
  }
}
