# Observability for OpenClaw with Opik

[OpenClaw](https://github.com/openclaw/openclaw) can send trace data to Opik through the community plugin package `@opik/opik-openclaw`.

This integration captures:

- LLM spans (`llm_input`, `llm_output`)
- Tool spans (`before_tool_call`, `after_tool_call`)
- Agent-level run metadata (`agent_end`, usage/cost diagnostics)

## Prerequisites

- [OpenClaw](https://github.com/openclaw/openclaw) version `2026.3.2` or newer.
- Opik project/workspace details (for cloud or enterprise deployments).

## Setup

::::steps{titleSize="h3"}
:::step{title="1. Install the plugin"}
```bash
openclaw plugins install @opik/opik-openclaw
```
:::

:::step{title="2. Configure the plugin"}
```bash
openclaw opik configure
```

This command validates your Opik URL, validates API key access (when required), enables the plugin, and writes plugin-scoped config.
:::

:::step{title="3. Check status and restart the OpenClaw gateway"}
```bash
openclaw opik status
openclaw gateway restart
```
:::

## Advanced configuration (manual JSON)

Use this only when you need explicit checked-in or templated plugin configuration.
For the latest plugin-specific options, see [opik-openclaw](https://github.com/comet-ml/opik-openclaw).

Add this to your OpenClaw config:

```json
{
  "plugins": {
    "entries": {
      "opik": {
        "enabled": true,
        "config": {
          "enabled": true,
          "apiUrl": "https://www.comet.com/opik/api",
          "apiKey": "your-api-key",
          "projectName": "openclaw",
          "workspaceName": "default",
          "tags": ["openclaw"]
        }
      }
    }
  }
}
```

Environment variable fallbacks are also supported:

- `OPIK_API_KEY`
- `OPIK_URL_OVERRIDE`
- `OPIK_PROJECT_NAME`
- `OPIK_WORKSPACE`

## Validate setup

::::steps{titleSize="h3"}
:::step{title="1. Check plugin status"}
```bash
openclaw opik status
```
:::

:::step{title="2. Send a message and verify traces in Opik"}
Send a message through OpenClaw and verify traces appear in the configured Opik project dashboard.
:::
::::

## Known limitation

Some OpenClaw embedded execution paths currently emit `after_tool_call` without a `sessionKey`. The plugin uses a best-effort fallback (single active trace or most recent active session), which can mis-correlate tool spans when multiple sessions run concurrently.
