Hey folks! So I finally got my little agent doing some cool stuff with the nano_claw prototype, and now I want to see its operational logs in our Splunk dashboard. I know OpenClaw can spit out JSON events to stdout or a file, and I know Splunk has that HTTP Event Collector (HEC), but I'm a bit fuzzy on the *practical glue*.

I'm picturing a lightweight forwarder—maybe a tiny Python service?—that picks up the JSON lines from the agent's log file and ships them via Splunk's HEC API. I want to avoid heavy dependencies; it should just run in the same container/pod as the agent.

Has anyone set this up? My main questions are:

1. What's the best way to *tail* the log file in real-time? Just a simple loop, or use something like `watchdog`?
2. Are there any gotchas with the JSON formatting? Do I need to wrap the agent's event in a specific envelope for HEC?
3. How do you handle failures or Splunk being down? A small buffer?

Here's the kind of event I'm working with from the agent:
```json
{
"timestamp": "2024-05-15T10:30:00Z",
"level": "INFO",
"event_type": "tool_call",
"session_id": "sess_abc123",
"data": {
"tool_name": "web_search",
"parameters": {"query": "latest CVE"},
"duration_ms": 1200
}
}
```

And I assume the HEC request looks roughly like:
```python
requests.post(hec_url, json=event, headers={'Authorization': f'Splunk {hec_token}'})
```

But I'd love to see a complete, robust example, especially around error handling and maybe batching. Also, any tips on field extractions or CIM mapping later in Splunk would be awesome!
