**1. Severity of the issue: (select one)**  
 High: Completely blocks me.

**2. Environment:**

- Ray version: 2.46.0
- Python version: 3.10.12
- OS: linux kernel 5.10.134-16.101.al8.x86\_64
- Cloud/Infrastructure:
- Other libs/tools (if relevant):

**3. Repro steps / sample code:** (optional, but helps a lot!)

```auto
Your example code

```

**4. What happened vs. what you expected:**

- Expected: All system metrics are available
- Actual: some metrics are unavailable

I started a Ray cluster using the command: `ray start --head --port=6379 --metrics-export-port=8080` and with `curl http://127.0.0.1:8080/metrics` to fetch the system metrics. But I only got a small subset of them (e.g., `ray_node_memory_available` ). Many other metrics, such as `ray_object*` and `ray_internal*` , are missing.
