# Kata Metrics in Rust Runtime(runtime-rs)
|
||||
|
||||
Rust Runtime(runtime-rs) is responsible for:
|
||||
|
||||
- Gather metrics about `shim`.
|
||||
- Gather metrics from `hypervisor` (through `channel`).
|
||||
- Get metrics from `agent` (through `ttrpc`).
|
||||
|
||||
---
|
||||
|
||||
Here are listed all the metrics gathered by `runtime-rs`.
|
||||
|
||||
> * Current status of each entry is marked as:
|
||||
> * ✅：DONE
|
||||
> * 🚧：TODO

### Kata Hypervisor
|
||||
|
||||
Different from golang runtime, hypervisor and shim in runtime-rs belong to the **same process**, so all previous metrics for hypervisor and shim only need to be gathered once. Thus, we currently only collect previous metrics in kata shim.
|
||||
|
||||
At the same time, we added the interface(`VmmAction::GetHypervisorMetrics`) to gather hypervisor metrics, in case we design tailor-made metrics for hypervisor in the future. Here're metrics exposed from [src/dragonball/src/metric.rs](https://github.com/kata-containers/kata-containers/blob/main/src/dragonball/src/metric.rs).
|
||||

||||
