# Performance Metrics
|
|
|
|
Cloud Hypervisor provides a [performance metrics](https://github.com/cloud-hypervisor/cloud-hypervisor/tree/main/performance-metrics)
|
|
binary for users to generate metrics data from their own
|
|
environment. This document describes how to generate metrics data
|
|
quickly by using Cloud Hypervisor's development script,
|
|
e.g. `dev_cli.sh`. The only prerequisite is [Docker installation](https://docs.docker.com/engine/install/).
|
|
Please note that upon its first invocation, this script will pull a
|
|
fairly large container image.
|
|
|
|
To generate metrics data for all available performance tests (including
|
|
boot time, block I/O throughput, and network throughput & latency) and
|
|
output the result into a json file:
|
|
|
|
```
|
|
$ ./scripts/dev_cli.sh tests --metrics -- -- --report-file /tmp/metrics.json
|
|
```
|
|
|
|
To get a list of available performance tests:
|
|
|
|
```
|
|
$ ./scripts/dev_cli.sh tests --metrics -- -- --list-tests
|
|
```
|
|
|
|
To generate metrics data for selected performance tests, e.g. boot time only:
|
|
|
|
```
|
|
$ ./scripts/dev_cli.sh tests --metrics -- -- --report-file /tmp/metrics.json --test-filter boot_time
|
|
```
