libvirt + prometheus + grafana

KVM を libvirt でホストしていて、prometheus と grafana で観測したい場合。 exporter の実装は 3 種類みつかる。流儀が異なり、メトリクスが異なるので注意。

• libvirt_exporter (Go)
  • grafana json + prometheus recording rule
  • prometheus の設定ファイルで recording rule を有効化します。
  • job 名は libvirt_exporter

Chromium OS ft. Docker

Chromium OS is cool. Chromium OS with crouton is cooler. Chromium OS with Docker is even cooler. This is specifically a guide for the Chromebook Pixel 2 (2015), but I can't think of any reason it wouldn't work with other devices.

1. Create a build environment
2. Customize the kernel
3. Build Chromium OS
4. Flash Chromium OS to USB
5. Install Chromium OS
