状態取得の方法いろいろ

SONiCにおける動作状態の確認方法は、主にCLIとgRPCがあります。これらについてざっと紹介します。出力例は長いので折りたたませてありますので、具体例を確認したい場合は広げてご覧ください。

CLIによる動作状態取得

SONiCはDebianベースのOSですので、通常のLinuxホストと同様にログインして操作することができます。コンソールもしくはsshでのログインが標準で提供されます。

ログインに必要なアカウント情報ですが、バイナリ提供されているイメージを使っている場合

Username: admin
Password: YourPaSsWoRd
となっています。本格的に利用する場合は、各自でビルドする際に本パラメータを変更しておくのが安全です。ログインするとbashが起動します。lsやpsなど通常のLinuxコマンドを使うことができます。

CLIでの動作確認には、SONiC用に作成された show コマンドを使います。下記では、SONiC-VS (Virtual Switch)での実行結果を紹介します。

バージョンの確認

SONiCのバージョン情報を表示します。イメージをビルドする際に用いられた`git`のbranchやcommitを含めたものが表示されます。

gRPCによる状態取得

telemetry serviceが正常に動作していれば、[gNMI GET](https://github.com/jipanyang/gnxi/tree/master/gnmi_get)を使って状態取得ができます。

下記例においていくつかのパラメータは設定や環境に依存します。例そのままコピペでなく、書き換えてお試しください。 - `-target_addr`に指定するのは実機のマネジメントポートに付与されたIPアドレスです。 - ポート8080はSONiC側で特に設定を支持しなかったときのポート番号になります。別ポートを使用する場合はSONiCの`config_db.json`に設定を加えてください。
