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。

電源の状態確認
PSUの状態を確認できます。仮想マシン実装の場合は取得できません。
admin@sonic:~$ show platform psustatus
Error! Failed to get the number of PSUs!
Error: fail to get psu status from state DB
稼働時間の確認
最後に起動してからの稼働時間を確認できます。累積ではありません。
admin@sonic:~$ show uptime
up 2 hours, 49 minutes
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。

状態取得における注意点
- ソフトウェア実装 (SONiC-VS, SONiC-P4) では取得できない情報があります。たとえば前出のgRPCによる状態取得は、SONiC-VSでは機能しません。
