SSM Run CommandのターゲットのEC2インスタンス上でCommand IDを取得したい
こんにちは、のんピ(@non____97)です。
皆さんはSSM Run CommandのターゲットのEC2インスタンス上でCommand IDを取得したいなと思ったことはありますか? 私はあります。
例えば、SSM Run Command実行中に、そのRun Commandよりも後から実行されたRun Commandを検索したい時に使いたいところです。
自身のCommand IDが分からない場合は、Run Commandで渡すコマンド内で「現在時刻よりも新しいRun Commandの実行はどれか」という処理を行うことになります。
個人的にはRun Command内で実際にコマンドを受け付けられた時間から検索するのではなく、Run Command自体が実行された時間をベースに検索したいです。また、前者の場合は、同時実行された場合に自身のRun Commandなのか、別のRun Commandなのかの判断をすることが難しいように思えます。
そのためにはターゲットなったEC2インスタンスが、どのRun Commandで実行されたのかを正確に把握する必要があります。
SSM Run Commandを実行してもCommand IDの環境変数が埋め込まれるということはありません。
これの解決方法としては、「SSM AgentのログファイルからPPIDで検索して抽出する」という方法になります。
実際にやってみます。
いきなりまとめ
- SSM AgentのログファイルからPPIDで検索して抽出できる
sleepなどで数秒待機しなければ、Run Commandを受け付けたログが出力されないので注意
やってみた
実際にやってみます。
ターゲットとするEC2インスタンスの情報は以下です。
- AMI名 : RHEL-9.2.0_HVM-20230503-x86_64-41-Hourly2-GP2
- AMI ID : ami-026ebd4cfe2c043b2 (us-east-1)
まず、SSM Run Command実行時のSSM Agentのログを確認してみます。
echo testと実行するRun Commandを実行しました。Command IDは24f814f5-80aa-429a-ac8b-206b5f249bc3です。
SSM AgentのログファイルをこちらのCommand IDでgrepします。
$ sudo grep 24f814f5-80aa-429a-ac8b-206b5f249bc3 /var/log/amazon/ssm/amazon-ssm-agent.log

}Command IDはもちろん、渡されたパラメーターなども記録されていますね。
ここで注目すべきはDocumentInformation.ProcInfo.Pidです。
以下記事でSSM Session ManagerのプロセスはSSM Agentの子プロセスであることを確認しました。
Run Commandで渡されたコマンドはssm-document-workerで実行されていそうであることを確認しました。つまり、渡されたコマンド上で親プロセスのID(PPID)を取得すれば、上述のログからCommand IDを取得することができるのではないでしょうか。
試しに以下コマンドをRun Commandで渡してみます。
#!/bin/bash
# SSM Agentのステータスの確認
systemctl status amazon-ssm-agent.service
# プロセスツリーの確認

}ということで、Run Commandで渡すコマンド上でPPIDを取得して、SSM AgentのログからCommand IDを取得することができそうです。
実際のCommand IDを取得するコマンドは以下のとおりです。
sleep 3
run_command_pid=$(echo "$PPID")
echo PPID : "$run_command_pid"
command_id=$(grep "\"Pid\":$run_command_pid" /var/log/amazon/ssm/amazon-ssm-agent.log \
| awk '{print $5}' \
| tr -d []
)
echo Command ID : "$command_id"実行すると、以下のような結果が出力されます。
PPID : 1997
Command ID : ba9b8afe-e84f-4eab-985b-67cc11ee3720ポイントはsleepです。sleepなりで待機しなければ、まだログが出力されていないようで上手く動作することができませんでした。以下のようにCommand IDを取得できるまではループする形でも良いと思います。
run_command_pid=$(echo "$PPID")
echo PPID : "$run_command_pid"
while true; do
command_id=$(grep "\"Pid\":$run_command_pid" /var/log/amazon/ssm/amazon-ssm-agent.log \
| awk '{print $5}' \
| tr -d []
)
if [[ -n "$command_id" ]]; then
break
else
sleep 1
fi
done
echo Command ID : "$command_id"SSM AgentのログファイルからPPIDで検索して抽出
SSM Run CommandのターゲットのEC2インスタンス上でCommand IDを取得してみました。
Run Command実行ごとに一意のファイルを作成したい場合にはファイル名のサフィックスにCommand IDを付与すると一目で、どのRun commandで生成されたファイルなのか分かりやすそうですね。
「Command IDを使ってこねくり回したい」という方はぜひ、試してみてください。
この記事が誰かの助けになれば幸いです。
