WSO2 API Microgateway のスタートアップ設定

ゲートウェイの実行可能ファイルの JVM 引数に Java エージェントを追加することで、WSO2 API Microgateway をインストゥルメント化できます。Java エージェントをアタッチするには、環境に応じて次の手順を実行します。

注: Java エージェントは、エントリとイグジットで HTTP1 プロトコルのみをサポートします。

Add the Java Agent in Linux or macOS

Open the executable file named "gateway" at <MGW_HOME>/bin in a text editor.
In java_cmd_gateway () under $JAVA_OPTS, add :
```
-javaagent:/path_to_appagent/javaagent.jar
```
Save the executable and start the gateway.

Navigate to the docker container in which the microgateway is running using the following command:
```
docker exec -it <container_id> /bin/bash
```
Open the executable file named "gateway" at wso2/bin inside the docker container in a text editor.
In java_cmd_gateway () under $JAVA_OPTS, add :
```
-javaagent:/path_to_appagent/javaagent.jar
```
Save the gateway file.
Fetch the process id of Java process running inside the container using the following command:
```
ps -eaf | grep java
```
Kill the process <process_ID>:
```
kill -9 <process_ID>
```
Start the gateway again by running the jar:
```
wso2/bin/gateway <executable_jar>
```

Open the executable file named "gateway" at <MGW_HOME>/bin in a text editor.
In runTools under "SET JAVA_CMD", after "%JAVA_OPTS% ^" add the following:
```
-javaagent:/path_to_appagent/javaagent.jar
```
Save the executable and start the gateway.
