Custom Metrics Monitor

Explanation

• Before custom development, please customize and build the gateway environment first, please refer to: custom deployment

• This article describes how to customize the extension of org.apache.shenyu.plugin.metrics.spi.MetricsService.

Extension

• Create a new project and introduce the following dependencies:

<dependencies>    <dependency>        <groupId>org.apache.shenyu</groupId>        <artifactId>shenyu-plugin-base</artifactId>        <version>${project.version}</version>    </dependency></dependencies>

• Create a new class ${you class}，implements org.apache.shenyu.plugin.metrics.spi.MetricsService

public class ${you class} implements MetricsService {       /**     * Start metrics tracker.     *     * @param metricsConfig metrics config     * @param metricsRegister the metrics register     */    public void start(MetricsConfig metricsConfig, MetricsRegister metricsRegister){                //your code    }        /**     * Stop metrics tracker.     */    public void stop() {        //your code    }}

• In the project resources directory，Create a new META-INF/shenyu directory， and the new file name is : org.apache.shenyu.plugin.metrics.spi.MetricsService. add ${you spi name} = ${you class path}:

${you spi name} = ${you class path}

• Package the project and copy it to the lib or ext-lib directory of the gateway (bootstrap-bin).

• In the Admin service ---> BasicConfig ---> Plugin , Find the Monitor plugin, edit config, pay attention to the metricsName name: ${you spi name}.
