Metrics Plugin Instructions#

Metrics plugin The plugin is used by the gateway to monitor its own running status (JVM related), request response delay, QPS, TPS and other related metrics.

Use of plugins#

Add the metrics dependency in the gateway's pom.xml file.

<dependency>    <groupId>org.apache.shenyu</groupId>    <artifactId>shenyu-spring-boot-starter-plugin-metrics</artifactId>    <version>${project.version}</version></dependency>

Edit the following in the gateway's configuration yaml file

shenyu:  metrics:    enabled: false #Set to true to enable    name : prometheus    host: #exposed ip    port: 8090 #Exposed port    jmxConfig: #jmxConfiguration    props:      jvm_enabled: true #Enable jvm monitoring indicators

For specific metrics information, please check the official website description:

Cache plugin instructions#

The Cache plugin can cache the results of the target service, and also allows the user to configure the expiration time of the cached results.

Use of plugins#

Add the Cache dependency in the gateway's pom.xml file.

<dependency>    <groupId>org.apache.shenyu</groupId>    <artifactId>shenyu-spring-boot-starter-plugin-cache</artifactId>    <version>${project.version}</version></dependency>

It is suitable for scenarios where data is not frequently updated, requires a large number of calls, and does not require high data consistency.

Logging RocketMQ plugin instructions#

The Apache ShenYu gateway receives the client request, forwards the request to the server, and returns the server result to the client. The gateway can record the detailed information corresponding to each request, such as: request time, request parameters, request path, response result, response status code, time-consuming, upstream IP, exception information, etc.

Logging-RocketMQ plugin is a plugin that records and sends access logs to the RocketMQ cluster.

Use of plugins#

Add dependencies in the gateway's pom.xml file.

<dependency>    <groupId>org.apache.shenyu</groupId>    <artifactId>shenyu-spring-boot-starter-plugin-logging-rocketmq</artifactId>    <version>${project.version}</version></dependency>

The specific configuration and the function of each parameter can be found on the official website:
