See code comments in `Application.java` for further details. + +If you already have a Graphite server, make sure that UDP is enabled (set `ENABLE_UDP_LISTENER = True` in carbon.conf). + +If Graphite is not on your local machine, replace `localhost` in `Application.java` with the hostname or IP address of your Graphite server. + +If you want to use TCP instead of UDP, use `com.codahale.metrics.graphite.Graphite` instead of `com.codahale.metrics.graphite.GraphiteUDP`, as shown here: http://metrics.dropwizard.io/3.1.0/manual/graphite/ + +If you can't be bothered to set up a Graphite server right now, you can simulate it by running `nc -ul 2003` on Linux. If you don't have `nc`, use `yum search netcat` to find a suitable package to install (e.g. nmap-ncat.x86_64). + +When you're ready to try it: +`mvn clean install` +`java -jar target/camel-metrics-example-0.0.1-SNAPSHOT.jar` + +You will see logging from the "Fast" and "Slow" routes, and metrics will be sent to Graphite (or nc) every 5 seconds. http://git-wip-us.apache.org/repos/asf/camel/blob/813622af/examples/camel-example-springboot-metrics/pom.xml ---------------------------------------------------------------------- diff --git a/examples/camel-example-springboot-metrics/pom.xml b/examples/camel-example-springboot-metrics/pom.xml new file mode 100644 index 0000000..38e4bdf --- /dev/null +++ b/examples/camel-example-springboot-metrics/pom.xml @@ -0,0 +1,96 @@ +<project xmlns="http://maven.apache.org/POM/4.0.0"; xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; + xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd";> + <modelVersion>4.0.0</modelVersion> + <groupId>org.apache.camel</groupId> + <artifactId>camel-example-springboot-metrics</artifactId> + <version>0.0.1-SNAPSHOT</version> + + <parent> + <!-- Spring Boot supplies the version numbers for dependencies, and some + other default config --> + <groupId>org.springframework.boot</groupId> + <artifactId>spring-boot-starter-parent</artifactId> + <version>1.3.0.BUILD-SNAPSHOT</version> + <relativePath></relativePath> + </parent> + + <properties> + <java.version>1.8</java.version> + <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> + <start-class>org.apache.camel.example.springboot.metrics.Application</start-class> + <camel.version>2.16.0</camel.version> + </properties> + + + + <dependencies> + <dependency> + <groupId>org.jolokia</groupId> + <artifactId>jolokia-core</artifactId> + </dependency> + <dependency> + <groupId>org.springframework.boot</groupId> + <artifactId>spring-boot-starter-web</artifactId> + </dependency> + <dependency> + <groupId>org.springframework.boot</groupId> + <artifactId>spring-boot-starter-actuator</artifactId> + </dependency> + <dependency> + <groupId>io.dropwizard.metrics</groupId> + <artifactId>metrics-core</artifactId> + </dependency> + <dependency> + <groupId>io.dropwizard.metrics</groupId> + <artifactId>metrics-graphite</artifactId> + </dependency> + <dependency> + <groupId>org.apache.camel</groupId> + <artifactId>camel-metrics</artifactId> + <version>${camel.version}</version> + </dependency> + <dependency> + <groupId>org.apache.camel</groupId> + <artifactId>camel-spring-boot</artifactId> + <version>${camel.version}</version> + </dependency> + + </dependencies> + + <build> + <plugins> + <plugin> + <groupId>org.springframework.boot</groupId> + <artifactId>spring-boot-maven-plugin</artifactId> + </plugin> + </plugins> + </build> + + <pluginRepositories> + <pluginRepository> + <id>spring-snapshots</id> + <url>http://repo.spring.io/snapshot</url> + </pluginRepository> + <pluginRepository> + <id>spring-milestones</id> + <url>http://repo.spring.io/milestone</url> + </pluginRepository> + </pluginRepositories> + + <repositories> + <repository> + <id>spring-snapshots</id> + <url>http://repo.spring.io/snapshot</url> + </repository> + <repository> + <id>spring-milestones</id> + <url>http://repo.spring.io/milestone</url> + </repository> + </repositories> + + +</project> + + + + http://git-wip-us.apache.org/repos/asf/camel/blob/813622af/examples/camel-example-springboot-metrics/src/main/java/org/apache/camel/example/springboot/metrics/Application.java ---------------------------------------------------------------------- diff --git a/examples/camel-example-springboot-metrics/src/main/java/org/apache/camel/example/springboot/metrics/Application.java b/examples/camel-example-springboot-metrics/src/main/java/org/apache/camel/example/springboot/metrics/Application.java new file mode 100644 index 0000000..81539d9 --- /dev/null +++ b/examples/camel-example-springboot-metrics/src/main/java/org/apache/camel/example/springboot/metrics/Application.java @@ -0,0 +1,119 @@ +/** + * Licensed to the Apache Software Foundation (ASF) under one or more + * contributor license agreements.
