使用Prometheus和Grafana监视基于Jetty的Java应用程序

Question

我已经使用nohup和Jetty在服务器（在8091）中部署了一个Java应用程序。

我需要用普罗米修斯和格拉法纳监控那个应用程序。

 https://repo1.maven.org/maven2/io/prometheus/jmx/jmx_prometheus_javaagent/0.1.0/jmx_prometheus_javaagent-0.1.0.jar

config.yaml

[root@localhost software]# cat config.yaml
---
startDelaySeconds: 0
hostPort: 127.0.0.1:7101
jmxUrl: service:jmx:rmi:///jndi/rmi://127.0.0.1:7101/jmxrmi
ssl: false
lowercaseOutputName: true
lowercaseOutputLabelNames: true
rules:
- pattern: ".*"

我在通常的部署中使用的部署命令：（在这个目录中，存在Jetty）

nohup  -Dorg.eclipse.jetty.server.Request.maxFormContentSize=10000000 -Xms256m -Xmx256m -Djava.io.tmpdir=temp_dir -jar jetty-runner-9.0.7.v20131107.jar --log yyyy_mm_dd-java-application-1-request.log --out yyyy_mm_dd-java-application-1-output.log --port 8091 --path /java-application-1 hotfix.war >> java-application-1.log 2>&1 &

它很好用..

nohup java -javaagent:./jmx_prometheus_javaagent-0.1.0.jar=7101:config.yaml -Dorg.eclipse.jetty.server.Request.maxFormContentSize=10000000 -Xms256m -Xmx256m -Djava.io.tmpdir=epoch_temp_dir -jar jetty-runner-9.0.7.v20131107.jar --log yyyy_mm_dd-java-application-1-request.log --out yyyy_mm_dd-java-application-1-output.log --port 8091 --path /java-application-1 hotfix.war >> java-application-1.log 2>&1 &

Answer 1

您已经在config.yaml中指定了hostport和jmxurl键。但最多必须提供其中一个。移除其中一个。
