Prometheus+Grafana学习(九)监控RocketMq

一、安装Prometheus和Grafana二、安装RocketMq三、安装Rocketmq exporter

3.1 下载源码3.2 将源码编译成jar包3.3 注册为系统服务3.4 测试 四、配置Prometheus五、配置Grafana

最简单的方式是使用docker安装，这里选择在没docker环境下编译源码安装。

github地址：https://github.com/apache/rocketmq-exporter

将上一步下载的源码rocketmq-exporter-master.zip进行编译，需要MAVEN环境。
编译：

mvn clean install

运行完后在target目录找到打好的jar包

将打好的jar：rocketmq-exporter-0.0.2-SNAPSHOT.jar上传至rocketmq所在的服务器。

vi /etc/systemd/system/rocketmq_exporter.service

添加内容：

[Service]
WorkingDirectory=/opt/soft/rocketmq_exporter/
PrivateTmp=true
Restart=always
Type=simple
ExecStart=/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.292.b10-1.el7_9.x86_64/bin/java -jar /opt/soft/rocketmq_exporter/rocketmq-exporter-0.0.2-SNAPSHOT.jar >dev/null 2>&1 &
ExecStop=/usr/bin/kill -15 $MAINPID

[Install]
WantedBy=multi-user.target

systemctl start exporter_service
systemctl enable exporter_service

修改prometheus.yml配置文件，添加一个rocketmq的job。

vi /usr/local/prometheus/prometheus.yml

将刚启动的rocketmq_exporter配置进去

# my global config
global:
  scrape_interval: 15s # Set the scrape interval to every 15 seconds. Default is every 1 minute.
  evaluation_interval: 15s # evaluate rules every 15 seconds. The default is every 1 minute.
  # scrape_timeout is set to the global default (10s).

# alertmanager configuration

重启prometheus

systemctl restart prometheus
