grafana+prometheus+hiveserver2(jmx_exporter+metrics)-编程知识

监控图

一、hiveserver2开启metrics，并启动jmx_exporter

1、修改hive-site.xml文件开启metrics

<property><name>hive.server2.metrics.enabled</name><value>true</value>
</property>
<property><name>hive.service.metrics.codahale.reporter.classes</name><value>org.apache.hadoop.hive.common.metrics.metrics2.JmxMetricsReporter</value>
</property>

2、启动时带上jmx_exporter
①下载jmx_exporter安装包放在服务器上
下载路径：
prometheus常用exporter下载地址大全

/usr/local/jmx_expoter/jmx_prometheus_javaagent-0.9.0.jar
/usr/local/jmx_expoter/hiveserver2.yaml

/usr/local/jmx_expoter/hiveserver2.yaml文件内容

rules:- pattern: '.*'

②修改hive安装目录bin/hive里的内容

##把这段内容
export HADOOP_CLIENT_OPTS="$HADOOP_CLIENT_OPTS -Dlog4j.configurationFile=hive-log4j2.properties"
##修改为，增加上 指定jar和yaml文件和指定jmx端口随意9909
export HADOOP_CLIENT_OPTS="$HADOOP_CLIENT_OPTS java -javaagent:/usr/local/jmx_expoter/jmx_prometheus_javaagent-0.9.0.jar=9909:/usr/local/jmx_expoter/hiveserver2.yaml -Dlog4j.configurationFile=hive-log4j2.properties"

3、查看都有哪些metrics
访问http://hiveIP:9909/metrics
在这里插入图片描述

二、配置prometheus

prometheus下载地址
1、prometheus.yaml增加一下配置

scrape_configs:- job_name: "hiveserver2"static_configs:- targets: ["hiveIp:9909","hiveIp:9909"]

2、启动

nohup ./prometheus --config.file=prometheus.yaml --web.listen-address=:9090 --storage.tsdb.retention=7d > ./prometheus.log 2>&1 &

三、配置grafana

1、配置prometheus数据源
如果数据源不是这个名字，下边的json记得改名字
2、dashboards import json
其他指标可以自行添加panels(嵌板)
