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
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)
