序
本文主要研究一下如何使用jmxtrans+influxdb+granfa监控zookeeper
配置zookeeper jmx
在conf目录下新增zookeeper-env.sh，并使用chmod +x赋予执行权限，内容如下
JMXLOCALONLY=false
JMXDISABLE=false
JMXPORT=8999
JMXAUTH=false
JMXSSL=false
- 指定JMXPORT为8999
搭建influxdb及grafana
这里使用docker构建，如下
docker network create monitoring-network
docker run -d -p 8083:8083 -p 8086:8086 \
--net monitoring-network \
--name influxdb \
influxdb:1.5.4
curl -POST http://192.168.99.100:8086/query --data-urlencode "q=CREATE DATABASE zookeeper"
docker run -d -p 3000:3000 --net monitoring-network --name grafana grafana/grafana:5.2.4
curl 'http://admin:admin@192.168.99.100:3000/api/datasources' -X POST \
-H 'Content-Type: application/json;charset=UTF-8' \
--data-binary '{"name":"influx","type":"influxdb","url":"http://192.168.99.100:8086",
"access":"proxy","isDefault":true,"database":"zookeeper","user":"admin","password":"admin"}'
- 创建monitoring-network，让docker中的influxdb与grafana连通，然后使用rest api创建zookeeper数据库
- 创建grafana并指定net为monitoring-network，然后使用rest api配置数据源
jmxtrans配置
- 下载jmxtrans
wget http://central.maven.org/maven2/org/jmxtrans/jmxtrans/270/jmxtrans-270-all.jar
- 下载执行脚本
wget -q https://raw.githubusercontent.com/jmxtrans/jmxtrans/master/jmxtrans/jmxtrans.sh
chmod +x jmxtrans.sh
- 配置zookeeper.json

Memory,attributeName=NonHeapMemoryUsage,className=sun.management.MemoryImpl,hostname=zk,objDomain=java.lang,typeName=type\=Memory
- 之后通过select * from "Memory"可以查看具体指标数据
- 查询到有数据之后，就可以在grafana上面进行配置可视化，然后进行监控
小结
对于zookeeper、kafka之类应用来说，内置了jmx，因而其监控可以通过jmxtrans进行指标收集转换，然后输出到influxdb或者graphite或者prometheus等，最后通过grafana进行可视化及监控报警。
