jmxtrans+influxdb+grafana监控zookeeper实战

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

放在跟jmxtrans.sh脚本同一个目录下即可自动加载
