JMXtrans + InfluxDB + Grafana实现Zookeeper性能指标监控

一、总体效果图

这里是将集群全部放在一起,可以根据自己的审美看怎么放

 

二、监控指标

 

 

其中有些指标与第一篇Zookeeper通过四字命令基础监控(Zabbix)的四字命令的指标是有重复的,二者选一个则可
 

三、实现

1、influxdb的安装

1)设置yum源

cat <<EOF | sudo tee /etc/yum.repos.d/influxdb.repo
[influxdb]
name = InfluxDB Repository - RHEL \$releasever
baseurl = https://repos.influxdata.com/rhel/\$releasever/\$basearch/stable
enabled = 1
gpgcheck = 1
gpgkey = https://repos.influxdata.com/influxdb.key
EOF

 

2)安装influxdb

yum install influxdb
systemctl start influxdb

 

3)修改配置文件(元数据以及数据存放目录)

[root@ip-172-0-0-7 influxDB]# cat /etc/influxdb/influxdb.conf |grep "^\s*[^# \t].*$"
[meta]
  dir = "/influxDB/meta"
[data]
  dir = "/influxDB/data"
  wal-dir = "/influxDB/wal"
  series-id-set-cache-size = 100
[coordinator]
[retention]
[shard-precreation]
[monitor]
[http]
[logging]
[subscriber]
[[graphite]]
[[collectd]]
[[opentsdb]]
[[udp]]
[continuous_queries]
[tls]

 

4、数据目录授权

chown -R influxdb.influxdb /influxDB

 

5、重启influxdb

systemctl restart influxdb

 

6、创建zookeeper数据库,以及创建账号密码

CREATE USER "admin" WITH PASSWORD "admin" WITH ALL PRIVILEGES
create database zookeeper

 

2、zookeeper上打开JMX

1)vim ${Zookeeper-Home}/conf/zookeeper-env.sh
JMXLOCALONLY=false
JMXDISABLE=false
JMXPORT=8999
JMXAUTH=false
JMXSSL=false

 

2、重启Zookeeper

./zkServer.sh restart

 

3、JMXtrans的安装

1)安装配置jmxtrans

下载地址https://oss.sonatype.org/content/repositories/snapshots/org/jmxtrans/jmxtrans/ 这里有最新的版本,用老的版本有一些问题 ;JMXtrans可以随意安装在任何一台机器上,不是必须安装在Zookeeper机器上,只要JMXtrans与Zookeeper机器的网络及端口是通的就可以

wget https://oss.sonatype.org/content/repositories/snapshots/org/jmxtrans/jmxtrans/271-SNAPSHOT/jmxtrans-271-20190109.091025-10.rpm
yum -y install jmxtrans-271-20190109.091025-10.rpm

 

2)它的目录文件

/var/lib/jmxtrans
/var/log/jmxtrans
/etc/rc.d/init.d/jmxtrans
/etc/jmxtrans
/usr/share/jmxtrans
/usr/share/jmxtrans/bin/jmxtrans
/usr/share/jmxtrans/lib/org/jmxtrans
/usr/share/jmxtrans/lib/org/jmxtrans/jmxtrans
/usr/bin/jmxtrans
/run/jmxtrans
/run/lock/subsys/jmxtrans

 

3)编辑zookeeper.json文件并放到/var/lib/jmxtrans/目录

一般我们的Zookeeper是一个集群,比如当我们的Zookeeper为3台的时候,则需要弄三份zookeeper.json文件,每一份对应Zookeeper集群的每一台机器,通过里面的host和port对应

        },
        {

                "username": "admin",

            }],
            "obj": "java.lang:type=Threading",
            "resultAlias": "Threading",
            "attr": ["ThreadCount"]
        }],
        "numQueryThreads": 2
    }]
    }

 

4)启动JMXtrans

启动后,查看日志/var/log/jmxtrans/jmxtrans.log,看是否启动成功,若有错误则根据对应的错误解决就可以

/usr/share/jmxtrans/bin/jmxtrans start

 

4、Grafna上配置数据源

 

当创建Query,选择Influxdb数据源后,若有对应的指标出来,表明是OK的
