zookeeper集群常用的监控命令概述
一.监控命令介绍
1.zookeeper常用四字命令简介
zookeeper支持某些特定的四字命令与其的交互。它们大多是查询命令，用来获取zookeeper服务的当前状态及相关信息。用户在客户端可以通过telnet或者nc向zookeeper提交相应的命令。
zookeeper常用四字命令如下所示:
conf:
输出相关服务配置的详细信息。比如端口，zookeeper数据及日志配置路径，最大连接数，session超时时间，serverId等。
ruok:
测试服务是否处于正确运行状态，如果回复的不是"imok"，那就说明该节点挂掉啦！注意观察输出结果哟！
envi:
输出关于服务器的环境变量。
cons:
列出所有连接到这台服务器的客户端连接/会话的详细信息。包括"接收/发送"的包数量，session id，操作延迟，最后的操作执行等信息。
dump:
列出未经处理的会话和临时节点。打印集群的所有会话信息，包括ID，以及临时节点等信息。用在Leader节点上才有效果。
stat:
输出服务器的详细信息，接收/发送包数量，连接数，模式(leader/follower)，节点总数，延迟。所有客户端的列表。
查看统计信息，一般用来查看哪个节点被选择作为follower或者leader。
srvr:
和stat输出信息一样，只不过少了客户端连接信息。
mntr:
输出比stat更为详细的服务器统计信息。列出集群的健康状态。
wchs:
列出服务器watches的简洁信息，如连接总数，watching节点总数和watches总数。
wchc:
通过session分组，列出watch的所有节点，它的输出是一个与watch相关的会话的节点列表。
wchp:
通过路径列出服务器watch的详细信息。它输出一个与session相关的路径。
reqs:
查看未经处理的请求。
crst:
重置当前这台服务器所有连接/会话的统计信息。
srst:
重置server状态。
2.部署命令行工具
[root@elk102.oldboyedu.com ~]# yum -y install nc telnet3.基于telnet查看zookeeper集群的状态信息
[root@elk102.oldboyedu.com ~]# echo conf | nc elk101.oldboyedu.com 2181
clientPort=2181
secureClientPort=-1
dataDir=/yinzhengjie/data/zookeeper/version-2
dataDirSize=805320668
dataLogDir=/yinzhengjie/data/zookeeper/version-2
dataLogSize=805320668
tickTime=2000
maxClientCnxns=60
minSessionTimeout=4000
maxSessionTimeout=40000
clientPortListenBacklog=-1
serverId=101
initLimit=5
syncLimit=2
electionAlg=3
electionPort=3888
quorumPort=2888
peerType=1
membership:
server.101=elk101.oldboyedu.com:2888:3888:observer
server.102=elk102.oldboyedu.com:2888:3888:participant
server.103=elk103.oldboyedu.com:2888:3888:participant
version=0
[root@elk102.oldboyedu.com ~]#
4.基于nc查看zookeeper集群的状态信息
[root@elk102.oldboyedu.com ~]# echo conf | nc elk101.oldboyedu.com 2181
clientPort=2181
secureClientPort=-1
dataDir=/yinzhengjie/data/zookeeper/version-2
dataDirSize=805320668
dataLogDir=/yinzhengjie/data/zookeeper/version-2
dataLogSize=805320668
tickTime=2000
maxClientCnxns=60
minSessionTimeout=4000
maxSessionTimeout=40000
clientPortListenBacklog=-1
serverId=101
initLimit=5
syncLimit=2
electionAlg=3
electionPort=3888
quorumPort=2888
peerType=1
membership:
server.101=elk101.oldboyedu.com:2888:3888:observer
server.102=elk102.oldboyedu.com:2888:3888:participant
server.103=elk103.oldboyedu.com:2888:3888:participant
version=0[root@elk102.oldboyedu.com ~]#
5.可能会遇到的报错: "conf is not executed because it is not in the whitelist."解决方案
如果出现"conf is not executed because it is not in the whitelist."的报错信息，说明咱们的zookeeper集群并没有开启四字命令。
我们需要修改"zoo.cfg"配置文件，并添加"4lw.commands.whitelist=*"这行配置信息即可:
[root@elk101.oldboyedu.com ~]# vim /yinzhengjie/softwares/zookeeper/conf/zoo.cfg
[root@elk101.oldboyedu.com ~]#
[root@elk101.oldboyedu.com ~]# egrep -v "^#|^$" /yinzhengjie/softwares/zookeeper/conf/zoo.cfg
tickTime=2000
initLimit=5
syncLimit=2
dataDir=/yinzhengjie/data/zookeeper
clientPort=2181
clientPortAddress=172.200.1.101
peerType=observer
4lw.commands.whitelist=*
server.101=elk101.oldboyedu.com:2888:3888:observer
server.102=elk102.oldboyedu.com:2888:3888
server.103=elk103.oldboyedu.com:2888:3888
[root@elk101.oldboyedu.com ~]#
[root@elk101.oldboyedu.com ~]# manager-zk.sh restart # 修改以后记得重启服务使之生效!
二.四字监控命令实战案例
1.conf命令(输出相关服务配置的详细信息。)
(1)查看"conf"命令的输出:
[root@elk102.oldboyedu.com ~]# echo conf | nc elk101.oldboyedu.com 2181 | more
clientPort=2181
secureClientPort=-1
dataDir=/yinzhengjie/data/zookeeper/version-2
dataDirSize=805320668
dataLogDir=/yinzhengjie/data/zookeeper/version-2
dataLogSize=805320668
tickTime=2000
maxClientCnxns=60
minSessionTimeout=4000
maxSessionTimeout=40000
clientPortListenBacklog=-1
serverId=101
initLimit=5
syncLimit=2
electionAlg=3
electionPort=3888
quorumPort=2888
peerType=1
membership:
server.101=elk101.oldboyedu.com:2888:3888:observer
server.102=elk102.oldboyedu.com:2888:3888:participant
server.103=elk103.oldboyedu.com:2888:3888:participant
version=0
[root@elk102.oldboyedu.com ~]#
(2)有关"conf"命令的输出说明如下:
clientPort:
对客户端暴露的端口号
secureClientPort:
安全客户端的端口号，若不设置，则默认为-1。
dataDir:
数据快照文件目录，默认情况下10w次事务操作生成一次快照。
dataDirSize:
事务日志文件目录，生产环境中放在独立的磁盘上。
dataLogDir:
事务日志文件目录，生产环境中放在独立的磁盘上。
dataLogSize:
事务日志文件目录，生产环境中放在独立的磁盘上。
tickTime:
客户端与服务器之间维持心跳的时间间隔(以毫秒为单位)。
maxClientCnxns:
最大连接数。
minSessionTimeout:
最小session超时，它默认等于"tickTime * 2"。
maxSessionTimeout=40000
最大session超时，它默认等于"tickTime * 20"。
clientPortListenBacklog:
TCP服务端用于临时存放已完成三次握手的请求的队列的最大长度。
serverId=101
zookeeper服务器对应的server ID编号。
initLimit:
"tickTime * initLimit"决定了ACK的超时时间
syncLimit:
"tickTime * syncLimit"决定了服务端心跳超时时间
electionAlg:
选举算法1和2已被废弃，目前使用的是3。
electionPort:
选举端口，用于Leader选举过程中投票通信。
quorumPort:
用于follow节点和leader节点之间的数据同步和其它通信端口。
peerType:
选项"observer/participant"，决定节点角色。
membership:(集群中的成员)
server.101=elk101.oldboyedu.com:2888:3888:observer
server.102=elk102.oldboyedu.com:2888:3888:participant
server.103=elk103.oldboyedu.com:2888:3888:participant
version:
从名称上来看，该参数应该是zookeeper的版本信息，但其值却是"0"，这一点让我暂时也摸不着头脑。
2.ruok命令(测试服务是否处于正常运行状态，如果回复的不是"imok"，那就说明该节点挂掉啦！注意观察输出结果哟!)
[root@elk102.oldboyedu.com ~]# echo ruok | nc elk101.oldboyedu.com 2181 | more
imok
[root@elk102.oldboyedu.com ~]#
3.envi命令(输出关于服务器的环境变量。)
[root@elk102.oldboyedu.com ~]# echo envi | nc elk101.oldboyedu.com 2181
