Centos 7下通过zabbix监控nfs client的读写性能
操作环境
Centos 7.2
zabbix 3.2
nfs v4
zabbix-server：10.10.200.193
zabbix-agent：10.10.200.227（nfs-client）
我们通过zabbix对10.10.200.227nfs client的读写性能进行监控。
操作说明
1.在nfs-client上配置zabbix agent环境，参照 《Centos 7下搭建Zabbix监控软件》
2.查看nfs-client的目录，并查看mount信息，这个nfs client上面挂载了两个nfs server目录

查看到以上信息后，我们编写以下脚本，在nfs-client上自动获取nfs server的ip地址
[root@ovirt-host-227 ~]# vi /etc/zabbix/zabbix_agentd.d/nfs-find.sh
#!/bin/bash
nfsarray=(`cat /proc/net/nfsfs/servers | sed -n '2,$p' | awk '{print $5}'|sort|uniq 2>/dev/null`)
length=${#nfsarray[@]}
printf "{\n"
printf '\t'"\"data\":["
for ((i=0;i<$length;i++))
do
printf '\n\t\t{'
printf "\"{#NFS_SERVER}\":\"${nfsarray[$i]}\"}"
if [ $i -lt $[$length-1] ];then
printf ','
fi
done
printf "\n\t]\n"
printf "}\n"
授权后，运行进行测试
[root@ovirt-host-227 ~]# /etc/zabbix/zabbix_agentd.d/nfs-find.sh
{
"data":[
{"{#NFS_SERVER}":"10.10.200.193"},
{"{#NFS_SERVER}":"10.10.200.219"}
]
}
完成自动发现nfs-server后，我们通过nfsiostat进行监控nfs-client的nfs读写性能
[root@ovirt-host-227 ~]# nfsiostat 1
10.10.200.193:/home/nfs mounted on /mnt:
op/s rpc bklog
8.96 0.00
read: ops/s kB/s kB/op retrans avg RTT (ms) avg exe (ms)
0.124 30.649 248.164 0 (0.0%) 66.803 66.836
write: ops/s kB/s kB/op retrans avg RTT (ms) avg exe (ms)
8.663 2153.044 248.537 0 (0.0%) 62.286 8964.707
10.10.200.219:/home/nfs3 mounted on /nfs:
op/s rpc bklog
0.02 0.00
read: ops/s kB/s kB/op retrans avg RTT (ms) avg exe (ms)
0.000 0.000 0.000 0 (0.0%) 0.000 0.000
write: ops/s kB/s kB/op retrans avg RTT (ms) avg exe (ms)
0.000 0.000 0.000 0 (0.0%) 0.000 0.000
并将显示信息写入文本
#nfsiostat 1 >> /tmp/nfsper &
添加以下内容至zabbix-agentd.conf配置文件中
UserParameter=nfs.server[*],/etc/zabbix/zabbix_agentd.d/nfs-find.sh $1
UserParameter=nfs.readKBps[*],/usr/bin/tail -18 /tmp/nfsper | grep -A 8 "\b$1\b"|tail -l| awk '{print $$2}' | sed -n '6,1p'
UserParameter=nfs.writeKBps[*],/usr/bin/tail -18 /tmp/nfsper | grep -A 8 "\b$1\b"|tail -l| awk '{print $$2}' | sed -n '8,1p'
重启zabbix-agent
#systemctl restart zabbix-agent
3.在zabbix-server端通过zabbix_get测试是否能获取到nfs-client中定义的参数值
[root@centos7-zabbix-193 home]# zabbix_get -s 10.10.200.227 -k nfs.readKBps[10.10.200.193]
0.000
[root@centos7-zabbix-193 home]# zabbix_get -s 10.10.200.227 -k nfs.writeKBps[10.10.200.193]
0.000
[root@centos7-zabbix-193 home]# zabbix_get -s 10.10.200.227 -k nfs.server
{
"data":[
{"{#NFS_SERVER}":"10.10.200.193"},
{"{#NFS_SERVER}":"10.10.200.219"}
]
}
4.在zabbix web console端创建template NFS CLIENT PERFORMANCE
创建discovery rule
分别创建读写性能的item prototype
创建graph prototype
通过以上步骤就完成了创建Template的步骤，将该Template 添加至Host nfs-client中
添加Template后，查看该host的item
查看graph
点击查看graph
通过以上操作就完成了通过zabbix监控nfs client的全部操作
