Centos 7下通过zabbix监控nfs client的读写性能

来源：互联网发布：中性香水知乎编辑：程序博客网时间：2024/06/05 08:12

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

[root@ovirt-host-227 ~]# dfFilesystem               1K-blocks      Used Available Use% Mounted on/dev/mapper/centos-root   52403200  27339848  25063352  53% /devtmpfs                   3986908         0   3986908   0% /devtmpfs                      3997236         0   3997236   0% /dev/shmtmpfs                      3997236      8956   3988280   1% /runtmpfs                      3997236         0   3997236   0% /sys/fs/cgroup/dev/mapper/centos-home  915094976 212562560 702532416  24% /home/dev/sda1                   508588    159696    348892  32% /boottmpfs                       799448         0    799448   0% /run/user/010.10.200.193:/home/nfs   18348032   5031936  13316096  28% /mnt10.10.200.219:/home/nfs3  14356992   3983360   9644544  30% /nfs[root@ovirt-host-227 ~]# mountsysfs on /sys type sysfs (rw,nosuid,nodev,noexec,relatime)proc on /proc type proc (rw,nosuid,nodev,noexec,relatime)devtmpfs on /dev type devtmpfs (rw,nosuid,size=3986908k,nr_inodes=996727,mode=755)securityfs on /sys/kernel/security type securityfs (rw,nosuid,nodev,noexec,relatime)tmpfs on /dev/shm type tmpfs (rw,nosuid,nodev)devpts on /dev/pts type devpts (rw,nosuid,noexec,relatime,gid=5,mode=620,ptmxmode=000)tmpfs on /run type tmpfs (rw,nosuid,nodev,mode=755)tmpfs on /sys/fs/cgroup type tmpfs (ro,nosuid,nodev,noexec,mode=755)cgroup on /sys/fs/cgroup/systemd type cgroup (rw,nosuid,nodev,noexec,relatime,xattr,release_agent=/usr/lib/systemd/systemd-cgroups-agent,name=systemd)pstore on /sys/fs/pstore type pstore (rw,nosuid,nodev,noexec,relatime)cgroup on /sys/fs/cgroup/devices type cgroup (rw,nosuid,nodev,noexec,relatime,devices)cgroup on /sys/fs/cgroup/cpu,cpuacct type cgroup (rw,nosuid,nodev,noexec,relatime,cpuacct,cpu)cgroup on /sys/fs/cgroup/freezer type cgroup (rw,nosuid,nodev,noexec,relatime,freezer)cgroup on /sys/fs/cgroup/net_cls type cgroup (rw,nosuid,nodev,noexec,relatime,net_cls)cgroup on /sys/fs/cgroup/blkio type cgroup (rw,nosuid,nodev,noexec,relatime,blkio)cgroup on /sys/fs/cgroup/memory type cgroup (rw,nosuid,nodev,noexec,relatime,memory)cgroup on /sys/fs/cgroup/hugetlb type cgroup (rw,nosuid,nodev,noexec,relatime,hugetlb)cgroup on /sys/fs/cgroup/cpuset type cgroup (rw,nosuid,nodev,noexec,relatime,cpuset)cgroup on /sys/fs/cgroup/perf_event type cgroup (rw,nosuid,nodev,noexec,relatime,perf_event)configfs on /sys/kernel/config type configfs (rw,relatime)/dev/mapper/centos-root on / type xfs (rw,relatime,attr2,inode64,noquota)systemd-1 on /proc/sys/fs/binfmt_misc type autofs (rw,relatime,fd=35,pgrp=1,timeout=300,minproto=5,maxproto=5,direct)hugetlbfs on /dev/hugepages type hugetlbfs (rw,relatime)mqueue on /dev/mqueue type mqueue (rw,relatime)debugfs on /sys/kernel/debug type debugfs (rw,relatime)sunrpc on /var/lib/nfs/rpc_pipefs type rpc_pipefs (rw,relatime)nfsd on /proc/fs/nfsd type nfsd (rw,relatime)/dev/mapper/centos-home on /home type xfs (rw,relatime,attr2,inode64,noquota)/dev/sda1 on /boot type xfs (rw,relatime,attr2,inode64,noquota)tmpfs on /run/user/0 type tmpfs (rw,nosuid,nodev,relatime,size=799448k,mode=700)10.10.200.193:/home/nfs on /mnt type nfs4 (rw,relatime,vers=4.0,rsize=524288,wsize=524288,namlen=255,hard,proto=tcp,port=0,timeo=600,retrans=2,sec=sys,clientaddr=10.10.200.227,local_lock=none,addr=10.10.200.193)10.10.200.219:/home/nfs3 on /nfs type nfs4 (rw,relatime,vers=4.0,rsize=524288,wsize=524288,namlen=255,hard,proto=tcp,port=0,timeo=600,retrans=2,sec=sys,clientaddr=10.10.200.227,local_lock=none,addr=10.10.200.219)

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/bashnfsarray=(`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 ','         fidoneprintf  "\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 110.10.200.193:/home/nfs mounted on /mnt:   op/s         rpc bklog   8.96    0.00read:            ops/s             kB/s           kB/op         retrans         avg RTT (ms)    avg exe (ms)                  0.124  30.649 248.164       0 (0.0%)   66.803  66.836write:           ops/s             kB/s           kB/op         retrans         avg RTT (ms)    avg exe (ms)                  8.663 2153.044        248.537       0 (0.0%)   62.286 8964.70710.10.200.219:/home/nfs3 mounted on /nfs:   op/s         rpc bklog   0.02    0.00read:            ops/s             kB/s           kB/op         retrans         avg RTT (ms)    avg exe (ms)                  0.000   0.000   0.000       0 (0.0%)    0.000   0.000write:           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 $1UserParameter=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

上述步骤完成了在zabbix-agent端的操作

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"}        ]}

在zabbix-server端可以正确的获取数值

4.在zabbix web console端创建template NFS CLIENT PERFORMANCE
