zabbix监控图形界面（小水玩转监控---Zabbix监控磁盘io之一）

zabbix监控图形界面（小水玩转监控---Zabbix监控磁盘io之一）#!/usr/bin/perl # Zabbix 2 - disk autodiscovery for linux # all disks listed in /proc/diskstats are returned # special processing on LVMs # special processing on Proxmox VE disks (VM id and VM name are returned) # rq : in Zabbix create a regexp filter on which disks you want to monitor on your IT System # ex : ^(hd[a-z] |sd[a-z] |vd[a-z] |dm-[0-9] |drbd[0-9] )$ # ^(loop[0-9] |sr[0-9]*|fd[0-9]*)$

1.拷贝脚本(discover_disk.pl在末尾)至zabbix安装目录的bin目录下(/main/server/zabbix/bin/)并赋予权限

chmod x /main/server/zabbix/bin/discover_disk.pl chown zabbix.zabbix /main/server/zabbix/bin/discover_disk.pl #脚本运行需要perl，若没有安装则使用yum安装 yum install perl -y

2.设置agentd

拷贝以下内容至zabbix_agentd.conf末尾，重启zabbix_agentd # diskio discovery UserParameter=discovery.disks.iostats /main/server/zabbix/bin/discover_disk.pl #读扇区的次数 UserParameter=custom.vfs.dev.read.sectors[*] cat /proc/diskstats | grep $1 | head -1 | awk '{print $$6}' #写扇区次数 UserParameter=custom.vfs.dev.write.sectors[*] cat /proc/diskstats | grep $1 | head -1 | awk '{print $$10}' #合并读完成次数 UserParameter=custom.vfs.dev.read.ops[*] cat /proc/diskstats | grep $1 | head -1 |awk '{print $$4}' #合并写完成次数 UserParameter=custom.vfs.dev.write.ops[*] cat /proc/diskstats | grep $1 | head -1 | awk '{print $$8}' #读花费的毫秒数 UserParameter=custom.vfs.dev.read.ms[*] cat /proc/diskstats | grep $1 | head -1 | awk '{print $$7}' #写操作花费的毫秒数 UserParameter=custom.vfs.dev.write.ms[*] cat /proc/diskstats | grep $1 | head -1 | awk '{print $$11}'

3.导入模板

在zabbix web界面导入模版zbx_export_templates.xml

#模板下载

zbx_export_templates(http://image.wohenniucha.com/upload/2018/05/zbx_export_templates.xml)

#给主机添加该模板即可

4.附脚本discover_disk.pl

#!/usr/bin/perl # Zabbix 2 - disk autodiscovery for linux # all disks listed in /proc/diskstats are returned # special processing on LVMs # special processing on Proxmox VE disks (VM id and VM name are returned) # rq : in Zabbix create a regexp filter on which disks you want to monitor on your IT System # ex : ^(hd[a-z] |sd[a-z] |vd[a-z] |dm-[0-9] |drbd[0-9] )$ # ^(loop[0-9] |sr[0-9]*|fd[0-9]*)$ # Custom keys : #UserParameter=custom.vfs.dev.read.ops[*] cat /proc/diskstats | grep "$1" | head -1 | awk '{print $$4}' #UserParameter=custom.vfs.dev.read.ms[*] cat /proc/diskstats | grep "$1" | head -1 | awk '{print $$7}' #UserParameter=custom.vfs.dev.write.ops[*] cat /proc/diskstats | grep "$1" | head -1 | awk '{print $$8}' #UserParameter=custom.vfs.dev.write.ms[*] cat /proc/diskstats | grep "$1" | head -1 | awk '{print $$11}' #UserParameter=custom.vfs.dev.io.active[*] cat /proc/diskstats | grep "$1" | head -1 | awk '{print $$12}' #UserParameter=custom.vfs.dev.io.ms[*] cat /proc/diskstats | grep "$1" | head -1 | awk '{print $$13}' #UserParameter=custom.vfs.dev.read.sectors[*] cat /proc/diskstats | grep "$1" | head -1 | awk '{print $$6}' #UserParameter=custom.vfs.dev.write.sectors[*] cat /proc/diskstats | grep "$1" | head -1 | awk '{print $$10}' # Discovery items creation : #Disk {#VMNAME}:{#DMNAME} io spent custom.vfs.dev.io.ms[{#DISK}] #Disk {#VMNAME}:{#DMNAME} read bw custom.vfs.dev.read.sectors[{#DISK}] #Disk {#VMNAME}:{#DMNAME} read io custom.vfs.dev.read.ops[{#DEV}] #Disk {#VMNAME}:{#DMNAME} write bw custom.vfs.dev.write.sectors[{#DISK}] #Disk {#VMNAME}:{#DMNAME} write io custom.vfs.dev.write.ops[{#DEV}] # give disk dmname returns Proxmox VM name sub get_vmname_by_id { $vmname=`cat /etc/qemu-server/$_[0].conf | grep name | cut -d \: -f 2`; $vmname =~ s/^\s //; #remove leading spaces $vmname =~ s/\s $//; #remove trailing spaces return $vmname } $first = 1; print "{\n"; print "\t\"data\":[\n\n"; for (`cat /proc/diskstats`) { ($major $minor $disk) = m/^\s*([0-9] )\s ([0-9] )\s (\S )\s.*$/; $dmnamefile = "/sys/dev/block/$major:$minor/dm/name"; $vmid= ""; $vmname = ""; $dmname = $disk; $diskdev = "/dev/$disk"; # DM name if (-e $dmnamefile) { $dmname = `cat $dmnamefile`; $dmname =~ s/\n$//; #remove trailing \n $diskdev = "/dev/mapper/$dmname"; # VM name and ID if ($dmname =~ m/^.*--([0-9] )--.*$/) { $vmid = $1; #$vmname = get_vmname_by_id($vmid); } } #print("$major $minor $disk $diskdev $dmname $vmid $vmname \n"); print "\t \n" if not $first; $first = 0; print "\t{\n"; print "\t\t\"{#DISK}\":\"$disk\" \n"; print "\t\t\"{#DISKDEV}\":\"$diskdev\" \n"; print "\t\t\"{#DMNAME}\":\"$dmname\" \n"; print "\t\t\"{#VMNAME}\":\"$vmname\" \n"; print "\t\t\"{#VMID}\":\"$vmid\"\n"; print "\t}\n"; } print "\n\t]\n"; print "}\n";
