Zabbix3.0.4利用iostat工具監控CentOS主機磁碟IO
該監控基於iostat,然後iostat 命令用來監視系統輸入/輸出裝置負載
1.安裝IOSTAT工具
# yum install sysstat -y
測試iostat 檢視所有硬碟io
# iostat
Linux 2.6.32-431.11.25.el6.ucloud.x86_64 (test8_Hadoop_kaf) 07/27/2017 _x86_64_ (4 CPU)
avg-cpu: %user %nice %system %iowait %steal %idle
0.04 0.00 0.04 0.00 0.00 99.92
Device: tps Blk_read/s Blk_wrtn/s Blk_read Blk_wrtn
vda 0.10 0.23 0.92 447172 1765488
vdb 0.00 0.00 0.15 4298 277632
2.部署指令碼
# mkdir -p /usr/local/zabbix-agent/scripts/
# vim /usr/local/zabbix-agent/scripts/zabbix-iostat.sh
#!/bin/bash
ZBX_DEV="$1"
ZBX_METRIC="$2"
IOSTAT_LOG=/tmp/iostat.log
# Check iostat util
if ! which iostat 2>&1>/dev/null; then
>&2 echo "Can't find 'iostat' binary in \$PATH"
>&2 echo "Make sure that you've installed 'sysstat' package"
exit 1
fi
# Check args
[[ $# -lt 1 ]] && { echo "Give some more arguments, please :)"; exit 1; }
# Discovering devices and spits out JSON
if [ "$ZBX_DEV" = 'discovery' ]; then
iostat -d | \
tail -n +4 |
awk 'BEGIN {
ORS="";
print "{\"data\":["}
/\d/ {printf "%s{\"%s\":\"%s\"}", separator, "{#DEVICENAME}", $1, separator = ","}
END {print "]}" }'
exit 0
fi
# Test iostat log
[[ ! -f "${IOSTAT_LOG}" ]] && echo "[m|ZBX_NOTSUPPORTED] [No such file ${IOSTAT_LOG}]" && exit 1
# Parse iostat file
function parse_iostat() {
grep ${ZBX_DEV} ${IOSTAT_LOG} | \
tr ',' '.' | \
awk -v field="$1" '
{sum+=$field; n++;}
END {if (n > 0) print sum/n;
else {print "[m|ZBX_NOTSUPPORTED] [Nodata.]" > "/dev/stderr"; exit 1};}'
}
# Exec parse funcion with number of column
case ${ZBX_METRIC} in
rrqm/s ) parse_iostat '2';;
wrqm/s ) parse_iostat '3';;
r/r ) parse_iostat '4';;
w/r ) parse_iostat '5';;
rkb/s ) parse_iostat '6';;
wkb/s ) parse_iostat '7';;
avgrq-sz ) parse_iostat '8';;
avgqu-sz ) parse_iostat '9';;
await ) parse_iostat '10';;
r_await ) parse_iostat '11';;
w_await ) parse_iostat '12';;
svctm ) parse_iostat '13';;
util ) parse_iostat '14';;
* ) echo "[m|ZBX_NOTSUPPORTED] [Unsupported item key.]" && exit 1;;
esac
新增指令碼執行許可權
# chmod +x /usr/local/zabbix-agent/scripts/zabbix-iostat.sh
# 設定引數
# echo 'UserParameter=iostat[*],/usr/local/zabbix-agent/scripts/zabbix-iostat.sh "$1" "$2"' > /etc/zabbix/zabbix_agentd.d/iostat.conf
#重啟zabbix_agentd
service zabbix-agent restart
# 測試自動發現
zabbix_agentd -t iostat[discovery]
3.加入crontab
# crontab -e
* * * * * ( sleep 10 && iostat -dxk 1 20 > /tmp/iostat.tmp && mv /tmp/iostat.tmp /tmp/iostat.log )
* * * * * ( sleep 40 && iostat -dxk 1 20 > /tmp/iostat.tmp && mv /tmp/iostat.tmp /tmp/iostat.log )
# 重啟計劃任務
/etc/init.d/crond restart
測試監控項
# zabbix_agentd -t iostat[vda,rkb/s]
iostat[vda,rkb/s] [t|0.007]

<description>Percentage of elapsed time during which I/O requests were issued to the device (bandwidth utilization for the device). Device saturation occurs when this value is close to 100% for devices serving requests serially. But for devices serving requests in parallel, such as RAID arrays and modern SSDs, this number does not reflect their performance limits.
對裝置發出I/O請求的時間的百分比（裝置頻寬利用率）。裝置飽和發生時，這個值是接近100%的裝置服務請求連續。但在平行的服務請求的裝置，如磁碟陣列和現代固態硬碟，這個數字並不反映其效能極限。</description>
