zabbix3.0.4利用iostat工具監控centos主機磁盤IO
該監控基於iostat,而後iostat 命令用來監視系統輸入/輸出設備負載ios
1.安裝IOSTAT工具express
# yum install sysstat -y
測試iostat 查看全部硬盤iovim
# 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.部署腳本bash
# 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
添加腳本執行權限
# chmod +x /usr/local/zabbix-agent/scripts/zabbix-iostat.sh
# 設置參數app
# echo 'UserParameter=iostat[*],/usr/local/zabbix-agent/scripts/zabbix-iostat.sh "$1" "$2"' > /etc/zabbix/zabbix_agentd.d/iostat.conf
#重啓zabbix_agentdide
service zabbix-agent restart
# 測試自動發現工具
zabbix_agentd -t iostat[discovery]
3.加入crontaboop
# 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 )
# 重啓計劃任務
/etc/init.d/crond restart
測試監控項性能
# zabbix_agentd -t iostat[vda,rkb/s]
iostat[vda,rkb/s] [t|0.007]測試
