zabbix监控之进程自动发现

Posted 2020-07-10

1，配置要监控的进程标识

vim processlist.sh

cat /dev/null >/tmp/processlist.txt

if [ `ps aux|grep "apache-tomcat-7.0.56-59002/temp"|grep -v grep |wc -l` -gt 0 ];then echo "apache-tomcat-7.0.56-59002/temp" >>/tmp/processlist.txt;fi

if [ `ps aux|grep "zoo.cfg"|grep -v grep |wc -l` -gt 0 ];then echo "zoo.cfg" >>/tmp/processlist.txt;fi

2，配置自动发现脚本

vim pro_dis.sh

#!/bin/bash

COUNT=`cat /tmp/pro.txt|wc -l`

INDEX=0

echo ‘{"data":[‘

cat /tmp/pro.txt | while read LINE; do

    echo -n ‘{"{#TABLENAME}":"‘$LINE‘"}‘

    INDEX=`expr $INDEX + 1`

    if [ $INDEX -lt $COUNT ]; then

        echo ‘,‘

    fi

done

echo ‘]}‘

3，配置数据脚本

vim process.sh

#!/bin/bash

process=$1

name=$2

case $2 in

cpu)

cat /tmp/ps.txt |grep $process |awk ‘{print $3}‘

;;

mem)

cat /tmp/ps.txt |grep $process |awk ‘{print $4}‘

;;

rss)

cat /tmp/ps.txt |grep $process |awk ‘{print $6}‘

;;

count)

cat /tmp/ps.txt |grep $process |wc -l

;;

*)

echo "Error input:"

;;

esac

exit 0

4，添加到crontab

*/1 * * * * ps aux > /tmp/ps.txt 2>/dev/null

* 23 * * * sh /etc/zabbix/scripts/processlist.sh 2>/dev/null

自动添加crontab

cat cron.sh

#!/bin/sh
PROGRAM="ps aux"
CRONTAB_CMD="*/1 * * * * $PROGRAM > /tmp/ps.txt 2>/dev/null"
(crontab -l 2>/dev/null | grep -Fv "$PROGRAM"; echo "$CRONTAB_CMD") | crontab -
COUNT=`crontab -l | grep "$PROGRAM" |wc -l`
if [ $COUNT -lt 1 ]; then
        echo "fail to add crontab $PROGRAM"

        exit 1

fi

5，配置process_discovery.conf文件

cat /etc/zabbix/zabbix_agentd.d/process_discovery.conf
#ps process
UserParameter=process.discovery,/etc/zabbix/scripts/process_discovery.sh
UserParameter=process[*],/etc/zabbix/scripts/processmonitor.sh \$1 \$2
