zabbix监控之进程自动发现

Posted 2020-07-09 Tank

1，获取要监控的进程到/tmp/process_list.txt文件

cat process_list.sh

#!/bin/bash
cat /dev/null >/tmp/process_list.txt
if [ `ps aux|grep "/data/apache_projects/tomcat7-express-18034"|grep -v grep |wc -l` -gt 0 ];then echo "/data/apache_projects/tomcat7-express-18034" >>/tmp/process_list.txt;fi
if [ `ps aux|grep "/usr/local/webserver/tengine/sbin/nginx"|grep -v grep |wc -l` -gt 0 ];then echo "/usr/local/webserver/tengine/sbin/nginx" >>/tmp/process_list.txt;fi
if [ `ps aux|grep "/usr/local/mysql/bin/mysqld"|grep -v grep |wc -l` -gt 0 ];then echo "/usr/local/mysql/bin/mysqld" >>/tmp/process_list.txt;fi

 

2，配置自动发现脚本

cat process_discovery.sh

#!/bin/bash
COUNT=`cat /tmp/process_list.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

cat process_monitor.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/process_list.sh 2>/dev/null

 

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/process_monitor.sh $1 $2
