Zabbix低级自动发现脚本

1) zabbix_discovery.sh

#!/bin/bash
# 低级自动发现脚本生成固定的zabbix规定的格式

ret=`ss -atunp | grep -i listen | awk -F '[\"\\\( \t\\\)]+' '{print $8}' | sort -nr | uniq`
process=($ret)

printf '{'
printf '"data":['
# echo ${#process[@]}
for index in ${!process[@]}
do
if [[ ${#process[@]} -gt 1 && $index -ne $((${#process[@]}-1)) ]];then
    printf '{'
    printf "\"{#PROCESS}\": \"${process[$index]}\"}," 
else [[ $index -eq $((${#process[@]}-1)) ]]
    printf '{'
    printf "\"{#PROCESS}\": \"${process[$index]}\"}"
fi
done
printf ']'
printf "}\n"

2) zabbix自定义监控项

UserParameter=process_discovery,sudo /xxx/zabbix_discovery.sh 

UserParameter=process_cpu_usage[*],sudo  ps -eo   %cpu,comm | grep $1 | awk '{x[$$2]=+$$1}END{for(i in x){print x[i]}}'
UserParameter=process_mem_usage[*],sudo  ps -eo   %mem,comm | grep $1 | awk '{x[$$2]=+$$1}END{for(i in x){print x[i]}}'
