自动发现规则监控项

脚本，获取监控项取值列表对应的json格式
vim /etc/zabbix/scripts/ceph_proc_discovery.sh

#!/bin/bash

CEPH_PROC_NAMES=($(ps -ef |awk '/\/usr\/bin\/ceph.*|\/usr\/bin\/tcmu-runner/{print $8}' |awk -F "/" '{print $NF}' |sort -u))
CEPH_PROC_NAME=($(ps -ef |awk '/\/usr\/bin\/rbd-target.*/{print $NF}' |awk -F "/" '{print $NF}' |sort -u))

CEPH_PROC_NAMES+=(${CEPH_PROC_NAME[@]})
#echo ${CEPH_PROC_NAMES[@]}
CEPH_PROC_discovery () {
    
    
  printf '{\n'
  printf '\t"data": [\n'
  for((i=0;i<${#CEPH_PROC_NAMES[@]};i++));do
    num=$((${#CEPH_PROC_NAMES[@]}-1))
    #echo $num
    if [ $i -ne $num ];then
      printf "\t\t{\"{#CEPHNAME}\": \"${CEPH_PROC_NAMES[$i]}\"},\n"
    else
      printf "\t\t{\"{#CEPHNAME}\": \"${CEPH_PROC_NAMES[$i]}\"}\n"
    #echo ${CEPH_PROC_NAMES[$i]}
    fi
  done

  printf '\n]}'

}
