ok

错误位置:
output {
        if [response_time] >= 5  {
          zabbix {
                zabbix_host => "[@metadata][zabbix_host]"
                zabbix_key => "[@metadata][zabbix_key]"
        zabbix_server_host => "192.168.32.55"
        zabbix_server_port => "10051"
                zabbix_value => "messager"
        }
		
意思是字符串和数值型比较 报错,可能原因是匹配失败
