例如net.dns.get[,example.com] 监控项可能会返回被拒绝查询的 JSON 如下：

  1. {
  2.            "flags": [
  3.                "RA"
  4.            ],
  5.            "query_time": "0.00",
  6.            "question_section": [
  7.                {
  8.                    "qclass": "IN",

  14.            "zbx_error_code": 0
  15.        }

通过提供DNS服务器的IP地址 net.dns.get[192.0.2.0,example.com] 监控项可能会返回以下JSON:

  1. {
  2.            "answer_section": [
  3.                {
  4.                    "class": "IN",

  31.            "response_code": "NOERROR",
  32.            "zbx_error_code": 0
  33.        }

如果存在连接问题net.dns.get[192.0.2.0,example.com] 监控项可能返回错误:

  1. {
  2.            "zbx_error_code": -1,
  3.            "zbx_error_msg": "Communication error: read udp 192.0.2.0:12345->192.0.2.0:53: i/o timeout"

以下是可能出现的错误码类型:

场景“zabbix错误码”“zabbix错误信息”
没有错误，并且已收到并解析 DNS 响应.0
DNS 已关闭.-1“通信错误”
JSON解析过程中出现错误-2“收到非预期的响应”

通过附加的参数net.dns.get[192.0.2.0,example.com,ANY,5,5,tcp,"cdflag,rdflag,dnssec,nsid,edns0,aaflag,adflag"] 监控项可能返回以下JSON:
