日志跟踪不显示数据

Question

我有群与麋鹿堆栈，与自定义容器的Kibana与日志。当我打开它时，我可以在Kibana中看到日志，但在Logtrail插件中看不到。我始终没有找到任何事件消息。

我的配置如下所示(用于测试目的)

{
    "index_patterns" : [
        {
            "es": {
                "default_index": "logstash-*",
                "allow_url_parameter": false
            },
            "tail_interval_in_seconds": 5,
            "max_buckets": 500,
            "nested_objects" : false,
            "display_timezone": "local",
            "default_time_range_in_days" : 0,
            "max_hosts": 10,
            "display_timestamp_format": "MM-dd HH:mm:ss.fff",
            "fields" : {
                "mapping" : {
                    "timestamp" : "@timestamp",
                    "display_timestamp" : "@timestamp",
                    "hostname" : "message",
                    "program": "message",
                    "message": "message"
                }
            }
        }
    ]
}

我的日志条目在Kibana中可见：

  "_index": "logstash-2017.06.27",
  "_type": "logs",
  "_id": "AVzrfuXhrXfjBRR51Pyo",

  },

      1498599581137
    ]
  },
  "sort": [
    1498599581137
  ]
}

请问问题出在哪里？

Answer 1

我在您的JSON文件中看不到这一行：

 "message_format":"{{{syslog_message}}}"

您应该能够在现有行中使用{fieldname}向其中添加字段。

一些参考页面：

here和here。

有一次，我有自己的自定义message_format设置，但找不到它告诉我如何格式化它的页面的引用。

编辑：

而且看起来你需要正确地映射你的字段。下面是我在json文件中的失物招领索引：

{
  "index_patterns" : [
    {
      "es": {
        "default_index": "lnf-*",
        "allow_url_parameter": false
      },
      "tail_interval_in_seconds": 10,
      "es_index_time_offset_in_seconds": 0,
      "display_timezone": "local",
      "display_timestamp_format": "MMM DD HH:mm:ss",
      "max_buckets": 500,
      "default_time_range_in_days" : 0,
      "max_hosts": 100,
      "max_events_to_keep_in_viewer": 5000,
      "fields" : {
        "mapping" : {
            "timestamp" : "@timestamp",
            "display_timestamp" : "@timestamp",
            "hostname" : "logsource",
            "program": "program",
            "message": "message"
        },
        "message_format": "{{{message}}}"
      }
    }
  ]
}

请注意，在每个字段映射中都有'message‘...
