Olly's questions

我已经配置了 logstash (v1.5.0)，带有一个简单的 syslog 输入，如下所示：

input {
  syslog {
    type => syslog
    port => 5514
  }
}

filter {
  kv {}
}

output {
  elasticsearch {
    cluster => "logs"
    host => "0.0.0.0"
    protocol => "transport"
  }
}

但是，它似乎在某些 cron 日志上失败了。以下行无法使用 a 解析_grokparsefailure_sysloginput：

<77>Jul 22 22:01:01 ip-172-31-2-48 run-parts(/etc/cron.hourly)[2599 finished 0yum-hourly.cron

最终的 JSON 输出是：

{
  "_index": "logstash-2015.07.22",
  "_type": "syslog",
  "_id": "AU63yLrC118PBgBqQxRA",
  "_score": null,
  "_source": {
    "message": "<77>Jul 22 22:01:01 ip-172-31-2-48 run-parts(/etc/cron.hourly)[2599 finished 0yum-hourly.cron\n",
    "@version": "1",
    "@timestamp": "2015-07-22T22:01:01.569Z",
    "type": "syslog",
    "host": "172.31.2.48",
    "tags": [
      "_grokparsefailure_sysloginput"
    ],
    "priority": 0,
    "severity": 0,
    "facility": 0,
    "facility_label": "kernel",
    "severity_label": "Emergency"
  },
  "fields": {
    "@timestamp": [
      1437602461569
    ]
  },
  "sort": [
    1437602461569
  ]
}

任何指针？
