>我有一个 RabbitMQ 发送 3 个 JSON 格式的字段,它被 Logstash rabbitmq 输入插件使用。
其中一个字段是字符串的 JSON 数组,如下所示:
"content": [
"1111",
"2222222",
"Test 06",
"3",
"3232",
"SomeValue1"
]
如何将该字符串的每个条目都放入一个字段中,以便我可以在 Kibana 中快速发现可用字段并进行可视化?现在我看到带有完整字符串的"内容"。
JSON 数组字符串大小根据另一个字段 eventID 而变化。是否可以根据事件 ID 将该字符串中的值动态映射到特定名称? 如:
"eventID": 1, "content": [ "name1": "1111", "name2": "2222222", "name3": "Test 06", "name4": "3", "name5": "3232", "name6": "SomeValue1" ] "eventID": 2, "content": [ "othername1": "3434", "othername2": "Test 10", "othername3": "876", "othername4": "Some String7" ]
我想在可用字段中包含名称*和其他名称*。 任何帮助将不胜感激。
首先,我将暂时假设您的输入已经正确解析为数组。 出于测试目的,这意味着:
echo '{"eventID":1,"content":["a","b","c","d"]}' | bin/logstash -f test.conf
其中 test.conf 是:
input {
stdin { codec => json }
}
output {
stdout { codec => rubydebug }
}
将输出以下内容:
{
"eventID" => 1,
"@timestamp" => 2017-08-03T19:39:13.054Z,
"@version" => "1",
"host" => "xxxxxx.local",
"content" => [
[0] "a",
[1] "b",
[2] "c",
[3] "d"
]
}
如果是这种情况,那么您需要执行以下操作:
filter {
if [eventID] == 1 {
mutate {
add_field => {
"eventName" => "type1 event"
"one0" => "%{[content][0]}"
"one1" => "%{[content][1]}"
"one2" => "%{[content][2]}"
"one3" => "%{[content][3]}"
}
remove_field => [ "content" ]
}
} else if [eventID] == 2 {
mutate {
add_field => {
"eventName" => "type2 event"
"two0" => "%{[content][0]}"
"two1" => "%{[content][1]}"
"two2" => "%{[content][2]}"
"two3" => "%{[content][3]}"
}
remove_field => [ "content" ]
}
}
}
这将生成如下事件:
{
"eventID" => 1,
"@timestamp" => 2017-08-03T19:51:02.946Z,
"@version" => "1",
"host" => "xxxxxxx.local",
"one2" => "c",
"eventName" => "type1 event",
"one3" => "d",
"one0" => "a",
"one1" => "b"
}
