我正在使用Logstash将JSON消息输出到API。我正在从日志文件中读取日志。我的配置工作正常，它还将所有消息发送到API。 以下是示例日志文件：

以下是我的配置文件：

grok {

问题陈述：
配置文件正常运行并将所有日志条目发送到API，但我只想将错误日志发送到API。所以，我想检查“MessageType”，其中我得到的日志级别如果它的值是“ERROR”那么它应该发送消息到API，否则logstash应该丢弃该消息。
答案 0 :(得分：1)
在过滤器部分的logstash配置中，您可以根据if条件使用add标记。并且在输出中添加if语句来检查标记错误是否存在，否则将发送它忽略。
在以下if语句之后：
if [type] == "wso2" {
grok {
match => [ "message", "TID:%{SPACE}\[%{INT:SourceSystemId}\]%{SPACE}\[%{DATA:ProcessName}\]%{SPACE}\[%{TIMESTAMP_ISO8601:TimeStamp}\]%{SPACE}%{LOGLEVEL:MessageType}%{SPACE}{%{JAVACLASS:MessageTitle}}%{SPACE}-%{SPACE}%{GREEDYDATA:Message}" ]
add_tag => [ "grokked" ]
}
mutate {
gsub => [
"TimeStamp", "\s", "T",
"TimeStamp", ",", "."
]
}
}
在过滤器中添加以下语句：
if "grokked" in [tags] {
grok {
match => ["MessageType", "ERROR"]
add_tag => [ "loglevelerror" ]
}
}
然后在您的输出中进行以下更改：
output {
if "loglevelerror" in [tags] {
stdout { }
http {
url => "http://localhost:8086/messages"
http_method => "post"
format => "json"
mapping => ["TimeStamp","%{TimeStamp}","MessageType","%{MessageType}","MessageTitle","%{MessageTitle}","Message","%{log_EventMessage}","SourceSystemId","%{SourceSystemId}","StackTrace","%{log_StackTrace}"]
}
}
}
我使用stdout在我的机器上测试了它。它工作正常。希望它有所帮助！
