Question

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：

日志文件：

我使用grok模式来解析这个日志文件，以下是我的示例配置文件：

配置文件：

filter {
        if [type] == "bw5applog" {
        grok {
            match => [ "message", "(?<log_timestamp>%{YEAR}\s%{MONTH}\s%{MONTHDAY}\s%{TIME}:\d{3})\s(?<log_Timezone>%{DATA}\s%{DATA})\s(?<log_MessageTitle>%{DATA})(?<MessageType>%{LOGLEVEL})%{SPACE}\[%{DATA:ProcessName}\]%{SPACE}%{GREEDYDATA:Message}" ]
            add_tag => [ "grokked" ]        
        }
        mutate {
          gsub => [
             "TimeStamp", "\s", "T",
             "TimeStamp", ",", "."
           ]
        }
        if !( "_grokparsefailure" in [tags] ) {
            grok{
                    match => [ "message", "%{GREEDYDATA:StackTrace}" ]
                    add_tag => [ "grokked" ]    
                }
            date {
                    match => [ "timestamp", "yyyy MMM dd HH:mm:ss:SSS" ]
                    target => "TimeStamp"
                    timezone => "UTC"
                }
        }
     }
 }

我可以根据我的要求解析完整的日志条目，但我想格式化日期。

问题陈述：

目前，我从解析的日志条目中获取以下格式的日期：

log_timestamp:  2014·May·28·12:07:35:927

但我的API期望日期的格式如下：

预期输出：

log_timestamp:  2014-05-28T12:07:35:927

如何通过使用上面提到的过滤器配置实现这一点，我尝试使用以下配置做一些事情，但我无法成功。

您正在错误的字段上应用日期过滤器。您必须将timestamp字段应用于log_timestamp字段，而不是date { match => [ "log_timestamp", "yyyy MMM dd HH:mm:ss:SSS" ] target => "log_timestamp" timezone => "UTC" }，该字段包含您要解析的日期：

Timestamp

此外，mutate过滤器没用，因为它应用于不存在的字段（ERROR: for wordpress rpc error: code = 2 desc = "oci runtime error: could not synchronise with container process: mkdir /mnt/sda1/var/lib /docker/aufs/mnt/.../var/www/html/wp-content/uploads: read-only file system"）。

如何在Logstash中的Filter中格式化日期
