我是GROK的新手，我有一个ELK堆栈想将一些CWS / Scansafe日志摄取到该婴儿中。我一直无法获得良好的解析输出。我正在使用http://grokdebug.herokuapp.com/和grokconstructor.appspot.com/do/match，试图获得正确的解析经历了一次地狱。日志为W3C，但由制表符\t分隔。我建立了这种模式，但我无法正确解析多字字段（具有空格）以及空字段（并非每条记录都有每条输出）。任何帮助打破这一点或指出正确方向的帮助将不胜感激。
Here is the pattern:
%{TIMESTAMP_ISO8601:cws_datatime} %{WORD:timezone}\t%{IPV4:c_ip}\t%{NUMBER:x_ss_company_id}\t(%{IPV4:cs_X_Forwarded_For})?(\t%{NOTSPACE:cs_username})?(\t%{WORD:cs_method})?(\t%{WORD:cs_uri_scheme})?(\t%{NOTSPACE:cs_host})?(\t%{NUMBER:cs_uri_port})?(\t%{NOTSPACE:cs_uri_path})?(\t%{DATA:cs_uri_query})?(\t%{DATA:user_agent})?(\t%{DATA:cs_Content_Type})?(\t%{NUMBER:cs_bytes})?(\t%{NUMBER:sc_bytes})?(\t%{NUMBER:sc_status})?(\t%{DATA:sc_Content_Type})?(\t%{IPV4:s_ip})?(\t%{NOTSPACE:x_ss_category})?(\t%{WORD:x_ss_last_rule_name})?(\t%{WORD:x_ss_last_rule_action})?(\t%{WORD:x_ss_block_type})?(\t%{WORD:x_ss_block_value})?\t%{IPV4:x_ss_external_ip}(\t%{NOTSPACE:x_ss_referer_host})?
以下是一些示例日志：
#Fields: datatime c-ip x-ss-company-id cs(X-Forwarded-For) cs-username cs-method cs-uri-scheme cs-host cs-uri-port cs-uri-path cs-uri-query cs(User-Agent) cs(Content-Type) cs-bytes sc-bytes sc-status sc(Content-Type) s-ip x-ss-category x-ss-last-rule-name x-ss-last-rule-action x-ss-block-type x-ss-block-value x-ss-external-ip x-ss-referer-host
