Logstash Grok pattern GREEDYDATA does not match

Hello there

I'm currently building a pipeline with different grok patterns. For the most part it's properly working already but I'm having issues with some Jira logs:

Log Message:
2018-11-21 12:50:23,950 http-nio-8080-exec-4 INFO anonymous 769x323x1 1hhvqv1 10.195.161.19 /secure/SetupLicense.jspa [c.a.j.p.devstatus.upgrade.UpgradeTask_Build02] Running Upgrade task to add searcher for development field.

Grok Pattern:
(?%{YEAR}-%{MONTHNUM}-%{MONTHDAY}%{SPACE}%{TIME}) %{JIRA_THREAD:thread} %{WORD:loglevel} %{WORD:user} %{JIRA_HTTP_ID:http_request_id} %{JIRA_HTTP_ID:http_session_id} %{IP:ip} %{UNIXPATH:path} %{JIRA_CLASS:class} %{GREEDYDATA:message}

Custom Patterns:
JIRA_THREAD [A-Za-z0-9-/:]+
JIRA_HTTP_ID [A-Za-z0-9-]+
JIRA_CLASS [A-Za-z0-9.]+

The GREEDYDATA:message part doesn't match and I don't understand why. I've checked it with the inbuilt Kibana grok debugger. Can someone please explain this behavior to me?

Thanks in advance!

What does the result look like?

The grok debugger output? It's empty and the error is: "Provided Grok patterns do not match data in the input"

Try this:

%{TIMESTAMP_ISO8601:date} %{JIRA_THREAD:thread} %{WORD:loglevel} %{WORD:user} %{JIRA_HTTP_ID:http_request_id} %{JIRA_HTTP_ID:http_session_id} %{IP:ip} %{URIPATH:path} %{JIRA_CLASS:class} %{GREEDYDATA:message}

Custom pattern:

JIRA_THREAD %{WORD}-%{WORD}-%{INT}-%{WORD}-%{INT}
JIRA_HTTP_ID [A-Za-z0-9-]+
JIRA_CLASS [A-Za-z0-9.\[\]_]+

Oh, I missed the underscore in the JIRA_CLASS pattern. Thank you for the fast help!
