How to extract file name from source vairable

HI Team,
I need to extract the source field, when i process im getting grok parse failure please find the belwo image for your reference,

Im using below grok pattern,


That doesn't work because the filename isn't a UUID because it begins with "U" (and ends with "_Request.xml" but is it happens that doesn't matter here).

Use %{PATH}/%{UUID:requestFileId} instead of %{PATH}/U%{UUID:requestFileId} and things should work better.

Its not working, Im getting same error. I want to extract this value also from this input,


Expected Result: 0a5d3ad4-421c-49bd-b05f-c83e869e526f

but im getting parse failure

Its not working, Im getting same error.

With the exact input string you gave in your example or with the file named 0a5d3ad4-421c-49bd-b05f-c83e869e526f_Request.xml?

Actually im processing one xml please find the result of that file,

I want to extract this value "0a5d3ad4-421c-49bd-b05f-c83e869e526f" from source field how can i perform that. Please help on that

Never post screenshots if you can use copy/paste.

I don't know why %{PATH} as in your previous example doesn't work, but the grok expression /%{UUID:requestFileId}_Request.xml$ works fine.

"offset" => 0,

"hostname" => "vmtlesdq01",
"name" => "vmtlesdq01"
"host" => "vmtlesdq01",
"fingerprint" => "18c5809fa1cf7208b25fdfc0052fe997f8af2cb3",
"fields" => nil

This is what i got from grok debugger
