Hi How to write a grok expression for the below log
[2017-03-25T00:00:07,137][WARN ]
match => { "message" => "\[%{TIMESTAMP_ISO8601:timestamp}/]/[%{LOGLEVEL:log-level}\s*\]" }
Is this correct , how to write space in grok ? Thanks
%{SPACE}
is that pattern that matches 0 or more spaces, which is very useful if you don't know (or care!) if there will be a space or not.
