I have the below in my logs  
"2019-07-09\t07:35:42.210\t0.193\t0\tGET\t{URI}\t304\t{ECID}\t{someId}\t-\t{ip address}

I am not able to figure out how should i frame my filter using GROK.

I tried with something like the below:

filter {  
grok{  
match=\>{"message" =\> "%{YEAR}-%{MONTHNUM}-%{MONTHDAY}\t%{HOUR}:%{MINUTE}:%{SECOND}(.[0-9])%{GREEDYDATA:message}"}  
}  
}

Please let me know what i am doing wrong, getting erroo 'grokParseFailure'.  
I am new to Logstash.

Your help will be highly appreciated.

Thanks  
Subrat.

If your message is tab separated the use \s in the grok pattern to match it, not \t.
