"message" =\> "8PRF/abcbcbcbcbcbcbcbcbcO0tlFYQXBl",  
"myName" =\> "abc-a7",  
"tags" =\> [  
[0] "\_grokparsefailure"  
],  
"logtimeStamp" =\> "%{year}-%{month}-%{day} %{hour}:%{minute}:%{second}",  
"hostname" =\> "abc-br-01abcdef",  
"type" =\> "abc",  
"path" =\> "/abc/logs/abc.log.3"

The logtimeStamp is not changed and there is grokparse failure.

Your log file does not contain a date, so grok is never going to match it.

The filter what i mentioned above works. I had 2 patterns of logs hence the grokparse failure was misleading.
