A line from my logfile:

63001,MAt,1420396131,20-SEP-11 12.12.38.000000 AM,RecordSource,null,Can not be null,null

I want to convert --\> 20-SEP-11 12.12.38.000000 AM into date time format and put it into @timestamp field.

Currently I am using this code, and name of my 4th column is "Date"

date {  
match =\> ["Date", "dd-MMM-YY HH.mm.ss.SSSSS"]  
target =\> "@timestamp"

}

and I get the following message:

{  
"message" =\> "299001,MAt,1322737460,20-SEP-11 02.25.45.000000 PM,ClassificationType,null,Can not be null,null",  
"@version" =\> "1",  
"@timestamp" =\> "2016-05-26T23:41:55.767Z",  
"path" =\> "/Users/paritp/Desktop/SampleErrors.txt",  
"host" =\> "[685b358426d6.ant.amazon.com](http://685b358426d6.ant.amazon.com)",  
"type" =\> "core2",  
"ID KEY" =\> 299001,  
"Client ID" =\> "MAt",  
"Account ID" =\> 1322737460,  
"Date" =\> "20-SEP-11 02.25.45.000000 PM",  
"Error Field Name" =\> "ClassificationType",  
"Error Field Value" =\> "null",  
"Error Message" =\> "Can not be null",  
"Record Source" =\> "null",  
"tags" =\> [  
[0] "\_dateparsefailure"  
]  
}

Please help.

This is my config file

input {

type =\> "core2"  
start\_position =\> "beginning"  
ignore\_older =\> 0

}  
filter {

csv {  
separator =\> ","  
columns =\> ["ID KEY","Client ID","Account ID","Date","Error Field Name","Error Field Value","Error Message", "Record Source"]  
autogenerate\_column\_names =\> false

```
  convert => {"ID KEY" => "integer"}
  convert => {"Account ID" => "integer"}
  convert => {"Date" => "date_time"}

```

}

date {  
match =\> ["Date", "dd-MMM-YY HH.mm.ss.SSSSSS"]  
remove\_field =\> "Date"

}

}

output {  
elasticsearch {  
action =\> "index"  
hosts =\> "localhost"  
index =\> "samperror"  
workers =\> 1  
}  
stdout {

You're ignoring that it's a 12-hour time. You should try "hh.mm.ss.SSSSSS a" or maybe "KK.mm.ss.SSSSSS a".

The uppercase month name might also be a problem. IIRC the date filter (actually the Joda-Time library) is annoyingly case-sensitive.
