Hello,

Log:  
2016-05-15 00:00:01,305 [fileUtils.py](http://fileUtils.py)(167): INFO Finished removing hpsp\_msaLogRotate from the system.

I get a grokparsefailure for the following:  
grok { match =\> {"message" =\> "%{TIMESTAMP\_ISO8601:timestamp} %{GREEDYDATA:msg}"}

I even tried grok { match =\> {"message" =\> "%{DATE:timestamp\_d} %{TIME:timestamp\_t} %{GREEDYDATA:msg}"}  
and grok { match =\> {"message" =\> "%{YEAR}-%{MONTHNUM}-%{MONTHDAY} %{HOUR}:%{MINUTE}:%{SECOND} %{GREEDYDATA:msg}"}

All these formats work fine on the grok debugger, but not on my instance of logstash.

Can someone please help me out with it?

Thank you.

Works fine for me:

```nohighlight
$ cat test.config 
input { stdin { } }
output { stdout { codec => rubydebug } }
filter {
  grok {
    match => {
      "message" => "%{TIMESTAMP_ISO8601:timestamp} %{GREEDYDATA:msg}"
    }
  }
}
$ echo '2016-05-15 00:00:01,305 fileUtils.py(167): INFO Finished removing hpsp_msaLogRotate from the system.' | /opt/logstash/bin/logstash -f test.config

My configuration file had a semantic error elsewhere, which was causing the error. It works for me now.

Thanks a lot!
