Logstash timestamp issue

I have logs which have got time stamp which are in the format 17/01/30 07:55:03

i have got it parsed using Grok filters but when i want to assing the same value to @timestamp it does not turn up.
My filters look like
grok {
patterns_dir => ["/etc/logstash/pattern"]
match => {
"message" => "%{sparktime:logdate} %{LOGLEVEL:loglevel} %{GREEDYDATA:details}"
}
tag_on_failure => []
}
date {
match => ["logdate", "yy/MM/dd HH:mm:ss"]
}

                        grok {
                             match => {
                                    "details" => "%{WORD:class}:  %{WORD}:%{GREEDYDATA:mes} : %{NUMBER:numOfLines:int} logType:%{GREEDYDATA:stage}:%{GREEDYDATA:substage} zipFile:%{GREEDYDATA:zipfile} stgFile:%{GREEDYDATA:textfile}"
                                     }
                            tag_on_failure => []
                            }

Could anyone please advise where am i going wrong. If i use date filter other fields also get disturbed but if i remove date then all parsing work but timestamp does not get assigned to acual log timestamp

What does this mean, exactly? Your configuration looks correct. Please show a message that you think is wrong. Use a stdout { codec => rubydebug } output. If the date filter fails to parse a timestamp the Logstash log will contain clues about what it didn't like.

Hi Magnus

This does produce any logs in my file.
What i meant is the grok filter seems to be working but when i add the date filter it creates problems.
I do not get the fields mentioned in the grok filter but if the remove the date filter part it does produce the fields present in grok filter.
Do i need to change anything to see the output in logs using rubydebug because currently i see error info and warnign messages and none of them has any usefull info.

Show us your configuration and an example input line.

If you're running Logstash in a terminal it should show up in your terminal. If you're running Logstash as a service I think it ends up in logstash.stdout in the log directory.
