I'm catching up logs, but when they arrived to my Graylog, they take the actual date and not the old date.
I saw my logs and they don't have format date. They're csv, and I have this field :
and I need to assign it on the timestamp, but I don't kno how.
Could you help me please to convert this on a good format?
I tried this (I have a field called: FW_date_time on my source csv file):
Exec $EventReceivedTime =strptime($FW_date_time, '%Y %b %d %T');
Exec $EventTime =strptime($FW_date_time, '%Y %b %d %T');
But it didn't work.
Thank you very much for your help.
