I'm trying to handle an nginx access log in logstash.
In order to get millisecond accuracy for my timestamps, I'm using the
$msec variable. This means that timestamps will be of the form
1430832725.814, where the integer part is a UNIX timestamp, and the fraction part is in milliseconds. Unfortunately, I can't find a logstash date format which can parse UNIX timestamps.
Is there another way to get nginx to log with millisecond accuracy? Or a way to get the logstash date filter to parse UNIX timestamps?
