First time trying this out, and I have successfully got through the excellent Getting Started instructions. It is working.
Some feedback and a question:
It did seem a bit odd that all the datapoints had the same timestamp. This is seen in the Kibana screenshot too.
As far as I can see, by default the timestamp for each event is the time it was received by logstash, and not the actual timestamp in the logfile.
Is there an example of a logstash configuration file showing how to get the events to use the timestamp from a standard logfile such as Apache?
