Apologies if this is more aimed towards LogStash.
I have used LogStash to push data to Kibana from a CSV file.
This has so far been successful, my only issue atm is I now want to create a dashboard to view my data, the main data I need to calculate is a Call Duration field. This is in the format HH:MM:SS.
Unfortunately when it pushes this field to Kibana it marks it as a string so I cannot do any calculation on this.
Any help is greatly appreciated.
