Being a newbie with Kibana I might be asking about something that is already answered. So, my apologies on beforehand. Anyhow, I cannot find any appropriate entries, so any pointer will be appreciated.
My problem is centrered around the fact that I do have a number of fields with interesting data, extracted from log files produced by the Jetty webserver. Everything looks nice until I attempt to create a line chart; the only fields seemingly available for aggregation are those whose type is 'number', i.e. 'geoip.latitude' and geoip.longitude'.
After scrutinizing the data I found that e.g. the 'duration' field (one of those fields I'd like to chart) to be a string, eventhough the LogStash config tells it to be a number. Also tried INT, but to no avail.
Could you please advise on what I am missing. Checked some of the examples and responses I did find and they all seem to have things like 'Repsonse Time' and 'Duration' available as fields for aggregation ...
My aplogies as I am probably inquiring about something obvious, and thanks in advance.
P.S. did Management -> "Index Patterns" and Refresh and all fields are visible with their types, etc. I can see that there is both a 'duration' and a 'duration.keyword' field - both are strings but the '.keyword' one is aggregatable. How can I force it to be of type 'number' or 'int'? Would that solve the problem?
