Hi,
There is a walltime field in our logs with the format of hh:mm:ss. What is the best format/way for this field in logstash so that we can have a panel in Kibana to sort these walltime data? Currently the field is stored as string, so the data are sorted in alphabet order instead of numeric order. For example for "86:00:00", "48:30:00", "230:00:00", they should be sorted in the order of "230:00:00" "86:00:00" "48:30:00" in Kibana panel, but now they are sorted as "86:00:00" "48:30:00" "230:00:00".
Thanks for your help.
