Hi,
I am using metricbeat to collect haproxy stats. It seems metricbeat does not calculate delta for cumulative fields like (haproxy.stats.in.bytes and haproxy.stats.out.bytes). Is there any way to calculate the delta value. I have tried writing logstash filter to caculate delta but I am unable to make it working properly.
The reason why I need delta value is to find out the total volume of upload and download per day, week and month.
Example:-
Daily graph showing total sum of volume of upload and download when we choose daily in kibana. same for Mothly and weekly.
