Thanks a lot for your response.
we are executing very basic command to load data -
echo “METRIC VALUE EPOCH” | nc SERVER PORT
When we try giving time(epoch date) before 21(3 weeks) days from current value, we are not able to see the data point in grafana report for that particular metric.
We have the data with us , we would need to load past 6 months data and generate a report on top of it.
Major question here is why we not able to back fill just 3 weeks past data with Command ?
Meawhile, will check play.grafana.org for any new methods of loading or for any clue…
