Amitav, When you say total volume, do you want a topic’s size on disk, taking into account replication and retention, or do you want the aggregate bytes published into a topic? If you have a metrics collector and a graphing tool such as grafana, you can transform the rate metrics to a byte sum by applying an integral function, but those will always grow and not take into account deletion after the retention period.
If you want metrics on how much space a topic occupies on disk, I’d suggest using collectd and this plugin: https://github.com/HubSpot/collectd-kafka-disk — Peter > On Jan 16, 2019, at 1:12 PM, Amitav Mohanty <[email protected]> wrote: > > Hi > > I am interested in getting total volume of data that a topic ingested in a > period of time.
