We should have some way to approximate how much network traffic is happening
due to replication tasks. To really visualize this it would have to go in a
dashboard. I think this would look something like this:
- Ozone tracks total number of bytes transferred since the last restart
- In the dashboard (Grafana for example) we approximate network traffic over
time by subtracting the current sampled metric value from the last sampled
metric.
- Note that the metric's implementation in Ozone would always append to
the counter, so the values would never decrease unless the cluster is restarted.
- The chart would then look like a step function where each plateau shows
the amount of data transferred between its start and end times
@kerneltime is this the way such a thing is usually implemented? I'm not
sure if we have a standard in other Ozone dashboards for how to chart
continuous events like network traffic.
