Often we want to look at behaviour over time when we change +something, so cumulative statistics are not ideal: we'd like to see a window of data which gradually moves over time. Look at how to implement this with ps_top. I'd expect the window to be rather small, perhaps 1 minute, or maybe longer triggered by collecting data less frequently. -3. vmstat, iostat, pt-diskstats and other such utilities show values +2. vmstat, iostat, pt-diskstats and other such utilities show values over time but providing output as stdout.

Add some replication metrics to pstop as most of my servers are slaves and we want to know where the server is busy. I've seen a way to do that and need to incorporate it into pstop. -5. _if_ ps statistics get truncated it would be good to be able to +4. _if_ ps statistics get truncated it would be good to be able to remember the latest state and add those metrics back again, _if_ looking at absolute rather than relative statistics. On servers I manage I currently truncate info as it is collected after 15-minutes, so this might happen while watching a server with pstop. -6. Improve the options for sorting the data. Total latency is good, +5. Improve the options for sorting the data. Total latency is good, but it would be good to see the write based metrics ordered by total write latency. So look to improve the display and sort options here. -7.
