I regret neither Top neither Htop show you estimates of "IO Activity time" like in Windows 10 task manager - I need to use separate iostat to observe that.
I found the "IO Activity time", percentage of time when IO is used, to be a really good indicator of IO load on machine level - neither io-op per second, neither bandwith tell much if you're already using up all available IO. Load does not help here, as number of processes doing IO influences "load" more.
- swiley 7y agoTo be fair it’s a far worse problem on Windows (although I guess a lot of my Linux machines are running from ram now so maybe I wouldn’t notice if it weren’t.)
- microcolonel 7y agoOn Linux, that information is privileged, IIRC. so since most people use htop as an ordinary user, they wouldn't see that anyway.
- aljarry 7y agoYeah, you need root or sudo to view iotop. But some information is (at least on some fresh ubuntu) available without elevation, like the per-disk output from iostat.
- lma21 7y agopidstat is also good at showing IO Activity, per process.
- zymhan 7y agoI'm a fan of iotop for monitoring various IO stats in a top-like interface.
- Avamander 7y agoYou also need something like `nethogs` to view network IO, I wish there were a colored, htop-like utility for that as well.
- ajryan 7y agoWhere exactly can I find this in Windows' Task Manager? I don't see it as a column on the Details pane...
- aljarry 7y agoIt's either on Performance tab (per disk) - the big chart is "active time", either per process on Processes tab as a column "Disk" - color is related to time usage, while the bandwidth is as text.
- trasz 7y agoIn FreeBSD top(1) does show the IO statistics - just press “m”.
