Ubuntu Server: Read vs Write Activity Comparison?

ru flag

I run an instance of Ubuntu Server 20.04.3. What is the best method to check which operation the disks in RAID do more in relation to each other? Read and Write? Like Writes - 80%, Reads - 20%.

You can [install and] run iotop,

sudo apt update
sudo apt install iotop

I often run the following command,

sudo iotop -od2
ru flag
This kind of helps, but tells the info for the very moment when it is happening, not overall. iotop is not new to me, anyway.

@lion, Have a second look at the manual, `man iotop`. There is batch mode and accumulated and timestamp, and you can set long intervals between printouts.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
