Conky Reporting Disk Operation – How to Separate Read and Write

[Member olsztyn]

Just a question:
Currently Conky as it comes reports measurements of disk operations – Read and Write.
Is it possible to report them as separate measurements – Read and Write separately?
Thanks and Regards…

Try these:

${diskio_read /dev/sda}
${diskio_write /dev/sda}

(from: http://www.ifxgroup.net/conky.htm#p2 ) Tested; they do work.

Thanks again christophe. It looks like works perfectly, especially using graph representation, thanks to your link, which is a great resource.
Now Conky is showing Write I/O separately from Read for drives, which for Live USB it is monitoring writes to flash media antiX performs when using heavy apps, such as Firefox or Chrome with and and without persistence.
Thanks and Regards.

This is so cool. With this, I can track the magnitude of a read or write operation whenever I’m in my Live-usb-storage directory (when
running, say, a live USB with root persistence, or perhaps no persistence at all).

Thanks for the share!

Indeed. Thanks to christophe’s guidance I have been monitoring reads and writes to my Live USB antiX instances. I am running mostly with no persistence as I have completed my composition of software and if any additional happen then I remaster.
Interim results indicate just mostly reads from USB sticks. Hardly any writes and if such occur they are very small, even with multiple tabs of Chrome. I did not have an opportunity to test with Firefox yet, but my general impression is antiX performs very nicely with Live USB flash sticks…

+1 on big thanks to @christophe! This technique debunks my long-time suspicion on antiX or Firefox writing temp files on LiveUSB thus slowing down my 2 gig ram PC when it was running out of memory. Now I know, those slow I/O are all reads, presumably caused by some application content been inevitably evicted from ram, therefore the OS needs to reload it from LiveUSB. antiX is doing the right thing here!
