I have a Synology RS812RP+ which I'm using for a little bit of departmental testing. I've stuffed a bunch of SSD disks in it, and I'm curious about monitoring the disk IO.

iostat doesn't come pre-installed on the synology and it doesn't have the tools to build it. Does anyone have any advice about getting iostat running in this environment?


You can install dstat as a replacement for iostat

dstat - 0.7.0-1 - dstat is a versatile replacement for vmstat, iostat, netstat, nfsstat, and ifstat

You can install it by using ipkg which allows you to download other tools as well.

Zorlack, I am new to Synology (we just got a DS1812+). Mine is running BusyBox 1.16, and I think it's up-to-date... apparently BusyBox 1.18 has iostat (http://free-electrons.com/blog/busybox118/) so I'm sure you could get it running somehow. I'd poke around the Synology Wiki and maybe ask over at their community wiki. Looks like you're not the only one though, check out http://forum.synology.com/enu/search.php?sid=59a2416beef28ed46b8c6b3068bb74ee

  • I saw that 1.18 has iostat... I think building and installing BusyBox for that environment may be outside my skills. Particularly since there are no compiler tools on the Synology. – Zorlack Jun 5 '12 at 20:14
