Hi Lonnie
Its a great IaaS solution. Here is a good explanation from one of our cloud
providers https://www.serversaustralia.com.au/products/virtual-data-centre
Thanks for the info here. Yes htop is nice. I only have 1.4 in build so not
much disk traffic so will need to check later. From what I saw in our build
environment I think we will be fine.
Regards
Michael Knill

Hi Michael,
Out of curiosity, what do you mean by "Virtual DC" ? I'm not familiar with
that term.
If you are using AstLinux 1.4.3 or later, the kernel /proc/[pid]/io stats
are enabled.
So, look for "read_bytes" and "write_bytes" in the output of the 'init'
process:
--
cat /proc/1/io
--
For Asterisk, this should work:
--
cat /proc/$(pgrep -f '^asterisk')/io
--
See how quickly "read_bytes" and "write_bytes" increase over a set period
of time. Next convert into IOP by guessing an average block size.
Note: some of this Disk IO is to RAM based tmpfs, but would give you a
worst case scenario.
Additionally, 'htop' supports IO_RATE column (DISK R/W) that can monitor IO.

the Astlinux architecture was still pretty light on in regards to disk writes.
