Right now host load is "low". I remember a lot of times in the past it was "medium". I usually don't look for that information, so I don't really know the usual host load...
I just realized, it would be great if Linode could show also a "host CPU graph" like the current "My CPU graph" (with 30 days history...), wouldn't it?

Caker?
Apart from that information, I have a little script that sends a lot of stuff to me every 5 minutes. It shows figures from inside my linode, but maybe it can help.
Commands logged (I run two more commands but they are not relevant for this matter):
Code:
cat /proc/io_status
cat /proc/loadavg
vmstat
free -m
cat /proc/meminfo

I can see load average goes down (like from 0.58 0.57 0.54 4/83 7800 to 0.04 0.06 0.03 5/81 14873). I suppose this means that the processes run faster, so they don't use as much CPU as they used to.
But I don't know the reason. AFAIR, there has been no significant change in the running services/programs inside the linode between these two dates. I suspect the hardware has been significantly changed between old host22 and new host70 - maybe faster CPU and faster HD?
I'm not a Linux expert, so any discussion on these figures is very welcome

Also, if there are some interesting stats that I could gather within my little cron script let me know. Thx!
