Hmm, you should see, for example, phys_disk_bytes_sec.
I certainly see that coming from our test environment.
http://ganglia.aprconsulting.ch/?c=unspecified&h=HP1.flasby.org&m=&r=hour&s=descending&hc=4
shows my laptop which I am using to write this, and this metric is near
the bottom.
Possibly you are using a gmond.conf which doesnt report these additional
statistics.
In my setup I have the block below at the end of my gmond.conf which
collects phys_disk_bytes_sec.
Let me know...

Yes, I use your MS Win port of Ganglia.
But I don't see disk I/O related metrics (only disk_total and disk_free
- total and free space on a harddisk)
Rgds,

Hi Vitaly, don't the additional Windows specific metrics
provide what you need in our port?
Or are you no longer using the windows version from us?
Either way I woudl be interested to know...

I noticed that there is no Ganglia disk I/O metrics for Linux and MS
Windows platforms?
Can you recommend me some tools/plugins for collecting IO metrics?
(except of writing a custom scripts around "iostat")
Thanks,
Vitaly

Alice felt dreadfully puzzled. The Hatter's remark seemed to
have no sort of meaning in it, and yet it was certainly English.
`I don't quite understand you,' she said, as politely as she could.
