I checked the default vmstat rrd in hobbit, and a DS for "blocked (b)"
is being collected.  Blocked process indicate IO bound processes.
Crude, but pretty effective.

I am requesting an additional graph in the trends page specifically
for the "b" DS of the vmstat rrd.  This DS might not exist for all
*IX, but for most.

Forgive me if this is configurable, I still picking up the details of
hobbit functionality.

-bash-2.05b$ rrdtool info vmstat.rrd
filename = "vmstat.rrd"
rrd_version = "0003"
step = 300
last_update = 1185291307

..snip..


ds[cpu_b].type = "GAUGE"
ds[cpu_b].minimal_heartbeat = 600
ds[cpu_b].min = 0.0000000000e+00
ds[cpu_b].max = NaN
ds[cpu_b].last_ds = "UNKN"
ds[cpu_b].value = 7.0000000000e+00
ds[cpu_b].unknown_sec = 0
