vmstat "b" graph

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
