Hi,

	Cris, as far i know/remember hobbit does always create
netstat.rrd with 16 fields (I put the DS names from rrd/do_netstat.c at
the end of the e-mail). Run the command bellow and compare the output
with the DS name list bellow, if they not the same, probable that the
file was not created by hobbit. 

rrdtool dump ~~hobbit/data/rrd/<you_host_name>/netstat.rrd |grep "<name>"

----------------

	Herink, one think i saw, is that on hobbitd_rrd(8) man pages on
the "COLLECTED DATA" secction, mentiones that for vmstat and netstat
variables is still needed the LARRD bottom-feeders, and as far i
understand this is no longer the case after version 4, becase the rrd
format for these data has changed. Or i'm interpreting this wrong.

----------------
	Regards
	Werner

	Bellow, the DS names for netstat.rrd for hobbit current snapshot,
as far i remember its this way since official version 4 was released.
Maybe someone can comment on this.
