My network I/O Graph is empty. This is the error message from rrd-data.log:

2006-02-09 10:38:19 RRD error updating /users/hobbit4.0//data/rrd/foo.bar/netstat.rrd from 10.100.1.2: expected 11 data source readings (got 16) from 1139477899:U:U:0:3117281:3343088:U:U: U:3836150036:803080985:U:784025:10478468:7420058:U:589:...

All hobbit clients are HP-UX and Linux clients. I have also deleted the netstat.rrd files, so I am sure they recreated by hobbit. They are recreated but not updated. Any ideas?

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.
