Linux host which sents "cpu_wait" works, HPUX doesn't send that. ( I've HPUX, SuSE, Tru64 )

rrdtool dump ../alfpa01/vmstat.rrd |grep name

I've found HPUX clients don't report some elements and this breaks hobbitgraph... so.... use rrdtool dump {hosts rrd vmstat file path] to see what's collected and compare to the hard defs in hobbitgraph.cfg

Hi,

I gave this a try and the vmstat items show up only as objects and not graphs. Part of the host entry is below for this host.

I am sure I am missing something really easy. Any ideas?

TRENDS:*,apache:apache|apache1|apache2|apache3,vmstat:vmstat1|vmstat5

Hi Henrik,

Thanks, it works .. maybe it will be more comprehensive and impressive if it will give graphical I/O stat per filesystem ?

Hi,

the Hobbit mailing list - hobbit at hswn.dk - really is the best place for support questions.

The only I/O measurement built into Hobbit is the data collected from "vmstat", which gives you an overall measure of the amount of time spent waiting for disk I/O. This graph is not displayed by default; you can make them appear on the "trends" page by adding TRENDS:*,vmstat:vmstat1|vmstat5 to each of the host entries in bb-hosts. That will give you a "CPU utilisation" graph that includes the I/O wait time, and a "Block I/O" graph showing the number of blocks read from/written to a disk device.

Regards, Henrik

Is there any scripts in hobbit that monitors disk I/O performance in linux box ? and with graphical presentation ? Can you help me on this since we are now having an issue with disk I/O performance in our Oracle servers ?
