D'oh!
Give me a second.

 Looks good, but I think you forgot the hobbitgraph.cfg lines
It can't work without them, could it?

Have fun. :-)
If it shows up on an iostat -xn then it should do the job.

 I got the iostat trend graphs working now :-)
My approach is a bit rough though, I bet yours is better.
Will it take care of metadevices? /dev/global cluster disks? /dev/did
disks?

About to post to Xymonton.
Will update you once done.

Hi,

I'm trying to do the same (for solaris)
By default the code is there on the client, but the server lacks the code
to create the rrd file.
The data is there on the server.
This command shows me that the data is actually received by the server.
xymonserver % $BB $BBDISP 'clientlog server0 section=iostatdisk'
in hobbitd/rrd/do_iostat.c there is a do_iostatdisk_rrd function.
but it isn't in hobbitd/do_rrd.c
I'm not any good at C so I can just see it lacks some coding.
The correct approach would be to fix the source so it includes and
creates the iostatdisk rrd's and trend graphs will just work.

Until next version I tried to fix it.
I've tried to modify Stef Coenes iostat script but I can't get any data
into the rrd file, it is just empty. (NaN)
The graphs on the trends page is there but shows nothing.
bash-3.00$ /usr/local/rrdtool-1.2.19/bin/rrdtool dump
/usr/local/xymon/data/rrd/server0/iostat-disk.ssd59.rrd | grep last_ds
                <last_ds> UNKN </last_ds>
bash-3.00$

I'm setting up a new test environment with Xymon 4.2.3 to see if I could
get things going.
I'm creating a new iostat script from scratch and trying to get the data
to the trends page.

Well see who wins the race.

Funny you mention that, I just completed a script that does disk iostat,
and graphs all the columns from an iostat -X
(Solaris centric, but I am sure you could mod it for any other OS)

The graphs show up in trends.
For us it made no sense to create an alert based on iostat, but rather to
record it for and use it as a forensic tool if/when things went bad.

It has been running in test overnight, and if all looks good, I will post
it later today.

Hi all,

  I want to create graphs for i/o per seconds on all disks on host
bob.somewhere.com . I am trying to do like the disk check, but I can't
hobbit to create multiple rrd files.

so my check ends up running the following


/usr/lib/hobbit/client/bin/bb 1.1.1.1 "status
bob,somewhere,com.iostat_tps,sda green Wed Sep  8 15:01:49 CDT 2010

      iostat_tps : 23.40
"

/usr/lib/hobbit/client/bin/bb 1.1.1.1 "status
bob,somewhere,com.iostat_tps,sdb green Wed Sep  8 15:01:49 CDT 2010

      iostat_tps : 12.00
"


in hobbitserver.cfg :

I appended "iostat_tps=ncv"  to TEST2RRD
I added NVC_iostat_tps="iostat_tps:GAUGE"

----

I restarted the rrd processes

----

I am not seeing

iostat_tps,sda.rrd
iostat_tps,sdb.rrd

under /opt/hobbit/data/rrd/bob.somewhere.com/

----

my hope is to able to do a graph using something like

[iostat_tps]

      FNPATTERN iostat_tps(.*).rrd


Any ideas ?


hobbit 4.2.0
RHEL 3


Thank !
