Vmstat data for IRIX systems 🔗 link

Hobbit currently does not handle vmstat data coming from IRIX systems.

Indeed, on my former BB install, I hacked the bf-vmstat.sh script a
little and made it use "sar" to report data to be processed like
vmstat data from other hosts.

The bf-vmstat.sh script I use is:

#!/bin/sh

# $Id: vmstat-bf.sh,v 1.1 2000/11/30 20:29:44 scott Exp $
# vmstat-bf.sh

# variable definitions
MET=vmstat
VMSTAT=/usr/bin/sar
OUT=$BBHOME/tmp/$MET.$$

#################
# COLLECT
#################

# vmstat
echo "$BBOSTYPE" > $OUT
# get the data
$VMSTAT 300 2 | $TAIL -1 >> $OUT

##################
# REPORT
##################

if [ $LARRDCOMM = DATA ]
then
        $BB $BBDISP "data ${MACHINE}.$MET
`$CAT $OUT`"

else
        $BB $BBDISP "status ${MACHINE}.$MET green `date`  <$MET>
`$CAT $OUT`"

fi

rm $OUT


/usr/bin/sar xx 2 output looks like that:

bb at rhea:~/ext/bf-larrd> /usr/bin/sar 10 2

IRIX64 rhea 6.5 10070055 IP27    05/20/05

11:44:20    52     3     0     0    45     0     0     0     0     0     0

The vmstat-larrd.pl entry I use is:

          irix   => {  cpu_usr  => 1,
                       cpu_sys  => 2,
                       cpu_int  => 3,
                       cpu_w  => 4,
                       cpu_idl  => 5,
                     },


How could I hack hobbit so that it may be able to deal with this ?

PS : I have similar hacks for the Super-UX OS run by NEC
supercomputers (I run BB clients on both of these)

Something like the attached patch should do it (I think it applies to
4.03rc2). It assumes your IRIX hosts have a BBOSTYPE that begins with 
"irix".

I have changed the RRD definition from yours - the "cpu_w" dataset is
normally called "cpu_wait", and I've added a "cpu_csw" dataset because
that will allow you to use the vmstat3 graph definition un-modified.
That means your current vmstat RRD files from IRIX will not be usable 
with Hobbit, as is the case with most of the vmstat RRD's.

Yes, that's it. Indeed I never bothered trying to find whether vmstat
could be used on IRIX..:-)

I'll probably wait for official releases...if you plan to include this
(not sure as this may be considered somewhat specific to my setup).

In fact, I have decided to stay with official Hobbit releases on the
server, now...and just use the Debian packages you provide (and, yes,
I remember I said I would look at it...:-)).

I've included it in 4.0.3, but with a warning that it may change. If
vmstat does work on IRIX, I'd prefer to use those data since they are
probably a bit more detailed than what you get from sar.

It would also be nice if you could show me what the "netstat -s" output
looks like - then Hobbit would be able to track these data as well for
IRIX.

I know how you feel ...
