memory test problem

[dOCtoR MADneSs <doctor (at) makelofine.org>]

Hi,

I'm running xymon client 4.2.2 on a NAS (arm based) running linux, i 
compiled successfully xymon for running on it. almost all is perfectly 
running.
I can't get memory tests, when I do the following :
mkdir /usr/local/xymon/client/test
BBTMP=/usr/local/xymon/client/test
MACHINEDOTS=test
Then :
[xymon (at) nassounet test]$nohup sh -c "vmstat 300 2 
1>$BBTMP/hobbit_vmstat.$MACHINEDOTS.$$ 2>&1; mv 
$BBTMP/hobbit_vmstat.$MACHINEDOTS.$$ $BBTMP/hobbit_vmstat.$MACHINEDOTS" 
</dev/null >/dev/null 2>&1 &
sleep 5
if test -f $BBTMP/hobbit_vmstat.$MACHINEDOTS; then echo "[vmstat]"; cat 
$BBTMP/hobbit_vmstat.$MACHINEDOTS; rm -f 
$BBTMP/hobbit_vmstat.$MACHINEDOTS; fi

A file is created, and contains the following :
[xymon (at) nassounet client]$ cat test/hobbit_vmstat.test.8579
procs -----------memory---------- ---swap-- -----io---- -system-- 
----cpu----
 r  b   swpd   free   buff  cache   si   so    bi    bo   in   cs us sy 
id wa
 1  0  10880   3052  11592 130480    0    0     2     0    4    4  5  4 
92  0

So everythin seems running fine, but I can't get memory test results on 
my xymon server.
Could someone help me with it ?

Regards,
Damien
