Today you sent me mail regarding [rrd-users] Re: Help using rrdtool update:

*> Two things:

*> 2) Try debugging
*> 
*> How?
*> 
*> 1) Alter your scipt:
*> #!/bin/ksh
*> in="`snmpget -v1 $1 $2 2.2.1.10.1 | awk '{print $3}'`"
*> out="`snmpget -v1 $1 $2 2.2.1.16.1 | awk '{print $3}'`"
*> /apps/RRD/bin/rrdtool update /apps/RRD/mycsx.rrd N:$in:$out
*> 
*> 2) Change "/apps/RRD/bin/rrdtool" into "echo" and inspect its output.
*> 
*> You may have spaces in the output of snmpget. Because of the quotes
*> these won't get removed. This may upset rrdtool.

if you manage to get a core with a simple commandline I would be most
interesting in knowing what commandline this is ...

cheers
