[rrd-users] Re: perhaps a dummy question, but i got hang up ...

[Chris Marlow]

Do you run this as a perl script?  If so, sometimes perl will interpret the
":" between the numbers incorrectly.

As a fix, assign your command to a variable first....
     $Command = '/usr/local/rrdtool update cisco.rrd N:' . $in . ':' .
$out;
     @ReturnString = `$Command`;

(Note the single quotes in the first line, and backticks in the second)

Also, check to make sure that $in and $out don't have newlines attached to
the end of them from the
return string.  Use:
     chomp($in);
     chomp($out);

Let me know if this helps.

Subject:  [rrd-users] perhaps a dummy question, but i got hang up ...




well,

i read the tutorial to get familiar with rrd (i used to work with mrtg
before).
all right till now, but as i tryed to do the "real world example" i ran
into chaos...

ok, i built the rrd database, and i am familiar with SNMP, so it was no
problem to find the right oids for my router.

snmpget ...... => $in
snmpget ...... => $out

but when i try to update my newly created rrd database i get this error.

rrdtool update cisco.rrd N:$in:$out

ERROR: expected 2 data source readings (got 1) from N: ...

i`am shure there is someone who can help me...

btw.: i am searching for some examples or tutorials which describe how
to manage or to analyse a network with active devices (router, switch...)
using rrd and/or mrtg (rrd prefered) perhaps with the help of some perl
scripts

Thanx beforehand
Frank
