Re: [Devmon] T or even P bits speed output in 'home made'-cisco-n7000 switch template

[Peter W. <pet...@gm...>]

Until now I checked and reproduced the error on two similar RHEL6 servers:

-both vm's
-Xymon version *Xymon 4.3.27-4.el6.terabithia
<http://xymon.sourceforge.net/>*

Perl v5.10.1

net-snmp-libs-5.5-57.el6_8.1.x86_64
net-snmp-5.5-57.el6_8.1.x86_64
net-snmp-utils-5.5-57.el6_8.1.x86_64
perl-SNMP_Session-1.12-4.el6.noarch
rrdtool-1.5.5-1.1.el6.x86_64

-devmon: I tried two versions. One old version  $Id: README 96 2008-12-07
20:01:21Z buchanmilne $ and the newest from svn://
svn.code.sf.net/p/devmon/code/trunk but the behaviour is the same for both.
Spikey to Tb of Pb :-(

A script that queries the device showed no problem. So it suspect the
problem to be somewhere near the integration in Xymon and rrdtool, I think.

A snippet from the rrd-file itself (*bold* shows where the spike is shown
within Xymon):

Since the template works for me on the old Xymon-server (SLES, Xymon
version old, etc) I ask this here to know if someone else has experienced
or currently experiences this behaviour?

Although this seems to me a low traffic mailing list, I do know that there
are many others using the great tool devmon for querying remote devices and
have it integrated within Xymon.
