For general purpose monitoring (eg tracking temperatures etc) then you may find
Cacti more useful - or RRD and some customer scripting. For general monitoring
and alerting I use Nagios.
With some external scripting, you can use stats collected by some of the Nagios
plugins and stuff it into RRD files which Cacti can graph.

It depends how the KVM guests are connected to the network. Is the host
bridging or NATing? If the MAC addresses of the guests appear on the
network (bridging) then they'll appear alongside the host on the
upstream switchport. If NAT is involved, then you need to treat the KVM
host as a device in its own right, and run an SNMP agent so information
can be discovered. See also:

https://metacpan.org/pod/release/OLIVER/App-Netdisco-2.031012/lib/App/Netdisco/SSHCollector/Platform/Linux.pm
(You'll need to upgrade to 2.031012 to use these features, which are
only just released.)
could this be done using netdisco or should i look for a more general
purpose application ?
I echo what Simon said - you'll be better off with another application
for the graphing type workload. One that I favour is Observium, which is
free (but not open source) and does a good job of
autodiscovery/autoconfiguration.

Hi,

I am trying to get the arp table from a linux net-snmpd but it fails:

This is the important message - the device isn't reporting OSI Layer 3
capability (in other words, routing), so Netdisco will not attempt to
retrieve the ARP table.
There's no way to override this behaviour, but what you can do instead
is use a brand new feature just released in version 2.031012 (so you
will need to upgrade, and set up a cron job for the sshcollector helper
app).
https://metacpan.org/pod/distribution/App-Netdisco/bin/netdisco-sshcollector
https://metacpan.org/pod/release/OLIVER/App-Netdisco-2.031012/lib/App/Netdisco/SSHCollector/Platform/Linux.pm
Thanks to Mike for submitting the patch for this (perhaps reading your
email and spotting the solution ;).
Normally I would get the arp table from the router/firewall but the
default
gateway is a Palo Alto Networks device which does not support getting
the
Arp table via SNMP.
Any Ideas how to get the IP<--> Mac Mapping into the netdisco
Database?
Ah, in which case you can use the sshcollector I mentioned just above -
we already have PaloAlto support:

As a clarification, look for OMD. It packages Nagios and Pnp4Nagios
together. Which allows you to chart and alert all-in-one. And adds
check_mk to make Nagios a better Nagios.

Sorry to butt in but I have several Dell 5524s so here's some output

Many thanks, Jon!
So I've made a blind stab at fan and PSU support, and you can try by
copying the following file over the existing one:
https://sourceforge.net/p/snmp-info/code/ci/master/tree/Info/Layer3/Dell.pm?format=raw
copy to:
~netdisco/perl5/lib/perl5/SNMP/Info/Layer3/Dell.pm
And then run a discover on the device. As it's untested, it may not
work ;) so let me know how you get on.

Hi,
I am using the latest Netdisco2 from meta::cpan as of yesterday.
Most of these VM are dual homed, natted to the libvirt host for outgoing
connections to the internet and bridged for access from inside corporate lan.
I have also took a look at observium which i am using since a while as i was
unable to get netdisco 0.9x and 1.x to inventory ports and draw my corporate
network map which comprises a lot of alcatel-lucent devices.

Hi,
I am also looking at opennms and maybe at zenoss in a later time for overall
monitoring.

Hello,
I am occuring these problems with macsuck on my Backbone Routers (which are
both Cisco Catalyst 6500):
1)Macsuck takes very long (>3 hours) on these devices
2)While macsuck runs, the CPU is at 100% on the device, which causes other snmp
requests (e.g. from other monitoring services like cacti/icinga/etc.) to
timeout.
Is there an easy fix for this behaviour or should I just blacklist these
devices for macsuck (with the macsuck_no option)?
I am using Netdisco 2.029014
best regards,
Dirk
