I’m trying to find some good open source network monitoring software.

Continuation here https://michaelellerbeck.com/2008/08/04/network-monitoring-zenoss-spiceworks-nagios-hyperic/

First I downloaded the vm version of Zenoss, it fired up pretty easily and I was in to the web interface. I was looking around for some way to do an autodiscovery of the network but couldn’t finid it quickly so I guess I will have to read the manual ūüôā

First strangeness I encountered, following the manual I try to change the password for ‘Zope’ by entering zenpass. But it doesn’t work. I don’t like that. The next thing I notice is an error, something about a problem pinging localhost?? thats strange.

Ok, the interface is pretty confusing. This is what it says

From the left navigation menu select networks. The Networks Overview page appears.
2.  Click the checkbox next to the network you want to add all of the devices from. You can also use Subnetworks table menu to add a new network to the list.
3.  Once you have selected the network, open the Subnetworks table menu and select Discover Devices.
4.  The Discover Device page will appear showing you the status of all the device collections going on.

So what the heck is the table menu you might ask?? Well it looks exactly like a sort column arrow.

Would you guess to select that arrow?

Hmm ok, so It looked like it started doing something… although now I’m getting a bunch of errors?

I deleted and re added the network, and now it was able to find a few machines… but the console keeps on saying Neighbour table overflow???

Well, all and all, it looks cool but still has a few issues to work out.



  1. I’m guessing the localhost ping problem is probably because you have and 192.168.1.X (or whatever your local network is) defining the same machine in your /etc/hosts.

    The “zenpass” bug has been noted in an existing bug.

    The ping error is based on an unexpected response of a redirect when we were expecting a reply of some sort. If you could provide any details about the machine or setup that caused it, I’ll open a trac ticket.

    We’re in beta for our 2.2 release if you want a fresher release. I appreciate any feedback you have and if you need any assistance please let me know.
