Title: Is there a guide or manual?
Post by: lschafroth on January 04, 2010, 05:40:19 PM
I have the nedio45 iso installed and finally figured out how to get past the infinite install loop where it keeps asking for the packages and cdrom to install from. I finally said done and it asked if I was sure and I said yes even though it warned me about bsd.pm or something and it finally worked.

I edited nedi.conf and put in our snmp info and login on our cisco switches. We do not allow telnet, jut ssh to our switches.  I ran ./nedi.pl and it found our core switch and now it's just sitting there.  Is it doing anything?

Where is the manual showing every option in the gui?  I'm a newbie and need help.

I need to use nedi to document our cisco network and monitor/troubleshoot bandwidth and etc through the interfaces and between buildings.

I found the verbose command and I cancelled the first run of nedi.pl and ran it with the -p -v options and now I can see what it is doing.

Do I still need to add it to the cron to schedule it?  I want to be able to see bandwidth used. I know in cacti this is done every 5 minutes. Do I schedule that?

I have 46 devices.  Most of which are cisco wireless access points.
The cron examples still show the -c paramter which is no longer valid.

How would I setup a cronjob to monitor my bandwidth as often as possible without interrupting or degrading any performance on the switches?

I have a few cisco 3750 stacks of about 4 switches each that are all full, the rest or jut normal 48 port 3750's or 3500's.

I'm a unix newbie so help me design a cron/schedule for my setup.

Thanks!!

PS I know I've posted all my WANTS so far, I do LOVE the product so far so keep up the awesome work.

No worries, I'd also be very eager to get that thing up and running  ;)

5 Minute graphs with around 50 devices are on a tight schedule! You can run concurrent discoveries, but I wouldn't recommend it to get 5 min graphs. OXO is working on an optimized version, which allows for such graphs...

A few pointers:

I did all the editing from the gui.  I changed the nedi.conf and check the lastrun.

So I should set the cron to run maybe every 1/2 hour but set the rrdtool to run every 5 minutes?  Or 15 minutes?

When it first ran I saw all the graphs and it was exactly what I wanted.  Then I fixed the permissions and now the graphs are gone.  The first ./nedi.pl was run from root.  Thats when things looked ok.  Then I ran it from the gui and thats when I saw the permission denied.

Do I need to wipe the system and start over and only use the gui to make changes?

I've messed something up.  Graphs are the main reason I wanted this and now they dont show.

I tried the ./nedi.pl -i option but it is asking for the mysql root username and password. Since this is a iso image, what would those credentials be?

I reinstalled from scratch and ran the initial scan from the gui and now everything works!!

Now I just need clarification:

I would like to update the graphs as often as possible.  The full scan takes about 4 minutes so that is pushing the limit for a 5 minute window.

In the cronjob, how often should I run the ./nedi.pl -poB and the normal ./nedi.pl -po?

What should I have the rrdtool set to in nedi.conf?

Thanks for all your help so far!!

I noticed the only thing I have for graphs is memory, cpu and etc.  How do I show the bandwidth being used by the backbone ports and etc?

Lannie

DISREGARD: Found the graphs!  Is there a way to make a custom webpage that I can have a drawing of my backbones and the bandwidth graphs in them?

How does 60 sec for 150 devices for graphs and 6 min for a "full" nedi run sound?
snmp bridgefwd and no backup of configs
- with bugs of course :)
