Discovery / Re: Switch discovery load a lot the CPU(switch)

The problem is in order to read forwarding tables on Cisco switches NeDi needs to do something calle vlan community indexing. Effectively NeDi walks the forwarding mib with each vlan appended to the community (e.g. public@1, public@2 and so forth) in order to collect all nodes. You typically see a lot of warnings related to empty forwarding tables in this case as well.

Because of this I implemented the CLI alternative for getting forwarding tables. NeDi then uses telnet or SSH to get the info via CLI. As I just got a donation in regards to this topic I'm going to write some more documentation here:http://www.nedi.ch/doku.php?id=discovery:discovery

BTW I've been thinking about custom graphing as well (for years actually) and while hacking some .defs to provide associations on Wlan APs etc. is quite dirty, I think I have a solution though.

Coming from Cisco I've provided a dedicated value for IO mem. My question to all of you is, how important is this to you? Don't worry I'm not going to take it away, but make it customizable to graph more valuable information, if applicable...

Ah I see and even remember working with your data :)
It may be easier to integrate a ccc column to the list instead...will look at it, when time permits.

How many vlans do you have configured on that thing?

Can you use the more recent Device-Modules instead?

Rufer's statement is my credo, as there's enough complex stuff out there  ;)

Anyhow, not all rrds are counters. Just look at the system rrds...but maybe I didn't quite get what you ment. But why focus on graphs? This is NeDi not Cacti  ;) I had a go at "expanding" Device-Status for print supplies (see attached). It would be easy to generate a report of top empty toners etc. While I want to keep NeDi's main focus on network devices, this would be an interesting benefit for more general IT admins (pure networkers don't have to discover them, hence shouldn't be bothered). Printers then are treated as any other SNMP-enabled network infrastructure device.

Thanks, I had a .def for the 53 but it was pretty bad. I've merged  your suggestions with it. BTW I've decided to use a more appropriate type scheme like HP5304xl as the J# shows in the description anyway. Icon is c3gp as it's a small, chassis based layer3 switch...

It wold definitely not be NeDi's focus to monitor printers, but on the other hand....amazing potential! As I work for (kind of) a printer company now it even makes sense  ::)

You'll only need to find the proper OIDs, add Hewlett to ouidev and make sure descfilter plays along as well and off you go. You can even monitor the printers then, have them send syslog messages to NeDi (if they can do that) or show printers on maps. The more I think about it the more I like the idea, as this would broaden NeDi's clientbase to printadmins as well! Hmm, a NeDi-PRT edition falls into mind...

My 4000N doesn't seem to be that good with SNMP but at least I could specify a syslog host:

Code: [Select]
  ===JetDirect Telnet Configuration===
Firmware Rev. : G.07.17
MAC Address : 00:60:b0:f3:f7:bb

IP Address :
Subnet Mask :
Default Gateway :
Syslog Server :
Idle Timeout : 90 Seconds
Set Cmnty Name : Not Specified
Host Name : HERMES

I can't reproduce this behaviour. It's also been tested with a 7912 before, therefore I'm a bit at a loss here  ??? However it does look like it's always matching from the beginning.

To further narrow down the problem, you can add a print "EXT::$1::"; statement before line 40 to check whether it uses the right match operation?

If ok, change \W+ to \W{0,2} to see whether there's a problem with the line endings.

Please let me know of the outcome. BTW is it running on a win host?

I realized only recently, that IE messes up my carefully crafted div alignments  :-\

Anyhow, for all having problems with CLI stuff, you've got 2 options:

1) Be patient. The upcoming release is the last one I put any efforts into the current CLI routines. Net::Appliance seems to be much better and some community members made great contributions already. It's just a matter of merging their code, with the next release(s).

2) If #1 doesn't apply to you, search the forum. I posted quite some hints about turning on logging and narrowing down the issues. However I understand it's a very annoying issue and it lacks proper documentation. I'll put up a troubleshooting guide on the wiki, f I find the time...

Thanks, will be included in the next release...

Monitoring Setup has nothing to do with graphs, but your rrdpath still points to Perl! That doesn't seem right to me...

rrdpath should point to the rrd directory in your NeDi directory (like /var/nedi/rrd)!

It's not so bad for nedi itself (still only 2Mb), plus I don't want to loose the hits as Adsense pays some bills (to keep NeDi going). I definitely consider torrent for the ISO though...

Good stuff! I put it in the contrib folder with a commented entry in nedi.conf...we'll need to check if it will work with the next release...
