Announcement: NAV 4.2.0 released

The feature release of the new NAV 4.2 series is now available.

The source code is available for download at Launchpad [1]. A new
package for Debian Wheezy has been published in our APT repository [2],
as usual.

Changes
=======

The following new features and changes have been introduced:

  * LP#1063703 (The status page is becoming cluttered and should be redesigned)
  * LP#1374384 (Adding new devices to a room on maintenance does not put those
                devices on maintenance)
  * LP#1383624 (Machine Tracker should search uplink data as well)
  * LP#1383625 (Machine Tracker MAC search should also search physical port
                addresses)
  * LP#1384262 (Add unrecognized neighbor search to navbar)
  * LP#1388078 (Add IGMP Multicast group usage statistics to NAV)
  * LP#1389226 (Arbitrary attributes on netbox and location)
  * LP#1390073 (Add support for AKCP sensorProbe8)

  * LP#1388835 (Maintenance Engine needs a rewrite)
  * Netmap has been redesigned to fit better in the NAV 4 design.

Please refer to the release notes [3] for further information on
upgrading.

Happy NAVing everyone!

Additional SNMP Polling through NAV

I am really new to NAV, but I've liked it so far in my lab testing.  I do have
some routers whose CPU utilization is not showing up, and I would like to poll
some non-standard OIDs (like IP SLA metrics) even if NAV won't display them.
I could use graphite to do that for me separately, but utilize the engine that
NAV provides.  Could someone point me to where I might need to go to do that?

Is there an OID somewhere that could be added or updated to support newer
router CPU metrics, so that my Cisco ISR-G2 routers will have that displayed?

How can I customize the polling of some devices (mostly Cisco routers) to get
additional metrics?  I have not found where I can modify or add scripts to do
this and need some general pointers on where to look on the internet as well
as on the system.  Since this is just a lab environment, I have all the NAV
components on one server.

Thanks,
Joel

Integration with GIS

Before I start doing such, I'm wondering if anyone has done any 
integration between NAV and a PostGIS based GIS system (mostly using 
QGIS for "frontend"), as I would rather add to existing work rather than 
repeating it...I thinking of just creating views in postgres referencing 
NAV data for the GIS to use to retrieve device inventory, status, and 
statistics in spatial queries. If it becomes successful and useful, I 
will do a writeup.

Setting up NAV from scratch/non-OVA (Graphite-issues)

Hi,

Decided to install NAV from 'scratch' (i.e. not use the OVA-package). Got NAV running fine, but had some
hiccups getting Graphite working as it should. Found no documentation on this what-so-ever (neither on
the NAV-pages, or the Graphite-pages), so had to try-and-fail some. Thought I'd share.

 - Debian Wheezy (not OVA)
 - NAV via apt (from https://nav.uninett.no/debian)
      root <at> tardis:~# dpkg -s nav|grep Vers
      Version: 4.0.1-3

1) Fixed /etc/nav/graphite.conf;
	base=http://localhost:8888/

2) Copied content of '/usr/share/graphite-web/apache2-graphite.conf' into own VHost;

	( + add NameVirtualHost + Listen in /etc/apache2/ports.conf)

3) Set 'CARBON_CACHE_ENABLED=true' in '/etc/default/graphite-carbon'

6) Started NAV + apache

Is there a way to change the default 10 rows in the lists?

It should be useful if I can change the default 10 rows in the

"Show xx entries"

in the lists.

I searched through the configuration file and in the .js but I can't change
this.

I wish to put 50 rows or at least "all".

Thank you

You can't. All information in the interface table consists of
collected/detected information. Any changes made outside of NAV will
only be temporary.

If you would post details of your actual topology, where NAV is
mistaken, and add the details collected as described in [1], we may be
able to make a more qualified comment as to what may be happening. Feel
free to replace device names and text you would rather not divulge, as
long as you do it consistently.

Yes, this likely means the Carbon backend is not running, so NAV cannot
send its metrics to it. Please start the carbon-cache backend.

Re: Shutdown a port

Hi!

It is not possible to change the administrative status of the interface from
PortAdmin. The reason for this is that it simply has not been requested from the
NAV users.

The tool used for setting the interface administrative status is Arnold. The use
case for Arnold is that you have a mac- or ip-address that you want to shut out
from your network, so you search for that in Arnold and set the administrative
status of the resulting interface.

However, if you wish to manually set administrative statuses from PortAdmin,
that is something we can implement. Please register a bug for this on
https://bugs.launchpad.net/nav/+filebug and we will handle it.

Re: Problem with uplink detecion

NAV will traverse the path of each VLAN individually, starting at the
determined root router port for that VLAN. NAV does not get root
information from STP, but has detected which subnet prefix(es) are
routed on that VLAN, and uses this to detect the root router port. 

On the device connected to that router port (or on the same device, in
the case of an L3 switch), NAV will descend further on all trunks with
the current VLAN allowed, and non-trunks having this as their native
VLAN.

STP information is only used to find STP blocked ports. STP blocked
ports will not be traversed by the detector, only registered as blocked
on the VLAN that is being detected.

You mean a mismatch in the list of allowed vlans on each side of a
trunk? That would be logged as an error.

NAV mac-search with Nexus and FabricPath

Hi,

we have FP activated in our datacenter and use Cisco Nexus (5,6,7)k. I'm not sure what caused the problem but NAV can't find MAC-addresses on these devices and even on catalysts behind them anymore. I don't know what algorithm is used to figure out where a MAC-address is attached but maybe someone who knows can clarify what is needed for that to work?

Thanks in advance,
Mischa
