Hi Joseph,

While digging around last night, I found that netdisco2 should be
using netmap with 3d library? I see where its calling for side bars
in the css file.
I'm a bit confused by what you're saying here. Yes, Netdisco 2 uses the
"d3" javascript library but it's included with the Netdisco installation
so there is nothing extra to install. Are you saying that it's not
loading in your web browser?
Perhaps you can try the public demo site. You should see a really
simple netmap of two or three devices:
http://netdisco2-demo.herokuapp.com/device?tab=netmap&q=router-16.example.com&depth=8&vlan=
If nothing displays, can you let us know what web browser you're using?
Is JavaScript enabled?
regards,
oliver.
What needs to be installed to make this work and what settings do I
need to make in any conf files?
If NetDisco2 doesn't support a Graphical Network Map yet, thats cool,
I will dump this setup and do a manual install of the latest 1.3.3
version which runs with GraphViz.
Please let me know.
Joe

Hi Everyone,
I am installing Netdisco2 using the instructions
at https://metacpan.org/pod/App::Netdisco [1] and I am not able to
figure out how to setup and incorporate GraphViz. In Netdisco1 it
was there.
Also, can someone point me to a list of Plugins that are available
for Netdisco2?
Thanks
Joe

Hi,
I have inherited a NetDisco 1.1 installation and I want to upgrade it to
either 1.3.3 or version 2.0. I would appreciate your advice whether I
should go for 1.3.3 or 2.0 and also please provide me with the instructions
to upgrade from 1.1 to 1.3.3/2.0.
Regards,
Ahmer Zakir

We recommend you upgrade to Netdisco 2. The process is documented here:
https://metacpan.org/pod/App::Netdisco
Some notes for you:
* backup your database before starting the work
* Netdisco 2 and 1 can co-exist happily on a web server, except...
* the Netdisco 2 backend daemon and its "housekeeping" config replace
the Netdisco 1 cron jobs
I hope this helps,
regards,
oliver.

HI All
I have a Netdisco 2 deployment and I have a network of Huawei switches that it
is querying. Currently the vendor is discovered as unknown and I would like to
add the different Huawei mibs into the system. From the Netdisco 2
documentation it does not seem very clear on the process for this.
Can anyone give me some guidance for adding additional device mibs to the
system on Netdisco2?

Take a look in the ~/netdisco-mibs/huawei/ directory.
There's probably an updated version of one of those files available to
identify the new model(s). Let us know what it is and where we can get a
copy, and we'll update netdisco-mibs for you.

Hello all,
I installed netdisco 2 on Ubuntu 14.04 server 64 yesterday using the
instructions at
http://www.wiki.cl.cam.ac.uk/rowiki/SysInfo/NetdiscoInstallationNotes. The
initial db deploy works fine as the netdisco user but when I try to start the
web component it says it succeeds but an immediate status confirms that it is
not up. It comes up and answers requests on port 5000 if I start it as the
root user. I've done a find for user root in NETDISCO_HOME while it is up and
the only file owned by root is the pid file, everything else is properly owned
by netdisco. Are there any files that are created outside NETDISCO_HOME that
it might be choking on?
Thanks,
Frank

Hi Frank,
Many thanks for trying out Netdisco 2.
I suggest you use the official installation docs at this page:
https://metacpan.org/pod/App::Netdisco
The notes from the web page are useful but unfortunately don't take
into account changes to the application (such as that port 80 can be
used, and so on).
If you have trouble after following the above link, please let us know.
regards,
oliver.

Pulling the vlan inventory report in Netdisco2 is really slow in my
installation (postgresql 9.1, up to date nd2).
The code in VlanInventory.pm produces this query:
SELECT vlan.vlan, vlan.description, COUNT( DISTINCT( ports.ip ) ),
COUNT( ports.vlan )
FROM device_vlan me
LEFT JOIN device_port_vlan ports
ON ( ports.ip = me.ip AND ports.vlan = me.vlan )
LEFT JOIN device_vlan vlan
ON ( vlan.ip = ports.ip AND vlan.vlan = ports.vlan )
WHERE ( vlan.description != 'NULL' )
GROUP BY vlan.vlan, vlan.description
It's called once, wrapped in a COUNT(), by
return unless $set->count;
then once again when feeding to the output template.
In my installation, each query run takes around 35s, for an average total
pageload of 70s.
Rewriting the SQL as
SELECT vlan.vlan, vlan.description, COUNT( DISTINCT( ports.ip ) ),
COUNT( ports.vlan )
FROM device_vlan vlan, device_port_vlan ports
WHERE ( ports.ip = vlan.ip AND ports.vlan = vlan.vlan AND
vlan.description != 'NULL' )
GROUP BY vlan.vlan, vlan.description;
drops the pageload time to around 1.5s and seems to produce the same
output.
I'm not familiar with DBIC. Is anybody already working on adjusting the
code to produce more performant SQL on the backend?
