Hello,
I have downloaded NAV to test in my company. I have installed the software and configured around 30 production switches and routers to see how the tool works.
Everything is going well except for one point. When I open the Netmap module, I can see a graphic representation of all devices on the page, however the lines connecting the devices are all green even if the device is reporting down. (If I click on it there is a red icon on the top right side of the window).
My question is, what is the criteria to change the graphic representation to red ? E.g. If the device is not reporting SNMP but it is replying ping, should the status be green ?
Thanks in advance,
Fernando.

I hope you find it useful :-)

The color of the lines do not indicate device status, they indicate the general traffic level on the link. As the colored legend bar below the map indicates, green is generally interpreted as less than 30-40% of the link's capacity is being used (while a grey line indicates that NAV is missing recent traffic data from the link).
Thank you for your reply.

Yes. I am still studying it but it looks an excellent tool.

I added a device to the database but it did not appear on the Netmap. Is there any rule for a device to show on Netmap graphic ? When I loaded a group of devices using the bulk import option I don´t have this kind of problem.
I have 6 switches not reporting to NAV. I would like to see on Netmap a different icon indicating they are offline but Netmap does not change their icons to red or any other status. They all look "normal", Is it correct ?
Thank you.

Nodes that have no known links are not shown by default, since Netmap is a link-centric view (after all, how can you have a topological network _map_ if you don't know where things are?).
You can toggle "Display isolated nodes" in the view options if you want to see linkless nodes.

The Netmap is not a box status indicator, true. What you are asking for is described in https://github.com/UNINETT/nav/issues/1141 - but we recently closed that issue as a "wontfix" issue, since no-one has voiced an opinion on the matter. You're welcome to add your comments to the issue :-)
