Introduction

This module was intended for documentation purposes, even though it features interactive handling now. Refreshing every 10 minutes it can also be used to observe traffic, errors, broadcasts, discards, cpu usage or temperature of devices.

It requires the php-gd extension and “proper” SNMP location formatting on your devices as described on the NeDi homepage (you can still draw flat maps, if that's not the case).

Maps are written on a per user basis to html/log (make sure it's writable by the webserver). Upon accessing this module an existing map will be displayed (no interactive features), without any adjustment of the input form.

Graphs are only drawn in PNG and only for the 1st time the map is generated, because they'll be deleted afterwards. This may be a problem, if you wish to save the picture (screenshot always works, though). Alternatively SVG or even interactive json maps (devices in flat map type only) can be created. The node you click on moves to the center and the whole map adjusts itself around it. The source of the map can be used in other applications as well.

Usage

Details

The map is drawn based on your snmp location strings and those parameters: A geo map will try to find the best suited background image automatically. E.g. the regional one, if you're only drawing one region and you've copied a map-\.png into html/log.

Assuming you've edited this region with Loced before, it'll now use the city coordinates, you've entered to locate the city icons with the region. If you draw at building level, they'll simply be arranged around the city coordinates using circle mode and above parameters.
