 Each NAV report is in essence an SQL query to the database. It shown its data in a number of columns. The
 data is in many cases also hyperlinks to other reports or other tools in NAV. The whole report system
 is highly configurable, the basis for the system is the configuration file report.conf. Details on
-the configuration is provides below.

-===== IP Device Center =====
-The IP device center is a dashboard for a given device showing relevant information. It presents

+For large networks the task of maintaining the total IP address scope may be a challenge in itself. It is useful to have an overview of all the subnets in operation, and what is more, how full they are, i.e. how many machines they contain. NAV introduces a tabular view that gives an excellent overview on a single page:

+A prerequisite for this tool to work is that you have seeded your database with one or more scope prefixes. The scope prefixes defines your total address room. You may have both IPv4 and IPv4 scopes. Each scope can be visualized as shown in the example.
-{{screenshot:prefixmatrix.png?800|The prefix matrix }}
+You may also use the reserved prefix option in Seed Database. A reserved prefix is a prefix that is allocated for a purpose, but is not yet in production. For more info on registering scope and reserved prefixes [[seedessentials#prefix|see here]].
+A brief explanation of the functionality in the prefix matrix:
+  * Layout
+    * For IPv4 each row is a /24 scope and the columns counts from 0-255
+    * For IPv6... (to be completed)
+  * A coloured area means that this prefix is in use or allocated
+    * reserved prefixes are brown
+    * in cases where there are many small subnets (meaning too small to display in a good manner), the row is blue
+    * prefixes in use follow a colour scheme based on their utilization rate:
+      * a very heavily used prefix will be red
+      * a lightly used prefix will have a light colour
+  * The displayed percentage is the actual percentage of the IP addresses in the prefix that are in use. If you click on this link you will be directed to the machine tracker that can display the actual IP addresses (and mac addresses) that are in use.
+  * If you click on the row titles on the left you will be directed to a report displaying all prefixes in that area
+  * If you click on an actual allocated prefix you will e directed to a report displaying details regarding this prefixes
+  * If you uncheck the "Show unused address rows" you will get a collapsed view removing rows where there are no allocations.
 ===== Service matrix =====
 This tool is quite simple and only useful if you use the NAV service monitor to an extent. It displays
 all servers and services in a matrix showing operational status.
 ====== Configuration ======
-As mentioned the report system is higly configurable, you can alter the configuration file report.conf.
+As mentioned the report system is highly configurable, you can alter the configuration file "report.local.conf", either adding new reports or overloading existing reports that exists in "report.conf".
-In NAV 3.4 we will strengthen the means of editing reports by adding support for local reports,
-see [[devel:tasklist#smj3improve_the_report_tool|Task SMJ3]].
+==== Report configuration ====
+The NAV reports are made based on the ''report.conf'' configuration file. You can expand this file
+with new reports as you like in ''report.local.conf''. Each report is in essence an SQL-query to the database (with some
+limitations). It is easy to make hyper links from data in the report to other reports or elsewhere.
+An example report is given, this is the router port report:
+<code>
+gwport {
+$description = "Extended information about router ports.";
+$sql= "
+ SELECT netbox.sysname, gwport.ifindex, gwport.interface, module.module,
+        gwport.link, gwport.speed, prefixcount, metric, netbox.netboxid,
+        gwportid, gwport.portname, n2.sysname AS otherbox, swport.interface AS remoteif
+ FROM netbox
+ JOIN module ON (netbox.netboxid=module.netboxid)
+ JOIN gwport ON (module.moduleid=gwport.moduleid)
+ LEFT JOIN (SELECT gwportid, COUNT(gwportid) AS prefixcount
+                 FROM gwportprefix
+                 GROUP BY gwportid) tempaggr1 USING (gwportid)
+ LEFT JOIN netbox AS n2 ON (gwport.to_netboxid=n2.netboxid)
+ LEFT JOIN swport ON (gwport.to_swportid=swport.swportid)
+";
+$title = "Router ports";
+$hide = "netboxid,gwportid";
+$name_sysname="Router";
+$name_interface="Interface";
+$name_gwip="IP address";
+$name_speed="Mbps";
+$name_portname="Description";
+$name_prefixcount="#prefix";
+$name_otherbox="Connected to";
+$name_remoteif="Remote if";
+$order_by="sysname,ifindex";
+$url_sysname="netbox?sysname=$sysname";
+$url_module="modules?sysname=$sysname&module=$module";
+$url_prefixcount="gwip?sysname=$sysname&ifindex=$ifindex";
+$url_otherbox="netbox?sysname=$otherbox";
+$url_remoteif="swport?b1.sysname=$otherbox&s1.interface=$remoteif";
+$explain_gwp="Router Ports";
+$sum="gwport";
+}
+</code>
+The syntax of the report configuration is:
+Each report is enclosed within brackets:
+<code>
+      	r1{
+            ...
+          }
+</code>
+This report is seen as ''https://your_nav/report/r1''
