-====== Netmap ======+====== Netmap ​- the network weather map ======
-Netmap ​is the vlanPlot ​(TrafficMapreplacement current under development.+{{tools:​vlanplot.png|}} ​Netmap ​was introduced in NAV 3.5 written in Java and replaced ​the old traffic map ([[trafficmap|vlanplot]]). Netmap got rewritten from scratch using open standards as HTML, JavaScript and SVG (Scalable Vector Graphics in XML markup).
-Netmap ​will offer some more features than vlanPlot.+Netmap ​is based on the [[http://​|D3JS]] library, and uses its [[https://​​mbostock/​d3/​wiki/​Force-Layout|ForceBasedLayout-engine]] for finding the optimal graphical layout for the network topology. Netmap should work in all new common browsers that support SVG (IE9 and newer), Firefox (3.5 (really recommend a newer version, as the firefox javascript engine is having performance issues) and up), Chrome (auto updates, testing with Chromium in Debian Squeeze at least). Opera has some issues that we will look into later 
-The preliminary specs for the app are in the tasklist, listed as SS1 under Kristian Klette'​s tasks.+===== Features =====
-New features include: 
-  * Dynamic layout with zoom, pan, and search/​track capabilities 
-  * More stats about devices 
-  * See the whole network visualized, not only the router stack (you can filter out items though) 
-TODOAdd more+Netmap has these features (in no particular order):
-----+   * Dynamic generation of network-topology based upon prefixes for gwports, and the to_swportid field for swports (discovered by [[backendprocesses#​ipdevpoll|ipdevpoll inventory job]] and [[backendprocesses#​topology|topology]] (cronjob running every hour)). 
 +   * Fetching of rrd-load data for links between netboxes (links are colored by relative usage for it's interface speed) 
 +   * Links capacity between netboxes shown with fixed rates (0-100, 100-512,​512-2048,​2048-4096,>​4096 Mbit/s) on it's line-width/​weight. 
 +   * Filtering of netboxes based on categories. These categories are set from the categories you have in the database.  
 +   * Filtering orphans (netboxes not linking to anything)  
 +     * Note: elink is a fictive category, and Netmap itself detects where the elink should be based on NAV's known topology.  
 +     * Note2: can't save metadata / positions of elink nodes, since there is no relation to them as it is a fictive node.  
 +   * Searching. One can search after netboxes based on sysname 
 +   * Option to pause the layout engine to preserve cpu-load. This should not be needed as the layout engine should stabilize the graph rather quickly in a newer browser and modern PC. In case your living in the past, there'​s an option to pause it ;-) 
 +   * Toggle sidebars by a click of a mouse button.  
 +   * Toggle '​fullscreen'​ by clicking CTRL+SHIFT+F (hides sidebars and NAVs header and footer) 
 +   * Mark nodes located in same room or location as the selected node.  
 +   * Fix or unfix all node positions. (this is position metadata that is saved to a view) 
 +   * Views 
 +     * User specific views and possibility to share em among other users 
 +     * Delete your own views 
 +     * Update current view 
 +     * Create new view from selected view (incase you want a modify a view that isn't yours) 
 +     * Select a favorite view 
 +     * Administrator can set a global favorite view for users who does not have an favorite view selected. 
 +   * Different info templates for selected netbox or selected link.  
 +   * Traffic gradient popup (will be nice when RRD/traffic load is refreshed every x min.  
 +   * Show topology errors (mark links/​nodes) red if there'​s something unusual in your network topology. ie, different interface speeds between the links can cause to network congestion 
 +   * Mouse over UI actions, «Auto-clicks» a node or link by simply hoovering em.
-A small plundering from Kristian Klette about the new netmap ​(In norwegian):+NOTE: Icons for the following categories are included GSW, GW, OTHER, SRV, SW, WLAN, EDGE and the fictive category ELINK. If you have other categories, put an icon with the category name in  
 +$NAV_ROOT/​share/​htdocs/​images/​netmap/ in the png format. Noteuse lower case filename of the category name. 
-Formål: +===== Brief user guide=====
- En dynamisk fremvisningsverktøy for nettverk, både på VLAN- og LAN-nivå. +
- Det skal være mulig å se noe statistikk for for enhetene som ligger i systemet, men +
- det skal ikke være mulig å gjøre endringer via dette verktøyet, _kun_ overvåking.+
-Krav: +The netmap is available from the toolbox.
- > På alle fremvisninger skal det være mulige å se på detaljer om en enhet ved å klikke på noden. +
-   Det skal da vises frem en "​sidebar"​ med informasjon (og muligens grafer) om tilgjengelig informasjon +
-   tatt fra RRD-dataene vi har i databasen. Grafene vil så fremt det er mulig bli generert på serversiden,​ da +
-   Java har en mangel på gode RRD-bibliotek.+
- > Det skal være mulig å flytte på noder i grafenmen disse valgene vil ikke kunne lagres til neste gang, +Netmap consists of two navigation barsone on each side of the screenand the map itself. The navigation bars can be toggled by clicking the "<<"​ or ">>"​ links. ​ You can toggle fullscreen with CTRL+SHIFT+F.
-   (da er vi tilbake på VLanPlot-nivå igjen).+
- > Alle fremvisninger skal kunne søkes i ved hjelp av et fritekstsøk+The load colors((Click "Show gradient"​ to get an overview of what the colors indicate)) on edges represent traffic load based on the link's capacity, and the link's thickness represents the link speed.  
-   Man kan også vurdere å ha mulighet for å søke etter MAC-adresser og lignende, men dette er en lavt prioritert +==== Map ====
-   oppgave.+
- > Det skal være mulig å dra ut "​ugyldige"​ noder fra grafenog så bygge treet på nyttDette er nyttig hvis man +  * Nodes can be positioned to your liking by clicking and dragging it. 
-   vil redusere overvåkingen av et nettverk til noen få enheter.+  * To view information about a node or a linkjust click on it
 +  * You may zoom the map by using the scroll-wheel on your mouse.
- > Man skal kunne bygge grafer basert på typen enheter, med andre filtreringsegenskaper. (Filtrere basert på linktype o.l.) 
- > VLAN fremvisningen vil være basert på et klyngedesign e.l. (f.eks ForceDirectedLayout),​ men vil ta i bruk koordinater +==== Left navigation bar ====
-   hvis disse er tilgjengelige.+
- > LAN fremvisningen vil være basert på en mer fast trestruktur. Denne vil basert på prefuse sin TreeLayout, men sortere ting +The left navigation bar has options for filtering and controlling the behaviour of the map.
-   etter klynger med like enheter osv.+
-Info: +=== Searchbox ===
- Fremvisning på VLAN nivå vil ikke nødvendigvis være topologisk korrekt grunnet manglende +
- data fra NAV-databasen (manage). Dette er et problem som burde bli løst på innsamlingsnivå (getDeviceData),​ +
- og ikke i fremvisningen. Fremvisningen vil dog bruke lokasjons-koordinater hvis disse finnes på de aktuelle +
- ruterne. VLAN vil bli vist frem som en klynge, sortert, om mulig, på siden koordinater. Ved HSRP-enheter vil +
- de bli vist som én enhet sammen med sin masternode.+
- Fremvisning på LAN-nivå skal være så langt det er mulig topologisk korrektFremvisningen skal ha mulighet +This searches for the name of a netbox and centers the map on itIf the search hits several netboxes the map will center on the first.
- å sette deler av nett i "​skygge"​ om nødvendig.+
- Ved et lite antall enheter som overvåkes ​(f.eks kun ett lokalt nettverkvil+=== Zoom to extent === 
 +Zoom to extent will try to position the whole graph in the center of the view port and scale out so you can see it. 
 +=== Layer box === 
 +Toggle if you want to see layer 2 or layer 3 topology ​(([[http://​​wiki/​OSI_model|OSI model]])). 
 +=== Categories === 
 +Choose what categories of netboxes you want to see. 
 +=== Filter options === 
 +  * **Filter orphans**: Uncheck this to hide nodes with no links to other nodes. 
 +  * **Mark by position**: Mark nodes that are located in the same room or location. This is shown by drawing a red circle around the nodes who are related to the selected node. 
 +  * **Pause force algorithm**:​ Pause the layout algorithm by clicking the button. A green icon indicates active algorithma red an inactive algorithm. Resume it by drag and dropping a node, unfix a node, unfix all nodes or clicking the button again. 
 +  * **Fix or unfix all nodes**: Set all nodes to fixed or unfixed. Fixed nodes will not move when running the algoritm. 
 +=== UI options === 
 +  * **Show topology errors**: for instance mark links with differing speed set on the netbox inerfaces 
 +  * **Mouseover options**: Enable or disable auto selection when hovering a link or node. This can also be toggled with the keyboard shortcuts «n» or «l» (lowercase of L).  
 +=== Traffic gradient === 
 +Open the traffic load scale used in netmap in a popup.  
 +==== Right navigation bar ==== 
 +=== Available views === 
 +A drop down / combi box which shows your available views. Your own views are listed at the top and public views are listed below it.  
 +The selected view is always rendered as the first choice in the drop down. 
 +If the view has a description,​ it will be shown below the "​Save"​ and "​Favorite"​ buttons.  
 +The save button is a button for updating changes to a selected view, if the view isn't saved it will trigger a "Save new as".  
 +You probably also noticed the "​+"​ and "​-"​ buttons on the right side, the "​+"​ button is always known as "Save new as" and the "​-"​ button is known for "​Delete active view". Careful, there is no confirmation dialog when deleting a view and as an administrator you are allowed to delete any view! 
 +A heart will popup if the selected view is the user's favorite view.  
 += Save new view = 
 +Popups up a modal form, where you can enter title for the view (shown in dropdown) and a longer description if that is needed. 
 +A checkbox is available to select if the view should be open for other users in netmap or private.  
 +== Map info == 
 +This is the view that will render with a Netbox or Link template for a selected netbox or link. If your an administrator,​ a link to the administration area will be available at the bottom here.  
 +Depending on which network topology layer you have active, it will render a bit different information.  
 +== Netbox view == 
 +Renders the sysname and it's management IP first together with the "​pping"​ indicator of the netbox is up or down. (this is atm only loaded at network topology graph load, in the future this will automagically refresh) 
 +A checkbox for knowing if the node's position is fixed or unfixed in the graph. Fixed positions is what get's saved when your saving a view.  
 +Category is the netbox'​s category.  
 +(Missing atm: Device type ;-( )  
 +Room and location information.  
 +If layer2, render VLAN information and option to select a vlan. When clicking on a VLAN, it will mark other nodes and links that is member of the current VLAN in it's broadcast domain.  
 +== Link view == 
 +If layer3, render netident and netdescription together with active prefixes over this link.  
 +Renders from  netbox [interface] to netbox [interface] 
 +Link speed of the link. 
 +Traffic in and out. (from: in  , out: to)  
 +Example: netbox A and B, a is listed first. That means you will read it like this:  netbox A A is receiving 200mbps in and transfers 400mbps out to B.  
 +===== Troubleshooting ===== 
 +1. Rendering is horrible slow 
 +This kind of problem can be two things (or both). Using an old outdated browser with poor javascript performance or having a old computer. (the layout algorithm is quite CPU intensive). 
 +Chrome is known to have the best javascript engine, so we recommend the use of chrome webbrowser. ​
