 # Racks
 
-Within each site exist one or more racks. Each rack within NetBox represents a physical two- or four-post equipment rack in which equipment is mounted.

 Every piece of hardware which is installed within a rack exists in NetBox as a device. Devices are measured in rack units (U) and depth. 0U devices which can be installed in a rack but don't consume vertical rack space (such as a vertically-mounted power distribution unit) can also be defined.

+When assigning a multi-U device to a rack, it is considered to be mounted in the lowest-numbered rack unit which it occupies. For example, a 3U device which occupies U8 through U10 shows as being mounted in U8. This logic applies to racks with both ascending and descending unit numbering.
 
 A device is said to be "full depth" if its installation on one rack face prevents the installation of any other device on the opposite face within the same rack unit(s). This could be either because the device is physically too deep to allow a device behind it, or because the installation of an opposing device would impede air flow.
 
 ### Roles
 
-NetBox allows for the definition of arbitrary device roles by which devices can be organized. For example, you might create roles for core switches, distribution switches, and access switches. In the interest of simplicity, device can only belong to one device role.

 Device bays represent the ability of a device to house child devices. For example, you might install four blade servers into a 2U chassis.

Child devices do not appear on rack elevations, but they are included in the "Non-Racked Devices" list within the rack view.

 However, some users might want to associate with objects attributes that are somewhat esoteric in nature, and that would not make sense to include in the core NetBox database schema. For instance, suppose your organization needs to associate each device with a ticket number pointing to the support ticket that was opened to have it installed.

+NetBox does not have the ability to generate graphs natively, but this feature allows you to embed contextual graphs from an external resources (such as a monitoring system) inside the site, provider, and interface views. Each embedded graph must be defined with the following parameters:

+* **Type:** Site, provider, or interface. This determines in which view the graph will be displayed.
 * **Weight:** Determines the order in which graphs are displayed (lower weights are displayed first). Graphs with equal weights will be ordered alphabetically by name.
 * **Name:** The title to display above the graph.
 * **Source URL:** The source of the image to be embedded. The associated object will be available as a template variable named `obj`.
 * **Link URL (optional):** A URL to which the graph will be linked. The associated object will be available as a template variable named `obj`.
 
+## Examples
+
+You only need to define one graph object for each graph you want to include when viewing an object. For example, if you want to include a graph of traffic through an interface over the past five minutes, your graph source might looks like this:
+
+```
+https://my.nms.local/graphs/?node={{ obj.device.name }}&interface={{ obj.name }}&duration=5m
+```
+
+You can define several graphs to provide multiple contexts when viewing an object. For example:
+
+```
+https://my.nms.local/graphs/?type=throughput&node={{ obj.device.name }}&interface={{ obj.name }}&duration=60m
+https://my.nms.local/graphs/?type=throughput&node={{ obj.device.name }}&interface={{ obj.name }}&duration=24h

 # Topology Maps
 
 NetBox can generate simple topology maps from the physical network connections recorded in its database. First, you'll need to create a topology map definition under the admin UI at Extras > Topology Maps.
 
-Each topology map is associated with a site. A site can have multiple topology maps, which might each illustrate a different aspect of its infrastructure (for example, production versus backend connectivity).
+Each topology map is associated with a site. A site can have multiple topology maps, which might each illustrate a different aspect of its infrastructure (for example, production versus backend infrastructure).
 
 To define the scope of a topology map, decide which devices you want to include. The map will only include interface connections with both points terminated on an included device. Specify the devices to include in the **device patterns** field by entering a list of [regular expressions](https://en.wikipedia.org/wiki/Regular_expression) matching device names. For example, if you wanted to include "mgmt-switch1" through "mgmt-switch99", you might use the regex `mgmt-switch\d+`.

 The root of the IPv4 hierarchy is 0.0.0.0/0, which encompasses all possible IPv4 addresses (and similarly, ::/0 for IPv6). However, even the largest organizations use only a small fraction of the global address space. Therefore, it makes sense to track in NetBox only the address space which is of interest to your organization.
 
-Aggregates serve as arbitrary top-level nodes in the IP space hierarchy. They allow you to easily construct your IP scheme without any clutter of unused address space.

 ### RIRs
 
 Regional Internet Registries (RIRs) are responsible for the allocation of global address space. The five RIRs are ARIN, RIPE, APNIC, LACNIC, and AFRINIC. However, some address space has been set aside for private or internal use only, such as defined in RFCs 1918 and 6598. NetBox considers these RFCs as a sort of RIR as well; that is, an authority which "owns" certain address space.
