====Alerts====

As well as [[properties|properties]] and [[relationships|relationships]], ARDI also has a list of //alerts// attached to each asset.

In most visualisations, alerts are clearly displayed. 

===Upstream Alerts===

Because ARDI understands how your assets are physically connected, many of our visualisations can let you know if the asset has an //upstream alert//. These are alerts that are currently active on any assets that appears 'before' the current asset in any relationship.

Let's imagine you have a room temperature sensor, connected to a large digital display. If someone was told to try and repair that particular asset, they might think the display was dead when it appeared blank.

However, if they used [[ARDI-AR]] or viewed the [[Web Dashboard]], they'd see that the device has an upstream alert - the power supply for the display is currently turned off for maintenance.
