^Option^Description^
|Name|The name should be relatively short, but meaningful.|
|Description|A longer description of the issue and possibly any guesses to its cause|
|Type|Some alerts relate to a particular relationship - ie. an alert about low power will be associated with the //power supply// relationship. If one is appropriate, choose it here.|
|Media|If the alert has troubleshooting instructions or can usually be resolved with documented instructions, choose those instructions here.|
|Alert Based On|See Below|
|Trigger Alert When|Hidden by default. See below|

===Alert Conditions===

There are two options for //Alert Based On// which control how your alert is generated.

If the value for 'Alert Based On' is **A Data Source**, then the alert itself is being generated in your system. You can use [[data linking|data linking]] to connect your live or historical data to that point. This is ARDIs //preferred// method, as it makes historical replays of your information more accurate.

If the option is **A Property Value**, then ARDI itself generates the alert by inspecting the incoming data values. This is //not// ideal, as historical alerts may not be available in all clients.

===Property Value Conditions===

When the option for //Alert Based On// is **A Property Value**, the 'Trigger Alert When' section will be available.

Here, you can choose a property, a comparison and a number that must be met in order for the alert to be raised.

==Low Alarm Example==

To raise an alert when a tank is starting to run out of liquid (ie. lower than 10%), you could create an alert that has the following options...

^Option^Value^
|Alert Based On|A Property Value|
|Trigger (#1)|Level|
|Trigger (#2)|Is Less Than|
|Trigger (#3)|10|

==Deleting Alerts==

Alerts can be deleted from the [[ardiadminguide:detail_alerts]] page, by pressing the trashcan icon next to the alert you'd like to dispose of.
