====Alert Attachment====

Alerts are **atttached** to assets in your ARDI database.

There are several different methods of attachment...

===Direct / Asset Attachment===

In this case, your alert is attached directly to a single, named asset.

===Type Attachment===

Your alert will be attached to **every asset of a particular type**.

This is usually used when there's an alert (or an alert threshold) particular to a single type of asset in your ARDI system.

===Property Attachment===

Your alert will be attached to **every asset that shares all of a particular set of properties**.

This is useful if you have different assets with similar control limits, but they don't share a type. They're most commonly used for control limits and speed thresholds - for instance, by attaching an out-of-control alert to any asset that has both a //target// and an //actual// speed.

===Relationship Attachment===

This attaches an alert to **the nominated asset, plus every asset found down-stream from it** along a specific relationship.

This is useful when you want to deploy an alert across a set of assets, particularly if you're looking for discontinuities, leaks or other asset-to-asset changes.
