A Trend Log object saves a record of a physical or virtual object’s behavior so you can monitor changes to the object over time. The purpose of a Trend Log is to provide historical data about an object’s performance.
Trend objects can be created by clicking 
next to any trendable object or by using the Templates application. Use this procedure to create a Trend Log object with a template.
