Approach and mechanism for calculating and configuring memory mapping of trend log objects in a system

A method for trending with information about available memory, comprising:

• exposing, via a controller, raw memory of the controller for a configuration of a trend by calculating available records in view of total available memory of the controller, and one or more items of a group incorporating buffer size, log interval and retention time, when a trend object is created;
• and
• automatically recalculating, via the controller, available records when one or more items of the group comprising buffer size, log interval and retention time, are affected or changed;
• and
• wherein one can allocate memory to trend configurations.

A mechanism for determining memory for trending, comprising:

• a controller having a processor and a memory;
• and
• wherein:
• the processor calculates available records in view of a total amount of the memory of the controller;
• a calculation of the available records considers impacting parameters of buffer size, log interval and retention time, when a trend object is created;
• and
• a recalculation of available records occurs when one or more of the impacting parameters are changed.
