Adjust Index Defragmentation

Hi....

This is regarding Index Defragmentation I wonder how to adjust the number of index pages which will be monitored by Solarwind . For example : I notice that indexed which has 100 pages and above will be catched by Solarwind and display the status ( Critical or Warning ) for the index fragmentation . but I want Solarwind only catched indexes which have pages more than 1000 . if below 1000 then they wouldn't be cared So how to adjust it ?

Thanks so much !

Cheers
