Indexes
Initially Mini DBA displays total index usage data as seen below. It tells you how many times types of operation have been performed on the index and the last time at which these operations occured.
The Current Usage tab is a live updating grid that displays index usage as it happens. This is highly useful when diagnosing what indexes slow operations are actually using. The grid can be paused to keep results on the screen for analysis.
The storage details tab shows heatmap graph, which displays each index sized on its storage and coloured by fragmentation %. Using the combination of the size and the color of the index it is possible to start making a decision on how important the fragmentation is for that index.
Detailed information is given in tooltips for each index.
When the storage/fragmentation grid is selected more detailed information around partitions size, fragmentation and statistics age is displayed which can be sorted by clicking column headers.
Unused (indexes that have not been used since server restart or the database was restored) and missing index (indexes that may be helpful) information can be seen under the other 2 tabs.
