Lock Wait

Time spent waiting for blocking locks to be released.

Log Buffer Wait

Time spent by the various sessions waiting for space in the log buffer or otherwise waiting for memory to be made available to write log records. Consistently high values of this metric can indicate the log devices’ inability to keep up with the amount of log generated by the server.

Logical Reads

A logical read occurs every time the Database Engine requests a page from the buffer cache.

LRU

Least Recently Used. Often refers to pages in memory. The LRU list is the mechanism by which Azure SQL Database determines which pages should be moved to the free list first.
