For the last several months Pete Zerger, Tao Yang, Kevin Greene, Anders Bengtsson and me have been working hard to update Inside OMS book. With the latest changes we are now on version 3 of the book and with new name: Inside Azure Management

Log Analytics alerts aka Azure Log Search Alerts allows you to create a single alert and trigger alert instances per a column. This is possible by creating metric measurement alert. Unfortunately these types of alerts also have a limitation which might be blocking in certain situation. The classical example for that limitation is to create a single alert that will separate instance for free disk space threshold for each computer and disk. The query representation of that looks like this:
