Sorting by column headings is fine, but I wonder if as Andy says filters is what we want. What are the chances that what you're looking for will be at the top and easier to find. Better grouping might be a better a design. Put all the same type of alerts together for example.
Also, does having one long page help anyone? Who is going scroll from A to find the Rs for example? In large consoles much better to search
