When working with PHP on Windows Azure, chances are you may want to have a look at what’s going on: log files, crash dumps, performance counters, … All this is valuable information when investigating application issues or doing performance tuning. Windows Azure is slightly different in diagnostics from a regular web application. Usually, you log into a machine via remote desktop or SSH and inspect the log files: management tools (remote desktop or SSH) and data (log files) are all on the same machine. This approach also works with 2 machines, maybe even with 3. However on Windows Azure, you may scale beyond that and have a hard time looking into what is happening in your application if you would have to use the above approach. A solution for this? Meet the Diagnostics Monitor.
