We have a couple of apps running under Microsoft Azure Cloud Web Roles for about a year and a half now.
We have Azure Diagnostics setup to capture perfdata, events and IIS logs (to blob storage).
At the end of the year we rolled out a build that was using the new Azure SDK (2.5). The first thing we noticed was we had to push out the diagnostics setting through Visual Studio as all of our diagnostics stopped flowing. This seemed to work okay however periodically the new IIS logs just stop appearing in blob storage. Sometimes just updating the diagnostics settings for the web role seems to fix things, however sometimes I have to restart the instance for IIS logs to start flowing again.
I see in our project we still have the old diagnostics config file plus the new version diagnostics.wadcfgx (however the storage account doesn't appear to be set on it so I don't know if it's being used?).
At this point I am not quite sure where to begin to troubleshoot this condition? We have determined the timing of the log stoppage does not seem to be related to our timing of our application deployments so I am not sure what event could be causing it?
Any ideas what I should be looking for to troubleshoot this condition?
Thanks,
