Logging one file for each day in Azure

This is related to Sitecore logging using log4net in Azure.

Current Behavior:

  1. Multiple files getting created for the day.
  2. The last file of the day is always of a different format(I have tried date tag to resolve..still its not working as expected)

Below are the three screenshots:

The log4net related setting just for azure enter image description here

The only change which I have added at the moment. enter image description here

Multiple files created for 20 Oct(i.e today) and last night file with weird name. enter image description here

Expected behavior: I want to log one file for each day irrespective of the number of restarts/application pool recycle with the date in the name of the file.

  1. Just one file with date in the name included (eg.azure.log.20221020.084617.txt)
Solution

  • An update please, this error got resolved after I used the below code to resolve:
