I have a node.js api app on azure. I use bunyan to log every request to sdtout. How can I save and read the log files? I enabled BLOB-logging. The only thing that shows up in my storage is a bunch of csv-files. Here is an example:
| date | level | applicationName | instanceId | eventId | pid | tid | message
_______________________________________________________________________________________________________________________________________________________________

Where are my logs, that I printed to stdout?
1) Create file iisnode.yml in your root folder (D:\home\site\wwwroot) if not exists.
2) Add the following lines to it.
loggingEnabled: true
logDirectory: iisnode
After that done, you can find logs in D:\home\site\wwwroot\iisnode.
For more info, please refer to https://docs.microsoft.com/en-us/azure/app-service-web/web-sites-nodejs-debug#enable-logging.
After above settings in iisnode.yml, the logs you see D:\home\site\wwwroot\iisnode are from BLOB storage or file system.
