IIS Event Source

Hello There,
I have multiple IIS servers and I want to combine like 10 IIS servers and ship the logs to one directory so that I can set a watch directory in IDR to capture all the logs under one event source. I have created a shared folder but the logs are not being written to the shared folder. I am able to manually copy a sample of the log from the local IIS server to the network share so I think is not a permission issue. Can anyone help me on how I can make sure logs are written to the path I specified on the W3C logging? Thank you!

Also if anyone have done this before, I am opened to any other method that is working for you. But essentially, I dont want to set an event source per IIS server
