There are very few log files to troubleshoot CMG issues however you must know the location of those cloud management gateway log files. They are either located on site server or on Azure server.

In my previous post I covered on steps to enable remote desktop in CMG. If you enable the remote desktop in SCCM CMG, you can access the CMG log files easily. To setup SCCM CMG from scratch, refer this post –

5 thoughts on “SCCM CMG Log Files for Troubleshooting”

  1. Anything logged client side? My clients aren’t talking to the CMG and I can’t figure out why.

  2. cuando tengo implementado IBCM e implemento CMG como obligo al cliente a que use CMG en lugar de IBCM.

  3. The logs on the site server could be in a different location if SCCM was not installed to the default location on the C drive. To find the logs, the path would be “<SCCM installation directory\Logs" such as "E:\Microsoft Configuration Manager\Logs" or they could be found by using the SMS_Sitecode share such as "\\CMServer\SMS_USA\Logs"
