On Prem Data Gateway Performance Logs

[tayloramy]

Hi Fabric Community, 

I have a handful of on prem data gateways, and I'm seeing some strange behaviour. I have 5 gateways, 3 of which are standalone and 2 are in a cluster. 

All gateways are standard gateways, not personal. 

2 of the standalone gateways are producing performance logs in the log folder, but the other three gateways are not. 

The gateways are all on the same version, and were installed with the same settings. I have verified the configuration settings outlined in here: Monitor and optimize on-premises data gateway performance | Microsoft Learn

I am at a loss as to why the gateway performance logs aren't being generated. 

The gateways are running under specific accounts, not the default service account. I have checked the log file location for the gateway account and the default PBIEgwService account. Gateway logs in general are being generated, but no performance logs in the Report folder. 

Does anyone have any ideas?

Hi @tayloramy 

The solution for On-Premises Data Gateway not generating Performance Logs is:

Enable Performance Logging in the Gateway Configuration Manager under Diagnostics/Logging.

Ensure the gateway service account (custom or PBIEgwService) has Full Control over the Performance Logs folder:

C:\Users\<GatewayAccount>\AppData\Local\Microsoft\On-premises data gateway\GatewayPerformanceLogs

Verify all gateways are updated to the latest On-Premises Data Gateway version.

For clustered gateways, check the primary node, as secondary nodes may not generate independent logs.

Restart the gateway service after any changes to settings or permissions.

Check Event Viewer or general gateway logs for errors if performance logs still do not appear.

The issue is usually caused by permissions, disabled logging, or wrong folder path. Correcting these and restarting the service should resolve it.

If this helps, consider giving some Kudos. If I answered your question, please mark this as the solution.

Hi @Rufyda, 
Under Diagnostics, there is no performance logging: 
 

I can confirm that the service account has full access to all folders. 

The gateways are all on the August 2025 version:

Since Performance Logging may be moved or renamed in the August 2025 version:
Check the Tracing folder:

C:\Users\<GatewayAccount>\AppData\Local\Microsoft\On-premises data gateway\Tracing

For clustered gateways, review the primary node only.

If still missing, contact Microsoft support with your gateway version and account details.

This should help access performance metrics even if the Diagnostics option isn’t visible.

Hi @Rufyda, 

There is no Tracing folder on any of my gateways.
