TMWS on-premises gateway preserves raw logs locally and uploads log statistics to TMWS cloud for dashboard widget and report generation. Raw logs are sent to cloud only when users conduct (on-demand) raw log query on cloud console. That is, when on-premises gateway is disconnected from network, raw log query in cloud console will not successfully retrieve any on-premises log data.
If users do not want to upload on-premises gateway logs to TMWS cloud, they could turn it off in Logs & Reports settings.
This switch controls both raw logs and log statistics. So when it is turned off, TMWS cloud console will not be able to show log statistics or generates report for on-premises gateway. Users may configure syslog forwarding to export on-premises gateway logs to their own SIEM or log system to process further.
