Overview: Mark Russinovich and Thomas Garnier join Andrew Richards in this episode of Defrag Tools. We talk about their new tool - Sysinternals System Monitor. System Monitor (Sysmon) is a Windows system service and device driver that, once installed on a system, remains resident across system reboots to monitor and log system activity to the Windows event log. It provides detailed information about process creations, network connections, and changes to file creation time.
