The Microsoft Exchange Server Monitoring Log Enablement Package (LEP) is a Windows Performance Monitor Template which contains Performance Counters. These counters provide basic threshold monitoring of Microsoft Exchange Server Performance Objects like Outlook Web App(OWA) and MSExchange Availability Service. All threshold data are sent to the Application Event Logs where the K1's Agent or Agentless component can manage performance data extraction. K1 then displays this data in a single page UI which tracks the overall health of the endpoints being monitored. The Threshold column below displays a Criteria Level of Critical, Warning, or Error. This column should have two values, a Default value and a Threshold value, for records without both, only a Default value of 10000 is set which needs to be reset to an appropriate Threshold value. For instructions related to LEP's check out How to Edit Windows Monitoring Log Enablement Package (LEP), How to Import Windows Monitoring Log Enablement Package (LEP) and Troubleshooting Windows Monitoring Log Enablement Package (LEP). Detailed instructions on how to configure the K1 to monitor Application or Threshold Monitoring on devices can be found in the Dell KACE K1000 System Management Appliance 6.3 Administrator Guide.
