How do I solve performance issues when collecting metrics with the Windows Standalone Machine Agent?
Some users have experienced slow performance and/or high resource consumption when collecting server metrics on Windows with Server Visibility enabled.
The ServerMonitoring extension uses the Windows Monitoring Interface (WMI) to collect metrics on Windows machines. If you experience problems using WMI, you can configure the ServerMonitoring extension to use SIGAR instead. The trade-off is that SIGAR cannot collect all the metrics that WMI can. See Metrics Not Available When Using SIGAR for the list. In addition, this solution is available only on version 4.3.8 (or higher) of the Standalone Machine Agent.
To use SIGAR, specify the following System Property on the agent (the default is
-Dappdynamics.machine.agent.extensions.sim.sigarCollectorEnabled = true
f you use SIGAR (not WMI) with the ServerMonitoring extension, the following metrics will be unavailable.
