Strategies for Capture

  • VMware Identity Manager Linux Virtual Appliance: For a virtual appliance, the metrics are captured by the underlying virtual infrastructure utilizing tools such as vSphere or vRealize Operations.

  • VMware Identity Manager on Windows: Install a monitoring agent that is supported for Windows servers and can capture these metrics. Additionally, for virtual servers, you can use tools native to vSphere to capture the relevant metrics.
