The Health Scan tool allows you to monitor application of VM changes that may compromise the port access, performance, or overall access by end users to the desktop.

Procedure

  1. Install the Horizon DaaS Health Agent on all VMs that will be monitored. Click the Install Horizon DaaS Health Agent link at the top right of the VM Health Scan tab for more information.
    Note:

    By default, the Health Agent listens on TCP port 10762.

  2. Filter the list as desired using the Scan Filter field and/or Select Pool drop-down list.
  3. Initiate the scan by doing one of the following:
    • Click One Time Scan to perform a single scan immediately.

    • Enter a number of minutes and click Schedule Scan to schedule recurring scans at a selected time interval.

    Information for the scanned VMs appears in columns as described below.

    Name of the virtual machine.

    Pool

    Pool (assignment) to which the VM belongs.

    IP address of the VM.

    Result

    Overall result of the scan. Result can be:

    • Power off – VM is powered off.

    • Agent failure – Health Agent is not installed or reachable on the VM

    Verifies that RDP is enabled and set to allow connections from computers running any version of RDP.

    BAD IP

    Verifies that the desktop does not have a 169.x.x.x IP address, and so is more likely to get DHCP.

    Domain Trust Relationship

    Confirms domain trust relationship between desktop and Domain Controller.
