eG Help

In most VDI environments, it is essential to monitor the uptime of virtual desktops hosting critical applications in the infrastructure. By tracking the uptime of each of the virtual desktops, administrators can determine what percentage of time a virtual desktop has been up. Comparing this value with service level targets, administrators can determine the most trouble-prone areas of the VDI infrastructure.

In some environments, administrators may schedule periodic reboots of their virtual desktops. By knowing that a specific desktop has been up for an unusually long time, an administrator may come to know that the scheduled reboot task is not working on a desktop.

This test included in the eG agent monitors the uptime of a chosen Session Host / Azure virtual desktop.

This page depicts the default parameters that need to be configured for the WVDUptimeTest.

Outputs of the test : One set of results for the chosen Session Host / Azure Virtual Desktop.

Measurement	Description	Measurement Unit	Interpretation
Rebooted	Indicates whether the target virtual desktop has been rebooted during the last measurement period or not.	Boolean	If this measure shows 1, it means that the virtual desktop was rebooted during the last measurement period. By checking the time periods when this metric changes from 0 to 1, an administrator can determine the times when this virtual desktop was rebooted. If the Has system been rebooted? measure reports the value 1, then you can use the detailed diagnosis of the measure to know more about the last desktop reboot/shutdown. When the reboot occurred last, when the desktop was shutdown last, and the duration of the shutdown is reported as part of detailed metrics. From this information, administrators can figure out if the reboot/shutdown was scheduled or unscheduled.
Uptime	Indicates the time period that the virtual desktop has been up since the last time this test ran.	Secs	If the virtual desktop has not been rebooted during the last measurement period and the agent has been running continuously, this value will be equal to the measurement period. If the virtual desktop was rebooted during the last measurement period, this value will be less than the measurement period of the test. For example, if the measurement period is 300 secs, and if the virtual desktop was rebooted 120 secs back, this metric will report a value of 120 seconds. The accuracy of this metric is dependent on the measurement period - the smaller the measurement period, greater the accuracy.
Segment Total_uptime	Indicates the total time that the virtual desktop has been up since its last reboot.	Mins	Administrators may wish to be alerted if a virtual desktop has been running without a reboot for a very long period. Setting a threshold for this metric allows administrators to determine such conditions.
