Desktop OS Session Physical Memory Utilization (Alert)

Summary

Helps to identify Desktop OS sessions that host memory hungry applications/processes.

Configuration

The following configuration parameters are customizable:

Formula for ConsolidationInterval:

ConsolidationInterval = ((NumberOfSamples - 1) * IntervalSeconds ) * 1.1

Example for monitor to generate alert only when monitored value is above threshold for 20 minutes (4 consecutive samples):

IntervalSeconds = 300 (5 minutes) NumberOfSamples = 4 ( 20 minutes / 5 minutes = 4) ConsolidationInterval = ((4 - 1) * 300) * 1.1 = 990

Resolutions

Troubleshooting

Identify the processes/services consuming memory using Citrix Director (Alert Task: Start Citrix Director) or Task Manager or Resource Monitor locally on the machine.

• If all processes/services work within normal parameters and the level of memory consumption is as expected, consider adding additional memory to this system in the future.

• If a process/service that works outside normal parameters can be identified, the process should be killed. Please note that killing a process can cause unsaved data to be lost.

Additional

In addition to alert description, some information is also available in Alert Context tab:

• DateTime - Date and time when the data was gathered.

• SiteName - Name of the site.

• DeliveryGroupName - Name of the delivery group of machine hosting the session.

• MachineName - Host name of the machine hosting the session.

• VDAVersion - Version of the Citrix Virtual Delivery Agent (VDA) installed on the machine.

• HypervisorName - Hostname of the machine’s hypervisor (for virtual machines only).

• MachineOSType - Identifies the operating system that is running on the machine.

• User - Name of the user connected to the desktop or application.

• SessionStart - Date and time value indicating the start time of the session.

• SessionType - Indicates if this is an Application or Desktop session.

• SessionState - Indicates the state of the session.

• SessionKey - Citrix unique identifier for this session.

• CPU - CPU utilization of Desktop OS machine.

• PhysicalMem/PhysicalMemUtil - Values indicating physical memory usage, in MB and percentage.

• VirtualMem/VirtualMemUtil - Values indicating virtual memory usage, in MB and percentage.

• PageFaultsPerSec - Memory hard page faults per second for Desktop OS machine.

• NetworkReceive/NetworkSend – Desktop OS machine’s network receive/send values in KBps.

• NetworkTraffic - Desktop OS machine’s network bandwidth consumption (send and receive) in KBps.

• DiskIOPS - Rate of read and write operations on disk per second.

• DiskRead/DiskWrite - Disk read/write values in KBps.

• DiskQueue - Disk queue length.

• DiskLatency - Disk latency in milliseconds.

• SessionInput – Citrix session input bandwidth used (KBps). It includes all session traffic from Citrix Receiver to VDA machine.

• SessionOutput – Citrix session output bandwidth used (KBps). It includes all the session traffic from VDA machine to Citrix Receiver.

• SessionBandwidthUsage – Citrix session bandwidth used (KBps). It includes all the session traffic from VDA machine to Citrix Receiver and in opposite direction.

• SessionLatency – Network latency detected between the Citrix Receiver and the VDA machine (ms).

• SessionRTT – ICA Round Trip Time (ms). The time interval measured at the client between the first step (user action) and the last step (graphical response displayed).

• Applications – List of application in use.
