VMware View 5 PCoIP Session Statistics (WMI)
VMware View 5.0 exposes Teradici’s PCoIP session statistics through the WMI interface. Before View 5.0 the only mechanism to identify bandwidth usage and allocation was trough the log files. The log files are still a good source and there are few good applications that will consolidate log files and demonstrate the broad PCoIP utilization and network conditions in your organization. Please refer to App for PCoIP Real-Time Monitoring across your Organisation.
The PCoIP Session statistics are available virtual desktops running VMware View agent 5.0 and can be retrieved from the host VM utilizing PerfMon.
The PCoIP statistics are grouped within the following name spaces:
- PCoIP Session General Statistics
- PCoIP Session Network Statistics
- PCoIP Session Audio Statistics
- PCoIP Session Imaging Statistics
- PCoIP Session USB Statistics
After a PCoIP session is closed, all the statistics are reset to zero. If the WMI property SessionDurationSeconds is a non-zero value and if it stays the same, it means PCoIP server has been forcefully ended or crashed. If SessionDurationSeconds changes from non-zero to zero value, it means PCoIP session has been closed.
The PCoIP Session Statistics are updated every second.
WMI Namespace: root\CIMV2
For automation of management task such as querying for management data, execution of a method from a WMI class, or receiving event notifications using WMI it possible to create scripts in VBScript, C#, and VB .NET using “WMI Code Creator” from Microsoft.

| Round Trip Latency ms | Round trip latency (in milliseconds) between server and client. | RoundTripLatencyms |
| RX BW kbit/sec | Overall bandwidth for incoming PCoIP packets averaged over the sampling period (in seconds). | To calculate bandwidth:
(BytesReceivedsample2 – BytesReceivedsample1) x 8 / 1024 / SamplePeriod |
| RX BW Peak kbit/sec | Peak bandwidth for incoming PCoIP packets within a one second sampling period. | RXBWPeakkbitPersec |
| RX Packet Loss % | Percentage of received packets lost during a sampling period. | To calculate packet loss:
?PacketReceived = PacketsReceivedsample2 – PacketsReceivedsample1 ?RXPacketsLost = RXPacketsLostsample2 – RXPacketsLostsample1) RXPacketLoss % = ?RXPacketsLost / (?RXPacketsLost + ?PacketReceived ) x 100 |
| TX BW kbit/sec | Overall bandwidth for outgoing PCoIP packets averaged over the sampling period (in seconds). | To calculate bandwidth:
(BytesSentsample2 – BytesSentsample1) x 8 / 1024 / SamplePeriod |
| TX BW Active Limit kbit/sec | The current estimate of the available network bandwidth, updated every second. | TXBWActiveLimitkbitPersec |
| TX BW Limit kbit/sec | Transmit bandwidth limit for outgoing packets as defined by the minimum of: GPO setting on client and server, local network connection, and Zero Client firmware negotiated value based on encryption limits | TXBWLimitkbitPersec |
| TX Packet Loss % | Percentage of transmitted packets lost during a sampling period. | To calculate packet loss:
?PacketSent = PacketSentsample2 – PacketSentsample1 ?TXPacketsLost = TXPacketsLostsample2 – TXPacketsLostsample1) TXPacketLoss % = ?TXPacketsLost / ?PacketSent x 100 |

| Audio RX BW kbit/sec | Bandwidth for ingoing audio packets averaged over the sampling period (in seconds). | To calculate bandwidth:
(AudioBytesReceivedsample2 – AudioBytesReceivedsample1) x 8 / 1024 / SamplePeriod |
| Audio TX BW kbit/sec | Bandwidth for outgoing audio packets averaged over the sampling period (in seconds). | To calculate bandwidth:
(AudioBytesSentsample2 – AudioBytesSentsample1) x 8 / 1024 / SamplePeriod |
| Audio TX BW Limit kbit/sec | Transmit bandwidth limit for outgoing audio packets as defined by the GPO setting. | AudioTXBWLimitkbitPersec |
