Calculating Bandwidth for Transmitted Network Data
To calculate the bandwidth in kilobits per second for transmitted data over the time interval from time t1 to
time t2, use the following formula.
(BytesSent[t2]-BytesSent[t1]) * 8 / (1024 * (t2-t1))
Do not use TXBWkbitPersec for the calculation.
Calculating Packet Loss for Received Network Data
To calculate the packet loss in percentage for received data over the time interval from time t1 to time t2,
use the following formula.
PacketsReceived during interval = (PacketsReceived[t2]-PacketsReceived[t1])
RXPacketsLost during interval = (RXPacketsLost[t2]-RXPacketsLost[t1])
RXPacketsLost % = RXPacketsLost during interval /
(RXPacketsLost during interval + PacketsReceived during interval) * 100
Do not use RXPacketLostPercent or RXPacketLostPercent_Base for the calculation.
Calculating Packet Loss for Transmitted Network Data
To calculate the packet loss in percentage for transmitted data over the time interval from time t1 to time t2,
use the following formula.
PacketsSent during interval = (PacketsSent[t2]-PacketsSent[t1])
TXPacketsLost during interval = (TXPacketsLost[t2]-TXPacketsLost[t1])
TXPacketsLost % = TXPacketsLost during interval /
(TXPacketsLost during interval + PacketsSent during interval) * 100
Do not use TXPacketLostPercent or TXPacketLostPercent_Base for the calculation.
Use this formula to prevent the packet loss percent from becoming greater than 100 percent. This calculation
is required because PacketsLost and PacketsSent are asynchronous.
PCoIP USB Statistics
The WMI class name for PCoIP USB statistics is
Win32_PerfRawData_TeradiciPerf_PCoIPSessionUSBStatistics.
Table 65. PCoIP USB Statistics
WMI Property Name Description
USBBytesReceived
Total number of bytes of USB data that have been received since the PCoIP
session started.
USBBytesSent
Total number of bytes of USB data that have been transmitted since the
PCoIP session started.
USBRXBWkbitPersec
Bandwidth for incoming USB packets averaged over the sampling period, in
seconds.
USBTXBWkbitPersec
Bandwidth for outgoing USB packets averaged over the sampling period, in
seconds.
