Chart and Table Descriptions
SMB: Request Optimization
The SMB Request Optimization chart displays the percentage of SMB command responses that use the
following optimizations: read ahead, metadata, write, and other.
SMB: Response Time Savings
The SMB Response Time Savings chart displays a graph of the round-trip response time saved by the
SMB accelerator due to the following optimizations, which are displayed in different colors: read ahead,
metadata, Microsoft Office, async write, named pipe, and other. The time units (milliseconds, seconds,
or minutes) at the left side depend on the range.
SMB: Versions Detected
The SMB Versions Detected pie chart displays the number of SMB messages detected for each SMB
version: SMB v1.0 optimized, SMB v1.0 unoptimized, SMB v1.0 signed, SMB v2.0 optimized, SMB
v2.0 unoptimized, SMB v2.0 signed, SMB v2.1 optimized, SMB v2.1 unoptimized, and SMB v2.1
signed.
ICA Acceleration Charts
This section describes these charts:
• ICA: Client Versions, page 1-24
• ICA: Connection Details, page 1-24
• ICA: Effective WAN Capacity, page 1-24
• ICA: Unaccelerated Reasons, page 1-25
ICA: Client Versions
The ICA Client Versions pie chart displays the number of ICA messages detected for each ICA version:
online plugin 11.0, online plugin 11.2, online plugin 12.0, online plugin 12.1, Citrix Receiver 13.0, and
other.
ICA: Connection Details
The ICA Connection Details chart displays the ICA session connection statistics, showing the average
number of active ICA connections per device (at the device level for the last hour it shows the exact
number). Click the Details tab to display the newly handled ICA connections, optimized connections,
handed-off connections, and dropped connections.
ICA: Effective WAN Capacity
The ICA Effective WAN Capacity chart displays the effective bandwidth capacity of the WAN link as a
result of ICA acceleration, as a multiplier of its base capacity. The capacity data for all traffic and ICA
traffic is shown.
Note If the chart has no data, monitoring may be disabled for the application definition that includes this type
of traffic. Check that monitoring is enabled for the Citrix application.
