Chart and Table Descriptions
MAPI: Acceleration Bypass Reason
The MAPI Acceleration Bypass Reason pie chart displays the reasons that encrypted MAPI traffic is not
accelerated: acceleration disabled, secret retriever disabled, unsupported cipher, unsupported
authentication mechanism, misconfigured domain identity, failure in secret retrieval, general security
failure, insufficient system resources, and recovery mode connections.
Click the Non-Encrypted tab to display the bypass reasons for unencrypted MAPI traffic: reservation
failure (non-overload), reservation failure (overload), signed MAPI request, malformed RPC packet,
handover request from peer, unsupported server version, user in denied list, unsupported client version,
secured connections (encrypted), unsupported DCERPC protocol version, association group not tracked,
and other.
MAPI: Average Response Time Saved
The MAPI Average Response Time Saved chart displays a graph of the estimated percentage of response
time saved by the MAPI accelerator. The time units (microseconds, milliseconds, seconds, or minutes)
at the left side depend upon the range.
MAPI: Connection Details
The MAPI Connection Details chart displays the MAPI session connection statistics, showing the
average number of active MAPI 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 MAPI connections, optimized
connections, handed-off connections, and dropped connections. Click the Optimized Encrypted vs
Non-Encrypted tab to display the new encrypted and unencrypted MAPI connections.
MAPI: Effective WAN Capacity
The MAPI Effective WAN Capacity chart displays the effective bandwidth capacity of the WAN link as
a result of MAPI acceleration, as a multiplier of its base capacity. The capacity data for all traffic and
MAPI 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 Email-and-Messaging application.
MAPI: Request Optimization
The MAPI Request Optimization chart displays the percentage of local and remote MAPI command
responses. A local response is a response that is sent to the client from the local WAE. A remote response
comes from the remote server. Click the Encrypted vs Non-Encrypted tab to display the percentage of
local and remote responses for encrypted and unencrypted MAPI connections.
MAPI: Response Time Optimization
The MAPI Response Time Optimization chart compares the average time used for local and remote
MAPI responses. The time units (microseconds, milliseconds, seconds, or minutes) at the left side
depend upon the range. Click the Encrypted vs Non-Encrypted tab to display the average time used for
local and remote responses for encrypted and unencrypted MAPI connections.
