Authentication fails—CIFS HTTP requests processed without a WebVPN cookie or an expired
WebVPN cookie.
Operations Aborted—Back-end operations that were aborted because the HTTP connection was
lost. Indicates that CIFS transactions are not completing successfully.
Pending Close—Number of times close is pending, waiting for Tx to unblock and finish sending
pending data.
• Socket statistics:
–
Tx Blocked—Number of times that application send was blocked by TCP congestion control.
–
Tx Unblocked—Number of times that application send resumed after being blocked due to TCP
congestion control. If transmit blocked and unblocked do not match after a sufficient period of
time, then the transaction is stalled.
–
Rx Blocked—Number of times application blocked further reception of data from TCP layer.
This indicates application buffer starvation or processing limit.
–
Rx Unblocked—Number of times application resumed further reception of data from TCP layer.
If receive blocked and unblocked do not match after a sufficient period of time, then the
transaction is stalled.
–
Premature Close—Number of times that application closed the connection before it could be
established.
–
Select Timeouts—Number of times that application timed out while waiting for a reply in a
request and reply exchange or waiting for a TCP connection to be established.
