statistics you want to graph for the selected user.
Table 12 describes the types of statistics you can choose.
Table 12 Protocol Statistics
Value Meaning Trends to Look For...
GRE (Generic
Routing
Encapsulation) Flow Pkts The number of GRE packets
dropped by the Aurorean
Network Gateway due to flow
control and full receive
buffers. This value usually indicates
congestion at the Aurorean
Network Gateway caused by a
large number of users logged in
and/or a high volume of data
being transferred. Sudden spikes
in this graph occur when the
Aurorean Network Gateway is
unable to keep pace with
incoming tunnel packets.
Pkts Lost The number of GRE packets
lost by the Aurorean Network
Gateway. This value indicates checksum
failures, corrupted packet
headers, or flow control problems
(the Flow Pkts count is included in
this value). Sudden spikes in this
graph occur when the Aurorean
Network Gateway is unable to
keep pace with incoming tunnel
packets.
Acks Recvd The number of GRE
acknowledgment packets
received by the Aurorean
Network Gateway. These values result from
overhead traffic between the
Aurorean Network Gateway and
the remote client (packets which
did not contain actual user data).
Sudden spikes usually occur
when a connection begins as the
Aurorean Network Gateway and
remote client negotiate
authentication, encryption, and
compression options to use on
the connection.
Acks Sent The number of GRE
acknowledgment packets sent
to the remote client.
