Response The ACE selects the server with the lowest response time for a requested response-time
measurement.
1. In the Response Type field, select the type of measurement to use:
–
App-Req-To-Resp—The response time from when the ACE sends an HTTP request to a
server to the time that the ACE receives a response from the server for that request.
–
Syn-To-Close—The response time from when the ACE sends a TCP SYN to a server to
the time that the ACE receives a CLOSE from the server.
–
Syn-To-Synack—The response time from when the ACE sends a TCP SYN to a server to
the time that the ACE receives a SYN-ACK from the server.
2. In the Response Samples field, enter the number of samples over which you want to average
the results of the response-time measurement. Valid entries are 1, 2, 4, 8, and 16 (integers from
1 to 16 that are also a power of 2).
3. In the Weight Connection field, check the check box to instruct the ACE to use the current
connection count in the final load calculation for a real server. When you configure this
option, the ACE includes the current connection count in the total load calculation for each
real server in a server farm. Clear the check box to reset the behavior of the ACE to the default
of excluding the current connection count from the load calculation.
Round Robin The ACE selects the next server in the list of servers based on server weight. This is the default
predictor method.
