Logging of response times

[carsten424]

Is there the possibility to log the server response time e.g. in the access log - the total response time would be an alternative?

There are many timers you can log. Here are a few of them.

+ " "

+ String.ReplaceIfEquals (Number.ToString (Timer.TimeInRuleEngine), "", "")

+ " "

+ String.ReplaceIfEquals (Number.ToString (Timer.TimeInTransaction), "", "-")

+ " "

+ String.ReplaceIfEquals (Number.ToString (Connection.RunTime), "", "-")

+ " "

+ String.ReplaceIfEquals (Number.ToString (Timer.HandleConnectToServer), "", "-")

+ " "

+ String.ReplaceIfEquals (Number.ToString (Timer.ResolveHostNameViaDNS), "", "-")

+ " "

The online help has a few more more in the appendix.

Timer. FirstReceivedFirstSentClient	Number	Processing time consumed between receiving the first byte from a client on the appliance and sending the first byte to this client within a transaction Using this property is only supported when HTTP or HTTPS connections are involved, but not for FTP connections.
Timer. FirstSentFirstReceivedServer	Number	Processing time consumed between sending the first byte from the appliance to a web server and receiving the first byte from this server within a transaction Using this property is only supported when HTTP or HTTPS connections are involved, but not for FTP connections.
Timer.HandleConnectToServer	Number	Processing time consumed for connecting to a web server within a transaction
Timer. LastReceivedLastSentClient	Number	Processing time consumed between receiving the last byte from a client on the appliance and sending the last byte to this client within a transaction Using this property is only supported when HTTP or HTTPS connections are involved, but not for FTP connections.
Timer.LastSentLastReceived FromServer	Number	Processing time consumed between sending the last byte from the appliance to a web server and receiving the last byte from this server within a transaction Using this property is only supported when HTTP or HTTPS connections are involved, but not for FTP connections.
Timer. ResolveHostNameViaDNS	Number	Processing time consumed for looking up a host name on a DNS server within a transaction Only lookups on external servers are considered. Cache lookups are disregarded.
Timer. TimeConsumedByRuleEngine	Number	Time consumed by the rule engine to process a request throughout all relevant processing cycles Processing a request through all relevant processing cycles is considered one transaction.
Timer.TimeForTransaction	Number	Time consumed by the rule engine to process a request that has been received on the appliance through all relevant processing cycles This property is only supported for HTTP or HTTPS connections, not FTP connections.

That seems great, is there a time for total time between sending the request to the server and the last byte received from the server?

[eelsasser]

Timer.TimeForTransAction is from beginning to end. I use that in my logs as the total elapsed time.

But the ones above are the ones it has.

[carsten424]

Isn't that the time including the client time, as I am looking for the server delay only.

Hi Carsten,

You can log it all if you wanted.

HandleConnect to server would represent the handshake time.

Timer. FirstSentFirstReceivedServer would represent the time between when the MWG sent the first byte to the server and when it first recieved a response back.

Otherwise any of the Timer.*Server* woud cover server timings.

Best,

Jon
