All data that is inserted into the timestamp section is generated by the Capture source. For best performance, capturing this data by a CX Passive Capture Application server provides the richest information set.
Ex and are recorded by using GMT time, as indicated
by the Z at the end of each time stamp, in the following
format:YYYY-MM-DDTHH:MM:SS:mmmmmm
The six digits at the end of the timestamp identify the microseconds in the timestamp.
| Field Name | Use | Source |
RequestTimeEx |
The time the first packet of the request was received from a client | cxImpact measured |
RequestEndTimeEx |
The time the last packet of the request was received from the client | cxImpact measured |
ResponseStartTimeEx |
The time the first packet of the response came from the web server | cxImpact measured |
ResponseTimeEx |
The time the last packet of the response came from the web server | cxImpact measured |
ResponseAckTimeEx |
The time that the ack packet acknowledged the last packet of the response came from the client | cxImpact measured |
TLapiArrivalTimeEx |
The time the ack packet was observed by Experience Analytics | cxImpact measured |
ReqTTLB |
Time from first packet of the request to the last packet of the request | cxImpact calculated |
RspTTFB |
Time from first packet of the request to the first packet of the response | cxImpact calculated |
RspTTLB |
Time from first packet of the request to the last packet of the response | cxImpact calculated |
RspTTLA |
Time from first packet of the request to the acknowledgment of the last packet of the response | cxImpact calculated |
ConnSpeed |
The average number of bytes in the response, which is divided by the RT_Total
time for all hits in the session.
|
cxImpact calculated |
ConnType |
Buckets into which the page connection speed are placed by the Session Agent in the pipeline | cxImpact calculated |
WS_Generation |
The time that it took for the web server to generate the page. It is measured from the time of the last packet of the request to the time of the last packet of the response | cxImpact calculated |
WS_Grade |
Text Description of the web server generation grade. This value is defined either on the CX Passive Capture Application server or in the TimeGrades session agent. | cxImpact calculated |
WS_GradeEx |
Number value of the web server generation grade. This value is defined either on the PCA server or in the TimeGrades session agent. | cxImpact calculated |
NT_Total |
The time that is required for the data to flow over the network. It is measured from the time of the last packet of the response to the time of receipt of the TCP/IP ACK (acknowledgment) of that packet. | cxImpact calculated |
NT_Grade |
Text Description of the network timing grade. This value is defined either on the PCA server or in the TimeGrades session agent. | cxImpact calculated |
NT_GradeEx |
Number value of the network timing grade. This value is defined either on the PCA server or in the TimeGrades session agent. | cxImpact calculated |
RT_Total |
the sum of the WS_Generation time and the NT_Total time | cxImpact calculated |
RT_Grade |
Text Description of the network round-trip grade. This value is defined either on the PCA server or in the TimeGrades session agent. | cxImpact calculated |
RT_GradeEx |
Number value of the network round-trip grade. This value is defined either on the PCA server or in the TimeGrades session agent. | cxImpact calculated |
The XX_Generation/Total fields are calculated and are measured in microseconds.
For example, WS_Generation=5000 indicates that it took 0.005 seconds to generate
the page.
The XX_Grade fields are computed fields.
One of the session agents in the cxImpact pipeline inspects the Generation time and places them into a bucket that is based on ranges of values. By default, the pipeline has buckets for:
ExcellentNormalHighNormalHighHighPlus
The XX_GradeEx fields use 0-4 to identify the same buckets. Having the Grade
expressed both as a number and as a string simplifies analysis in the Portal and third-party
tools.
The NT_Total time measures the network transit time from the web server to the
next upstream network device that terminates a TCP/IP connection, which is usually the visitor's
client browser or a proxy.
