The table consists of the following columns:
|URL_Step_Start||The URL of the page the virtual user was on when the step execution was started.|
|Date_Time||The date and time the step execution was started.|
The execution status of the step.
Possible states: pass, fail.
The unique ID of the virtual user that performed the step, including its IP address.
|Iteration count||The serial number of this iteration for the virtual user, specified in VU ID.|
|Step name||The name of the performed step in the LoadNinja script.|
|Duration (ms)||The duration of the step execution, in milliseconds.|
|Redirect time (ms)||If the tested website has initially responded with an HTTP 301 or 302 redirect, this shows the time that a virtual user spent following the redirects until getting to the final URL.|
|DNS time (ms)||The time spent performing a DNS lookup, that is, obtaining the IP address of the website from a DNS server. If this value is elevated, it indicates that a virtual user had problems with reaching the DNS server and retrieving its response.|
|Connect time (ms)||The time spent performing a TCP handshake, that is, establishing a connection to a web server after the DNS lookup. If this value is elevated, this indicates possible network and routing problems or low efficiency of the server bandwidth.|
|Time to first byte (ms)||The time spent waiting for the first byte of the response from the server. Its duration includes processing the requests, accessing the database of the server, selecting and generating the response, and depends on the server performance mostly. If this value is elevated, this indicates a possible high server load, problems with database queries, memory leaks, or other performance issues.|
