Socket counters

These counters provide information about connections started, send and receive actions completed, and connection times. Some counters produce an aggregate value, where the values for several send and receive actions are represented in one value; others produce values for each action.

Aggregate counters use the values for all the connections in a test to produce a single value for a report. This value is calculated from all values that satisfy the counter. When you drag an aggregate counter onto a report, one value is displayed. Folders containing aggregate counters have a clock superimposed on the folder icon:

. The following tables that list aggregate counters have this icon in their title.

Individual counters produce values for each connection that satisfies the counter, rather than a single aggregate value. Folders containing individual counters have an asterisk superimposed on the folder icon:

. The following tables that list individual counters have this icon in their title.

Some counters pertain to intervals in the run. You set the Statistics sample interval value in the schedule as a schedule property.


Bytes Received counters

The counters in this section provide information about the number of bytes that were received.

Socket Counters>

Bytes Received

Counter name Description
Count [for Interval] Number of bytes received for a specific connection during the most recent sample interval
Count [for Run] Number of bytes received for a specific connection for the entire run


Bytes Sent counters

The counters in this section provide information about the number of bytes that were sent.

Socket Counters>

Bytes Sent

Counter name Description
Count [for Interval] Number of bytes sent for a specific connection within the most recent sample interval
Count [for Run] Number of bytes sent for a specific connection for the entire run


Connect Attempts counters

The counters in this section provide information about the number of attempts to establish a connection with the server.

Socket Counters>

Connect Attempts

Counter name Description
Count [for Interval] Number of attempts to establish a connection within the most recent sample interval
Count [for Run] Number of attempts to establish a connection for the entire run


Connect Times counters

The counters in this section provide information about the connection response time. This is the time, in milliseconds, that elapses from the point that the test client attempts to establish a connection with the server and the moment the connection is established.

Socket Counters>

Connect Times

Counter name Description
Average [for Interval] Average connection time for a specific connection during the most recent sample interval
Average [for Run] Average connection time for a specific connection for the entire run
Maximum [for Interval] Maximum connection time for a specific connection during the most recent sample interval
Maximum [for Run] Maximum connection time for a specific connection for the entire run
Minimum [for Interval] Minimum connection time for a specific connection during the most recent sample interval
Minimum [for Run] Minimum connection time for a specific connection for the entire run
Standard Deviation [for Interval] Standard deviation of connection times for a specific connection during the most recent sample interval
Standard Deviation [for Run] Standard deviation of connection times for a specific connection for the entire run

Maximum [ms] [for Interval] Maximum connection time for all connections within the most recent sample interval
Maximum [ms] [for Run] Maximum connection time for all connections for the entire run
Minimum [ms] [for Interval] Minimum connection time for a all connections within the most recent sample interval
Minimum [ms] [for Run] Minimum connection time for a all connections for the entire run
