Using the Socket I/O Page

The Socket I/O page contains information about read/write activity to/from sockets.

This page displays network activity data in tables and graphs. Click the By Host, By Port, or By Host and Port icons to change the arrangement of the data in the tables.

Using the Socket I/O Page: Selections and Aspects

Use the drop-down menus at the top of the page to choose a selection and aspect if desired. Data from other pages can be saved to the selection drop-down menu by dragging an area of a chart (or selecting data from a table) and choosing Store Selection or Store Selection and Set As Focused Selection from the context menu.

The following controls provide additional behavior:

Show concurrent: Show all events concurrent to the selected aspect.
Contained: Only show events that are fully contained in the time range from the active selection aspect
Same threads: Only show events in threads related to the active selection aspect.
Time Range: Zoom to time range on relevant places on the page, or clear the time range zoom.

Table columns are labeled as follows:

Remote Address: The IP address of the remote system to which the connection was made.
Remote Port: The port on the remote system to which the connection was made.
Total I/O Time: An estimate of the total time a thread is busy with I/O. The actual total may be higher.
Count: The sum of all read and write counts.
Read Count: The total number of socket reads.
Write Count: The total number of socket writes.
Bytes Read: The total number of bytes read from sockets.
