SMB Reads and Writes Bytes Sent

The SMB Reads and Writes Bytes Sent view Layout for Charts provides a summary of byte values associated with SMB/SMB2 read, write, and open requests for file operations across a set of trace results. The summary data is presented in a Table grid visualizer component that provides an overview of the average and maximum request size in bytes for the SMB/SMB2 message/s associated with each file operation. The table contains the following columns of data:

  • FileName — specifies the name and path of files upon which an SMB operation was performed.

  • Count — specifies the number of SMB/SMB2 request messages associated with an operation.

  • Average — calculates the average size in bytes of the messages sent in an operation.

  • Max — specifies the highest message size in bytes among all messages sent in an operation.

This Layout also has a view Filter applied in the background that allows the indicated types of SMB or SMB2 requests to pass while blocking all others, in order to create focus on specific SMB/SMB2 operations.

Using the SMB Reads and Writes Bytes Sent Layout

You can create an interactive analysis context by driving the display of data into the Analysis Grid viewer. For example, you can double-click any row of data in the SMB Reads and Writes Bytes Sent Table to display the associated messages in a new instance of the Analysis Grid viewer for further assessment of Summary information and message Details.

If you redock the SMB Reads and Writes Bytes Sent view Layout so that it displays next to the Analysis Grid viewer with its default Layout in which your original data appears, you can then correlate the data in the SMB Reads and Writes Bytes Sent Table with the corresponding messages in the Analysis Grid viewer, by simply clicking a row in the Table. Each time you select a Table row, you will have immediate access to Details Tool Window data for the corresponding message that is automatically selected and highlighted in the Analysis Grid.

You might also consider displaying the Analysis Grid viewer with its File Sharing SMB/SMB2 Layout to create a grouped viewing configuration that organizes the SMB/SMB2 data by SessionId at top-level, TreeId at the first nested level, and FileName nested below that. You could also drag-and-drop the FileName label above the group message nodes in the Analysis Grid all the way to the leftmost position in the label order to reorganize the group display with FileName nodes at top-level and then use the Expand All Groups context command for each group to expose all the messages. You can then easily correlate FileName data in the SMB Reads and Writes Bytes Sent view Layout with corresponding messages in the Analysis Grid viewer by simple selection of Table rows.

The advantage of this viewing configuration is that it enables you to correlate the nested SessionId and TreeId data with the FileName row that you select in the SMB Reads and Writes Bytes Sent Table. Note that you can also sort the FileName column of the SMB Reads and Writes Bytes Sent view Layout to enable faster location of specific file names.
