The Socket Read tab contains information about the socket read operations that occurred during the time of recording.
For information about using the range navigator, see Using the Range Navigator.
The socket read events can be presented either by the hosts read from, by threads that initiated the read event, or both. Switch between modes using the By Host, By Thread, and By Event subtabs. Each subtab contains a similar set of panels, providing a list of socket read events and details for the selected events.
The top panel in each subtab of the Socket Read tab (Socket Reads by Host, Socket Reads by Thread, and All Socket Reads) contains a table with the list of socket read events. Depending on the subtab, this table can contain the following columns:
Thread: The thread that initiated the read operation.
Remote Address: The address of the socket from which data is read.
Remote Host: The host where the socket was opened.
Number of Ports: The number of ports opened by the socket.
Duration: The duration of the read operations for the socket or thread.
Bytes Read: The total size of data read from the socket.
Number of Reads: The number of times that data was read from the socket.
To filter the table entries, select the column on which you want to filter and then specify the filtering string. You can use wildcards in the filtering string and specify a regular expression by prepending it with regexp:
. If the table contains numeric values, you can specify a logical expression using the comparison operators (<
, <=
, >
, >=
), the AND operator (&&
), and the OR operator (||
).
For information about working with tables, see Working with Tables.
The Socket Reads over Time panel contains a graph that shows the amount of data read over time. Depending on the opened subtab of the Socket Read tab, this graph shows read data size for the selected socket, selected thread, or selected event.
The Socket Read Trace Tree contains a table with the stack trace for the selected socket, thread, or event. It also shows the number of read operations for each method on the stack.
