       This  command  receives  tracing  data  from  the network and saves it to files.  Data will be sent using
       uftrace-record with --host option.

       The uftrace recv command should be run before sending data by record command.

              # HOST
              $ uftrace recv -d recv_data --port 1234

       Above command starts a server with port by given (default 8090) to receive data from remote client.

              # CLIENT
              $ uftrace record -d example_data --host localhost --port 1234 example

       Above  command  sends the trace data to a remote server that pointed by given --host option (localhost in
       this case) after running the example program.  And as you see, you can choose save directory by using  -d
       option (sending data will save to example_data in this case).

              # HOST : Check received data
              $ uftrace replay -d recv_data/example_data
              # DURATION    TID     FUNCTION
                          [17308] | main() {
                          [17308] |   a() {
                          [17308] |     b() {
                          [17308] |       c() {
                 1.058 us [17308] |         getpid();
                 4.356 us [17308] |       } /* c */
                 4.664 us [17308] |     } /* b */
                 4.845 us [17308] |   } /* a */
                 5.076 us [17308] | } /* main */

       You  can  find  saved  trace  data of example from recv_data’s subdirectory example_data.  Obviously, you
       should check at HOST.
