NAME

       uftrace-recv - Receive tracing data from socket and save it to files

SYNOPSIS

       uftrace recv [options]

DESCRIPTION

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

OPTIONS

       -d DATA, --data=DATA
              Specify directory name to save received data.

       --port=PORT
              Use given port instead of the default (8090).

       --run-cmd=COMMAND
              Run given (shell) command as soon as receive data.  For example, one can run  uftrace  replay  for
              received data.

EXAMPLE

       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.
