Hello,

chudremotectrl
CHUDREMOTECTRL(1) General Commands Manual CHUDREMOTECTRL(1)NAME
chudRemoteCtrl - start or stop the collection of performance monitor data in a performance monitor remote server application.
SYNOPSIS
chudRemoteCtrl [ -m ] [ executable [args... ] ]
chudRemoteCtrl -s label
chudRemoteCtrl -e
chudRemoteCtrl -k PID
DESCRIPTION
chudRemoteCtrl is a command line tool that allows for the collection of performance data by any active performance monitor remote server
application. There are currently two CHUD Tools that can be put in remote performance monitor server mode: MONster, and Shark (as well as
their command line counterparts). Typically, chudRemoteCtrl is invoked on the command line or in a shell script, followed by the path to an
executable to be measured and its arguments. chudRemoteCtrl issues a chudStartRemotePerfMonitor message immediately after launching the
specified target program. When the launched program terminates, chudRemoteCtrl issues a chudStopRemotePerfMonitor message, and then exits.
When the '-s', '-e' or '-k PID' options are used, no program is launched.
OPTIONS -r seconds: If the 'chudStartRemotePerfMonitor' message fails to either acquire or start the remote monitoring service, then keep try-
ing to start again, until the specified number of seconds has elapsed. The same thing is true of the '-e' option. If there is a '-r
<seconds>' argument on the command line, and a failure occurs trying to stop the remote profiling program, the stop message will be
sent again until the retry time limit is reached.
-s label: Issue a chudStartRemotePerfMonitor message with the specified label and exit. A 'label' is a string of up to 32 characters.
-e Issue a chudStopRemotePerfMonitor message and exit.
-q silence some of the non-essential warning and error output.
-kPID Send a UNIX signal (SIGUSR1 to start profiling, SIGUSR2 to stop profiling) to the specified process-id. For example, if a command-
line profiling tool, is running as PID 4267, using '-k 4267' along with a '-s' will send a SIGUSR1 to the command-line profiling
tool and it will start sampling, while '-k 4267' along with a '-e' will send a SIGUSR2 to the command-line profiling tool and it
will stop sampling. A 'start' example: % chudRemoteCtrl -s session_42 -k 4267. And a 'stop' example: % chudRemoteCtrl -e -k 4267.
The command-line CHUD tool 'shark' responds to UNIX signals and toggles performance profiling. You can repeatedly send '-s <label>
-k <PID#>' to shark and it will toggle profiling start or stop. Sending '-e -k <PID#>' to shark will stop sampling (if it's run-
ning) and cause shark to EXIT.
-m Set the performance monitor mark bit in the main thread of the launched child process.
DIAGNOSTICS
chudRemoteCtrl returns a zero (0) upon success and a non-zero value on failure.
