procd_ctl (1) - Linux Manuals

Command to display procd_ctl manual in Linux: $ man 1 procd_ctl

Name

procd_ctl command line interface to the condor_procd

Synopsis

procd_ctl -h

procd_ctl -A address-file [ command ]

Description

This is a programmatic interface to the condor_procd daemon. It may be used to cause the condor_procd to do anything that the condor_procd is capable of doing, such as tracking and managing process families.

This is a program only available for the Linux ports of HTCondor.

The -h option prints out usage information and exits. The address-file specification within the -A argument specifies the path and file name of the address file which the named pipe clients must use to speak with the condor_procd .

One command is given to the condor_procd . The choices for the command are defined by the Options.

Options

TRACK_BY_ASSOCIATED_GID GID [ PID ]

: Use the specified GID to track the specified family rooted at PID . If the optional PID is not specified, then the PID used is the one given or assumed by condor_procd .

GET_USAGE [ PID ]

: Get the total usage information about the PID family at PID . If the optional PID is not specified, then the PID used is the one given or assumed by condor_procd .

DUMP [ PID ]

: Print out information about both the root PID being watched and the tree of processes under this root PID . If the optional PID is not specified, then the PID used is the one given or assumed by condor_procd .

LIST [ PID ]

: With no PID given, print out information about all the watched processes. If the optional PID is specified, print out information about the process specified by PID and all its child processes.

SIGNAL_PROCESS signal [ PID ]

: Send the signal to the process specified by PID . If the optional PID is not specified, then the PID used is the one given or assumed by condor_procd .

SUSPEND_FAMILY PID

: Suspend the process family rooted at PID .

CONTINUE_FAMILY PID

: Continue execution of the process family rooted at PID .

KILL_FAMILY PID

: Kill the process family rooted at PID .

UNREGISTER_FAMILY PID

: Stop tracking the process family rooted at PID .

SNAPSHOT

: Perform a snapshot of the tracked family tree.

QUIT

: Disconnect from the condor_procd and exit.

General Remarks

This program may be used in a standalone mode, independent of HTCondor, to track process families. The programs procd_ctl and gidd_alloc are used with the condor_procd in standalone mode to interact with the daemon and inquire about certain state of running processes on the machine, respectively.

Exit Status

procd_ctl will exit with a status value of 0 (zero) upon success, and it will exit with the value 1 (one) upon failure.
