condor_procd Track - and manage process families
condor_procd -h condor_procd-A address-file[options]
condor_procdtracks and manages process families on behalf of the HTCondor daemons. It may track families of PIDs via relationships such as: direct parent/child, environment variables, UID, and supplementary group IDs. Management of the PID families include * registering new families or new members of existing families * getting usage information * signaling families for operations such as suspension, continuing, or killing the family * getting a snapshot of the tree of families In a regular HTCondor installation, this program is not intended to be used or executed by any human. The required argument, -A address-file, is the path and file name of the address file which is the named pipe that clients must use to speak with the condor_procd.
-h Print out usage information and exit. -D Wait for the debugger. Initially sleep 30 seconds before beginning normal function. -C principal The principalis the UID of the owner of the named pipe that clients must use to speak to the condor_procd . -L log-file A file the condor_procd will use to write logging information. -E When specified, another tool such as the procd_ctltool must allocate the GID associated with a process. When this option is notspecified, the condor_procd will allocate the GID itself. -P PID If not specified, the condor_procd will use the condor_procd 's parent, which may not be PID 1 on Unix, as the parent of the condor_procd and the root of the tracking family. When not specified, if the condor_procd 's parent PID dies, the condor_procd exits. When specified, the condor_procd will track this PIDfamily in question and not also exit if the PID exits. -S seconds The maximum number of seconds the condor_procd will wait between taking snapshots of the tree of families. Different clients to the condor_procd can specify different snapshot times. The quickest snapshot time is the one performed by the condor_procd . When this option is not specified, a default value of 60 seconds is used. -G min-gid max-gid If the -Eoption is notspecified, then track process families using a self-allocated, free GID out of the inclusive range specified by min-gidand max-gid. This means that if a new process shows up using a previously known GID, the new process will automatically associate into the process family assigned that GID. If the -Eoption isspecified, then instead of self-allocating the GID, the procd_ctltool must be used to associate the GID with the PID root of the family. The associated GID must still be in the range specified. This is a Linux-only feature. -K windows-softkill-binary This is the path and executable name of the condor_softkill.exebinary. It is used to send softkill signals to process families. This is a Windows-only feature. -I glexec-kill-path glexec-path Specifies, with glexec-kill-path, the path and executable name of a binary used to send a signal to a PID. The glexecbinary, specified by glexec-path, executes the program specified with glexec-kill-pathunder the right privileges to send the signal.
This program may be used in a stand alone mode, independent of HTCondor, to track process families. The programs procd_ctland gidd_allocare used with the condor_procdin stand alone mode to interact with the daemon and to inquire about certain state of running processes on the machine, respectively.
condor_procdwill exit with a status value of 0 (zero) upon success, and it will exit with the value 1 (one) upon failure.
