condor_procd(1) General Commands Manual condor_procd(1)
Name
condor_procd Track - and manage process families
Synopsis
condor_procd -h
condor_procd-A address-file[options]
Description
condor_procdtracks and manages process families on behalf of the Condor 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 Condor 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.
Options
-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 notspeci-
fied, 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 con-
dor_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 con-
dor_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.
General Remarks
This program may be used in a stand alone mode, independent of Condor, 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.
Exit Status
condor_procdwill exit with a status value of 0 (zero) upon success, and it will exit with the value 1 (one) upon failure.
