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.
