NAME
condor_config_val - HTCondor Manual
Query or set a given HTCondor configuration variable
SYNOPSIS
condor_config_val <help option>
condor_config_val [<location options> ] <edit option>
condor_config_val [<location options> ] [<view options> ] vars
condor_config_val use category [:template_name ] [-expand ]
DESCRIPTION
condor_config_val can be used to quickly see what the current HTCondor configuration is on any given
machine. Given a space separated set of configuration variables with the vars argument, condor_config_val
will report what each of these variables is currently set to. If a given variable is not defined,
condor_config_val will halt on that variable, and report that it is not defined. By default,
condor_config_val looks in the local machine's configuration files in order to evaluate the variables.
Variables and values may instead be queried from a daemon specified using a location option.
Raw output of condor_config_val displays the string used to define the configuration variable. This is
what is on the right hand side of the equals sign (=) in a configuration file for a variable. The default
output is an expanded one. Expanded output recursively replaces any macros within the raw definition of a
variable with the macro's raw definition.
Each daemon remembers settings made by a successful invocation of condor_config_val. The configuration
file is not modified.
condor_config_val can be used to persistently set or unset configuration variables for a specific daemon
on a given machine using a -set or -unset edit option. Persistent settings remain when the daemon is
restarted. Configuration variables for a specific daemon on a given machine may be set or unset for the
time period that the daemon continues to run using a -rset or -runset edit option. These runtime settings
will override persistent settings until the daemon is restarted. Any changes made will not take effect
until condor_reconfig is invoked.
In general, modifying a host's configuration with condor_config_val requires the CONFIG access level,
which is disabled on all hosts by default. Administrators have more fine-grained control over which
access levels can modify which settings. See the Security section for more details on security settings.
Further, security considerations require proper settings of configuration variables
SETTABLE_ATTRS_<PERMISSION-LEVEL>, ENABLE_PERSISTENT_CONFIG, and ALLOW in order to use condor_config_val
to change any configuration variable.
It is generally wise to test a new configuration on a single machine to ensure that no syntax or other
errors in the configuration have been made before the reconfiguration of many machines. Having bad syntax
or invalid configuration settings is a fatal error for HTCondor daemons, and they will exit. It is far
better to discover such a problem on a single machine than to cause all the HTCondor daemons in the pool
to exit. condor_config_val can help with this type of testing.
OPTIONS
-help (help option) Print usage information and exit.
-version
(help option) Print the HTCondor version information and exit.
-set "var = value"
(edit option) Sets one or more persistent configuration file variables. The new value remains
if the daemon is restarted. One or more variables can be set; the syntax requires double quote
marks to identify the pairing of variable name to value, and to permit spaces.
-unset var
(edit option) Each of the persistent configuration variables listed reverts to its previous
value.
-rset "var = value"
(edit option) Sets one or more configuration file variables. The new value remains as long as
the daemon continues running. One or more variables can be set; the syntax requires double
quote marks to identify the pairing of variable name to value, and to permit spaces.
-runset var
(edit option) Each of the configuration variables listed reverts to its previous value as long
as the daemon continues running.
-summary[:detected]
(view option) For all configuration variables that differ from default value, print out the
name and value. The values are grouped by the file that last set the variable, and in the order
that they were set in that file. If the detected option is added, then variables such as
$(OPSYSANDVER) that are detected at runtime are included in the ouput.
-dump (view option) For all configuration variables that match vars, display the variables and their
values. If no vars are listed, then display all configuration variables and their values. The
values will be raw unless -expand, -default, or -evaluate are used.
-default
(view option) Default values are displayed.
-expand
(view option) Expanded values are displayed. This is the default unless -dump is used.
-raw (view option) Raw values are displayed.
-verbose
(view option) Display configuration file name and line number where the variable is set, along
with the raw, expanded, and default values of the variable.
-debug[:<opts>]
(view option) Send output to stderr, overriding a set value of TOOL_DEBUG.
-evaluate
(view option) Applied only when a location option specifies a daemon. The value of the
requested parameter will be evaluated with respect to the ClassAd of that daemon.
-used (view option) Applied only when a location option specifies a daemon. Modifies which variables
are displayed to only those used by the specified daemon.
-unused
(view option) Applied only when a location option specifies a daemon. Modifies which variables
are displayed to only those not used by the specified daemon.
-config
(view option) Applied only when the configuration is read from files (the default), and not
when applied to a specific daemon. Display the current configuration file that set the
variable.
-writeconfig[:upgrade] filename
(view option) For the configuration read from files (the default), write to file filename all
configuration variables. Values that are the same as internal, compile-time defaults will be
preceded by the comment character. If the :upgrade o ption is specified, then values that are
the same as the internal, compile-time defaults are omitted. Variables are in the same order as
the they were read from the original configuration files.
-macro[:path]
(view option) Macro expand the text in vars as the configuration language would. You can use
expansion functions such as $F(<var>). If the :path o ption is specified, treat the result as a
path and return the canonical form.
-mixedcase
(view option) Applied only when the configuration is read from files (the default), and not
when applied to a specific daemon. Print variable names with the same letter case used in the
variable's definition.
-local-name <name>
(view option) Applied only when the configuration is read from files (the default), and not
when applied to a specific daemon. Inspect the values of attributes that use local names, which
is useful to distinguish which daemon when there is more than one of the particular daemon
running.
-subsystem <daemon>
(view option) Applied only when the configuration is read from files (the default), and not
when applied to a specific daemon. Specifies the subsystem or daemon name to query, with a
default value of the TOOL subsystem.
-address <ip:port>
(location option) Connect to the given IP address and port number.
-pool centralmanagerhostname[:portnumber]
(location option) Use the given central manager and an optional port number to find daemons.
-name <machine_name>
(location option) Query the specified machine's condor_master daemon for its configuration.
Does not function together with any of the options: -dump, -config, or -verbose.
-master | -schedd | -startd | -collector | -negotiator
(location option) The specific daemon to query.
use category [:set name ] [-expand ]
Display information about configuration templates (see
admin-manual/introduction-to-configuration:configuration templates). Specifying only a
category will list the template_names available for that category. Specifying a category and a
template_name will display the definition of that configuration template. Adding the -expand
option will display the expanded definition (with macro substitutions). (-expand has no effect
if a template_name is not specified.) Note that there is no dash before use and that spaces are
not allowed next to the colon character separating category and template_name.
EXIT STATUS
condor_config_val will exit with a status value of 0 (zero) upon success, and it will exit with the value
1 (one) upon failure.
EXAMPLES
Here is a set of examples to show a sequence of operations using condor_config_val. To request the
condor_schedd daemon on host perdita to display the value of the MAX_JOBS_RUNNING configuration variable:
$ condor_config_val -name perdita -schedd MAX_JOBS_RUNNING
500
To request the condor_schedd daemon on host perdita to set the value of the MAX_JOBS_RUNNING
configuration variable to the value 10.
$ condor_config_val -name perdita -schedd -set "MAX_JOBS_RUNNING = 10"
Successfully set configuration "MAX_JOBS_RUNNING = 10" on
schedd perdita.cs.wisc.edu <128.105.73.32:52067>.
A command that will implement the change just set in the previous example.
$ condor_reconfig -schedd perdita
Sent "Reconfig" command to schedd perdita.cs.wisc.edu
A re-check of the configuration variable reflects the change implemented:
$ condor_config_val -name perdita -schedd MAX_JOBS_RUNNING
10
To set the configuration variable MAX_JOBS_RUNNING back to what it was before the command to set it to
10:
$ condor_config_val -name perdita -schedd -unset MAX_JOBS_RUNNING
Successfully unset configuration "MAX_JOBS_RUNNING" on
schedd perdita.cs.wisc.edu <128.105.73.32:52067>.
A command that will implement the change just set in the previous example.
$ condor_reconfig -schedd perdita
Sent "Reconfig" command to schedd perdita.cs.wisc.edu
A re-check of the configuration variable reflects that variable has gone back to is value before initial
set of the variable:
$ condor_config_val -name perdita -schedd MAX_JOBS_RUNNING
500
