condor_config_valcan 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 varsargument, condor_config_valwill report what each of these variables is currently set to. If a given variable is not defined, condor_config_valwill halt on that variable, and report that it is not defined. By default, condor_config_vallooks 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. Rawoutput of condor_config_valdisplays 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 expandedone. 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 fileis not modified. condor_config_valcan be used to persistently set or unset configuration variables for a specific daemon on a given machine using a -setor -unsetedit 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 -rsetor -runsetedit option. These runtime settings will override persistent settings until the daemon is restarted. Any changes made will not take effect until condor_reconfigis invoked. In general, modifying a host's configuration with condor_config_valrequires 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 section 3.8.1on page for more details on security settings. Further, security considerations require proper settings of configuration variables SETTABLE_ATTRS_<PERMISSION-LEVEL> (see 3.5.3), ENABLE_PERSISTENT_CONFIG (see 3.5.3), and HOSTALLOW... (see 3.5.3) in order to use condor_config_valto 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_valcan help with this type of testing.
-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. -dump (view option) Display the raw value of all varslisted. If no varsare listed, then print all configuration variables and their values. The -expand, -default, and -evaluateoptions take precedence over this -dumpoption, such that the output will not be raw. -default (view option) Default values are displayed. -expand (view option) Expanded values are displayed. This is the default. -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 optionspecifies 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 optionspecifies a daemon. Modifies which variables are displayed to only those used by the specified daemon. -unused (view option) Applied only when a location optionspecifies a daemon. Modifies which variables are displayed to only those notused by the specified daemon. -config (view option) Applied only when the configuration is read from files (the default), and notwhen 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 filenameall configuration variables. Values that are the same as internal, compile-time defaults will be preceded by the comment character. If the :upgrade option 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. -mixedcase (view option) Applied only when the configuration is read from files (the default), and notwhen 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 notwhen 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 notwhen 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_masterdaemon 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. usecategory[:set name] [-expand] Display information about configuration templates (see 3.4). Specifying only a categorywill list the template_namesavailable for that category. Specifying a categoryand a template_namewill display the definition of that configuration template. Adding the -expandoption will display the expanded definition (with macro substitutions). (-expandhas no effect if a template_nameis not specified.) Note that there is no dash before useand that spaces are not allowed next to the colon character separating categoryand template_name.
condor_config_valwill exit with a status value of 0 (zero) upon success, and it will exit with the value 1 (one) upon failure.
Here is a set of examples to show a sequence of operations using condor_config_val. To request the condor_schedddaemon 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_schedddaemon 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 <22.214.171.124:52067>. 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 <126.96.36.199:52067>. 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 Getting a list of template_names for the roleconfiguration template category: % condor_config_val use role use ROLE accepts CentralManager Execute Personal Submit Getting the definition of role:personalconfiguration template: % condor_config_val use role:personal use ROLE:Personal is CONDOR_HOST=127.0.0.1 COLLECTOR_HOST=$(CONDOR_HOST):0 DAEMON_LIST=MASTER COLLECTOR NEGOTIATOR STARTD SCHEDD RunBenchmarks=0
