condor_config_val Query - or set a given HTCondor configuration variable
condor_config_val [options] [-config] [-verbose] variable[variable ... ] condor_config_val[options] -set string[string ... ] condor_config_val[options] -rset string[string ... ] condor_config_val[options] -unset variable[variable ... ] condor_config_val[options] -runset variable[variable ... ] condor_config_val[options] -tilde condor_config_val[options] -owner condor_config_val[options] -config condor_config_val-dump[-expand] [-verbose]
condor_config_valcan be used to quickly see what the current HTCondor configuration is on any given machine. Given a list of variables, 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. condor_config_valcan also be used to quickly set configuration variables for a specific daemon on a given machine. Each daemon remembers settings made by condor_config_val. The configuration file is not modified by this command. Persistent settings remain when the daemon is restarted. Runtime settings are lost when the daemon is restarted. 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 3.6.1on page for more details on security settings. The -verboseoption displays the configuration file name and line number where a configuration variable is defined. Any changes made by condor_config_valwill not take effect until condor_reconfigis invoked. 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. The -setoption sets one or more persistent configuration file entries. The stringmust be a single argument, so enclose it in double quote marks. A string must be of the form "variable = value" . Use of the -setoption implies the use of configuration variables SETTABLE_ATTRS... (see 3.3.5), ENABLE_PERSISTENT_CONFIG (see 3.3.5), and HOSTALLOW... (see 3.3.5). The -rsetoption sets one or more runtime configuration file entries. The stringmust be a single argument, so enclose it in double quote marks. A string must be of the form "variable = value" . Use of the -rsetoption implies the use of configuration variables SETTABLE_ATTRS... (see 3.3.5), ENABLE_RUNTIME_CONFIG (see 3.3.5), and HOSTALLOW... (see 3.3.5). The -unsetoption changes one or more persistent configuration file entries to their previous value. The -runsetoption changes one or more runtime configuration file entries to their previous value. The -tildeoption displays the path to the HTCondor home directory. The -owneroption displays the owner of the condor_config_valprocess. The -configoption displays the current configuration files in use. The -dumpoption displays a list of all of the defined macros in the configuration files found by condor_config_val, along with their values. If the -verboseoption is supplied as well, then the specific configuration file which defined each variable, along with the line number of its definition is also printed. NOTE: The output of this argument is likely to change in a future revision of HTCondor. If the -expandoption is given in addition to the -dumpoption, then variable values in the configuration files are expanded before being printed out.
-name machine_name Query the specified machine's condor_masterdaemon for its configuration. Does not function together with any of the options: -dump, -config, or -verbose. -pool centralmanagerhostname[:portnumber] Use the given central manager and an optional port number to find daemons. -address <ip:port> Connect to the given IP address and port number. -master | -schedd | -startd | -collector | -negotiator The specific daemon to query. -local-name Inspect the values of attributes that use local names. -evaluate The value of the requested parameter will be evaluated with respect to the ClassAd of that daemon.
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 <184.108.40.206:52067>. 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 <220.127.116.11:52067>. 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
