Description
condor_config_valcan be used to quickly see what the current Condor configuration is on any given machine. Given a list of variables, con-
dor_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_valre-
quires 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 Condor dae-
mons, and they will exit. It is far better to discover such a problem on a single machine than to cause all the Condor 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 SET-
TABLE_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 SET-
TABLE_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 Condor 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 val-
ues. If the -verboseoption is supplied as well, then the specific configuration file which defined each variable, along with the line num-
ber of its definition is also printed. NOTE: The output of this argument is likely to change in a future revision of Condor. If the
-expandoption is given in addition to the -dumpoption, then variable values in the configuration files are expanded before being printed
out.
Options
-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.
Exit Status
condor_config_valwill 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_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 <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
