--- name: "condor_config_val" section: "1" platform: "linux" package: "condor" version: "23.9.6+dfsg-2.1+b10" release: "Debian 13 (Trixie)" platforms: ["linux"] url: "https://new.carta.tech/condor_config_val" --- # condor\_config\_val(1) HTCondor Manual Query or set a given HTCondor configuration variable ## NAME condor\_config\_val - HTCondor Manual Query or set a given HTCondor configuration variable ## SYNOPSIS **condor\_config\_val** *\* **condor\_config\_val** \[**\** \] *\* **condor\_config\_val** \[**\** \] \[**\** \] *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\_\*, *ENABLE\_PERSISTENT\_CONFIG*, and *ALLOW\_CONFIG* 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\[:\\]** (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(\)**. 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** *\* (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** *\* (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** *\* (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** *\* (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 ``` Getting a list of template\_names for the **role** configuration template category: ``` $ condor_config_val use role use ROLE accepts CentralManager Execute Personal Submit ``` Getting the definition of **role:personal** configuration 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 ``` ## AUTHOR HTCondor Team ## COPYRIGHT 1990-2024, Center for High Throughput Computing, Computer Sciences Department, University of Wisconsin-Madison, Madison, WI, US.
