    Replace the ``<option>`` with one of the following options
    supported by this command:
 
-   :option integer journalCommitInterval: Specify an integer between 1
-                                          and 500 specifying the
-                                          number of milliseconds (ms)
-                                          between journal commits.
-
-   :option integer logLevel: Specify an integer between ``0`` and
-                             ``5`` signifying the verbosity of the
-                             logging, where larger is more verbose.
-
-   :option boolean notablescan: If ``true``, queries that do not
-                                using an index will fail.
-
-   :option boolean traceExceptions: If ``true``, :program:`mongod` will
-                                    log full stack traces on assertions

-                                    available in version 2.1 and later.

-   :option boolean quiet: Enables a quiet logging mode when
-                          ``true``. Use ``false`` to disable. Quiet

+   :option integer journalCommitInterval: 
+   
+           Specify an integer between ``1`` and ``500`` signifying the number
+           of milliseconds (ms) between journal commits.
+
+           Consider the following example which sets the
+           :option:`journalCommitInterval` to ``200`` ms:
+                                       
+           .. code-block:: javascript
+   
+              use admin
+              db.runCommand( { setParameter: 1, journalCommitInterval: 200 } )
+                              
+   :option integer logLevel: 
+   
+           Specify an integer between ``0`` and ``5`` signifying the
+           verbosity of the logging, where ``5`` is the most verbose.
+
+           Consider the following example which sets the
+           :option:`logLevel` to ``2``:
+                                       
+           .. code-block:: javascript
+

+                                
+   :option boolean notablescan: 
+   
+           Specify whether queries must use indexes. If ``true``,
+           queries that perform a table scan instead of using an index
+           will fail.
+
+           Consider the following example which sets the
+           :option:`notablescan` to true:
+                                       
+           .. code-block:: javascript
+

+   
+           .. versionadded:: 2.1
+           
+           Specify whether to log full stack traces on assertions or
+           errors. If ``true``, :program:`mongod` will log full stack
+           traces on assertions or errors.
+
+           Consider the following example which sets the
+           :option:`traceExceptions` to true:

+   
+              use admin
+              db.runCommand( { setParameter: 1, traceExceptions: true } )
+
+   :option boolean quiet: 
+   
+           Specify whether to go into a quiet logging mode. If
+           ``true``, :program:`mongod` will go into a quiet logging
+           mode which will not log the following events/activities: 
+           
+              - connection events;
+              - the :dbcommand:`drop` command, the
+                :dbcommand:`dropIndexes` command, the
+                :dbcommand:`diagLogging` command, the
+                :dbcommand:`validate` command, and the
+                :dbcommand:`clean` command; and
+              - replication synchronization activities.
+
+           Consider the following example which sets the
+           :option:`quiet` to true:
+
+           .. code-block:: javascript
+   
+              use admin
+              db.runCommand( { setParameter: 1, quiet: true } )
+
+   :option integer syncdelay: 
+   
+           Specify the interval, in seconds, between :term:`fsyncs
+           <fsync>` (i.e., flushes of memory to disk). By default,
+           :program:`mongod` will flush memory to disk every 60
+           seconds. Do not change this value unless you see a
+           background flush average greater than 60 seconds.
+
+           Consider the following example which sets the
+           :option:`syncdelay` to 60:
+
+           .. code-block:: javascript
+   
+              use admin
+              db.runCommand( { setParameter: 1, syncdelay: 60 } )
