| ‑‑notile | Whether to initially tile windows for two or more connections. This parameter is passed as -notile to JConsole. | false |
| ‑‑pluginpath | Directories or JAR files which are searched for JConsole plugins.

Sample Output:
gfsh>start jconsole
Running JDK JConsole
The JConsole application appears and auto-connects to a JMX Manager node if one is available:
Error Messages:

start jvisualvm
Start the JDK's Java VisualVM monitoring application in a separate process.
Availability: Online or offline.
Syntax:
start jvisualvm [--J=value(,value)*]
Parameters, start jvisualvm
| Name | Description |
|---|---|
| ‑‑J | VM-option passed to the spawned CacheServer VM. For example: --J=-Dfoo.bar=true for setting foo.bar to 'true'. |
Example Commands:
start jvisualvm
Sample Output: 
start locator
Start a locator.
The command creates a subdirectory and log file named after the locator. If the locator detects that no other JMX Manager exists, then the locator will automatically start an embedded JMX Manager and connect the current gfsh session to the JMX Manager.
Note: You must have JAVA_HOME set before starting gfsh to use this command.
In addition, if gfsh is not already connected to a JMX Manager, the gfsh console will automatically connect to the new embedded JMX Manager started by the new locator.
Note: When both --max-heap and --initial-heap are specified during locator startup, additional GC parameters are specified internally by Geode's Resource Manager. If you do not want the additional default GC properties set by the Resource Manager, then use the-Xms and -Xmx JVM options. See Controlling Heap Use with the Resource Manager for more information.
Note: The additional GC parameters introduced by the --max-heap option are not compatible with the usage of G1 garbage collector.
Availability: Online or offline.

|
| ‑‑hostname-for-clients | Sets the IP address or host name that a locator will provide to clients. Clients use the address to connect to a server. Set this value when clients use a different address to connect with the server than the bind-address, as those clients might with servers in a private cloud or multi-homed environment. Not specifying this option or setting this option to the empty string ("") causes the bind-address to be given to clients. | |
| ‑‑max-connections | Sets the maximum number of client connections allowed. When the maximum is reached the cache server will stop accepting connections. | |
| ‑‑message-time-to-live | Sets the time (in seconds ) after which a message in the client queue will expire. | |
| ‑‑max-message-count | Sets maximum number of messages that can be enqueued in a client-queue. | |

| ‑‑off-heap-memory-size | The integer quantity of off-heap memory to be used for storing region values. Specified in Gigabytes with a "g" suffix, or Megabytes with an "m" suffix. For example, allocate a 2 Gigabyte off-heap space with --off-heap-memory-size=2g. The default value of 0 does not use any off-heap memory. | 0 |
| ‑‑start-rest-api | When true, starts the REST API service. | false |
| ‑‑redirect-output | When true, redirect standard output and standard error to the server log file. If specified without a value, the value is set to true. | false |
| ‑‑http-service-port | Specifies the HTTP service port. | 7070 |
| ‑‑http-service-bind-address | Specifies the IP address to which the HTTP service will be bound. | the local host machine's address |
| ‑‑username ‑‑user | The user name of the credential to use in authenticating to the cluster. When specified, if the --password option is not also specified, then gfsh will prompt for the password. | |
