Verify Server Status

Use themps-statuscommand to verify the status of an on-premisesMATLAB^®Production Server™instance. You can usemps-statusafter issuing commands such asmps-start,国会议员, andmps-restartto check if the server has started or stopped. The output ofmps-statuscontains information about the status of theMATLAB Production Serverinstance and also information about the license server that theMATLAB Production Serverinstance uses.

Procedure

Open a system command prompt.
Enter the following command:
```
mps-status [-Cpath/]server_name
```
where:
- -Cpath/— Path to the server instance.pathshould end with the name of the server to be queried for status.
- server_name— Name of the server to be queried for status.

Example

To verify the status of a server instanceprod_server_1located at\tmp\prod_server_1, type the following at the system command prompt:

mps-status -C \tmp\prod_server_1

Depending on whether the server is able to check out a valid license,mps-status返回不同的反应。

Ifprod_server_1is running and operating with a valid license, it returns the following response.
```
\tmp\prod_server_1 STARTED License checked out
```

Ifprod_server_1is unable to check out a valid license, the server returns either a warning when it is within the license checkout grace period or returns an error if it is past the grace period. For details, seelicense-grace-period.

License Server Status Information

In addition to the status of theMATLAB Production Serverinstance,mps-statusalso displays the status of the license server associated with the server you are querying. The following table lists different license server status messages from the output ofmps-status.
