The RLM Web Server
RLM Embedded Web Server
The RLM server contains an embedded Web Server which can be used to perform most administration of the RLM server itself. The web server contains the functionality of all the rlmutil-based utilities except rlmhostid. The web server allows you to retrieve server and license status (similar to rlmstat), cause the servers to re-read the license files (rlmreread), switch debug (rlmswitch) or report log (rlmswitchr) files, move the current report log file to a new name (rlmnewlog), or shut down the license servers (rlmdown). Using this web-based interface, you can administer the license servers from any platform, and you do not need to install the RLM utilities - you only need a web browser.
Important
Beginning in RLM v16.0, HTTPS is now used by default (HTTPS support was first added in v15.1). See Enabling HTTPS in the RLM Web Server for more details
In addition, the web server allows you to view ISV option files (with Manage permissions; from the action menu ⋮ of each ISV server), and the global RLM option file (as an Admin; from the Settings menu). Also, the web interface allows you to view the recent debug log information from any of the servers (via the action menu ⋮) if you have Manage permissions. The reread and shutdown commands are possible with the Manage permission, while the View user can see the status and usage for running ISV servers. See: Access Control to the RLM Web Interface for more on access permissions.
The web server is started automatically on port 5054 when rlm is started. To use the web server, simply point your browser to: http://ServerHostName:5054 and select the operation you would like to perform. You will be prompted for any required information.
Note
For earlier versions of RLM (15.2 and below) you may need to use http://ServerHostName:5054 to access the management interface.
If you would like to run the web server on a different port, specify the -ws NNNNN command-line argument when starting rlm, where NNNNN is the desired port.
The RLM web server is 100% self-contained in the rlm binary; no additional html files are required for operation.
Warning
In RLM v14.1, RLM v14.2 and RLM v15.0 the web server is disabled if the user running RLM is root or an admin user.
The remaining sections will describe some of the main functions of the web interface.

Diagnostics
Click the Diagnostics tab to view the diagnostic information for the RLM server. This page is very useful for troubleshooting any issues you may be experiencing with the license manager. In addition to all diagnostic information being available in the browser, you have the option to Download the diagnostics to your local machine if you need to send this in to your software support team for troubleshooting.
