9.4 Monitoring ProtecTIER through ptmon This section describes how to query the ProtecTIER system through the CLI using ptmon. The ptmon is loaded during the installation of ProtecTIER software and is located in the /opt/dtc/app/sbin/ directory. Make sure you are in this directory when running ptmon commands from the command prompt. Usage Use the ptmon command to query the system via the command line interface (CLI), and to receive various statistics about the ProtecTIER system. This information can provide valuable insight to the administrator about the performance, capacity, configuration and operation of the system, and can be accessed by other management applications. You can print the usage information message by running ptmon with no arguments. The usage information message will also be printed when the arguments list is malformed.
