+# cpuplugd mon_fsstatd tools test
+
+cpuplugd: Daemon that manages CPU and memory resources based on a set of rules.
+Depending on the workload CPUs can be enabled or disabled.
+The amount of memory can be increased or decreased exploiting the Cooperative Memory Management (CMM1) feature.
+
+## Getting started
+
+The test case contains the following scripts:
+
+- **cmm.conf** _configuration file_
+- **cpu.conf** _configuration file_
+- **cpuplugd.conf** _configuration file_
+- **cpuplugd.sh** _verification of cpuplugd tool_
+- **cpuplugdcmm.conf** _configuration file_
+- **cpuplugdtemp.conf** _configuration file_
+- **mon_fsstatd.sh** _mon tool tests_
+
+## Prerequisites
+
+z/VM guest or LPAR must be prepared to be populated with guest OS
+
+## Installation
+
+Scripts are to be copied into the target test system
+
+## Running the tests
+
+runtest/s390x_tests contains all the necessary commands to be executed:
+`./cpuplugd.sh`
+`./mon_fsstatd.sh`
