IBM® z/OS Management Facility (z/OSMF) provides a framework for managing various aspects of a z/OS system through a Web browser interface. By streamlining some traditional tasks and automating others, z/OSMF can help to simplify some areas of system management and reduce the level of expertise needed for managing a system.
Most functions of z/OSMF area are provided through plug-ins, which you can choose to enable when you configure the product. Choosing the Resource Monitoring plug-in adds the Resource Monitoring and the System Status tasks to the Performance category.
The Resource Monitoring task allows you to monitor the performance of the z/OS sysplexes, AIX® system complexes (System p®), Linux system complexes (System z® and System x®), or Windows system complexes ( System x) in your environment. You can monitor the supported metrics, create and save custom views of the metrics, and display real-time data as bar charts.
For z/OS sysplexes, the Resource Monitoring task takes its input from the RMF™ Distributed Data Server (GPMSERVE). To monitor several sysplexes, ensure that each sysplex has an active Distributed Data Server.
Similarly for AIX, Linux or Windows system complexes, the Resource Monitoring task takes its input from the RMF XP GPM4CIM started task, which is a cross platform Distributed Data Server on a z/OS system that gathers data via connected CIM servers from the systems to be monitored.
Before you can use the Resource Monitoring task, you must define the sysplexes, system complexes, or images that you want to monitor. For this purpose, you use the System Status task. This task provides a comfortable way to assess the health status of all systems in your installation at a glance. Figure 1 presents a sample list of z/OS sysplexes. You can add all target sysplexes, system complexes, or images you want to monitor to this list.
The Performance Index Status column provides a red, yellow, or green indicator for the health of the sysplexes, system complexes, or images. If all service class periods on the systems are meeting their goals (that is, they have a performance index of less than or equal 1), the status is green. If at least one service class with importance 1 or 2 misses the WLM goal, the status indication is red. In this case, you can figure out the reasons by looking at the details on the respective sysplex, system complex, or image, using the Resource Monitoring task.
A Monitoring Dashboard is a customizable view containing a set of performance metrics. You can create and save your own dashboards or open and modify the predefined dashboards shipped with the z/OSMF Resource Monitoring plug-in.
Figure 2 shows how you can use the Resource Monitoring task of z/OSMF to monitor the common storage activity of a sysplex, system complex, or image.
A comprehensive online help is provided for each panel. Tooltips, descriptive texts as well as error, warning, and information indications will guide you through the panels and ensure an intuitive user experience.
