System Status and Resource Monitoring
The System Status and Resource Monitoring tasks 1, introduced with z/OSMF V1R12, allow you to monitor the performance of your systems from the convenience of one location. What once took many minutes and required significant skill, reading performance data for multiple systems, can be done in seconds with the System Status and Resource Monitoring tasks.
System Status task: Key Features
The System Status task, which requires the RMF™ feature of z/OS, is an RMF-based workload reporting application that displays information about the systems you define. The System Status task:
- Allows you to specify the z/OS® sysplexes, AIX® system complexes (System p®), Windows system complexes (System x®), and Linux system complexes (System z® and System x®) to be monitored by the Resource Monitoring task. 2
- Combines data from an entire sysplex into one performance indicator so that you can quickly assess the performance of the workloads running on the z/OS sysplexes in your environment.
- Allows you to link directly to the Resource Monitoring and Workload Management tasks so that you can view detailed performance data or view the active WLM service definition, the active WLM service policy, and the WLM status for the sysplex. 3
Resource Monitoring task: Key Features
In the event of system performance issues, you can use the Resource Monitoring task to drill down to information about connectivity, performance index status, common storage, and more. The Resource Monitoring task:
- Provides real-time performance status for the sysplexes and system complexes defined in the System Status task. 2
- Uses RMF Distributed Data Servers (DDSs) running on any supported z/OS release to gather data to display, including most of the data available in RMF Monitor III.
- Uses z/OS RMF Cross Platform (RMF XP) Distributed Data Server, which allows you to monitor operating systems that can run on an IBM® zEnterprise® System, including the zEnterprise BladeCenter® Extension (zBX). 2
- Allows you to combine performance metrics of various platforms in the same dashboard so that you can quickly view the overall status of the zEnterprise ensembles. 2
- Provides predefined monitoring dashboards that you can use to view different performance metrics, which can be grouped and arranged flexibly.
- Allows you to define and customize your own monitoring dashboards to create cross references, correlations, and advanced filtering for focused monitoring.
- Allows you to link directly to the Workload Management task so that you can view WLM service definitions. This provides easier navigation and enables a more productive experience for systems programmers, operators, and others using z/OSMF. 3
- Allows you to retrieve and view performance data that the RMF Distributed Data Server has collected in the past for the metric groups contained in a monitoring dashboard. 4
- Allows you to export the data collected in monitoring dashboards into CSV format files on your local workstation, enabling further data evaluation using a spreadsheet application. 4
- As of z/OSMF V1R13, the name of the Sysplex Status task was changed to System Status, and the name of the Monitoring Desktops task was changed to Resource Monitoring.
- As of z/OSMF V2R1, the data gatherers for Windows system complexes (System x) are integrated into z/OSMF along with the data gatherers for AIX (System p) and Linux (System z and System x) system complexes, which were integrated in z/OSMF V1R13.
- In-context application linking between the Resource Monitoring task and the Workload Management task and between the System Status task and the Workload Management task is provided as of z/OSMF V1R13 with APAR PM74508 and APAR PM74517.
- This capability is provided as of z/OSMF V2R1 with APAR PI08825.
