Resource Measurement Facility
Resource Measurement Facility (RMF) is a software monitor from IBM for the z / OS operating system. In addition, RMF collects data for long-term performance analyzes and capacity planning. RMF consists of the following components:
- Monitor I data collector: this collects data at adjustable intervals from one minute to one hour and writes SMF data records of types 70 to 78. A data space can be generated for monitor I, which allows SMF data to be buffered and processed directly by the RMF postprocessor allow.
- Monitor III data collector: this collects data for short-term data analysis. Data is collected at intervals of 10 seconds to 10 minutes. The data is stored in Monitor III VSAM datasets and the Monitor III In-Storage Buffer. In addition, certain SMF data types such as coupling facility data are generated via the Monitor III data collector.
- Monitor II is the original snapshot monitor in RMF. Furthermore, SMF Type 79 data can be collected by Monitor II. The snapshot monitor has lost its importance in recent years.
- RMF Postprocessor is the evaluation program for RMF SMF data types 70 to 78. The RMF Postprocessor generates a large number of tabular and textual reports that can be evaluated for detailed analysis of the z / OS performance.
- RMF Spreadsheet Reporter is an extension to the RMF postprocessor and allows selected data to be displayed in spreadsheet applications.
- Monitor III Reporter is the evaluation tool for the data collected by the Monitor III data collector. The MOnitor III Reporter is an ISPF application that supports short-term data analysis. Monitor III is able to display the data of all systems of a parallel sysplex.
- RMF PM and the RMF web portal are workstation extensions to Monitor III and enable any z / OS system on which RMF data is collected to be displayed.
