Figure 2-1.MON-RTM Overview (Real-time Processing)
RTM: MON-RTM can monitor and record any disk request performed on a data set, or volume. MON-Explorer has an optional database tier that can be used to collect storage manage- ment events for historical and trend analysis. The mainframe based MON-RTM compo- nent monitors real-time storage management events using the DADSM POST processing exit, and feeds storage event records to a history database that resides on the ExplorerHDB server. The Explorer PC-GUI application can use the database for Storage Analysis and Trends evaluation.
The Explorer History Database (MON-ExplorerHDB) service runs on a Linux server. The service captures the records produced by MON-RTM and writes the records to a MySQL database. MON-ExplorerHDB is a Java application and therefore can potentially run on any platform that provides a Java Runtime Environment (JRE).
Once installed and configured, MON-ExplorerHDB has been designed to operate continu- ously in the background as a Unix daemon service. For more information about the setup and configuraiton of MON-ExplorerHDB and the PC-GUI application, examine the MON-Explorer User’s Guide.
DADSM Events: RTM is not limited to producing records for MON-Explorer. The system interface used by this component sees the success or failure of every storage management request made in the system. Your RTM rules can log event failure records, write TSO messages to storage management personnel, or an send Email or Text messages depending on the severity of the event. For example, The “RTM Examples” show how to capture “VTOC full” and “Duplicate Data Set” conditions.
HSM Records: While the batch component of Monitor can read the HSM control data sets, and log files after a log switch occurs, SCC Monitor/Realtime can access the HSM records being writ- ten as SMF data. These records provide real-time access to HSM events. Like the DADSM events, your rules can be used to log notable events or notify the storage man- agement group of a critical problem.
Real-time Data Acquisition and Reporting: RTM uses the DIF rules language. The rules have access to a wealth of information related
to the DADSM request. This information can be used to produce records associated with each storage request. The records can be written to log data sets which can be used as input to user written SAS or EZ-TRIEVE programs, and/or downloaded to PC files.
