VitalSigns for VM | VS/VM | Overview
Monitoring your VM system should mean more than being alerted, after the fact, that something has gone wrong. IS departments need a low-overhead tool that provides alert monitoring as well as long-term retention of data for developing trend reports and baseline information.
Use VitalSigns for VM as your Solution. Get . . .
- Customized exception reporting. You know your system better than anyone. We let you set the exceptions to be the best for your situation.
- Modeling and “what if” analysis to determine the best location for VSE files and CMS minidisks.
- Online graphs and tables to show real-time and recent performance data. This provides IS personnel with easier-to-see information that can help them resolve trouble reports.
- VitalSigns for VM also has its own archiving to tape system. This allows you to retain a great deal of history for analysis in a static media with an easy recall system.
- The ability to extract data for use by other software.
Online Displays and Controls
The VitalSigns online system creates online reports of current and recent performance. It provides for operational controls for VitalSigns and for executing CP and CMS commands.
You can view performance data in both tables and graphs. Users control the time periods reported, the refresh intervals, recall of recent history, automatic cycling through multiple displays, how data is sorted, the resolution or level of summarizing, and more.
Many report displays allow you to drill down to details regarding individual devices and user IDs over the previous hour.
The online system is navigated via a mouse and menus. The menus can be bypassed with “fastpath” commands at any VitalSigns or CMS command line.
3270 terminals using VitalSigns for VM to display online reports have access to Power Windows, PC-style windows, so multiple reports can be viewed simultaneously.
Reporting, Storing, and Transferring Historical Data
The Performance Database Reporting Facility (PDB) is a batch utility that reports, archives, and restores historical data for VitalSigns for VM.
The PDB archives performance data to tape and maintains a tape catalog so that it can issue mounting requests when asked to use the data again.
To report performance over long-term history, the database facility calls up data from disk and tape to create graphs and tables that describe system activity over weeks, months, quarters, years, or any other interval. Report formats are defined in procedure files that users can edit to suit their needs.
The database facility can restore data from tape to the performance database on disk. The facility can also extract data from tape to standard CMS files, or dump data from the performance database on disk to CMS files. The CMS files can then be used as input for other analysis software, Lotus 1-2-3®, SAS®, and Excel®, for example.
SEEKMISER/ESA is a tool for minimizing seek time on your DASD devices, thus speeding I/O response on your system. Controlled via windows and menus on the Online Subsystem, it reports and analyzes seek data collected by the Process Subsystem.
SEEKMISER/ESA displays provide information about:
- Optimizing minidisks on a DASD volume.
- Balancing I/O activity over multiple volumes.
- Obsolete minidisks that can be deleted.
- Over- and under-allocated minidisks that should be reduced or enlarged.
- Fragmented minidisks that should be compressed.
- How VSE files can be moved to speed seek time.
What-if modeling allows you to try different DASD devices or minidisk layouts before making changes.
