Fast, inexpensive real time
performance monitor for z/VM and VM/ESA.
ESAMON is Velocity Software's flagship performance monitor for
z/VM and VM/ESA. This technology has been well tested, and is
used in the majority of large VM installations. ZMON uses the
technology from ESAMON - but does not contain any of the historical
functions provided by ESAMON in the form of History Data.
With IBM's announced discontinuance of VM/RTM, there is a need
in smaller or less complex installations
for an inexpensive performance monitor
to provide basic performance analysis
functions.
Including over 100 different displays, ZMON was developed for
installations with a need to assess performance "now", without requiring
long term analysis or capacity planning. Numerous drill down features
are provided for in-depth analysis of existing or potential performance
problems in areas such as DASD, DASD Cache, MDC, Storage, Shared File
System, Processor, IUCV, LPAR, and many more.
Features and Benefits
Easy to Support:
ZMON operates across all releases of VM/ESA and
z/VM. Support for 31-bit and 64-bit is included. Screens such as
"SMART", "EXPLORE", and "OPS" are supplied giving users a sense of
instant familiarity to real time monitor data. ZMON, while based on new
technology, reduces the learning curve to a new technology that is both
easy to use and easy to support.
Standard
Interface: Based on the CP monitor facility,
installation requires no "hooks" into the
operating system, and no upgrades are required when you install
a new version of z/VM. Today - ZMON, ESAMON and ESAMAP
support all existing releases of VM/ESA and z/VM. This allows
you to maintain a single monitor for use with multiple systems
or images running diverse VM versions. New releases of VM are
supported immediately at availability.
Complete Display Facility:
Over 100 easily
navigated screens from high-level overviews to detailed
subsystem displays. Displays include statistical summaries, full
DASD cache analysis, SFS analysis, device analysis, Minidisk
Cache, and even seeks analysis - all critical for performance
management.
Automatic
Updates: Screens are automatically updated to
provide current performance information.
