Virtual
Cluster Manager (VCM)
VCM
provides an inexpensive, flexible, platform-neutral,
extensible, distributed and scalable Framework for
monitoring (& managing) mission-critical
applications and business-critical systems. It provides
unmatched levels of monitoring and event management
functions that are second to none.
VCM
comes with a standard set of monitoring and event
management components that can be used to start
monitoring and managing applications upon installation
without any additional customisations. VCM provides a
unified solution to monitor the status and performance
of an application and all it’s associated
infrastructure elements such as system, network and
database resources.
VCM as a single integrated tool can be used to
manage the diverse array of resources in an
enterprise’s infrastructure ranging from systems,
networks and databases.
VCM
provides the capabilities to remotely monitor and manage
application infrastructure elements that are
geographically distributed. It provides the necessary
tools, functions and APIs to add custom monitoring and
management functions to any enterprise application or
custom application desired.
VCM is an extensible and open-ended applications
management framework/solution.
VCM
is designed for out-of-box monitoring and collection of
performance data for different types of system
resources, system services and other popular critical
resources, based on the 80/20 Rule.
Administrators
of business applications and services must have access
to historical and current performance information to
manage growth proactively through capacity planning. The VCM product suite provides tools and functions to perform
comprehensive capacity planning and performance analysis
of the various enterprise applications and system
resources. Managers need to see the trend and graph, for
resource utilization, for presentation as well as
capacity planning to help plan future requirements.
In
short, VCM provides a cost-effective, rapidly
deployable, intuitive, easy-to-use, extensible, scalable
and unified solution to remotely/locally monitor and
manage the geographically distributed infrastructure
elements of an business enterprise.
