SAN FRANCISCO -- Netcool(R)/Precision for IP Networks(TM) V3.5 Provides Fast and Comprehensive Analysis For Increased Knowledge of IT Networks

Micromuse Inc. (Nasdaq: MUSE), the leading provider of ultra-scalable, realtime business and service assurance software announced today the availability of version 3.5 (V3.5) of its Netcool/Precision for IP Networks(TM) for auto-discovery, network topology, and root-cause analysis. The new features delivered in V3.5, which draw upon feedback from the Netcool/Precision product's rapidly growing customer base, enhance customers' overall experience in terms of user efficiency, realtime intelligence across the infrastructure, reduced cost of administration and quicker return on investment.

Today's organizations require highly accurate and realtime, detailed visibility into their service infrastructure to take their business or service management capabilities to the next level. The latest release of Netcool/Precision includes enhanced visibility into the service infrastructure through the addition of several key discovery capabilities including extended collection of server-based asset information, support for more network protocols, and greater flexibility in the configuration of discovery speed and detail. These features dramatically reduce the time needed to heal the network and ensure that customer-facing IT staff has meaningful, contextual information at their fingertips.

"Our customers have always appreciated the depth and realtime accuracy of our infrastructure discovery, as have our technology partners in the asset and configuration management spaces," said Craig Farrell, Micromuse's CTO. "The need for realtime visibility into the complex service infrastructure is critical to supporting long-term enterprise and service provider IT management initiatives across configuration, change, and problem management to name just a few. The enhanced infrastructure discovery and visualization capabilities provided by V3.5 take problem identification and resolution to the next level, providing accurate, topology-based root cause analysis."

Netcool/Precision for IP Networks is tightly integrated with Micromuse's solutions for consolidated operations management, business service management and service quality management, extending their visibility into network assets and dependencies and drastically reducing the volume of managed events through the application of topology based root cause analysis.

Netcool/Precision for IP Networks v3.5 includes a number of key new features including:

--Web-based "Network Views" GUI allows users to automatically partition the discovered topology into a set of sub-views according to users specific requirements.

--Advanced default configuration system reduces the time it takes for installation, configuration, and administration tasks for new users and those looking for less customization capabilities.

--Web-based Network Discovery Configuration and Administration GUI and wizards enables authorized users to customize discovery speed and depth to accommodate the scope of the network, the desired level of detail and any other administrator defined factors.

--Access to Micromuse system agent details, including what specific processes are running on the box, enabling robust asset reporting from network to servers using Micromuse asset reporting.

--Support for additional discovery protocols, including secure socket shell.

--Significant enhancements to root cause correlation providing greater granularity and accuracy of root cause.
