The document discusses modern network performance management for enterprises, emphasizing the need for high scalability, flexibility, and extensibility in monitoring solutions. As businesses transition to private clouds and virtual services, the reliance on efficient network performance increases, necessitating advanced tools for capacity planning and incident management. A modern multi-tiered architecture is proposed to enhance performance while reducing costs, enabling organizations to proactively manage the complexity of their networks.

Challenges•Application workloads are increasing, especially as customers, partners and suppliers interact and transact business with youvia your website. So network performance and availability from your web server to your internal systems are critical to your business more than ever. •Data center consolidation and the transition to Private and Hybrid Private-Public Cloud are lowering capital and administrative costs and enabling business agility. But this increases your business’ reliance on your network’s availability and performance as the volume and types of traffic and network utilization increase. •Virtual Desktop Services can lower administrative and end-user support costs and increase security, but this also increases network traffic and end-users’ reliance on the network for personal productivity. •Teleconferencing and Voice-over IP can lower travel and telecomm costs while improving collaboration. But this increases network traffic and the need for greater control over who uses your network, how they use your network and how to assure quality of service. •As your network grows and gets more complex, your operations and engineering team needs a way to make capacity planning, monitoring and incident handling easier and more efficient. Overcoming these modern network challenges requires a modern network performance management solution.

Modern network monitoring and
analytics solution•Assuring satisfactory application service delivery, good user experience and your ability to maintain operating and service level agreements are paramount to your business’ revenue, customer satisfaction and your reputation. •Dumb pipes, siloed tools and reactive monitoring of your network domains are inadequate for today’s enterprises. •Instead, instrumentation and analytics must be intelligent and end-to-end across the entire service delivery path so you know how and where network incidents impact users and how trends will impact users and business processes unless they are proactively addressed. •This requires a single performance management solution that can monitor and analyze a massive amount of granular key performance indicators from a wide range of multi-vendor network equipment and across all network technology domains.

• Monitoring today’s large, complex networks
requires tools built on an entirely new Multi-
Tiered Architecture that provides very high scale
at low cost.
• Based upon a centralized cluster of host servers –
each dedicated to a specific function – this
architecture enables very high performance data
collection and analytical processing that requires
half or less than half the host servers of older-generation
monitoring tools.
• The architecture’s efficient polling engines
(i.e., collectors) scale monitoring linearly and at
low cost by adding a fraction of additional servers
required by older-generation tools.
• Newer data base technology enables
warehousing of hundreds of terabytes of data on
a small host foot-print, making them available for
deep analytics for incident management and
trending for capacity planning and proactive
problem avoidance.
• Dashboards are optimized for reading and visually
correlating a massive amount of key performance
indicators. The architecture is designed to
eliminate bottlenecks found in older-generation
monitoring tools to ensure instant population of
dashboards and reports with metrics and analysis.
