- 1. Copyright 2014 Riverbed Inc. Confidential.1 Tomasz Winiarski Solutions Architect EE - CISSP, CISA, CSSK, CRISC SteelCentral NPM Solution Let’s talk about visibility. Network is Rarely a culprit.
- 2. Copyright 2014 Riverbed Inc. Confidential.2 Typical process for troubleshooting an issue Helpdesk opens ticket and sends to a network engineer. Network engineer checks his tools and says it’s not in the network and forwards to server team. Server team says, my servers are fine, pass to app team. App team says, our apps are fine, pass back to Helpdesk. User calls Helpdesk about the network being slow. Helpdesk calls user and says they don’t see any issues.

Editor's Notes
- Cascade analytics allow you to respond to IT performance problems faster, even before the user calls to complain. Without analytics, IT would only start looking for the problem when the user calls the help desk. With Cascade analytics, as soon as an application metrics goes outside the normal range, and IT can start looking for the problem right away. It may even be fixed before it starts impacting user performance. In addition, analytics alert provides contextual evidence that further accelerates the triage process. Behavioral analytics are the key to accelerating problem resolution. Cascade can track dozens of metrics such as response time, throughput and number of network connections, and alert the administrator as soon as any of them go outside the normal range. Analytics are completely automatic and dynamic – you don’t need to set any hard-coded thresholds. Cascade can even detect daily and weekly behavior patterns. Analytics tracked: Connections (Active connections, Connection bandwidth, New connections); Efficiency (# TCP resets, TCP retransmissions bandwidth); User Experience (Average app throughput / connection, Average connection duration, Response time)
- Dependency Mapping -You can’t monitor what you don’t know about Uses real-time and historical traffic flows to automatically identify all components involved in delivering an application service to the end user Discovers across all tiers of a multi-tier app, including load balancers Fast, accurate, complete, easy to use and keep up to date Analytics enable proactive outage avoidance. Cascade service dashboards provide a quick view into the end-to-end health of an application or service and enable a top-down approach to troubleshooting. Application services are created using the discovery wizard which automates the process of mapping transactions to their underlying infrastructure, so that service definitions are always accurate and up to date. So when we say that we’re monitoring service health, we mean we are monitoring ALL of the components involved in delivering the service to the end user: users, web servers, load balancers, application servers, authentication and DNS servers, databases and the links between them. That’s true end-to-end service visibility. And this is a significant differentiator for Cascade.

- Detect under or over provisioned rules
- Cascade Profiler enables IT managers to determine how VoIP services are performing in conjunction with data resources in order to make effective capacity planning and optimization decisions, and improve end user experience. Supported VoIP quality metrics include mean opinion score (MOS), R-Factor, packet loss and jitter. Jitter: The inter-packet arrival variation that results from variable delay in packet transmissions; excessive jitter results in “early” and “late” packet delivery and discards at the receiving jitter buffer. Packet Loss: The number of VoIP packets that are discarded by the network due to congestion or packet corruption MOS and R-Factor describe perceived VoIP quality MOS scores range 1 to 5, where 1 is lowest and 5 is the highest perceived quality R Factor scores range from 0 to 100 Supported VoIP protocols include: Cisco SCCP “Skinny” SIP H.323
- Virtualization brings with it great promise of flexibility, cost savings, and security. Most importantly it allows IT infrastructure to dynamically adapt to the needs of applications. This value comes with a cost in the form of increased complexity for Network and IT operations. Cascade 10.0 provides network and IT operations a complete solution for managing network and application performance across all major virtualization areas.
- This series of screenshots show Cascade’s top-down troubleshooting in action and how service dashboards, discovery and analytics all play a role in accelerating the triage process. The top-down approach is much quicker and more cost-effective than looking one interface at a time like you do with many competing products. Solving a tough problem may involve digging deep into the packet level. However, some tough problems require a wide view, e.g. you can solve the problem by seeing where else it has happened.
