Telemetry data holds the key to flawless, secure, and performant digital experiences


Organizations need to build complete customer-centric environments that deliver superb, secure, personalized digital experiences every time, or risk losing out in the race for competitive advantage. Prioritizing both internal- and external-facing applications and ensuring they are running optimally is the engine behind every successful modern business.

The complexity of cloud native and distributed systems has risen in lockstep with the expectations of customers and end users. This rachets up the pressure on the teams responsible for applications. They need to aggregate petabytes of incoming data from applications, services, infrastructure, and the internet and connect it to business outcomes.


This telemetry data — called MELT or metrics, events, logs, and traces — contains the information needed to keep digital experiences running at peak performance. Understanding, remediating, and fixing any current or potential breakdown of the digital experience depends on this collective data to isolate the root cause.

Given our dependence on performant, real-time applications, even a minor disruption can be costly. A recent global survey by IDC reveals the cost of a single hour’s downtime averages a quarter of a million dollars — so it’s vital that teams can find, triage, and resolve issues proactively or as quickly as possible.

The answers lie in telemetry, but there are two hurdles to clear


The first is sorting through vast volumes of siloed telemetry in a workable timeframe. While solutions on the market can identify anomalies, or issues out of baseline, that doesn’t necessarily mean they are a meaningful tool for cross-domain resolution. In fact, only 17% of IDC’s survey respondents said current monitoring and visibility options are meeting their needs, though they are running multiple solutions.

The second is that some data may not even be captured by some monitoring solutions because they see only parts of the technology stack. Today’s applications and workloads are so distributed that solutions lacking visibility into the full stack — application to infrastructure and security, up to the cloud and out to the internet where the user is connected — are missing some vital telemetry altogether.

Effective observability requires a clear line of sight to every possible touchpoint that could impact the business and affect the way its applications and associated dependencies perform, and how they are used. Getting it right involves receiving and interpreting a massive stream of incoming telemetry from networks, applications and cloud services, security devices, and more, used to gain insights as a basis for action.

Cisco occupies a commanding position with access to billions upon billions of data points


Surfacing 630 billion observability metrics daily and absorbing 400 billion security events every 24 hours, Cisco has long been sourcing telemetry data from elements that are deeply embedded in networks, such as routers, switches, access points and firewalls, all of which hold a wealth of intelligence. Further performance insights, uptime records and even logs are sourced from hyperscalers, application security solutions, the internet, and business applications.

This wide range of telemetry sources is even more critical because the distributed reality of today’s workforce means that end-to-end connectivity, application performance and end-user experience are closely correlated. In fact, rapid problem resolution is only possible if available MELT signals represent connectivity, performance, and security, as well as dependencies, quality of code, end-user journey, and more.

To assess this telemetry, artificial intelligence (AI) and machine learning (ML) are essential for predictive data models that can reliably point the way to performance-impacting issues, using multiple integration points to collect different pieces of data, analyze behavior and root causes, and match patterns to predict incidents and outcomes.

Cisco plays a leading role in the OpenTelemetry movement, and in making systems observable


As one of the leading contributors to the OpenTelemetry project, Cisco is committed to ensuring that different types of data can be captured and collected from traditional and cloud native applications and services as well as from the associated infrastructure, without dependence on any tool or vendor.

While OpenTelemetry involves metrics, events/logs and traces, all four types of telemetry data are essential. Uniquely, Cisco Full-Stack Observability has leveraged the power of traces to surface issues and insights throughout the full stack rather than within a single domain. Critically, these insights are connected to business context to provide actionable recommendations.

For instance, the c-suite can visualize the business impact of a poor mobile application end-user experience while their site reliability engineers (SREs) see the automated action required to address the cause.

By tapping into billions of points of telemetry data across multiple sources, Cisco is leading the way in making systems observable so teams can deliver quality digital experiences that help them achieve their business objectives.

Spend Less Time Managing the Network, More Time Innovating with the Network

Cisco Exam, Cisco Exam Prep, Cisco Exam Preparation, Cisco Tutorial and Materials, Cisco Guides

As networks evolve to keep up with the requirements of a distributed hybrid workforce and the need for new B2B and B2C cloud applications, an increasingly complex workload for IT is an inevitable byproduct. Remote workers, collaborative applications, and smart building IoT devices have all added management challenges to the hybrid workplace network. IT teams, already responsible for network device onboarding, availability, and resilience, are taking on AIOps responsibilities for ensuring high application experience. They’re also picking up SecOps oversight for monitoring various endpoints for spoofing threats and malware intrusions. With this growing load of responsibilities, how is IT going to scale and not break?

The answer lies in the past as well as in the future. Twenty years ago, Cisco developed one of the first machine-learning toolsets to analyze vast quantities of telemetry collected from switches, routers, and access points to assist in technical problem resolution. The system, created by the Cisco Advanced Services team, was called Network Profile (NP). Built on top of one of the first network-specific data lakes, NP helped customers understand the current state of their networks and enabled Cisco technicians to quickly troubleshoot network issues.

Since then, Cisco has worked diligently to augment the intelligence inherent in the network. Today, the continuously evolving NP is an integral part of the Cisco CX Cloud and is tightly integrated with Cisco DNA Center. Cisco DNA Center Analytics, like NP and Site Analytics, and automations like the Machine Reasoning Engine, make network pros more effective by offloading repetitive, complex, and time-sensitive tasks that do not directly add new value to the organization.

A key value of applying Machine Learning and Artificial Intelligence engines in conjunction with volumes of operational telemetry is to do simple things simply well and thus enable less experienced NetOps technicians to handle a broader range of maintenance tasks.

Automating Compliance Checks


A great example of this intelligent automation lies in the area of compliance. Cisco DNA Center automates configuration checks of settings—such as certificates and SNMP—across hundreds of controllers. What is usually a time-consuming and tedious task is greatly simplified. Guided automations recommend fixes that IT can quickly implement with a single click. And since this scanning is always on, in real-time, technicians don’t need to remember to set aside time every week to run a network compliance scan. That’s simplification!

Simplifying Device Maintenance


Similarly, when managing thousands of networking devices across campuses, branches, and remote offices, what IT doesn’t know about lingering security issues forces technicians to be reactive rather than proactive. It takes time and expertise to keep up with PSIRT vulnerabilities and patches to network software on thousands of access points and switches.

Cisco DNA Center provides preventative measures for device maintenance. By connecting Cisco DNA Center to Cisco CX Cloud, fixes for known PSIRTs and software patches that IT can identify by existing TAC cases are shared automatically through a Cisco DNA Center dashboard with IT teams operating with relevant infrastructures. The granularity of these notifications extends from controller OS images down to specific device configurations, so only features in use are included in notifications. As a result, instead of discovering that an issue causes a network problem with a known resolution, Cisco DNA Center proactively recommends an appropriate resolution even before a problem occurs. And if a configuration is not using any of the affected features, the controllers will bypass installing unnecessary patches. The result is complexity simplified.

Moving From Reactive to Preventative


Predictive analytics with DNA Center’s Trends and Insights dashboard is an AIOps tool for monitoring the network for changes and anomalies that, while not causing an immediate issue, could become a problem in the future. For example, early warning alerts for events like a gradual increase in wireless interference, a sudden increase in the number of devices connected to the same Access Point, or an IoT device that is pulling 20% more power from a switch can help IT take preventative actions before issues impact workforce performance or network availability. By identifying the signs of looming network problems, Cisco DNA Center keeps NetOps teams ahead of issues instead of constantly chasing them—the empowerment of being proactive versus reactive.

Optimizing the Network Fabric for Application Performance


Reducing complexity with AI/ML processes that assist IT in optimizing the network enables the best application experience for the workforce and customers. Increasingly this is even more critical as applications are literally everywhere, and so are the people who rely on them to keep operations rolling and interact with the business. Gaining visibility into application usage everywhere in the distributed network enables IT to prioritize network resources for business-critical applications and deprioritize irrelevant business applications.

Take, for example, the fast-growing use of collaboration applications incorporating audio and video, screen sharing, recording, and translation. Cisco DNA Center AIOps features enable IT to proactively manage Microsoft Teams and Cisco WebEx performance. The Applications Dashboard in Cisco DNA Center displays the audio, video, and application share quality of experience for individual or team sessions for both platforms, enabling IT to quickly determine if a problem is inside or outside the network. The dashboard also provides remediation suggestions, such as increasing Wi-Fi coverage in specific areas—before operations are affected. Suppose the problem is outside the enterprise network. In that case, IT can activate Cisco ThousandEyes WAN Insights directly from the dashboard to determine the internet bottleneck or provider causing the issue, along with alternate routing suggestions to fix the performance degradation.

Simplify Networks with a Foundation of Automation and Analytics


We are weaving AI and ML capabilities throughout Cisco software, controllers, and network fabrics to simplify the management of complex networks, including innovations like AI Network Analytics, Machine Reasoning Engine Workflows, Networking Chatbots, AI Spoofing Detection, Group-Based Policy Analytics, and Trust Analytics. These solutions assist IT in directing talent to more innovative projects that add value to the organization, such as securing the remote workforce, managing multi-cloud applications, and implementing a Secure Access Service Edge (SASE) for holistic security across the enterprise.

Cisco DNA Center enables IT to hide complexity and operate massive networks at scale, securely, and with agility. The value of AI/ML in Cisco DNA Center is in the ability of the network to enable an excellent experience for IT personas, which in turn provides an optimal experience for the workforce, along with trust in knowing the network is always watching and self-adjusting.
