Innovation and Superheroes: The Importance of Origin Stories - Cisco Certifications


I especially appreciate the origin stories about how these characters came into being and evolved over time. We all know mild-mannered reporter, Clark Kent, originated from the Planet Krypton and evolved into different variations of Superman. Bruce Wayne was born to wealthy parents who were killed by a small-time criminal when he was young. Through relentless physical and mental training—and a scary outfit—he evolved into Batman, eventually joined by Robin to rid Gotham City of evil forces.

In many ways, the origin stories of superheroes parallel the narratives of history’s greatest innovations, including today’s amazing digital solutions. All link back somehow to an origin story many years, decades or even centuries ago.

And like with superheroes, sometimes the innovation itself disrupts an entire industry overnight, and sometimes industry gradually develops a magical new way to overcome an age-old problem, whether it’s with a new technology (sensors), combination of technologies (smart phones), or novel business models (Uber or Netflix).

The Origin and Evolution of the Phonograph


Let’s step back in time to some innovation origin stories, see how they evolved into modern-day innovations, and how we can learn from them for what’s possible in the future.

For example, the phonograph was invented in 1877 by Thomas Edison. This was the first device capable of reproducing recorded sounds—an unbelievable breakthrough at the time. However, Alexander Graham Bell’s Volta Laboratory later made vast improvements on this invention before another innovator, Emilie Berliner, advanced the recording surface from cylinders to flat discs with spiral grooves.  Each iteration of improvement was an innovation in its own right, yet still linked historically to that first, scratchy-sounding phonograph. Now we have digitized MP3s, and no doubt there are new sound waves of innovation emerging somewhere nearby.

Further, Edison originally didn’t even think music was one of the top use cases for the phonograph. He thought his invention would be more valuable for letter writing and dictation, phonographic books for the blind, and the recorded voices of family members who could “live on” after they died.  It took many incremental advances before innovators turned the phonograph into jukeboxes where listeners could select their music with the drop of a coin.

For us today, “innovations” aren’t just about the technology, but often about the marrying of that technology to new business and consumption models for the content. In the evolution of the phonograph, one final and critical component was needed:  a new format of music. In the 19th and early 20th centuries, people typically listened to live music, and there was little recorded reference point before that. Certainly no mass market recorded options.

The phonograph required songs to be shorter to fit within the device limitations. The innovation also lies with how music changed and adapted to the new format.   “The three-minute pop song is basically an invention of the phonograph,” says Mark Katz, a professor of music at the University of North Carolina at Chapel Hill, and author of Capturing Sound: How Technology Has Changed Music.

The Innovation Story of Synthetic Fertilizer


Let’s now take a look at another origin story of how a new technology was born from an existing problem and business opportunity – synthetic fertilizer.

During the Industrial Revolution as more people moved to new factory jobs in cities, rural populations diminished along with the farming communities. This created a new problem for business and society: how to feed growing urban workforces with fewer farmers.  Realizing nitrogen’s critical role in plant growth, scientists in 1909 developed a new chemical process to create the first synthetic fertilizer. Basically, they extracted nitrogen from the air, converted it into nitrate, and injected it into the ground to fertilize crops. This ushered in a new era of modern agriculture and farming practices where food could be grown much more productively, helping to solve the problem of feeding burgeoning populations in cities.

However, sometimes dark forces can overtake a positive innovation, just like a superhero.  Nitrates and derivative innovations were also used to manufacture a new generation of weapons for modern warfare, and led to new environmental challenges: When these chemicals are introduced into bodies of water, they can have toxic impacts on aquatic life.

The Ongoing Super Sage of the Wheel


What happens when innovation occurs but the market isn’t ready to adopt it?  Let’s look at one more iconic example to solve this puzzle – the wheel. Historians believe wheels were first created as potter’s wheels around 3500 B.C in Mesopotamia. This was some 300 years before some creative thinker decided wheels could be used for chariots, and thus introduced a whole new way of transforming transportation.

Since then, the wheel has stood as a universal example of an invention and an innovation that has had myriad evolutions altering so many aspects of society over time. Wheels have been used in vehicles, airplanes, used in pulleys for construction, wheels have revolutionized so much of our world.

Discover Meraki APIs for Location Analytics, Cameras, and Network Health - Cisco Certifications


Meraki wireless networks and security cameras are deployed in large numbers of retail outlets, hotels, campuses, and enterprises. Meraki wireless networks connect many business-critical devices, including Point-of-Sales devices, and provide internet connectivity to visiting customers. The Meraki camera provides reliable security with local and remote live viewing capabilities from Meraki cloud hosted dashboard. Both are very easy to deploy, configure, and manage via a centralized cloud management dashboard.

Meraki wireless access points and security cameras, beyond their basic functionalities, also provide valuable insight into foot traffic and behavior patterns of users. Meraki Access point collects user location information from nearby smart devices, enabling location-based analytics.

Meraki camera utilizes a powerful onboard processor to analyze video and provides valuable foot traffic insights by detecting persons using computer vision. Location insights provided by these Meraki devices enables businesses to provide better customer engagements, increase retail store traffic, and drive revenue. Meraki network location analytics and camera analytics are exposed to business owners via an easy to use Meraki dashboard.

As Meraki wireless network is enabling core business capabilities, monitoring of network health and maintaining low network latency becomes very critical to the operations team. Meraki Wireless Health features simplifies monitoring and root cause analysis of issues for all connected clients from the Meraki health dashboard. The dashboard provides a snapshot view for 1 hour, 12 hours, 1 day, and 1-week durations, along with various drill down capabilities to help identify issues.

Rich APIs for location analytics, health, and camera


Meraki pre-built dashboards for location analytics, camera analytics, and health monitoring are very useful and sufficient for many organizations. But some organizations have more advance use cases and want to retain granular data for longer periods of time. Historical data from Meraki, when combined with other business related data like Point-of-Sale, can provide very useful business insights. To enable these advanced use cases Meraki also supports rich APIs for location analytics, health, and camera analytics. These data sets can help business solve complex use-cases like:

  • How much do foot traffic and sales increase during promotions?
  • What is typical queue size on cash registers during specific hours of day?
  • How many devices successfully connected (or failed to connect) to the network in specific locations throughout the business?

Merakibeat Plugin collects data from the Meraki API and stores it in an analytics database


The DevNet and Meraki teams worked together to create the Merakibeat plugin, data pipeline, and reporting dashboard based on open source technologies like Elastic Beats, Elasticsearch, and Kibana. The Merakibeat plugin enables consumption of data from Meraki wireless health, location analytics, and camera API, and stores this data in an analytics database like Elasticsearch.

Key open source components for data pipeline include:

  • Elastic Beats is an open source platform for data shipper. The lightweight beats agent sends metrics to Elasticsearch. Beats is very flexible framework that supports pluggable input-output plugins.
  • Merakibeat is a DevNet community contributed input plugin that can write data to any of the Beats supported output data sources like Elasticsearch, Kafka, MongoDB, Redis etc. (complete list)
  • Elasticsearch is an analytics data store that saves historical data for further analysis and reporting.
  • Kibana is a visualization tool for Elasticsearch, that enables creating custom reports and dashboards.
  • Business metrics, like point-of-sale data, can also be ingested into the same analytics datastore to enable data analysis of business metrics, network health, and location analytics.



The DevNet team, working with Meraki engineers, developed a custom Beats plugin and reference data pipeline for Meraki APIs. This Merakibeat plugin has three sub modules –

  • Meraki Health API module polls health APIs at configured intervals and fetches connection and latency status at network, device, and client levels. Polling interval and metrics to be collected can be configured using a config file.
  • Location analytics scanning API supports pushing location analytics metrics to registered endpoints. The Merakibeat plugin starts a listener that accepts scanning data posted on a callback hook. The user needs to expose scanner data endpoint on external network and register callback endpoint in Meraki dashboard.
  • Camera API: The Merakibeat camera module polls camera APIs at configured intervals and fetches average count of user presence and entrances in specific camera zones or full camera view.

Kibana is configured as a visualization tool for Elasticsearch, and we created a custom dashboard for wireless health status reporting. The dashboard shows different charts, like average success/failure ratios and network latencies. These charts can be viewed for various time duration (like 1day, 1week, 1month etc.) or specific date/time ranges. The Merakibeat GitHub repo also includes pre-created dashboards for Kibana that can be easily customized for user’s requirements.
