CNE’s Node.js Agent – Monitor Node.js Application

We are all familiar with the functionality of the Node.js Agent, but what we need to familiarize ourselves is with the insights of the production systems while developing Node.js applications. And to assist us here, CNE has introduced Node.js to their existing suite of tools.

Node.js plays the role of a Monitoring application. CNE understands how crucial Constant monitoring is to avoid slowing down of the product and even more to avert downtimes. This application also monitors the details of the inefficiencies of the databases, slow 3rd party APIs and web services.

CNE introduces Node.js as a Monitoring Solution

CNE is a high-end, suite of tools designed by administrators and performance experts to improve performance, scalability and stability of enterprise applications. The CNE Node.js Agent helps you monitor Node.js applications during the production phase. It can then be determined which applications are slower than normal or producing a lot of errors. It also provides tools for troubleshooting and monitoring the application problems.

Node.js CNE – Proven Monitoring Solution

  • Monitoring performance: Reviewing the most important performance metrics to ensure stability
  • Monitoring the Code:Reporting at a code level, thus, monitoring the execution of each function at the production level
  • Monitor Server status which includes recording of:
    • Sufficient disk space on server
    • Sufficient CPU time
    • Sufficient memory
    • Reliable Network Connection
    • Request and response details of the server
    • Generate server crash reports
  • Monitoring Database operations: Reviewing the time spent in the database including noSQL datastores like Redis, mongoDB, and memcached.
  • Monitor Network connections:Monitor network connections to reduce communication delays between services
  • Monitoring error rates: This can be achieved by Generating an Error report of http request calls

Node.js server Increases Performance since:

  • HTTP module Added:Identifies and designs theHTTP module for collecting the Http calls. Support is provided to the HTTPS feature in Applicare server and to the Node.js agent.
  • Reduction in Average Response times: Calculate the time taken to complete the request along with sql or no-sql calls.Collects and records the elapsed time for the SQL calls happening in Node.js application.
  • Distributable database:Instruments various SQL(mysql, oracledb) and No-SQL(mongodb) database modules,
  • Monitoring Web Transactions: The request module is used to Monitor/collect the external web service calls, executed by the Node application
  • ART Platform:Monitor/Calculate the ART and platform information of the server
  • Reduction in Error Rate: Monitor/collect the HTTP error data released in the Node.js application
  • Average Response Time:Calculate the elapsed time of the respective http call.
  • Generate Alerts: Receive alerts to errors generated by applications, and thus enabling prompt fixtures.
  • Throughput (requests per minute):js application status would be updated per minute (custom defined), to ensure the health of the application under monitoring.
  • Control flow Transactions: The Node.js Agent monitors applications dynamically when a program is running or being executed. The Node.js runtime metrics help in monitoring the health of the Node.js process.
  • Admin Console: Applicare admin console assists in configuration and implementation of the instrument and un-instruments
  • Business transaction Manager (BTM): This feature has been designed, where admin can add few specific http, sql and web service calls to the BTM list. Thus admin incorporates a few rules that consolidate the history of data and enhance the application or the server configuration.

CNE overcomes the Challenges by:

  • User Experience Manager(UEM): This functionality is used todesign and develop the script in to the response of Node.js application.
  • Protobuf technology: This technology is integrated for secure data sharing between CNE server and Node.js agent. This technology is also used to monitor the Collection and Execution time for sql calls
  • Low Expectancy: This principle is assists in identifying the respective Http calls and thus calculating the server time spent on the particular requests.

Business Benefits

  • Broader Market Insight:By adding one new technology agent to the current suite of  tools in the Applicare project, Arcturustech opened up to a wider range of clients looking for robust and latest technologies
  • Increased Clients:Also in a very short period of time Arcturustech found the increased requirement for the Node.js solution to clients who already had the server installed.
  • Visible Scalability:Development of a Connection between the high-end technologies based servers. Thus enabling the consolidation of data featuring it as a library in runtime environment.

IOT and Stream Analytics

IoT and Stream Analytics

-by CNE Systems

In an Internet of Things (IoT) environment, machines, sensors, and devices are connected to networks and data systems. These things or smart objects generate large volumes of fast moving data with huge potential for insight generation.

This generation requires an immediate decision. Every decision has a window of time when information is valuable. Thus assigning deadlines to these decisions and if information arrives too late, the opportunity to make the call based on analytical insights is lost.

This is where we introduce/incorporate Streaming Analytics. Stream Analytics makes it easy to set up real-time analytic computations on data streaming from devices, sensors, web sites, social media, applications, infrastructure systems, and more.

  • Streaming Analytics is the ability to constantly calculate statistical analytics while moving within the stream of data. Also Streaming Analytics allows management, monitoring, and real-time analytics of live streaming data.
  • Real-time data feeds enable users to analyze constantly churning information as it changes. Viewing events as they unfold accelerates action.
  • Decision makers can detect both threats and opportunities in fast moving data and act immediately.
  • Real-time integration lets analysts immediately compare new data to historical data to put current conditions in context.
  • Nobody has to wait for information to be compiled and decisions are not delayed by drawn out data processes.
  • Streaming Analytics involves knowing and acting upon events happening in your business at any given moment.
  • Streaming Analytics can help companies identify new business opportunities and revenue streams which results in an increase in profits, new customers, and improved customer service. A Streaming Analytics platform can process millions and tens of millions of events per second.
  • Since Streaming Analytics occurs immediately, companies must act on the analytics data quickly within a small window of opportunity before the data loses its value. We will focus on the data that originates from the Internet of Things (IoT)
  • Scenarios of real-time streaming analytics can be found across all industries: personalized, real-time stock-trading analysis and alerts offered by financial services companies; real-time fraud detection; data and identity protection services; reliable ingestion and analysis of data generated by sensors and actuators embedded in physical objects (Internet of Things, or IoT); web click stream analytics; and customer relationship management (CRM) applications issuing alerts when customer experience within a time frame is degraded.

IoT: A basic discussion

What is IoT?

IoT stands for Internet of things. This is a technology which helps us to interact with things around us in several different ways. These things can be categorized as systems, static objects or machines. IoT is used for a wide variety of applications which varies from the M2M technology where in the communication is maintained between 2 machines only.

Smart meters, home router, TV, light control, A/C control etc are few applications of IoT. IoT has covered most the industries right from energy, manufacturing, healthcare, telecom and transportation.

3 Main aspects of IoT:

The three main aspects of IoT include connectivity, remote management and security. IoT applications bring in a large number of advantages but there are many security aspects which need to be taken care by the user of IoT enabled devices.

The concept of clouds and mobile app has given an all new perspective to the existence of IoT. Continue reading

It’s Industry 4.0 now!!

Industry 4.0 is currently immensely popular with a very good reason. It is termed as the “factory of the future” with its interconnected components and processes. This is also with reference to the great industrial revolutions of the past

What is Industry 4.0?

Industry 4.0, Industrie 4.0 or the fourth industrial revolution, is the current trend of automation and data exchange in manufacturing technologies. It includes cyber-physical systems, the Internet of things and cloud computing. Industry 4.0 creates what has been called a “smart factory”.
1st Revolution: Water Steam
2nd Revolution: Electricity
3rd Revolution: Automation
4th Revolution: Cyber physical Systems

The core of the Digital Industry 4.0 is highly intelligent connected systems that create a fully digital value chain, the 4th industrial revolution enabled by the Industrial Internet of Things (IoT).

Every technological Revolution has altered the way we live, work and relate to each other. The difference in the scope of visualization of a machine in the current generation to that of it a couple of years ago are gigantic. These days it’s all about sharing information and the internet has completely changed the way we access and share information.

How can 4.0 be enabled?

Overview of Functioning of Smart Factory:
Data is collected with a variety of sensors.
Data is collected from the energy generated by the machine to the damages it is bearing.
The factory is self-aware. “It knows, when the man needs rest, it knows when a machine needs to be replaced or repaired, it knows the humidity, temperature, everything.
This data that is collected goes through pre-analysis (meaning to convert it to a language that can be processed for analysis) and then the analysis happens and course correction is initiated wherever required,”

Smart Factory

From a Blog to CMS to a Website – WordPress done it all

What is a Blog?

Says Wikipedia – A blog is a discussion or informational website published on the World Wide Web consisting of discrete, often informal diary-style text entries (“posts”). Posts are typically displayed in reverse chronological order, so that the most recent post appears first, at the top of the web page.
Further explaining, Blogs usually focus on a particular topic such as Mobile Technology, Software technology, sports or even politics. The focus could range from one narrow subject to whole broad range of subjects.
A Blog consists of:
• The main content area with articles listed chronologically, newest on top.
• An archive area that consists of older articles
• Comments area where people can leave comments about the articles
• The sometimes included “blogroll” section that lists the links to other related sites.

Then what is a CMS?
CMS is a software application that can be used to manage, edit, and upload the content on the website. Several other tasks performed by a CMS includes:
• Regulating the content displayed
• No. of times the content is showed to the user
• Managing how the content connects or interacts with other element of the website
• Hence lesser technical individuals with lesser technical knowledge can also manage the content easily

Required – A blog writer for a Real Estate website

For our website that deals with Real Estate, we require a blog writer. The reason we have a blog is to create content that resonates with our website, thus directing visitors to our site. For this strategy to work, the key points to keep in mind while writing articles for the blog are – SEO, Relevant Topics of General Interest, and Content Quality.

Layers

SEO – Search Engine Optimisation

SEO is a very important tool to drive visitors to our site. The blog article should have popular keywords to do with Real Estate. These are words that people will search for when using popular search engines like Google when looking for content. So for example, if you would like people searching for “Greater Chicago area properties” to see your content, then these words should be present in your article. The blog writer should also take advantage of the blog software features for SEO. For example, if you are using WordPress, it allows you to specify keyword “Tags”.

Relevant Topics of General Interest

The important words here are Relevant & Interest. You could write a great article on the mineral content of soil in the Greater Chicago area. That would be a scholarly and important article. And it would fit the mandate for SEO. But how many people would read it? On the other hand, given the election fever going around, a blog article on probable movements in property prices if Trump were to become President is likely to get more readers. Thus getting ranked higher in Search engine results, and sending more visitors to the website.

Content Quality

Once the topic is zeroed in on, a quality article must be delivered. Total objectivity is a goal to aspire to while writing your article – but only if you are writing for Wikipedia. A well researched and objective article is definitely what we are looking for, but with that touch of subjectivity. That whiff of fragrance, that dash of spice. We want you to give the blog article your own personal touch.

If you think you have what it takes, get in touch with us with your sample work, and we’ll be happy to get you onboard.

Smart Electric Meters over a ZigBee network

Given the awareness about Renewable Energy, Energy Independence, Energy Neutrality and the like – it came as no surprise that when a little remote village in central India decided to get itself some electric power, it considered other options to just getting itself “on the Grid”.

Follows is a brief description of the favoured scenario:

  • Independent electrical network for the village – based on solar energy, biogas, and diesel iotschematicgenerators.
  • This choice of energy was because it was a sun-blessed agrarian village like everywhere in India.
  • Equipment and Operations would be on an Own or Lease model by individual villagers, as opposed to State ownership.
  • The Village Administration (called Panchayat in India) would also like some electrical power for consumption in street lights, community water well pumps, school building and panchayat building electrification, etc.
  • The Panchayat would need to pay the individual power generating individuals for the power supplied.
  • Therefore it is critical that their contribution to the village grid had to be metered and accounted for.

Optimal Use of Wireframes in Eliciting Business Requirements

The debate continues on whether it is Wireframes or Functional Requirements Definition document. Since I personally like “wireframing” my article would be slightly biased towards the same. Adding to the same, both the processes tend to complement each other. To start with let’s see where exactly (i.e. which stage of the software cycle) the wireframing process fits in.

Being a part of the initial phase of the development cycle, wireframing is a process which helps in organizing the elements of a website. The wireframe acts as a prototype that shows the placement of page features, such as header, footer, content, sidebars, and navigation. It also specifies the placement of the elements within these content areas. If you want to develop a site that accurately matches the client’s requirements and minimize project revisions, wireframing will keep you on track. Thus it provides to everybody a visual representation of the website and displays a clearer picture of the design of the website layout. The key is to keep it simple enough to be clear to the client and to be flexible for the designer, but detailed enough to guide the programmer.

A wireframe should not only provide a final look of the desired website but also allow revisions to be made easily and early on in the process.

Wireframing brings the following key benefits:

  •  It gives the client an early, close-up view of the site design (or re-design).
  •  It can inspire the designer, resulting in a more fluid creative process.
  •  It gives the developer a clear picture of the elements that they will need to code.
  •  It makes the call to action on each page clear.
  •  It is easy to adapt and can show the layout of many sections of the website.

Like all other stages, it’s nice to follow the nice practices in developing a wireframe too.

  • It’s recommended to work in greyscales. Different shades of gray help in categorizing various elements, shapes and outlines. working in grayscale helps maintain focus on the primary function of the process, which is to finalize the layout, not the design
  • Requirement Understanding: A clear understanding of the client requirements goes a long way. User responses thus page outputs, calls to actions need to be very clear thus making the wireframes very clear.
  • Requirement Gathering: Navigation sections, header, footer, logos, ads etc if collected in advance help in the accuracy of the wireframe designs.

List of different tools that i use are:

  •  Hand sketching on paper
  • Visio:  Flowchart software.
  •  Web prototyping software, such as Gliffy or Balsamiq.
  •  Graphics software, such as Photoshop or Illustrator
  •  (X)HTML wireframes are almost like actual sites themselves.
