Real-time baseline anomaly detection

The screen capture demonstrates the real-time baseline and anomaly detection based on industry standard sFlow streaming telemetry. The chart was generated using sFlow-RT analytics software. The blue line is an up to the second measure of traffic (measured in Bits per Second). The red and gold lines represent dynamic upper and lower limits calculated by the baseline function. The baseline function flags "high" and "low" value anomalies when values move outside the limits. In this case, a "low" value anomaly was flagged for the drop in traffic shown in the chart.

Writing Applications provides a general introduction to sFlow-RT programming. The baseline functionality is exposed through through the JavaScript API.

Create new baseline 
baselineCreate(name,window,sensitivity,repeat);
Where:
  • name, name used to reference baseline.
  • window, the number of previous intervals to consider in calculating the limits.
  • sensitivity, the number of standard deviations used to calculate the limits.
  • repeat, the number of successive data points outside the limits before flagging anomaly 
In this example, baseline parameter values were window=180 (seconds), sensitivity=2, and repeat=3.

Update baseline
var status = baselineCheck(name,value);
Where:
  • status, "learning" while baseline is warming up (takes window intervals),  "normal" if value is in expected range, "low" Continue reading

We’ve Added a New VMWare Course to Our Video Library!

VMware Cloud on AWS is an on-demand service that enables you to run applications across vSphere-based cloud environments with access to a broad range of AWS services. Powered by VMware Cloud Foundation, this service integrates vSphere, vSAN and NSX along with VMware vCenter management, and is optimized to run on dedicated, elastic, bare-metal AWS infrastructure. With this service, IT teams can manage their cloud-based resources with familiar VMware tools. This course is 2 hours and 25 minutes long and taught by Joseph Holbrook.

 


Why You Should Watch:

VMWare Cloud on AWS allows you take advantage of what you already know and have in your existing infrastructure. Your existing skills, investment in training, operational practices, and investment in software licenses remain relevant and applicable when you move to the public cloud. As part of that move you can forget about building & running data centers, modernizing hardware, and scaling to meet transient or short-term demand. You can also take advantage of a long list of AWS compute, database, analytics, IoT, AI, security, mobile, deployment and application services.


What You’ll Learn:

This course covers the VMware Cloud on AWS service overview, Prereqs, Licensing, SDDC, Hybrid Linked Mode, NSX, Compute Options, Connectivity Continue reading

GETTING STARTED: ANSIBLE TOWER’S API

Getting-Started-Ansible-Tower-API

Welcome to another entry in the Getting Started series. The API (Application Programming Interface) or, as I like to refer to it, the Magical Land of Automation Information, can be used in quite a few ways. In this Getting Started post, we will be discussing Red Hat Ansible Tower’s API and how you can use it to extract information to utilize in your playbooks and other tools.

The idea for this blog post came about when David Federlein was developing a new Ansible Tower demo and presentation. I will be making references to that codebase, which you can follow along with throughout this post. Please note that this demo utilizes Vagrant and VirtualBox so you’ll need to have those applications installed if you would like to stand up the demo yourself.

Ansible Tower’s API

Ansible Tower’s API is fully browsable. You can navigate to your instance’s REST API by typing this into your browser: http://<Tower server name>/api/v2. Once there, you can click any of the listed links and view the current objects loaded for that particular attribute in Ansible Tower. Everything you can do in Ansible Tower's UI can be done from the API; you can also use it Continue reading

Momentum for Bioinspired GPU Computing at the Edge

Bioinspired computing is nothing new but with the rise in mainstream interest in machine learning, these architectures and software frameworks are seeing fresh light. This is prompting a new wave of young companies that are cropping up to provide hardware, software, and management tools—something that has also spurred a new era of thinking about AI problems.

We most often think of these innovations happening at the server and datacenter level but more algorithmic work is being done (to suit better embedded hardware) to deploy comprehensive models on mobile devices that allow for long-term learning on single instances of object recognition …

Team ISOC @ APRICOT 2018

Last month in Kathmandu, Nepal, 750 delegates participated in APRICOT 2018 – Asia-Pacific’s largest Internet conference. It was led by Internet Exchange Nepal (npIX) with support from several organizations including the Internet Society (ISOC) Nepal Chapter.

The Internet Society, through its Asia-Pacific Bureau, is a long-term partner of the APRICOT conferences, sponsoring a competitive fellowship programme, as part of the Internet Society’s mission to support capacity building in developing countries. Read more about our fellows at APRICOT 2018:

Meet the APRICOT 2018 Fellows

Team ISOC @ APRICOT 2018 comprised of staff from Regional Bureaus and Internet Technology. This included Andrei Robachevsky, Aftab Siddiqui, Rajnesh Singh, Salam Yamout, and myself.

In line with the Internet Society’s 2018 Action Plan, our core message at APRICOT 2018 was to strengthen the global Internet routing system and mitigate many of the risks facing the Internet’s core today. This includes route hijacking, traffic detouring, and address spoofing – which is a root cause of Distributed Denial of Service (DDOS) attacks. We promoted the Mutually Agreed Norms for Routing Security (MANRS), a set of recommendations addressing these risks, already adopted by some network operators.

Team ISOC took on a wide variety of roles Continue reading

IDG Contributor Network: How NFV and interconnection can help you think outside the ‘box’

Networking used to be all about specialized “boxes,” but that era is fading fast.  By a specialized box, I mean a piece of hardware that was built to perform an individual function. Physical firewalls, routers, servers, load balancers, etc., are all examples of these different boxes, and they are still everywhere. But new technology is seriously disrupting the old ways of doing things.Virtualization has made it possible to separate the software functionality of all those boxes from the specific appliance-type hardware in which it resides. Network functions virtualization (NFV) software can replicate an appliance’s function in a more cost-effective commodity server, which is easy to obtain and deploy and can hold the software for numerous functions at once. People like the improved simplicity, cost, agility and speed that comes with this change.To read this article in full, please click here

New in IPv6: Stable Random IPv6 Addresses on OpenBSD

The idea of generating random IPv6 addresses (so you cannot be tracked across multiple networks based on your MAC address) that stay stable within each subnet (so you don’t pollute everyone’s ND cache every time you open your iPad) is pretty old: RFC 7217 was published almost exactly four years ago.

Linux was quick to pick it up, OpenBSD got RFC 7127 support a few weeks ago. However, there’s an Easter egg in the OpenBSD patches that implement it: SLAAC on OpenBSD now works with any prefix length (not just /64).

BrandPost: SD-WAN: A Modern Approach to Connectivity for Digital Businesses

Digital transformation has crossed the chasm from visionary aspiration to practical implementation and in the process, it is disrupting technologies across the business landscape.As enterprises and governments transform their operations, many are finding their legacy wide area networks (WANs) cannot meet today’s digital-driven bandwidth demands. Rather than giving them a competitive edge and supporting business growth, their networks are stifling innovation and impeding flexibility.To address this challenge, software-defined WANs (SD-WANs) are emerging as a smart way to streamline connections among enterprise sites.Enterprise WANs are under pressure to keep pace with the cloud revolution, which plays a critical role in digital transformation. “Companies worldwide are aggressively consolidating their data centers, implementing new data models, and shifting development to agile, mobile-first, cloud-based models,” IDC Group Vice President and IT executive advisor Joseph Pucciarelli writes in the Winter 2018 Issue of CIO's Digital Magazine.To read this article in full, please click here

Using Travis CI (Continuous Integration) with GitHub

Hi ,

Am Planning to write a in detail usage of how we can leverage
Aws cloud - ansible - github - travis-(ci/cd) with in our networking 
deployment space. As of now, I will quickly author how you can 
leverage the usage of Travis CI in our 
experimental space. 

You can find more about Travis CI - Here - .org of travis will 
help to run Opensource Projects 

https://travis-ci.org/

I am using AWS cloud desktop to do the changes to the code, 
get it pushed to git-hub and then integrate everything 
if Travis CI passes the checks 

To let you know the workflow in a very simpler way 

-> You write any code or config related to networks on AWS cloud 
desktop
-> push the code into git-hub in a branch later to be integrated 
into Master Branch
-> Setup Travis to automatically run some pre-defined tests 
-> If all successful, we will merge the code into our master branch 

-> Lets write a very basic code in a branch and push to git-hub 

 




The github page has been integrated with Travis-CI 

 




Travis CI peforms the required checks, here it just 
checks for syntax, obvious this can be exetended  Continue reading
