During Christmas Eve, many Netflix lovers planned to stream some  holiday movies and watch them together with their loved ones. Unfortunatley they were disappointed because the service was unavailable.


Unlikein the past, today millions of businesses that are providing online services depends on companies like Amazon to provide the critical infrastructure needed to provide online services. In the above situation because of an outage at Amazon’s end many of the Netflix customers were left stranded on Christmas Eve.


While Amazon publicly apologized , the Netflix lovers blamed Netflix for jeopardizing their holiday experience.


As in the case above the application performance can’t be looked at in isolation of underlining application infrastructure availability.


DevOps and Cloud impact


Armed with agile development and DevOps, modern IT departments are rolling out new changes to their IT applications at a rapid pace. It’s not uncommon for IT Ops teams to roll out changes to their business applications on a daily basis. These software are deployed on distributed IT Infrastructure spanning across public, private and hybrid clouds located across the world.


The combination of “rapid change” in applications introduced by DevOps and “distributed” application infrastructure hosted on cloud introduces significant risk to modern IT applications performance.


In the era of DevOps and cloud computing, the ability to avoid downtime and monitor your application infrastructure performance in real time can be a real competitive edge.


Three traditional monitoring approaches


Most traditional IT monitoring tools fail to deliver deep insight into your rapidly changing application infrastructure in real time so that you are able to pinpoint an issue before it impacts your business.

Here are the shortcomings of the top three traditional approaches to monitor performance of a dynamic IT environment in real time:


1.    Event consolidation with central dashboards — While this helps you reduce the chatter, it introduces a significant lag in the time an issue is first detected by operators, when it is assigned to appropriate expert team and when it is finally resolved

2.    Remote monitoring — This monitors most of your IT infrastructure in a non-intrusive way, however it lacks the details needed to see any impact at a granular level

3.    Log monitoring — It is a much faster way to understand the issue, but it is still a reactive approach


 How to drill into details down to the second


The best fit for such dynamic environment is a very light-weight instrumentation like HP Compute Sensor, which provides granular details of your application infrastructure every second and can be easily deployed in a modern cloud environment.


Also such instrumentation should be integrated with a hybrid cloud monitoring solution like HP Virtual Performance Viewer (vPV), in order to get the big picture of your IT Datacenter performance on a single dashboard.


HP Compute Sensor, with its per-second system performance data streaming, is your magnifying glass to uncover what happened with your server one second after you rolled out your new application.



With 1-second delay streaming data collection, the DevOps team can immediately visualize the impact of their new application rollout on IT Infrastructure. They can also identify the resource-greedy application process that is slowing down application performance and tune their designs better for the next rollout.


At the same time, the datacenter admin can visualize the new applications rolled out on this VM and understand new applications impact on infrastructure resources. They can further optimize the resource allocation to this dynamic VM by visualizing the current performance in real time and checking the key system events.


This way, the DevOps and IT Ops team can work together to rapidly introduce changes to business applications across the hybrid cloud infrastructure without impacting the uptime.

Collect and analyze your system information every second. HP Compute sensor is less than 5 MB in size, installs in just 10 seconds and is bundled with the free download of vPV 1.2,
