Using DevOps to Troubleshoot Performance Issues | @DevOpsSummit [#DevOps]

TroubleShooting with VisualVM

In my  previous article, I had introduced how DevOps can play a role in JVM troubleshooting. In this series, I would like to share a case study that we encountered in our organization and how we isolated the issue before engaging the right team to fix it.

One of our customers upgraded to the latest application release from previous release and noticed a significant performance degradation in the throughput. As a first step, we confirmed the customer claim by reproducing the reported issue in our environment. Having a local reproduction environment opened up opportunities to try out multiple things in narrowing down the issue. After a preliminary analysis, we had concluded the area or component that is contributing to the observed behavior. A workaround to overcome the issue was identified and the same was employing a command-line parameter, which will take a different execution path. The provided recommendation was tested in our local reproduction environment with success and this gave us the confidence that the issue can be overcome with the current recommendation.

On further analysis, we engaged the appropriate tool to determine the percentage of time consumed and captured the snapshots with the latest release and the previous release where issue was not noticed. This level of analysis revealed the exact area where more time was spent. Once these snapshots were shared with the development team, the development team task was much easier as the area of code was already narrowed down for fixing. This way we isolated the issue and helped customer to overcome the problem.

The use-case scenario was that of retrieving data from the CACHE using CouchBase as Caching Solution. However, there were multiple other components present in the stack.

Poor data quality and analytics drive down business value. In fact, Gartner estimated that the average financial impact of poor data quality on organizations is $9.7 million per year. But bad data is much more than a cost center. By eroding trust in information, analytics and the business decisions based on these, it is a serious impediment to digital transformation.

When talking IoT we often focus on the devices, the sensors, the hardware itself. The new smart appliances, the new smart or self-driving cars (which are amalgamations of many ‘things'). When we are looking at the world of IoT, we should take a step back, look at the big picture. What value are these devices providing. IoT is not about the devices, its about the data consumed and generated. The devices are tools, mechanisms, conduits. This paper discusses the considerations when dealing with the...

IoT is rapidly becoming mainstream as more and more investments are made into the platforms and technology. As this movement continues to expand and gain momentum it creates a massive wall of noise that can be difficult to sift through. Unfortunately, this inevitably makes IoT less approachable for people to get started with and can hamper efforts to integrate this key technology into your own portfolio. There are so many connected products already in place today with many hundreds more on the h...

Disruption, Innovation, Artificial Intelligence and Machine Learning, Leadership and Management hear these words all day every day... lofty goals but how do we make it real? Add to that, that simply put, people don't like change. But what if we could implement and utilize these enterprise tools in a fast and "Non-Disruptive" way, enabling us to glean insights about our business, identify and reduce exposure, risk and liability, and secure business continuity?
