Don’t Trust Your Log Files: How and Why to Monitor All Exceptions
I would say that only one out of a million exceptions thrown in an application actually makes it to a log file - unless you run your application in verbose logging mode - Do you agree? No? Here is why I think that is: because most exceptions are handled by your code or by the frameworks your app uses. Here is a chart from an enterprise application showing that there are about 4000x more custom application exception objects thrown than important log messages written:
4000 times more Exceptions than log messages: Can they be ignored? What's their impact?
Why worry about these exceptions that nobody cares to write to a log file? Two reasons:
- They are typically thrown for a good reason and therefore indicate a problem, e.g., configuration issues in frameworks or runtime problems
- Every Exception object is a potential performance problem because it means the JVM needs to allocate memory, get the stack trace and dispose the object soon after
Reason #1: Configuration Problems
The following shows a transaction where the method getImagePath makes a web service call to a back-end server using HttpClient. getImagePath uses an HTTP Endpoint URL. The Web Service however only supports HTTPS (SSL). The web service call therefore fails with an SSLException. getImagePath retries three times until it gives up and just returns a default value to the caller. No log entry written, no exception thrown to the caller, everything seems okay to the outside world even though we have a severe impact on an end user who is waiting longer than necessary for an image that he doesn't get to see:
Exceptions are highlighting configuration problems (wrong URL) but the calling method is not doing anything with that information
- End Users: This code is executed for every user that executes this request and none of them will get the correct image path. Additionally, the user is waiting on it for several seconds. We all know what users will do if they have to wait too long.
- Business: If your app delivers dynamic user-specific content, e.g., recommendations for that user, you need to ensure that no configuration problem causes your app to deliver incorrect content. As business owner you want to get alerted when a problem in the app causes incorrect responses to your users.
- Operations: When users complain, there is no documented evidence of a problem (nothing in a log file). Make sure to monitor outgoing web requests and the status of these calls as this helps you to identify if you have requests that start failing or not delivering what they are supposed to deliver.
- Developers: Everything probably worked well when they tested this web service in their own environment where they used a dummy or mocked web service endpoint. Make sure to add log for these situations and let Operations know how to configure these endpoints.

According to Forrester Research, every business will become either a digital predator or digital prey by 2020. To avoid demise, organizations must rapidly create new sources of value in their end-to-end customer experiences. True digital predators also must break down information and process silos and extend digital transformation initiatives to empower employees with the digital resources needed to win, serve, and retain customers.

We're entering the post-smartphone era, where wearable gadgets from watches and fitness bands to glasses and health aids will power the next technological revolution. With mass adoption of wearable devices comes a new data ecosystem that must be protected. Wearables open new pathways that facilitate the tracking, sharing and storing of consumers’ personal health, location and daily activity data. Consumers have some idea of the data these devices capture, but most don’t realize how revealing and...

IoT solutions exploit operational data generated by Internet-connected smart “things” for the purpose of gaining operational insight and producing “better outcomes” (for example, create new business models, eliminate unscheduled maintenance, etc.). The explosive proliferation of IoT solutions will result in an exponential growth in the volume of IoT data, precipitating significant Information Governance issues: who owns the IoT data, what are the rights/duties of IoT solutions adopters towards t...

Whether your IoT service is connecting cars, homes, appliances, wearable, cameras or other devices, one question hangs in the balance – how do you actually make money from this service? The ability to turn your IoT service into profit requires the ability to create a monetization strategy that is flexible, scalable and working for you in real-time. It must be a transparent, smoothly implemented strategy that all stakeholders – from customers to the board – will be able to understand and comprehe...

Complete Internet of Things (IoT) embedded device security is not just about the device but involves the entire product’s identity, data and control integrity, and services traversing the cloud. A device can no longer be looked at as an island; it is a part of a system. In fact, given the cross-domain interactions enabled by IoT it could be a part of many systems. Also, depending on where the device is deployed, for example, in the office building versus a factory floor or oil field, security ha...

In this strange new world where more and more power is drawn from business technology, companies are effectively straddling two paths on the road to innovation and transformation into digital enterprises. The first path is the heritage trail – with “legacy” technology forming the background. Here, extant technologies are transformed by core IT teams to provide more API-driven approaches. Legacy systems can restrict companies that are transitioning into digital enterprises. To truly become a lead...

"Once customers get a year into their IoT deployments, they start to realize that they may have been shortsighted in the ways they built out their deployment and the key thing I see a lot of people looking at is - how can I take equipment data, pull it back in an IoT solution and show it in a dashboard," stated Dave McCarthy, Director of Products at Bsquare Corporation, in this SYS-CON.tv interview at @ThingsExpo, held November 1-3, 2016, at the Santa Clara Convention Center in Santa Clara, CA.

What happens when the different parts of a vehicle become smarter than the vehicle itself? As we move toward the era of smart everything, hundreds of entities in a vehicle that communicate with each other, the vehicle and external systems create a need for identity orchestration so that all entities work as a conglomerate. Much like an orchestra without a conductor, without the ability to secure, control, and connect the link between a vehicle’s head unit, devices, and systems and to manage the ...

The Internet of Things (IoT) promises to simplify and streamline our lives by automating routine tasks that distract us from our goals. This promise is based on the ubiquitous deployment of smart, connected devices that link everything from industrial control systems to automobiles to refrigerators. Unfortunately, comparatively few of the devices currently deployed have been developed with an eye toward security, and as the DDoS attacks of late October 2016 have demonstrated, this oversight can ...
