IntroductionFaultsException Management Best PracticesIntroductionThis article focuses on practical approaches to exception management that will reduce development and troubleshooting time. The foundation for good exception management is the Dependency Injection (DI) design pattern. The techniques in this article rely on that pattern, as discussed in the following article: www.microsoft.com. If you rely on DI to manage exceptions, SOAP faults, and validation, the developers on your team will not have to incorporate complex exception logic in their service operations. This is because, when implemented correctly, the service code will have little need for try…catch blocks. (An exception to this rule is data access code. In this case, you should capture all of the parameters in stored procs, SQL statements, and so on).The following figure illustrates how, with DI, validation and exception management for the MyService implementation are performed before the service operation is called.The following code is an example of how complex the code for exception management and validation can be without DI.
and libraries out there, and most developers use one or more of them every day. A few examples off the top of my head for the .Net developers: log4net, nLog, elmah, and the Enterprise Library Logging Application Block. They are simple equal error rate and easy to use, and work great for developers debugging code. It’s still just not enough comprehensive error rate testing though. Have you ever had to work with your log files once your application left development? If so, you quickly run into a few pain points:

There’s a lot more data You have to get access to the data It’s spread across multiple servers A specific operation may be spread across service boundaries – so even more logs to dig through It’s flat and hard to query https://msdn.microsoft.com/en-us/library/hh323726(v=vs.100).aspx – even if you do put it in SQL, you are going to have to do a lot of indexing to make it usable It’s hard to read You generally don’t have any context of the user, etc You probably lack some details that would be helpful (you mean “log.Info(‘In the method’)” isn’t helpful???) Managing log file rotation and retention Additionally, you have all this rich data about your app that is being generated and you simply aren’t proactively putting it to work. It’s http://stackify.com/smarter-errors-logs-putting-data-work-2/ time to get serious. Once you’re working on an application that is not in the development environment, logging messages (including exceptions) are usually your only lifeline to quickly discovering why something in your app isn’t working correctly. Sure, APM tools can alert you to memory leaks and performance bottlenecks, but generally lack enough detail to help you solve a specific problem, i.e. (why can’t this user log in, or why isn’t this record processing?). At Stackify, we’ve built a “culture of logging” which set out to accomplish these goals: Log all the things. Log as much as we possibly can, to always have relevant, contextual logs that don’t add overhead. Work Smarter, not Harder. Consolidate and aggregate all of our logging to a central location, available to all devs, and easy to distill. Also, to find new ways for our logging and exception data to help us proactively improve our product. In this post, we’ll explore these concepts, and share what we’ve done to address it, much of which has become a part of Stackify’s Smart Error & Log Management (SmartELM) product. Log all the things. I’ve worked in a lot of shops where log messages looked like this: I’ll give the developer credit: at least they are using a try / catch and handling the exception. The exception will likely have a stack trace so I know where it came from, but no other context. More on this later. Sometimes, they even do some proactive logging, like this: B
is the definition of a medication error? What are the “ten key elements” of the medication-use system? Won’t medication errors be prevented if nurses just follow the “Five Rights?” What are "high-alert" http://www.ismp.org/faq.asp medications? What abbreviations are dangerous? Are these evidence based? What drug names are frequently confused? How should tall man lettering be applied to differentiate look-alike/sound-alike drug names? What is confirmation bias? How do I do an independent double check? How can I measure culture? Should a healthcare practitioner be disciplined for being involved in an error? How can I assess risk? What is the difference error rate between high-leverage and low-leverage safety strategies? What is an FMEA, and how can I use it? How do I join ISMP? What ISMP resources are available for consumers? Why are standard concentrations safer than using the Rule of 6 for pediatric drips? What tools does ISMP have to satisfy regulatory or insurance network inclusion requirements for community pharmacies to demonstrate participation and knowledge in medication best practice error safe practices? Is there a way to get involved with ISMP as a student? Does ISMP have a nationally registered student-organization? 1. What is the national medication error rate? What standards are available for benchmarking? A national or other regional medication error rate does not exist. It is not possible to establish a national medication error rate or set a benchmark for medication error rates. Each hospital or organization is different. The rates that are tracked are a measure of the number of reports at a given institution not the actual number of events or the quality of the care given. Most systems for measuring medication errors rely on voluntary reporting of errors and near-miss events. Studies have shown that even in good systems, voluntary reporting only captures the "tip of the iceberg." For this reason, counting reported errors yields limited information about how safe a medication-use process actually is. It is very possible that an institution with a good reporting system, and thus what appears to be a high error "rate," may have a safer system.
