Acceptance Tests In Practice - Behavior Driven Development

What is Acceptance Testing? "Acceptance testing is a test conducted to determine if the requirements of a specification or contract are met.” (Wikipedia definition [http://en.wikipedia.org/wiki/Acceptance_testing]) In simple words, Acceptance tests check if the software that we have built matches the requirements that were provided. The Magical Black Box Acceptance testing is usually performed using “black box [http://en.wikipedia.org/wiki/Black_box]” testing method. The tester of the system k

The Role of Logging in ChatOps

What is ChatOps [https://www.rapid7.com/fundamentals/chatops/] you might ask? Well, if you are like me, you and your team may be already be doing it and you don’t even know it. On a recent visit to San Francisco I was telling one of our tech partners about our new Slack integration [https://logentries.com/logentries-slack-integration-powers-faster-collaboration-real-time-resolution-dev-ops/] when he responded by saying, “Slack and Logentries, cool! Yep everyone is doing ChatOps these days…”

Infographic: Top 4 Log Management Challenges

At Logentries [http://logentries.com] we chat to new users everyday who are looking for an improved solution for centralizing and analyzing their log data. They have often tried rolling their own solution, have previously gone the open source route, or are using an “old school” logging technology. But, what we find across new users, regardless of how they are managing their log data, are some common challenges that have historically made log management [https://www.rapid7.com/fundamentals/what-

Unit testing with Karma and Jasmine for AngularJS

So you’ve started to build applications with AngularJS; or, maybe you’ve done unit testing before but haven’t used it with AngularJS; or, maybe it’s all new to you, but either way this article should help to orient you to the value of using Karma with Jasmine and offer some tips on displaying functionalities of Angular JS. Let’s get started! My app is small it doesn’t need any tests, right? [https://logentries.com/centralize-log-data/] Wrong! A small app can have errors and it’s bad practic

Dynamite Plots, Logs, & the Joy In Knowing

I saw this online and chuckled. I believe it was Mark Twain that said, “Humor is the good natured side of truth.” Well, in my humble opinion, humor can be used as the genesis for interesting blog posts. So, you may be wondering, what do Dynamite Plots, logs and the joy of knowledge have to do with each other? Well, if you have a few minutes, I’ll try to make the link. For me, the humor of the cartoon above is rooted in multiple areas, but most of all in the idea that the data inherently has

Connected QA: Selenium + Log Analysis

Does the idea of adding Quality Assurance (QA) test runs to your log analysis platform sound strange? It’s actually not! The value in adding QA test runs goes beyond helping the QA team; it helps the entire development shop as they move to a DevOps framework. [/content/images/le-img/2014/12/Using-Log-Analyis-for-Selenium-QA-Testing.png] I talk a lot about the integrated development environment and going beyond ad-hoc tool selection to a more deliberate and holistic approach. This also means br

Is Server Monitoring Dead?

Once upon a time one of the first pieces of software you installed on your infrastructure was a server monitoring tool. This was the control panel through which you could view how effectively your infrastructure was being used, akin to the speedometer and temperature gauges on your car, or the dashboard of dials in an airplane’s cockpit. Server monitoring tools usually work by capturing resource usage information from your OS performance API or performance counters (e.g. via proc stats on linu

End-to-End IoT Monitoring with Log Data

A recent blog [/2014/11/what-is-the-role-of-logging-in-the-internet-of-things] explored the importance of logging in general in terms of IoT devices. It also cited predictions that a huge number (50 billion) of IoT devices are expected to exist by 2020. While Machine to Machine(M2M) communication is a related area, the IoT is all about extending the Internet to systems and even low power devices. While there is uncertainty about the exact nature of how these devices will be networked and how th

Best Practices for Cloud Logging, Security, & Data Protection

When we first founded Logentries in 2010 a lot of people thought Viliam Holub (co-founder, CTO, and the brain behind processing billions and billions of log events in real time [https://logentries.com/real-time-log-stream-analytics/]) and I were crazy. The common response was: “People are not going to send their logs to the cloud… logs might contain very sensitive data…” Like typical stubborn founders we persevered in spite of this, and today we have more than 35,000 users across 100 countries

Community Packs for AWS: Out of the Box Dashboards, Alerts, & Queries

We recently released Logentries Community Packs [https://logentries.com/logentries-launches-shareable-community-driven-log-analytics/] , dynamic JSON files that (when uploaded into Logentries [http://logentries.com] ) automatically create Saved queries, Dashboards and Alerts. The true power of these packs is that anyone can create, modify and share them. We called them Community Packs because we want to offer different Communities a “pack” of log analysis features customized for their specifi

ES6: Javascript in Harmony: An Overview of New Language Features

ECMAScript 6 brings powerful new capabilities and some tasty syntactical sugar to the ubiquitous Javascript language, as it continues to grab an ever increasing slice of developer mindshare. Now that the ES6 feature set is frozen and just minor refinements will be made over the coming months, much of this new functionality has already landed in modern browsers, and will continue to roll out with each new browser update. For the impatient, there are also now several excellent precompile / polyf

How to Implement JSON Formatting of IIS for Analytics and Troubleshooting

Previously, we wrote about setting up a Windows environment [/2014/11/json-formatting-of-windows-events-its-hot/] to log JSON formatted logs using our Windows Agent or our DataHub.  Now we’ll tackle IIS [http://www.iis.net]. IIS, like Windows, has a unique log format that makes it difficult to read, parse, and garner useful information.  The log is a flat file that has a line-per-web hit; similar to Apache or Nginx. But, it’s not as easy to format intoJSON as Apache and Nginix [/2014/08/json-lo

For the Love of Code: Why We Use JSHint for Static Code Analysis

As developers, we all strive for clean, readable, and easy to refactor code; but, unfortunately, this doesn’t always happen. No matter how great a developer you are, or what language you’re coding in; problems caused by bugs inevitably spring up like weeds in the grass. These problems are exasperated by poorly organized and poorly written code. Once quality starts to drop, even the cleanest high-quality code in your project begins to be affected, until you’re left with a jumbled mess of (and ha
