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

when he responded by saying, “Slack and Logentries, cool! Yep everyone is doing

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

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!

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.

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

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

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

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

JSON Formatting of Windows Events: It's Hot!
