Using JavaScript to interact with the REST Query API
We’re very excited to announce that our REST Query API is now available
[/2016/05/now-available-rest-query-api/]. With this API, you can:
* make it easy to remotely query your log data
* easily integrate Logentries with third party solutions, external systems and
internal tools
* allow users and systems to query their log data programmatically over our
REST API
In this article, I will show how you can quickly interact with the Query API by

How to: Send SMS messages to Logentries in under 5 minutes (maybe 10)
The “Internet Of Things” continues to be talked about a lot with an increasing
number of devices now containing some sort of smart functionality which can be
interacted with. Here’s a great article about end-to-end IoT monitoring
[/2014/12/end-to-end-iot-monitoring-with-log-data/] by colleague David Tracey.
However, not all IoT devices can be in locations with WiFi or 3/4G coverage, so
they can not easily (or at all) send or receive data over the internet, and
instead rely on standard cellula

What Security Operations Teams Can Learn From Modern Productivity Software
Between your devices, how many apps do you have?The answer for many is
dozens, if not hundreds. And many are designed to help us be more efficient: to
keep track of growing to do lists, manage complex work tasks, or streamline
communication with teams. The trouble is, many of these apps don’t talk to each
other very neatly, efficiently, or at all.
So it’s no wonder that when the app orchestration solution IFTTT was launched,

The Dangers Of Linear Thinking and Why Security Analysts Should Defend in Graphs
One of my favorite tweets-turned-into blogs of last year was one by Microsoft
security’s John Lambert: “Defenders think in lists, attackers think in graphs.

How to Compare Google Compute Engine & AWS EC2
Which Virtual Machine is Best: Google’s Compute Engine or Amazon’s EC2? It
Depends.
The Internet might seem like a Wild West of chaotic connections because it often
is. Companies like Google and Amazon have
been managing to create order out of the chaos for years by understanding the
nature of the World Wide Web. Within the last 10 years, Google and Amazon have
leveraged that understanding into a robust suite of product offerings in the
field of Infrastructure-as-a- Service, or IaaS.

The best security operation centers (SOCs)
[https://www.rapid7.com/fundamentals/security-operations-center/] are built on
efficiency and speed-to-response. But if you’ve ever worked in a SOC or on a
security team, you know it’s tough to get your security systems, tools and teams
to integrate in a way that streamlines detection, response, and remediation.
One of the most tedious tasks of all is cobbling together alert details to
assess if a security event is a real threat, along with correlating

Client Side Logging In Javascript
Developers are writing Javascript applications of increasing complexity designed
to run in web browsers, on desktops, and on servers. Javascript applications
have reached a level of maturity that means they are running important business
operations. They must be more maintainable and supportable now that they have
achieved this level of responsibility in the enterprise. Javascript
applications should be expected to provide the same information for support and

Do You Still Email Yourself from Your Code? How to Stop the Madness
A few years back now, I took on an assignment to help a company modernize a
series of legacy .NET applications. One of these did some back office
processing. A vendor would stick some files on a shared drive, and a windows
scheduled task would invoke this bit of code to parse the file, apply a whole
slew of business rules to its contents, and then update the appropriate internal
systems. The details are both proprietary and uninteresting, so I will spare
you those.

The 4 Steps for Creating a Log Enabled Marketing Campaign
Typically, most logging activity in the online world is concerned with
collecting information about an enterprise’s digital infrastructure. Machine
logs, application logs, network logs, database logs, access logs are a few
examples of such activity. However, as marketing campaigns become more
integrated into application activity, using log data to monitor and to measure
the effectiveness of a campaign is a viable extension of an enterprise’s current
logging activity.
But, we need to beware.

Regular Expressions
When it comes to searching unstructured data, regular expressions are a very
useful and powerful tool. The power provided by popular regular expression
libraries does come with a significant performance cost in some cases though,
both when compiling regular expressions into automata (state explosion problem
when determinising automata) and when using these automata to match input. These
constraints are usually acceptable for individuals ne

A point of @Contention- cache coherence on the JVM
Java 8’s major changes- lexical closures, the stream API, e.t.c have
overshadowed a slew of little gems, one of which I only discovered the other

False Sharing
Chances are you’re reading this on a device with more than one CPU. There’s
therefore also quite a good chance the you have more than one thread of
execution running at the exact same time. There’s an equally good chance that

Deciphering MySQL Logs: The What, Why, and How
Logs are one of the best ways to understand what a server is doing. Thankfully,
MySQL has no shortage of log activity to assist a DBA in its maintenance. It
writes out its activity to 5 different logs. This post will take a look at the
existing MySQL logs and how they assist the administrator.
* On Windows, - The log is written to the data directory with a .err extension
even if not explicitly enabled.
* Errors are automatically written to the Event Log. This behavior is standard
