Logging OwnTracks to Logentries
A previous blog
[/2016/10/07/logging-mosquitto-server-logs-from-raspberry-pi-to-logentries/]
showed how MQTT logs can be sent to Logentries for storage, analysis and how
those logs can be to alert on potential MQTT security threats, as well as to
store and visualize sensor data. This blog follows that by showing how to build
a fully connected IoT system composed of the OwnTracks iOS app as an MQTT
publisher, a Raspberry Pi with Mosquitto embedded as an MQTT messaging broker
and Logentries as

Logging Mosquitto Server logs (from Raspberry Pi) to Logentries
The Internet is evolving and part of this is the emerging Internet of Things
(IoT). IoT allows us to use the Internet to seamlessly connect the cyberspace
and real world using physical sensors at huge scale, allowing us to gather and
analyze the data across many domains. It is estimated that there will be 20
billion Things connected to the Internet by 2020, generating an enormous amount
of data.

Moving away from MVC
In of all my years as a software engineer, trying new libraries, frameworks and
paradigms has been such a pleasure especially in web development. Even before
the well known javascript libraries, web development was based on backend apps
which render heavy html code within css and some js code. Frameworks such as
spring, .NET MVC, django and rails helped us with abstractions and predone tasks
increasing development speed and quality (reuse principles). But, it was not
enough. Apps were getting

Hashing Infrastructures
Engineers in fast moving, medium to large scale infrastructures in the cloud are
often faced with the challenge of bringing up systems in a repeatable, fast and
scalable way. There are currently tools which aid engineers in accomplishing
this task e.g. Convection, Terraform, Saltstack, Chef, Ansible, Docker. Once the
system is brought up there is a maintenance challenge of continually deploying
and destroying the resources. What if we can hash the inputs for describing an
infrastructure, where

4 Potential Security Issues Raised By Pokémon Go
Pokémon Go is a phenomenon. The game is objectively a success and has been
breaking mobile gaming records almost weekly. The game’s current success is
without being open in some significant markets and it shows no signs of slowing.
It is important to remind players to take measures to protect your company’s
interests when playing.
Pokémon Go is an Augmented Reality game. Players see the game’s fictional world
on top of everyday reality. Augmented Reality manifests in several ways: from

Integrating Logentries with OpsGenie: 3 Easy Steps
Real-time alerts [https://logentries.com/product/alerting-and-reporting/] are
only as good as their ability to successfully reach their intended audience. If
an alert recipient only checks email once every several hours, email alerts
would not be well suited for real-time notification.
It’s for this reason that Logentries makes it easy to integrate with popular 3rd
party tools that DevOps professionals are already using, including Slack

Exporting Logentries data with Leexportpy
Leexportpy, the Logentries utility that exports your log data to 3rd parties,
has built-in support for various services such as Kafka, Geckoboard and Hosted
Graphite. Without any modification to the current code, you can use these
services to extract your Logentries data.
To begin, make sure your read-write or read-only API key is correctly placed in
the LE section of your configuration file as shown below. Also make sure you
have read the first blog post of this series.

What exactly is an Event-loop?
“The price of reliability is the pursuit of the utmost simplicity” – C.A.R Hoare
Rather than doing another all-out performance post, I’ll look at some aspects of
asynchronous I/O today instead: what it is at a high level, what it isn’t and
why you would use it.
There aren’t many aspects of programming today that are as saturated with
buzzwords and misinformation as asynchronous IO and some of the frameworks which
build on top of this. If you work with server code which has to handle a

Introduction to the Logentries Command Line Interface
The Logentries Command Line Interface (CLI) allows you to both manage and use
your Logentries service right from the command line. The CLI is built on the
Logentries REST APIs [https://docs.logentries.com/docs/rest-api] and provides a
tool to interact directly with the Logentries service outside of the UI. It is
in beta and currently supports retrieving log events, and performing queries and
calculations on log events using our powerful querying language LEQL

Using Logentries With Angular v1.5
The post assumes at least a basic knowledge of Angular. Angular is a very
opinionated framework so make sure you have some experience with Angular before
following the instructions presented below.
Logentries can integrate into whatever Javascript framework you want to use.

Backup Log Checks and What They Can Tell You
There is simply no substitute for a recent, accurate backup when it comes to
recovering from file or system damage or outages. But that backup must be
complete and error-free to make a full recovery possible. That’s why inspecting
log files from backups is a critical and important step in verifying their
accuracy or coverage, and a necessary check before performing a restore that
converts any backup image or files into production status.

Keep Your Code Clean while Logging
In my consultancy practice, one of the things that I do most frequently is help
teams write so-called “clean code.” Usually, this orients around test-driven
development (TDD) and writing code that is easily maintained via regression
tests and risk-free refactoring. Teams want to understand how to do this, and
how to do it in their production code (as opposed to in some kind of toy “let’s
build a calculator” exercise).
One of the most prominent, early sticking points that rears its head tend
