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

Integrating Logentries with OpsGenie: 3 Easy Steps

Real-time alerts [] 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. [/2016/07/introductio

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 nontri

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 [] 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.  Previously, we examined adding Logentries to a React application [/2016/05/integrating-the-logentries-javascript-library-with-react/].  This post will illustrate how to add Logentries to your Angular v1 application using

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. Your backup logs [

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
