IOT made real - Using TI SensorTag data with Logentries and NodeRed

Learn how to send IoT Data from the TI CC 2650 SensorTag to Logentries (using Node-Red). This is the first of a series of IoT blogs that show you how easy it can be to integrate a range of real sensor devices with Logentries and how to use the data from those devices once it is in Logentries. This follows the earlier blog [/2014/12/end-to-end-iot-monitoring-with-log-data/] showing why a centralised logging service would be useful for IoT developers and users. This series of blogs will show ju

Considering the Explosive Growth of Log Analytics

You’d have to be living in a cave to not know that the practice of log analytics in corporate IT has grown dramatically in the last 10 years. This explosion in logging activities over the recent years is due to two factors, the maturing of log technology and the expanded application of logging to new information domains such as tracking user behavior, tracking page views, and tracking API interaction, to name a few such activities. As logging technology matures, the price goes down. Getting a

Analyzing ELB Log Data

Thanks to some slick work from our engineering team, we have recently released a lightweight python script that will allow you to pull your Elastic Load Balancer logs from S3 into Logentries. In this implementation, we use AWS Lambda and leverage the S3 trigger, so the script only runs when needed. The full documentation is available here: https://logentries.com/doc/s3-ingestion-with-lambda/ [https://logentries.com/doc/s3-ingestion-with-lambda/?utm_source=134&utm_medium=blog&utm_campaign=12

Introducing a Buildbot status plugin for pushing status updates to Logentries

Buildbot is a framework for building continuous deployment and integration systems, it is highly flexible and is written in python. It is also a mature system which a number of large projects use e.g. Mozilla, Chromium, Python – see trac.buildbot.net/wiki/SuccessStories [http://trac.buildbot.net/wiki/SuccessStories] To send build status information — specifically Start, Success and Failure states from Buildbot to Logentries — start by generating a log token from Logentries.

How to Log Messages from Slack

We recently added support for unedited HTTP logging in Logentries. This means you can send us log data via HTTPS drain (from heroku), or via any webhook you want. One webhook that we’ve been looking to log for a while is Slack [https://logentries.com/resources/#plug-ins]. People are always chatting away on Slack, and this data might be useful some day. You can send the data into Logentries however you want, and then worry about what to do it when you actually need it! First, you’ll need to

Logentries recognized by Docker as Ecosystem Technology Partner for Logging

Since last year, we’ve anticipated the impact of Docker [/2014/05/musings-on-the-future-of-docker/] and have been building integrations – first as experiments [/2014/03/how-to-run-rsyslog-in-a-docker-container-for-logging/] and later as full-blown solutions [/2015/07/an-all-inclusive-log-monitoring-container-for-docker/]. It’s therefore with great pleasure that we’re announcing our recognition by Docker as an Ecosystem Technology Partner for Logging. Why Monitor Docker Logs? Most teams that

Analysing Hystrix metrics with Logentries

We’ve been using Hystrix [http://techblog.netflix.com/2012/11/hystrix.html] in production here at Logentries for over a year now [shameless plug: I briefly talked about this [https://speakerdeck.com/m0wfo/clojure-ireland-talk-june-2015] at a Clojure Ireland meetup recently :)] and have found it useful not only for bulkheading [http://martinfowler.com/bliki/CircuitBreaker.html] requests, but for getting fine-grained metrics for internal API calls. Netflix has also open-sourced a funky dashbo

Introducing LEQL: percentile() & median

While analyzing data, it’s important to use a variety of calculations to ensure you get the best insights. Today, we’re excited to announce the availability of our two newest LEQL functions: percentile() and median. percentile() allows you to calculate the number below which a given percentage of your log entries fall. To use a real world example, what was the longest response time for 95% of my application’s users? Similarly, median (or the 50th Percentile) gives you the middle number in a s

Unleash the power of node.js for Shell Scripting (Part 2)

Ready for our first proper node.js Script! In a previous post [/2015/10/20/unleash-the-power-of-node-js-for-shell-scripting-part-1/], we learned about some tools that helped us create a script in node.js. It is now time to put this into practice by implementing a script that connects to a few online newspapers, searches in the news for specific keywords and returns those articles. Our new script will need to accept the following parameters: * A file with the list of newspapers (one URL per li

Java 8: A quick introduction to Parallelism and the Spliterator

Introduction With the release of Java 8 a number of new language features were introduced [1] . These included lambda functions, streams and completable futures. Colleagues of mine have already reviewed these features in previous articles on this blog, which I recommend reading as part of this topic [2] [3]. In this article I will touch on an aspect of the Java 8 release that relates to the push towards exploiting parallelism, in the context of the existing Collections Framework – specifically

Unleash the power of node.js for Shell Scripting (Part 1)

Setting Up Running a Node Script We are going to talk about creating shell scripts with node.js. The first thing that you need to do is install node.js. You can get the installers from https://nodejs.org/en/download/, or use your favorite package manager. Let’s go straight in and write our first script. The first thing to do is to create a file called script.js with the following code: console.log('hello world') We can now execute this script by running the following command in our shell:
