How To: Send Logentries Alerts to BigPanda

Working in customer support we are usually the first to receive feature requests, integration requests or recommendations. We would then relay this to our product team. But we often get requests that we can tackle ourselves whether this may be small coding tasks or account changes. So when we heard a user wanted to be able to forward their Logentries alerts to BigPanda.io, we made that happen. When any issues occur, time to resolution matters. Because Logentries streams your log data in real-

Nagios Series: DNS Resiliency

Synopsis: Host operating system resolver libraries are not very good at dealing with an unreachable nameserver. Even if you specify multiple nameservers in resolv.conf and one of them goes down you will experience a period where connections will not be made because resolution is not known. There are a number of resolver tuning options but even reducing the timeout to 1 second there will result in a delay. This affects nearly all unix-like operating systems including GNU/Linux.

Raspberry Pi, Logs and IoT - Sending Pi Log and Sensor data to Logentries

In the previous blog post [/2016/02/iot-made-real-using-ti-sensortag-data-with-logentries/] we learned how to send IoT data from the TI CC 2650 SensorTag to Logentries using Node-Red and directly using Linux. This Blog will show how to send data from a Raspberry Pi device to Logentries [https://logentries.com/centralize-log-data-automatically/?le_trial=raspberry_pi-logentries_blog-post_cta-create_trial&utm_campaign=raspberry_pi&utm_source=logentries_blog&utm_medium=post_cta&utm_content=create_

A Query Language for Your Logs

Application logging is the software world’s version of archeology. At runtime, your application lives in a rich, colorful, 3-dimensional world of flowing aqueducts, packed coliseums, and bustling streets.   There’s more going on than can possibly be captured. When you’re trying to reproduce and correct a reported issue, you play archeologist. The vibrant, live world is gone, and you’re left to piece reality back together using only decorated pots, spearheads, and fragments of frescoes. In oth

The SOC of the Future: Predictions from the Front Line

There is no perfect security operations center, and I say that having worked at one in the past [/2016/05/03/6-lessons-i-learned-from-working-in-a-soc/] and collaborated with many others since then. That said, as an industry, we are always evolving and improving. Recently, I shared 6 lessons learned while working in a SOC [/2016/05/03/6-lessons-i-learned-from-working-in-a-soc/], and today I want to talk about where we at Komand believe the SOC is heading in the future and why. Here are seven pr

Integrating the Logentries Javascript Library With React

React.js has proven itself a powerful contender in the world of Javascript frameworks. Arguably, it has become one of a handful of libraries that all web developers should consider for current or upcoming projects. Understanding how it integrates with other libraries in your technology stack is an important part of that consideration. If you currently use, or are considering using Logentries [https://logentries.com/centralize-log-data-automatically/?le_trial=react-logentries_blog-post_cta-crea

Queuing tasks with Redis

Overview As stated on their official homepage [http://redis.io/], Redis is an open source (BSD licensed), in-memory data structure store, used as database, cache and message broker. Little bit about what Redis can do. It supports data structures such as strings [http://redis.io/topics/data-types-intro#strings], hashes [http://redis.io/topics/data-types-intro#hashes], lists [http://redis.io/topics/data-types-intro#lists], sets [http://redis.io/topics/data-types-intro#sets], sorted sets [http:/

How to Ensure Self Describing Log Data Using Log4Net

In a previous article, The Benefit of Having an Enterprise Logging Policy [/2016/04/06/the-benefit-of-having-an-enterprise-logging-policy/], I presented the case for always using self-describing data formats when logging information. Using self-describing formats, such as key-value pairs and JSON, saves time and effort in terms of indexing and subsequently querying your logs on the backend. Also, logs that use a self-describing data format are easier to understand by anyone, at any time. In t

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 sending in a LEQL query [https://logentries

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, over one million tasks [http://blog.ifttt.com/post/22129854971/one-mil

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. [https://blogs.technet.microsoft.com/johnla/2015/04/26/defenders-think-in-lists-attackers-think-in-graphs-as-long-as-this-is-true-attackers-win] ” Though it certainly doesn’t entirely sum up the challenges of being a defender, it drummed up some interesting conversation/controversy on twitter. Plus as a nice, pithy statement, it has a good r

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 corn
