In the Log Management World: Are you a Fox or Hedgehog? I’ve recently been reading Nate Silver’s book, “The Signal and the Noise.” In the book, Silver looks at a number of areas where predictions have been made and considers how successful they have been, as well as the reasons why they have been accurate (or not). in the log management world are you a fox or hedgehod Register For DevOps Summit "FREE" (before Friday) ▸ Here I couldn’t help but draw the similarities how most companies use log management tools today. Silver’s particular interests are political forecasting (see www.fivethirtyeight.com) and baseball, particularly predicting player performance. He doesn’t always get his predictions right, but he does explain the rationale behind his predictions and seeks to be unbiased. In his book, he also considers other areas such as meteorology where the models are based o... (more)

Connecting Logs and Metrics: Logentries and Hosted Graphite

As one of the founders of Logentries, I have had the chance to meet 1000’s of our user sover the past few years . Sometimes at tech talks, meet ups, trade shows or wherever our paths have crossed :). One consistent murmur we hear is ‘graphite, graphite, graphite…’ For anyone who doesn’t know, Graphite is a widely used, near real time metrics-gathering system. Although typically used to capture information like CPU or memory usage, Graphite is completely agnostic about the nature of the data being stored inside it. In fact, a very common use case for Graphite is to consume metrics... (more)

Tracing: @Logentries Partners with @NewRelic | @CloudExpo [#DevOps]

Boston, Massachusetts (September 23, 2014) – Logentries, the log management and analytics service built for the cloud, today announced a New Relic integration that provides real-time visibility into log level transactions from client-side devices (such as mobile apps or web browsers) to traditional application and backend servers. The new integration enables users to quickly drill down from an application performance metrics view within the New Relic app into Logentries to see and analyze the matching log events that were generated as part of a specific transaction. Users can now... (more)

Tracing Transactions By @TrevParsons | @DevOpsSummit [#DevOps]

How to Trace Transactions Across Every Layer of Your Distributed Software Stack On every invocation of a method along the transaction data is logged. An example of what might be logged by an APM tool is as follows: unique transaction id - sequence number - call depth - method details - performance data You can then easily piece together full transaction traces by ordering all method calls by sequence number. Further analysis can be applied to this information for a number of purposes. For example, by analysing the transactions, developers can easily construct design diagrams that c... (more)

What Is JSON? By @TrevParsons | @DevOpsSummit [#DevOps]

Three Common Problems Solved With JSON One of the most common questions we get asked by customers is: “What’s the best way to log my data?” My answer is always: "log using JSON format wherever possible.” The next question we often get asked – (but not as much)… Yeah JSON, …Hmmm, what is JSON again? So JSON is: So JSON is: JavaScript Object Notation. But put simply, this is a way that data can be stored in a structured format, where each piece of data will usually have an identifier (known as a key) and a value (which can be in multiple formats). It also can have a nested structure... (more)
