ChatOps | Alerting to Slack

groovy-logo-mediumOne of the less used features of Logscape, is the groovy script action when alerting. Despite how powerful this feature is, it’s often left by the wayside.

Analysing and Visualising NYC 311 complaints

In this blog post we’re going to be looking at what some people might call “big” data. No that doesn’t mean big in the conventional sense, it means big in the sense that the single file dataset is 10 Gb in size, and I wanted to make a “big data” pun.

The data in question is a record of NYC’s 311 complaints since 2010, the 6th most popular dataset on the opendata website. “311” is a complaints hotline in NYC, for those interested in following along or investigating the data themselves, it is freely available from the open data website.

Today we’re going to cover

  • Creating a data source and importing the data
  • First look at the data to determine interesting fields
  • Some basic visualisations of the data.

Visualizing UK accident data with Logscape

In my ever onward quest to show to the world how easy it is to get up and started with Logscape, today I’m going to use a Logscape docker container in order to build visualisations based off some publicly available CSV files in no time at all.

Welcoming a new NGINX and Apache app.

For a long time, we’ve had the web app available on our app repository – This covers Nginx, Apache and a whole host of other formats, and whilst functional, it hasn’t been touched in a long time, so it looks a little bit less than pretty.

Given the popularity of Apache and NGINX, and the fact they both use the same out of the box log format, we’re going to give them a dedicated app, and a brand new look.

We’re hoping this works out for everyone. If you’re currently using the existing web app you can continue to do so. But if you’re specifically running NGINX or Apache, and want a change of pace, then read on.

Concatenation or Parameters? Both? What’s the top method of Java logging.

Concatenation or Parameters? Which should we use.

Now it’s undeniable, we techies love to argue about anything we can. Emacs or Vi? Tabs or spaces? Dark theme or Light theme? Brackets on the method line, or the next? to name but a few. We can even see examples of these arguments if you follow discussions on Twitter.

Monitoring a Web Application Stack (Nginx,Haproxy,Apache)

 

Dearchitectureveloping a responsive highly available web application is a complex task with many subcomponents. In the old days , a web application used to consist of a web server, usually Apache with a few cgi scripts to provide content dynamically. As the web grew in size so did the stack, the number of subcomponents,hosts involved increased in number and complexity. A simple web application can now easily consist of a web server, a load balancer, a few databases and a web framework such as Django or Rails. In this blog post we are going to look  at the  different Logscape Apps needed to monitor a web farm.
