I recently wrote an article showing how to configure Prometheus and Grafana for easy metrics collection. In that article, I assumed that the system which should be monitored would use the systemd approach for defining services. I now had to set up the node_exporter utility on a system which

I love VPS providers such as RamNode or ServerCheap which provide excellent performance at a low price point. Unfortunately, when going with most VPS providers, there are no easy built-in facilities for backing up and restoring the data of your servers (such as with AWS EC2 snapshots). Thankfully, there is

On first glance, logging looks like an exceedingly simple problem to solve. However, it is one of these problems which unfortunately become more and more complex the longer one looks at it. I think because of this, there are many frameworks in Java to support logging (since everyone seems to

As mentioned in my previous post, I have long been looking for a centralised solution for collecting logs and monitoring metrics. I think my search was unsuccessful since I was looking for too many things in one solution. Instead I found now two separate solutions, one for log management (using

I have been looking around for an easy to use and reasonable priced solution for managing logs distributed among many servers and system metrics for these servers. I had a brief look into setting up an ELK system but I found that looked quite cumbersome. Recently I came across Graylog

Today I came across a nasty error which occurred in a deployed Java application only but not during development or integration tests. The error went something like the following: java.lang.NoSuchMethodError: java.nio.ByteBuffer.rewind()Ljava/nio/ByteBuffer; at nx.serializerkryo.internal.InternalKryoSerialzer.performToStream(InternalKryoSerialzer.java:33) at nx.
I find that developer documentation is often not very pleasant to look at and, more importantly, often very difficult to navigate. I worked briefly with the PayPal REST API and, while I found that at times it can be confusing to deal with the numerous APIs PayPal offers, aesthetically their

Since I plan to set up a continuous integration server in the near future, I had a quick look around for open source and cloud-based solutions; my main concern was finding something which will work for a small scale project and result in reasonable costs. Jenkins (Open Source) The best

I set up a Jenkins server on a brand new Centos 7 VPS. In the following the instructions for doing this in case you are looking at doing the same: Setting up Jenkins Server * Install OpenJDK Java sudo yum install java-1.8.0-openjdk * Add Jenkins Repo and install Jenkins sudo
I want to start a new category of articles for this blog where I record web or user experience design I come across and which impresses me. I will start today with the homepage of Squarespace. Since they are a web design company, good design can be expected of course.
