In a previous post, I explained how we made our Ubuntu image 15 times smaller by chiselling a specific slice of Ubuntu for.NET developers. In this blog, I will provide step-by-step instructions on customising your chiselled Ubuntu base images for any use case. I don’t believe in a perfect container base image anymore.
Many of our customers have already embraced mobile transformation and are sending them out in the field to give employees better productivity. For instance, truck drivers now use Android devices for communication and managing their logistics delivery; health organizations use Android tablets to track the location and health status of patients.
Each year of the SRE Report, there’s a trend or anti-pattern that leaps out and makes us pause and reflect. Last year, for example, we found a huge drop in global toil levels. With the whole world working from home for a full year, it made sense that global toil levels would drop, right? But this year, despite the great reopening underway, toil levels dropped even further - it's a paradox, one which no doubt will require its own scrutiny.
Grafana Loki is designed to be cost effective and easy to operate for DevOps and SRE teams, but running queries in Loki can be confusing for those who are new to it. Loki is a horizontally scalable, highly available, multi-tenant log aggregation system inspired by Prometheus. It doesn’t index the content of the logs, but rather a set of labels for each log stream.
We Just celebrated 10 year birthday to Prometheus last month. Prometheus was the second project to join the Cloud Native Computing Foundation after Kubernetes in 2016, and has quickly become the de-facto way to monitor Kubernetes workloads. The plug-and-play experience, just putting Prometheus server and starting to see metrics flowing in tagged with Kubernetes labels, was a compelling offer.
A new year has started and I've been pondering my hopes and dreams for the year to come. In the world of SRE, observability is the most prominent pillar of my work. So, I decided to drill into the topic of observability and what I'd like to see happen in the industry in 2023. Rather than focusing on any tool, technology, or methodology, I'lll be exploring concepts that can be broadly applied in any organization.
Real User Monitoring (RUM) is a method of web performance monitoring that captures user experience metrics on visitors to your website. It is also known as real user metrics, end-user experience monitoring, or simply user monitoring. You can think of Real User Monitoring as an automated way to get user feedback on your website. Not every user will complete a survey or fill out a feedback form, but RUM listens to each one of your users.
Without an active SSL certificate, user contact with the website is no longer secured, making it possible for any malicious entity to access private user information. Users are unlikely to return to the website after viewing a security notice, though. The simplest way to monitor the expiration of your site certificates is to use an efficient, automatic SSL certificate expiry monitoring solution.
