In today’s post, we’ll take a deep dive into Rails migrations. We’ll break down the migration into different pieces, and in the process, learn how to write an effective migration. We’ll learn how to write migrations for multiple databases, as well as how to handle failed migrations and techniques of performing rollbacks. To understand the whole post, you’ll need to have a basic understanding of databases and Rails.

At Sentry, we often get asked how error monitoring is different from APM or logging. To help answer this, I’ve broken down the different types of monitoring into four major categories.

Histograms are one of my favorite topics in the Prometheus universe. Last November, I delivered a talk at PromCon EU 2019 that was titled Prometheus Histograms – Past, Present, and Future. Only the part about the past had to be cut due to time constraints. But I made a promise to resurrect my talk about the history of histograms and I kept my word. In February, I premiered the Secret History of Prometheus Histograms at FOSDEM 2020.

We all know that systems fail. We plan for this with failover partners and system backups. But can you really trust your backups? If you are using Azure monitoring, your backup and site recovery can be complicated. LogicMonitor provides clarity. Our Azure Backup monitoring service provides simple, secure, and cost-effective solutions for backing up and recovering your data using the Azure cloud.

The debate around allowing employees to work from home is now moot. Due to these unusual times, businesses must have the ability to handle the majority of their primary functions remotely.

We’re all wrestling with less than ideal circumstances during the pandemic of COVID-19. Whether you’re sheltering in place or simply practicing social distancing, it’s safe to say we’re all adjusting to a temporary new normal. One commonality is the need for connectivity. If infrastructure fails, business will screech to a halt and we will find ourselves in a new kind of mess altogether.

Cloud Computing Services like AWS, Google Cloud and Microsoft Azure are revolutionizing IT infrastructures at a rapid rate. However, businesses have not completely adopted Cloud services, and many of us are still running hybrid on-premise and cloud solutions. The GroundWork solution is to unify all monitoring, whether it be on-premise or in the cloud.

With the rapid growth of security threats to infrastructure, it’s more important than ever to proactively address vulnerabilities. As an open-source project, built on the trust of users and contributors, Netdata has security concerns at its core. Because we’re committed to code security and quality, we apply Agile principles throughout the software development process. A component of this includes regular static analysis.

We've added the ability to see detailed webhook logs to Oh Dear, showing both the sent request and the received response for all notifications we have sent.

I was excited to attend DevOpsDays in New York City in March of 2020, but then again, who wouldn’t be? A whole week in the Big Apple with Liz Fong and Christine Yen, yes, please! I joined Honeycomb as a product designer in January of 2020, making this my first event as a Honeycomb employee. In addition to meeting our users, it was a chance for me to talk with people just starting their observability journey. As a product designer, my focus is on improving the overall user experience.
