  Filters, the mechanism for allowing and denying events to be handled, have been given a refresh in Sensu Go. These new and improved JavaScript filters give you a way to express business logic through filtering, giving you more awareness of your environment, reducing alert fatigue, and improving performance.

  Community roundup: making the switch from Nagios to Sensu

  Wherever you’re at in your monitoring journey, you’ve probably used Nagios at one time or another. Love it or hate it, a legacy tool like Nagios played a critical role in establishing monitoring as a practice and helped train a generation of operators who required visibility into system dependencies and performance.

  In case you missed it, Sensu Go became generally available in December 2018, and commercial support for Sensu Go became generally available just last month. With these major milestones now in our rearview mirror, it's time to help our customers reach their own milestones of migrating from Sensu to Sensu Go.

  Making sense of time-series analysis

  Even if you haven't heard of data described as a "time-series," you've probably seen examples out in the wild. As the name suggests, a time-series is a representation of an event over a period of time. That could mean representing many different changes: the highs and lows of your curling ice temperature over a year, the number of cars that drive across a bridge every day — or, more relevantly, your application usage data, such as error rates over time or the growing number of activations per day. With enough data collected — that is, over a long enough time period — you can start to forecast future trends using time-series analysis.

  How to measure every API call in your Go app (in fewer than 30 lines of code)

  I recently gave a talk at GrafanaCon LA, which was heavily inspired by my blog post on check output metric extraction. During the talk, I dove into a popular monitoring use case with Sensu, InfluxDB, and Grafana — let’s call it the SIG stack 😎. While I got to share some awesome features in Sensu that ultimately allow users to collect, store, and visualize their metrics, the conference was about Grafana, and folks wanted to see dashboards! Now, I’m a Go dev, not a data scientist, so I don’t have quick access to large sample sets, and while it’s super easy to spin up Sensu in production and start scraping nodes to collect fancy metrics, I wanted something more... and the attendees of GrafanaCon wanted something moar!

  We’re thrilled to announce that the latest release of Sensu Go — version 5.2 — is available today! Sensu Go empowers you to automate your monitoring workflows, offering a comprehensive monitoring solution for your infrastructure, applications, and connected devices. Sensu Go is a massive improvement over the original Sensu (version 1.x), with an emphasis on ease of use and quick time to value.

  In part 1 of this series, I discussed the rise of microservice architecture and the reliance on Kubernetes and Docker for container orchestration and management. I also shared some of the challenges these new technologies present and what sources of data we need in order to effectively monitor our Kubernetes environments. In my concluding comments, I mentioned that Prometheus provides an excellent starting point for collecting and analyzing this data. In this post, I’ll give a brief overview of Prometheus, illustrate how to collect Kubernetes data with Prometheus, and discuss some of the pros and cons of the Prometheus approach.

  As a followup to my previous post, I’d like to walk you through using the Sensu Go sandbox to test upgrading different parts of the event pipeline from Sensu 1.x to Sensu Go. First up we have a Sensu 1.x check configuration using the check_ssh command from Nagios Plugins. This walkthrough can be used as a pattern for converting existing Sensu 1.x check configurations into Sensu Go.

  Now that Sensu Go is out, I thought this would be a great time to circle back and follow up on the Sensu Summit 2018 breakout session concerning Sensu 1.x to Sensu Go workload migration challenges. That session had some great feedback from Sensu users; we’ve been heads down over the past few months putting the pieces together to make it easier to move your existing workloads when you upgrade to Sensu Go and keep your existing Sensu Plugins working while you transition.

  Our industry has long been relying on microservice-based architecture to deliver software faster and safer. The advent and ubiquity of microservices naturally paved the way for container technology, empowering us to rethink how we build and deploy our applications. Docker exploded onto the scene in 2013, and, for companies focusing on modernizing their infrastructure and cloud migration, a tool like Docker is critical to shipping applications quickly, at scale.

  In case you missed it, Sensu Go is here! And, as I wrote about previously, one of the hurdles with migrating workloads from the original version of Sensu to Sensu Go are the changes in the internal event data structure. The existing handlers and mutators in the community maintained Sensu Plugins collection might not work as expected in Sensu Go because of these event data model changes. But friends, I’m here to tell you that we’ve got this problem licked.

  Today is the day: Sensu Go is now in General Availability (GA)! Sensu Go features human-centered design by making it easier to use Sensu; we went from operations having to do the heavy lifting to creating a user-centric, self-service, and highly scalable product.

  At Sensu Summit 2018, Box.com Sr. Infrastructure SRE Trent Baker told the story of how they migrated over 350,000 Nagios checks to Sensu. In this post, I’ll recap that talk, sharing some info about the infrastructure at Box.com, how they migrated a legacy monitoring system, and what’s next.

  As a monitoring company, it’s only natural that we’d always seek more data to inform our product decisions. With that in mind, we created Tessen, a hosted Sensu call-home service. Tessen is opt-in for the current version of Sensu, but will be opt out in Sensu Go (ICYMI, here’s our product roadmap, including the GA release date). Here’s what you need to know, including what we’re collecting and how that data benefits the Sensu Community.
