When you visit a webpage that is down, most of the time you'll see an error: you'd see a 404 error if the page can't be found or a 503 if the server isn't unavailable. Although this is not what you want to see, it is helpful. You know that the site is down and have a rough idea why. But sometimes you don't see an error... just a spinning wheel.

In our appropriately named Life at Sentry series, we talk to Sentry employees about what life is like at Sentry (and how they ended up here). In this edition, we’re chatting with Chloe Condon, Developer Evangelist(a) at Sentry, about stumbling into tech, imposter syndrome, and not getting cast as Carrie in “Carrie: The Musical.” Take a look at our available jobs if you’re interested in joining us.

One of the key performance indicators of any system, application, product, or process is how certain parameters or data points perform over time. What if you want to monitor hits on an API endpoint or database latency in seconds? A single data point captured in the present moment won’t tell you much by itself. However, tracking that same trend over time will tell you much more, including the impact of change on a particular metric.

In case you haven’t seen or used it, there is a “Bulk Actions link” just under the “Add Monitor button” in the left sidebar. It simply opens the “Bulk Actions dialog” and presents a set of actions that can be applied to monitors in bulk. This feature is now more powerful with a few important additions.

We all read them, and we all have our favorite technology news and media sites. Now that mobile dominates the market and Google has shifted to ranking based on mobile performance, we thought it would be fun to see how ready the top 50 technology news and media websites are for the shift using our free Website Speed Test Tool.

Node.js is an asynchronous JavaScript runtime that is used to develop highly scalable network applications. To help provide more visibility into these dynamic environments, we’re pleased to announce that Datadog APM has officially released support for monitoring Node.js applications, which joins our existing support for Java, Ruby, Python and Go.

Icinga 2.9.0 provided many many bugfixes and one change has unfortunately been overseen. If you use an init system different to Systemd (e.g. Sysvinit) or the “-d/–daemonize” option in your containers, issue #6445 causes troubles. This is visible with logging, cluster connects, IDO database writing. Users reported problems on CentOS 6, SLES 11, Ubuntu 14, Debian 8, Gentoo (both with Sysvinit).

Managed IT services have undergone significant change and evolution in a very short time. As an IT service provider, remote monitoring and management (RMM) is at the core of your business, allowing you to manage a large number and variety of endpoints. At the same time, your clients have grown to expect 24×7 uptime with outstanding customer service, potentially leading to some growing pains on your end.

I’m gearing up to attend my first Sensu Summit this year, and have gone back and watched last year’s talks that I missed. There were a lot of great talks! One technical talk that really caught my eye was Lee Briggs on sensu-wrapper. Lee introduced a wrapper utility he wrote to make it easier to use the Sensu client socket to monitor shell executables for correct operation. In this post, I’ll break down why his sensu-wrapper command is so useful.

It’s Monday which means it’s time to once more tell you about some updates that that the StatusCake team have rolled out over the last week.
