All of our services (external REST APIs and internal services) are written in Go. Like others, we wanted to factor out repeated code, but found it hard to do without making things messy or hiding the flexibility of the built-in net/http interfaces. After evaluating many “REST frameworks” for Go, we found some that seemed to have good ideas, but nothing that met our needs well enough. Using these as inspiration and drawing on experience with other languages and their frameworks, we created Siesta. We believe it improves on other projects with similar goals, and is worth trying.

Siesta is our third “REST framework;” the others are ugly internal-only failures we will never open source. Siesta is designed to accomplish the following:

• Handle common tasks such as defining and validating inputs, which can be in the URL or query string. These are strongly typed and flexible.
• More sophisticated routing than …

We are excited to announce that VividCortex now supports MongoDB, a flexible and scalable NoSQL database. After announcing PostgreSQL support in January and Redis in April, our brainiacs continue to create a unified solution for diverse systems.

During the beta period, VividCortex’s MongoDB customers were impressed, as Chris Clarke, DevOps engineer at Parse.ly states: “VividCortex’s highly granular data, including detailed information about each query made against our MongoDB clusters, is invaluable. Installation was a breeze, and the system immediately spotted two problematic queries that had evaded all our other monitoring systems.”

Performance Schema (PS) has been the subject of many, many recent discussions, presentations, and articles.  After its release in MySQL 5.7, PS has become the main actor for people who want to take the further steps in MySQL monitoring. At the same time, it has become clear that Oracle intends to make PS powerful with so many features and new instrumentation that old-style monitoring will begin to look like obsolete tools from the Stone Age.

This article will explain PS and provide guidance on what needs to be done in order to use it effectively.

What I am not going to do is to dig into specific performance issues or address polemics about what PS is and what, in a Utopian vision, it should be. I have seen too many presentations, articles and comments like this and they are not productive, nor are they in line with my target which is: keep people informed on how to do things EASILY.

We’ve added a fullscreen (kiosk) mode to VividCortex, perfect for livestreaming a dashboard to a big monitor on your wall. Fullscreen mode uses native browser functionality to request fullscreen access, so there’s no need to try to hide your tab bar. Simply click the little icon in the top right corner of any screen:

The app will not only go into fullscreen mode but will hide all the “chrome” used for navigation. You will see a minimalistic header that just shows the time interval you’ve selected.

Naturally, you’ll want to start livestreaming before you fullscreen, so your monitor will refresh with updated data continually.

Enjoy!

And remember, VividCortex makes you look smart …

This Log Buffer edition sheds light on the ongoing innovations and updates in the SQL Server, MySQL and Oracle realms.

I just dove into Tungsten replicator very recently as I need to replicate from Amazon RDS to Redshift. I’d heard a lot of great things about Tungsten, but had yet to really dig my heels in. Join 28,000 others and follow Sean Hull on twitter @hullsean. I fetched the binary and began to dig through … Continue reading Wrestling with bears or how I tamed Tungsten replicator →

Developer Studio.. JavaScript.. ClusterControl DSL.. database clusters.. huh? what the heck is going on here? This might seem like a mix up of random tech terms, but it’s really a pretty cool feature that we’ve just released.  

With ClusterControl 1.2.10, we introduced our new, powerful ClusterControl DSL (Domain Specific Language), which allows you to extend the functionality of your ClusterControl platform by creating Advisors, Auto Tuners, or “mini Programs”. The DSL syntax is based on JavaScript, with extensions to provide access to ClusterControl’s internal data structures and functions. The DSL allows you to execute SQL statements, run shell commands/programs across all your cluster hosts, and retrieve results to be processed for advisors/alerts or any other actions.
