Loki quick tip: How to use a Loki datasource in your Grafana dashboard

In Grafana, Loki isn’t just for log visualization anymore. Now there’s a simple way to use a Loki datasource as a metric datasource in your graphs. This used to require a hack to make it work – adding Loki as a Prometheus datasource – and the process was very tedious. But Grafana v6.6 integrates Loki even better than before.

Parsing Query Strings in .NET Core

We recently needed to parse and modify some query strings while building Request Metrics. Query string parsing has never been pleasant in .NET, has it improved in .NET Core? We were familiar with HttpUtility.ParseQueryString() for the task, but that API has a major landmine. With the release of .NET Core, Microsoft took another swing at it. We figured we’d try the new way and see how they did! If you want the fully uncensored version, check out the video above.

Predicting the Future With Linear Regression in Ruby

The world is full of linear relationships. When one apple costs $1 and two apples cost $2, it's easy to figure out the price of any number of apples. But what happens when you have 100s of data points? What if your data source is noisy? That's when it's helpful to use a technique called linear regression. In this article Julie Kent shows us how linear regression works, and walks through a practical example in Ruby.

How private-sector tech companies are stepping up to the COVID-19 fight

In a drastic worldwide attempt to curb the spread of COVID-19, one third of the global population is now experiencing some form of lockdown. For the millions of Americans who have filed for unemployment over the last few weeks, there is nothing to do but wait. But for those on the frontline, time has never felt so limited.

Post SCOM Alerts to a REST endpoint

I wrote a quick script the other day to pull some SCOM Alert data for testing and thought I’d share a summarized version for anyone looking for easy options to extract their SCOM data. The below sample script pulls all of the SCOM Alerts from your Management Group and pushes them via REST to a specified endpoint. Using the Operations Manager module makes this pretty quick and painless. I’ve called out a couple of easy tweaks you can make below to the script itself.
