Website Monitoring with SIGNL4

SIGNL4’s core job is to reliably alert operational teams. However, we’ve been asked a couple of times if SIGNL4 can also monitor a website’s uptime. Well, we developed an app and it is now available in the SIGNL4 app gallery. You can now monitor the availability of websites AND get instantly alerted if is goes down. This can be set up in minutes. The new SIGNL4 app “Website Monitoring” checks the availability of a website and queries its URL in configurable intervals.

Introducing Versions API to Automate Error Response for New Code Versions

You know the feeling. You’ve just deployed a new version to production and are monitoring the Rollbar dashboard for any new errors or looking out for any Slack notifications. You’re keeping an eye on the number of new or reactivated errors, their severity level, and triaging to see which errors need to be assigned and to whom. Now what if you could automate these tasks?

Introducing the OpUtils mobile app

Troubleshoot your IP addresses and switch ports faster and smarter! Managing and troubleshooting your network IPs and ports effectively can become difficult if hands-on network monitoring by your IT team is required at all times. Ever wondered if you can monitor your IPs and endpoints on the go? If yes, the solution you need is the OpUtils mobile app.

How to Test Ruby Code That Depends on External APIs

Few things are more frustrating than slow, flaky test suites. You're ready to deploy, wait 20 minutes for CI to run, only to find that a test failure in code you've never touched is blocking you. You dig into the source and find the problem: an external API call. It works (slowly) most of the time. But sometimes the network glitches and it fails. What do you do? In this article, José Manuel shows us several techniques for removing external API dependencies from our tests.

How Raygun increased transactions per second by 44% by removing Nginx

Here at Raygun, improving performance is baked into our culture. In a previous blog post, we showed how we achieved a 12% performance lift by migrating Raygun’s API to .NET Core 3.1. In publishing this, a question was asked on Twitter as to why we still use Nginx as a proxy to the Raygun API application. Our response was that we thought this was the recommended approach from Microsoft. It turns out this has not been the case since the release of .NET Core 2.1.

Community Highlight: How InfluxDB Enables IoT Monitoring of Gas Station Tanks

I recently spoke with Alex Skrivseth, the Operations Manager at The Shed App, and discovered how he’s using InfluxDB to monitor the current levels of gas and diesel at various gas stations. Simply by extracting IoT sensor data, he has been able to provide valuable previously inaccessible data to fuel truck drivers.

How to maximize span ingestion while limiting writes per second to a Scylla backend with Jaeger tracing

Jaeger primarily supports two backends: Cassandra and Elasticsearch. Here at Grafana Labs we use Scylla, an open source Cassandra-compatible backend. In this post we’ll look at how we run Scylla at scale and share some techniques to reduce load while ingesting even more spans. We’ll also share some internal metrics about Jaeger load and Scylla backend performance. Special thanks to the Scylla team for spending some time with us to talk about performance and configuration!
