Recently we hit the infamous kmem bug in our internal Production Konvoy Cluster. We discovered that we were having this issue after users began reporting a particular CI Job was failing intermittently throughout the Cluster with the following error: From the Pod Logs: From the Kernel Logs.
In the early days of telephony, there were few people who had phone numbers in every town and city. There were just a few numbers to remember and if your brain failed, you could check with a telephone operator, women who always knew (and know) how to listen. Let’s see how a network operating system was born in the middle of the 20th century, right at the center of telephone networks.
The core responsibility of the UK's Driver and Vehicle Licensing Agency (DVLA) is to maintain more than 48 million driver records, more than 40 million vehicle records, and to collect approximately £6 billion ($7.75 billion) a year in Vehicle Excise Duty. The agency is at the forefront of public digital services, and has made significant progress in transforming its IT systems into new cloud-based platforms.
For many companies, cloud costs are among the top investments these days. With a growing number of services, instances and regions, cloud cost optimization is becoming increasingly painful. Companies use cloud management platforms to optimize costs and increase cloud visibility and security. But staying on top of AWS budgets requires proficiency, agility and time—especially when any glitch can result in massive cost bleeds.
Your Network Operations Center (NOC) is responsible for network monitoring, incident response, and other network operations activities — and you want to optimize its performance. To achieve your goal, your NOC team assesses data and explores ways to improve its everyday operations. The team may also implement NOC best practices or craft some of its own. NOC teams manage network availability and performance, along with servers, databases, firewalls, devices, and related external services.

Nothing is more frustrating than feeling like you’ve finally found the perfect trace only to see that you’re missing critical spans. In fact, a common question for new users and operators of Jaeger, the popular distributed tracing system, is: “Where did all my spans go?” In this post we’ll discuss how to diagnose and correct lost spans in each element of the Jaeger ingestion pipeline.
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!
