Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

How can my system load be so high if the CPUs are barely being used? Disk IO?
Well... What that's showing is that at some point in time you copied some pages into swap. Since there's no competition for that, they have just stayed there. It doesn't mean that you are seeing memory pressure now, only that at some point since the last reboot your memory usage passed the high water mark which encouraged the kernel to start thinking about swap. If you have sysstat installed you can run through sar to see when that was and even get some idea of whether or not any of those pages written to swap were ever read again, but just having some pages written to swap doesn't mean a whole lot on its own.

How to do a hard reboot remotely on an Intel NUC
You can try sysstat/ iostat. https://github.com/sysstat/sysstat Have a cron or systemd process take periodic snapshots and log them or email them. The swordfish on paper looks fast enough, but it’s on the slow side for a NVMe. For reference I’m running a NUC8 i5 with 16GB of RAM, 1 TB Adata XPG SX8200 Pro and it’s been rock solid. Ubuntu 20.04LTS.
- I made a terminal utility to monitor some system stats. Was wondering if you guys know of anything better or if I should continue dev work on it since we need it?

Release Radar · April 2024 Edition: Major updates from the open source community
It's like Prometheus, but for logs. Okay it's not really to do with the Norse or Greek gods, instead Loki is a horizontally-scalable, highly-available, multi-tenant log aggregation system inspired by the open source project Prometheus. Built by Grafana Labs, Loki is designed for ease of use. Instead of indexing the contents of the logs, Loki provides a set of labels for each log stream. The latest update includes query acceleration with Bloom filters, native OTel support, Helm charts, and more. Check out the changelog for all the major changes and deprecations.

The power of the CLI with Golang and Cobra CLI
Just to give an example of the power of Go for CLI builds, you may have already used or at least heard of Docker, Kubernetes, Prometheus, Terraform, but what do they all have in common? They all have a large part of their usability via CLI and are developed in Go 🐿.

On Implementation of Distributed Protocols
Distributed system administrators need mechanisms and tools for monitoring individual nodes in order to analyze the system and promptly detect anomalies. Developers also need effective mechanisms for analyzing, diagnosing issues, and identifying bugs in protocol implementations. Logging, tracing, and collecting metrics are common observability techniques to allow monitoring and obtaining diagnostic information from the system; most of the explored code bases use these techniques. OpenTelemetry and Prometheus are popular open-source monitoring solutions, which are used in many of the explored code bases.

Golang: out-of-box backpressure handling with gRPC, proven by a Grafana dashboard
Setting up monitoring for a system, especially one involving GRPC communication, provides crucial visibility into its operations. In this guide, we walked through the steps to instrument both a GRPC server and client with Prometheus metrics, exposed those metrics via an HTTP endpoint, and visualized them using Grafana. The Docker-Compose setup simplified the deployment of both Prometheus and Grafana, ensuring a streamlined process.

Monitoring, Observability, and Telemetry Explained
Alerting and Notification: Select a tool with flexible alerting mechanisms to proactively detect anomalies or deviations from defined thresholds. Consider asking questions like "Does this tool offer customizable alerting options and support notification channels that suit our team's communication preferences?" A tool like Prometheus provides robust alerting capabilities.
