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.

Monitoring MySQL with Prometheus and Grafana in Docker
To install it you can follow the instructions in the GitHub repository and you can run it in a Docker container as well.

Are there any tools that will suggest beneficial indexes to add? / Why doesn't MySQL/MariaDb have this functionality built in?
Prometheus and the mysqld_exporter can provide lots of good, detailed, real-time metrics on your performance.
-
Fetching date of the last time a DB was accessed.
What I would do is to persist those between restarts. If you need metrics, something like the prometheus-mysql-exporter (or any other scrapping process) can periodically query mysql for metrics, including (although not by default) performance_schema. That is what I would suggest to solve your monitoring (and would get you a robust and maintained metric system), plus counters will automatically solve the "reset to 0" on restart.
- Is it posible to get database based bandwidth consuming stats on a MySQL server?

Best Practices on Server Administration
As u/mtocker said, best practice today is to use a modern metrics-based monitoring platform like Prometheus and mysqld_exporter. This does much more than just "not offline".

Top key metrics for monitoring MySQL
To start monitoring MySQL with Prometheus, you’ll need to deploy the MySQL Exporter in your cluster. To deploy the exporter, you can use the example files provided below.

Anyone using official mysqld exporter?
I'm not MySQL user, but I'm writing a custom exporter for my NoSQL clusters, so studying the official mysql exporter (https://github.com/prometheus/mysqld_exporter) just for reference.
-
How do you manage exporters?
For example mysqld_exporter , you supply mysql connection details while mysqld_exporter itself running inside k8s as a just another container, then prometheus will scrape the mysqld-exporter. Deploying mysqld-exporter is just another Deployment.

Monitoring InnoDB Cluster members using Prometheus and MySQL Exporter
When manually rejoining the cluster fails, syncing the server's replication logs manually is an especially harrowing experience. These occurrences were greatly reduced by upgrading our cluster to the 8.0.x series of releases, making use of the Auto Rejoin feature, and monitoring our clusters members using MySQL Exporter

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.
