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.

ebpf_exporter
- Is it possible and good to send data to other host with ebpf?
-
Strange IO issue Linux Ubuntu 18.04
There's also the ebpf_exporter which has modules to let you get per-device IO latency data.
-
Any recommendations structuring jobs and alerts?
For example, we alert when the database starts to get slow, because there's real user impact to slow database queries. We track disk IO latency, but it's for debugging after we get alerted by database alerts. Because database problems could be so many different things. Query plans changing, CPU saturation, etc. Slow reads/writes is just one cause of database problems.
-
Any good tools for doing high resolution latency/jitter/loss tests (e.g. link quality monitoring for video conferencing/streaming services)
There also a prometheus exporter for the data if you have prom set up. https://github.com/cloudflare/ebpf_exporter

vm servers are so slow.
If you have Linux, there is the ebpf_exporter. We use it to monitor real-time disk IO latency, with basically no overhead to the system.
-
Good resources on storage and file systems?
My current go-to to start with storage monitoring is the ebpf_exporter. It allows you to wrap the underlying kernel functions with timing wrappers, which allows you to gather detailed data on every IO that happens. Gather that up into a histogram, and ship it to a monitoring system for visualization.
