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.

Need Recommendation: btop like web page for docker
https://github.com/google/cadvisor exports Prometheus metrics, but also offers a simple web-ui for container metrics.

Docker Monitoring Solution?
Perhaps https://github.com/google/cadvisor + prometheus (or influx or whatever else) + grafana?
- How to monitor container exit codes?

Building a realtime performance monitoring system with Kafka and Go
We could have used a much more focussed tool like Prometheus or Cadvisor to gather system stats, but that is not the main objective of this article.

Can ChatGPT Debug and Fix your Docker and Kubernetes Issues?
Result: Interestingly, the GitHub Issue that talks about cAdvisor and Docker Desktop for Mac for running cAdvisor is still open and not fixed.
-
Looking for an open source monitoring solution that will capture specific process info
If you're running things under systemd, you can enable process accounting and use cAdvisor.

How to identify docker containers names? The names do not match those in the CLI after typing "docker ps"
Check this thread if you’re having difficulties, but it might run out of the box these days: https://github.com/google/cadvisor/issues/1846

Webhooks suck, but here are alternatives
In fact, your platform (https://healthchecks.io/) is a prime example of where running customer wasm would be really excellent.
Instead of sending webhooks out to customer configured URLs, you could run a Wasm environment to execute customer code. Off hand, a good use case here is to do further inspection of the event before it gets sent off to some other system - maybe there are cases where you send false-positives and needlessly trigger external system alerts. The customer Wasm could do more introspection on the healthcheck event and make a more informed decision about how to proceed.

What do you use for external monitoring?
i use healthchecks.io and have been very happy

Show HN: OnlineOrNot – Cron Job Monitoring
Is there anything different from https://healthchecks.io/ --- a service I've been using for free for a couple years now?

Prioritize IPv4 over IPv6 in dual stack
Because of this block on the router, and the fact that IPv6 connections are by default preferred over IPv4, many things on the system now cannot access the internet. the only things that can access the internet are for accessing servers that ONLY support IPv4 like my mail.smpt2go or my uptime monitoring scripts for healthchecks.io.
- Ask HN: How do you monitor your systemd services?
- Show HN: Peeng – like Pingdom, but the other way around and simpler

Detecting and alerting for power failures
i use https://healthchecks.io/ and highly recommend it.

Managing re-occurring tasks - Daily/weekly/monthly
We use a heartbeat system. Basically the monitoring continuously sends an alert to a healtcheck system. If that heartbeat fails, PagerDuty sends an alert to the oncall.
