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.

[TechStory]: Migrating services and databases from an OpenShift (or K8s) cluster to another
My first experience with OpenShift was with a task which was kind of a heavy task, I didn't know anything about OpenShift or K8s! but I was in charge of migrating resources from a cluster to one another! (twice!)

DevOps Tooling Landscape
OpenShift is a container platform from Red Hat that's built on top of Kubernetes. It offers additional features like built-in CI/CD pipelines, enhanced security, and support for multiple programming languages and frameworks.

Collecting Security Logs
Openshift documentation can be hard to find, and installing an cluster without it can be hard. 🤗

OCP Logging
For whatever reason, the PRs for adding CloudWatch and Loki/Vector to the docs haven't merged yet.

My director is mad that I accepted another internal position for a 26% raise when he was told he could only give me a 10%
At your own pace, jump into orchestration using a Kubernetes distribution out there; but really, only do that fairly late in the game (e.g. OpenShift). Sadly, it's quite a jump from containers to orchestration, and there is no "smooth" in-between. Maybe as a prelude, you can look into etcd configuration clusters and Ceph storage clusters first, e.g. using a bunch of VMs on your machine, or a few Raspberry Pis. There are plenty of occasions to pinch your fingers with those, and thus valuable lessons to be learned :-)

OpenShift in a disconnected environment using vCenter - starting from nothing
Part of my job is to help document and assist with getting environment running offline, including OpenShift. While I don't use vSphere the general process is the same, while individual platforms may require different commands the concepts are all the same. Using docs.openshift.com you can find comprehensive guides in how you setup each platform Openshift supports "disconnected". But do realize that not all organizations agree on the exact definition of what disconnected means so you may need to adjust based on what you need. Some allow "sneaker net", others requires you to use old fashioned DVDs to bring all data onsite etc.

Best documentation/discovery process and/or tool for an existing Openshift environment?
You want to be able to rebuild your clusters in case of a disaster, so, any time you install anything, export the yaml. And read https://docs.openshift.com/ for every new version.

About reading logs
We don't pull logs, we forward logs to a centralized logging service.

Self hosted log paraer
opensearch - amazon fork of Elasticsearch https://opensearch.org/docs/latestif you do this an have distributed log sources you'd use logstash for, bin off logstash and use vector (https://vector.dev/) its better out of the box for SaaS stuff.

creating a centralize syslog server with elastic search
I have done something similar in the past: you can send the logs through a centralized syslog servers (I suggest syslog-ng) and from there ingest into ELK. For parsing I am advice to use something like Vector, is a lot more faster than logstash. When you have your logs ingested correctly, you can create your own dashboard in Kibana. If this fit your requirements, no need to install nginx (unless you want to use as reverse proxy for Kibana), php and mysql.

Show HN: Homelab Monitoring Setup with Grafana
I think there's nothing currently that combines both logging and metrics into one easy package and visualizes it, but it's also something I would love to have.
Vector[1] would work as the agent, being able to collect both logs and metrics. But the issue would then be storing it. I'm assuming the Elastic Stack might now be able to do both, but it's just to heavy to deal with in a small setup.
A couple of months ago I took a brief look at that when setting up logging for my own homelab (https://pv.wtf/posts/logging-and-the-homelab). Mostly looking at the memory usage to fit it on my synology. Quickwit[2] and Log-Store[3] both come with built in web interfaces that reduce the need for grafana, but neither of them do metrics.

Retaining Logs generated by service running in pod.
Log to stdout/stderr and collect your logs with a tool like vector (vector.dev) and send it to something like Grafana Loki.

Lightweight logging on RPi?
I would recommend that you run vector as a systems service so you don't have to worry about managing it. Here is a basic config to do that - https://github.com/vectordotdev/vector/blob/master/distribution/systemd/vector.service .
What are some alternatives?
hyperconverged-cluster-operator - Operator pattern for managing multi-operator products
graylog - Free and open log management
okd.io - Source files used to build the https://www.okd.io site.
Fluentd - Fluentd: Unified Logging Layer (project under CNCF)
home-assistant.io - :blue_book: Home Assistant User documentation
agent - Vendor-neutral programmable observability pipelines.
