If you’re enjoying Sherlock, why not try Metasploit?
In another direction, perhaps the most CLI fun I’ve had at work was using the phosphor hack of XScreenSaver and piping a lot of useful info to it.
LibreNMS has a very different purpose from your other monitoring options - it’s network monitoring at a large scale, not a generic data storage / data visualization platform. If your goal is to monitor your selfhosted servers and services, this is going to be an odd fit and you’ll probably struggle against it.
Better fits for an out-of-the-box monitoring setup would be CheckMK or Zabbix.
These other “stacks” for monitoring are a little more bespoke. To cover it briefly:
Grafana is popular because it is a fantastic visualization platform. The backend data storage is pluggable.
There are many options for data storage, all that are a little different. Graphite, is push-based and the Statsd compatibility makes it super simple to push your own metrics into it. Prometheus is pull-based. And InfluxDB is more of a time-series database.
