Prometheus + node/container exporters. + Grafana for dashboards I haven't touched zabbix in years but last time it didn't support very well dynamic scalations. Also all of them are focused on monitoring infrastructure, you need to pay if you want APM or UX.
Enterprise level, for APM I like datadog, much better than NR. For UX we use acoustic tealeef.
Because kbin isn't Lemmy. They're different applications that use the same interconnection protocol (ActivityPub) so the subs and posts are shared but they are different. Lemmy has a mature API and several clients. Kbin is only available through a browser, their API is still on development or testing there isn't any client yet and the only one known, Artemis, is in closed beta.
OTH kbin supports mastodon tweets not only Lemmy posts.
It would be nice to get mastodon support in Sync.
MacBook pros!
