Maybe it could be an issue with the level range. I feel the game well balanced with my char at 150 but same mobs destroys or two shots people at +300 looking at some videos.
This, I used an old board and it didn't work until I replaced the (button) battery . After that, you can troubleshoot the board adding components one by one and listening to the beeps. There's a code. Left the GPU as last element and use the integrated one always until all is working. If a external GPU doesn't work, it could be not enough power. If memory fails, beeps again, try to find a working one and go from there...
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.
It's difficult to fix and not without changes in the code. Most solutions involve fixing those heavy SQL. Tuning them, caching them in redis or memcached or refactor the whole process from scratch.
Thinking on the DDoS part, implement short circuits so reaching those queries must follow a session pattern. It doesn't stop it but you force those script kiddies to make real connections. If they are anonymous then all the heavy queries should be cached due to lack of custom vars. If not, it's a matter of identifying users and banning them automatically.
And where do you think the golden images come from? The steps must be reproducible, versioned, audited, scripted and in the third hands of outsourced minions with 8 or 12h time lapse.
The golden rule of CICD does it survive if you're visited by truck-kun?
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.
