I like Grafana/Loki/promtail etc. it just fits because i already use Grafana anyway for metrics/graphs and such.

Datalust Seq is also nice, as well as Parseable/logstash/Grafana as a combo.

Graylog can do a lot but its too bloated and too hungry for my taste (damn elasticsearch). Src: https://www.reddit.com/r/selfhosted/comments/17velmx/best_platform_for_selfhosted_logs/
