I see partial structures and then JSON string as is and then some long blob of string no one can understand what it is with no new lines.
What devs want are pretty simple, structured log with table layout without repeating the column names on every row to make it look insanely verbose for any human to consume.
I'm picking up bits of open source apps to build a decent solution with Vector (which has awesome Vector remap language to parse strings into structured data if it isn't already) and throw it into ClickHouse to view it from Metabase.
Apparently, Kibana, Graylog or even Grafana are pretty bad at displaying logs to even feel tiny comfortable reading it every day.
Logging is such a crucial part of developer life and not sure why that there aren't any sane open source solutions.
