I think we should have more real standards again. SNMP is great, even though nicer more modern (that is dynamic) interface would be nice. There are, but people still imagine static rrdtool images.
Logging is another topic. Take Syslog for example. Since RFC5424, so over ten years it has support for structured logging, but lacks implementations.
While some defacto standards (S3, etc.) do seem to work, I think it would be good to prevent further vendor-lock-ins. There’s certainly learnings, avoiding so much hard coded, yet ambiguous values, like in syslog are something to avoid, but I think most people understand that nowadays.
Indeed I agreed with you, we should back a bit to basics and good standards.
