I think of observability as a triad:

- logging (ex tools: Splunk, Sumologic, LogDNA)

- metrics (Prometheus, datadog, Grafana)

- tracing (lightstep, new relic, zipkin)

As mentioned above, observability is the data collected about a system.

When it comes to "measure everything" I've found services that have clients that already grok popular frameworks to be a godsend. We use NewRelic and it's abilty to automatically insturment all rest apis and db transactions is delightful. I could not imagine going back to having to do it manually or guess what information might be useful later.
