Observability vs Monitoring
So what exactly is observability? Is it just a new-fangled term for 'monitoring'? Well, no. Observability goes further than mere monitoring. Observability involves the combination of 3 pillars – Metrics, Logs, and Tracing – to give a much more in-depth view of what your application is doing. Observability offers proactive insights into how your application and/or infrastructure are likely to behave, whereas monitoring is only reactive in nature.
