Network monitoring, as you already know, is not something new. Network administrators have been gathering network operational data for years to understand how the networks behave. This approach, which we could define as classic network Operations, Administration, and Management (OAM) methods, has encountered some challenges that stand in the way of meeting current expectations.

It’s not one or the other. To support modern network observability, we will leverage all the available options. So, let’s start with a recap of the challenges of traditional monitoring.

When someone asks you about network monitoring, the first two protocols that will come to your mind are probably SNMP (for metrics) and Syslog (for logs). Both have been the foundation...
