Expectations for network observability
The focus on useful information, combined with the key role of network observability within the automatization of network operations, has raised the expectations that these solutions should fulfill.
Heterogeneous and enriched data
As we have mentioned in the Technological changes subsection, the networks are more diverse nowadays. This means that the data obtained from the different network systems and platforms is no longer as it was in the past. We have been used to leverage mostly on Simple Network Management Protocol (SNMP), and its standard Management Information Bases (MIBs), which made the data gathering and processing pretty consistent.
Today, the information we are looking for comes from the combination of operational data of different types. For example, you may have a Border Gateway Protocol (BGP) session running between an on-premises router connected via VPN to a cloud provider. On each side, you have to use the proper collection...
