Moving from MRTG to Observium

TL;DR
The blog outlines the transition from the legacy monitoring tool MRTG to Observium, highlighting significant improvements in features and ease of use.
- MRTG is an outdated monitoring system (last stable release pre-2012) that requires manual effort and lacks modern features.
- Observium is a modern, feature-rich platform that provides comprehensive monitoring with minimal setup effort compared to its predecessor.
- Observium requires careful setup, including running it at the root of a site and potentially needing port configuration via Apache.
- Crucially, Observium mandates the use of host names (via DNS or local hosts file entries) for SNMP monitoring, rather than just IP addresses.
