Adapting Brownfield Deployments to Cloud-Native Technology
summary
Company replaces a patchwork of legacy monitors with Prometheus as One Global Source of Truth, moving from many alert emails to machine-readable metrics and unified PromQL for graphs and alerts. Prometheus deploys in days to deploy, but SNMP at ~300 devices forces a Go SNMP exporter replaced Python because the Python exporter locks machines. Migration runs old and new in parallel, an incident shows an on-call fix in 30 seconds, sales use zero-SLO-quarter reports, and overall change reduced pager fatigue.
