Case Study: Probo cuts monitoring costs by 90% with Last9

Probo Cuts Monitoring Costs by 90% with Last9

Probo, an opinion trading platform, faced significant challenges with its expensive and fragmented monitoring stack, which used tools like New Relic and AWS CloudWatch. The platform experienced massive traffic spikes during popular events, making the vendor lock-in and unpredictable, multi-metric pricing models prohibitively costly. The small SRE team needed a more predictable and unified observability solution to control expenses and democratize monitoring across their engineering teams.

To address this, Probo implemented Last9, a monitoring platform built on Open Standards like Prometheus and OpenTelemetry. Last9 provided a predictable single-metric pricing model based on data ingestion, eliminating per-query and per-user fees. The solution included GitOps workflows for declarative alerting, enabling full automation and team ownership. As a result, Probo cut its monitoring costs by 90%, achieved a single pane of observability for faster root cause analysis, and successfully scaled to handle traffic peaks of 2.5 million requests per minute.
