  • Complexity in configuration from scratch, particularly for TypeScript support
  • Limited built-in TypeScript support, requiring separate parsers and coordination with new TypeScript features

Grafana Cloud

  • Active Series (AS) billing model is difficult to predict and control; misconfiguration can cause sudden spikes and unexpected bills
  • Reduced control and customization compared to self-hosted Grafana instances
  • Data sovereignty concerns for organizations requiring on-premises data retention
  • Limited reporting types compared to traditional BI tools for compliance and audit requirements
