RPC Service Level Objectives (SLO)
Service level objectives for RPC endpoints on ChainID 138.
Overview
This document defines the service level objectives for RPC endpoints serving ChainID 138 (DeFi Oracle Meta Mainnet).
RPC Endpoints
Primary Endpoint
- URL:
https://rpc.d-bis.org - Protocol: HTTPS
- WebSocket:
wss://rpc.d-bis.org - Location: Azure (Primary region)
- Infrastructure: Azure Application Gateway + AKS RPC nodes
Secondary Endpoint
- URL:
https://rpc2.d-bis.org - Protocol: HTTPS
- WebSocket:
wss://rpc2.d-bis.org - Location: Azure (Secondary region)
- Infrastructure: Azure Application Gateway + AKS RPC nodes
Service Level Objectives
Availability
- Target: ≥99.9% monthly uptime
- Measurement: Percentage of time RPC endpoints are accessible
- Monitoring: Azure Monitor, Prometheus, Status page
- Alerting: Alert on <99.9% uptime
Latency
- Target: <200ms p95 latency
- Measurement: 95th percentile response time
- Monitoring: Azure Application Insights, Prometheus
- Alerting: Alert on >200ms p95 latency
Throughput
- Target: 1000+ requests/second
- Measurement: Requests per second (RPS)
- Monitoring: Azure Monitor, Prometheus
- Alerting: Alert on capacity issues
Error Rate
- Target: <0.1% error rate
- Measurement: Percentage of requests that result in errors
- Monitoring: Azure Monitor, Prometheus
- Alerting: Alert on >0.1% error rate
Service Level Indicators (SLI)
Uptime SLI
Uptime SLI = (Successful requests / Total requests) * 100
Latency SLI
Latency SLI = p95 response time
Throughput SLI
Throughput SLI = Requests per second
Error Rate SLI
Error Rate SLI = (Error requests / Total requests) * 100
Monitoring
Metrics
- Uptime: Percentage of time endpoints are up
- Latency: Response time percentiles (p50, p95, p99)
- Throughput: Requests per second
- Error Rate: Percentage of errors
- Availability: Endpoint availability status
Tools
- Azure Monitor: Cloud monitoring
- Prometheus: Metrics collection
- Grafana: Metrics visualization
- Application Insights: Application performance monitoring
- Status Page: Public status page
Alerting
Alerts
- Uptime < 99.9%: Critical alert
- Latency > 200ms p95: Warning alert
- Throughput > 90% capacity: Warning alert
- Error Rate > 0.1%: Critical alert
- Endpoint down: Critical alert
Notification Channels
- Email: Operations team
- Slack: Operations channel

- SMS: Critical alerts only
Status Page
Public Status Page
- URL:
https://status.d-bis.org(to be created) - Updates: Real-time status updates
- Incidents: Incident reporting
- Maintenance: Maintenance windows
Status Indicators
- Operational: All systems operational
