1. Sebastian Grodzicki Engineering Manager @ Elastic Infoshare 2020 Combining Logs, Metrics, and Traces for Unified Observability
2. #ObservaBLT Observability = + +
4. Higher resource utilization increases monitoring complexity • Orchestration/Hypervisor • Dynamic/ephemeral jobs • You can no longer "point" to where that job lives
 Shift to cloud-native yields maintainable code, with costs • Traditional licensing models don't scale as well as your applications • Hurdles with autoscaling Monitoring Complexity Hardware & software trends are evolving in tandem Evolving Architectures ~↑ Monitoring Complexity
6. Applications VMs/Containers Other DBs, Services & Middleware Orchestration Infrastructure APM Metrics Logs Uptime Uptime APM Metrics APM Logs APM APM Metrics Logs Uptime Metrics Logs Uptime APM
7. Development Team Ops: Log Monitoring Uptime Response Time Uptime Tool Ops: Infra Monitoring Web Logs App Logs Database Logs Container Logs Log Tool Ops: Service Monitoring Real User Monitoring Txn Perf Monitoring Distributed Tracing APM Tool Container Metrics Host Metrics Database Metrics Network Metrics Storage Metrics Metrics Tool Status Quo: Siloed Collection of Tools
8. Observability is a search use case
9. APM Data Uptime Data Metrics Data Log Data Elastic Approach to Observability Uptime Response Time Correctness Certificate Validation Web Logs App Logs Database Logs Container Logs Real User Monitoring Txn Perf Monitoring Distributed Tracing Dependency Mapping Host/Container Metrics Database Metics Network Metrics Storage Metrics Dev & Ops Teams
10. Unified User Interface Same UI for KPI summaries and root-cause analysis
11. Correlate multiple data sources for more intelligent anomaly detection Unified Machine Learning
12. Trigger off any operational data to provide unified SLA monitoring Unified Alerting
13. Pricing aligned with business value Unified Licensing Model PER AGENT $$$$ PER HOST $$$$ PER INGEST $$$$ PER MONITOR $$$$ PER ADD-ON $$$$ • Intuitive Single, unified pricing model. No add-ons. • Cloud native No problem using with container workloads and serverless. • Future proof You pay for capacity and are not locked into a specific use case.
