Application Performance Monitoring with OpenTelemetry
0 likes183 views
OpenTelemetry is an open source observability framework that provides standard APIs and SDKs for instrumenting applications to generate and collect telemetry data. It aims to solve the problem of different APM tools requiring re-instrumentation of code by providing a common data format. OpenTelemetry consists of SDKs that instrument code to generate traces and metrics, exporters to send that data to backends, and a collector service that can receive telemetry in a vendor-agnostic way before exporting to various APM solutions. It is supported by many cloud providers and vendors but does not include its own monitoring backend.

- 3. ▸ Users will tell you your application is slow ▸ Profiling ▸ Performance testing ▸ Performance monitoring How to measure performance
- 4. Observability ▸ To understand OpenTelemetry, understand observability first ▸ Understand the system from outside ▸ Answer the question "Why is this happening?" ▸ Easily troubleshoot and understand the problem
- 6. ▸ To say application is observable, application must be properly instrumented (emit signals) ▸ Properly instrumented = no need of more instrumentation when troubleshooting an issue
- 11. Application Performance Monitoring ▸ Gather data about requests (traces) ▸ Framework boot, SQL, Redis, HTTP calls, business logic,... ▸ Save data into storage, therefore can be aggregate, analysed, create alerts,... ▸ High-level picture about what is happening in requests
- 12. Tracing ▸ Trace (transaction) ▸ Span
- 14. APM tools
- 16. ▸ Each observability back-end has different instrumentation ▸ No standardized data format ▸ Developer must re-instrument code and configure agent every time a new tool is added to the stack No silver bullet
- 18. ▸ Community recognized the need for standardization ▸ In 05/2019, two open-source projects OpenTracing (CNCF) + OpenCensus (Google) ▸ Collection of tools, APIs and SDKs ▸ OTel helps instrument, generate, collect, export telemetry data ▸ "OpenTelemetry is the mechanism by which application code is instrumented, to help make a system observable."
- 19. ▸ Broad industry support and adoption - cloud providers, vendors, services, end users ▸ Vendor-agnostic, vendor-neutral ▸ Pluggable architecture so adding new protocol and format is easy ▸ NOT an observability backend like DataDog or New Relic
- 20. OTel architecture ▸ Agent (part of SDK) ▸ Exporter (part of SDK) ▸ Collector (standalone component) ▸ Telemetry backend of your choice (not part of OTel)
- 21. OTel collector ▸ Optional component ▸ Offers vendor-agnostic receive+process+export of data
- 25. Instrumentation ▸ Differs per language ▸ Automatic instrumentation ▸ Manual
