“CLOUDY, WITH A CHANCE OF INSIGHTS” Demystifying Observability in the
Cloud PHILIPP SEIFERT-KEHRER 4 July 2024
4 WHAT ABOUT ME? • Developer for 7+ years •
@ Posedio since 2022 • Blood type AB- • Love cats, crocheting & crocheting cats • Monoliths: hehe • Shared libs: not hehe Philipp Seifert-Kehrer
ROADMAP 1. Debugging like it’s 1999 2. Observability Xs and
Os 3. Tracing 101 4.Introducing OpenTelemetry 5. Where benefits?
6 SO, WHAT TO EXPECT FROM THIS TALK? (Re)Gain confidence
to deploy…
DEBUGGING LIKE IT’S 1999 1
8 CLASSICAL DEBUGGING PHD in domain knowledge Sherlock gene
9 LONGEST EMPLOYEE = BEST DEBUGGER? I haven’t moved away
from here in 15 years
10 READING THE TEA LEAVES
11 MONITORING = BYOC Bring Your Own Context
12 BUT, BUT, BUT RUNBOOKS • No documentation > wrong
documentation
13 HELLO CLOUD
14 BUT WHY MONITORING NOT CUTTIN’ IT? Built upon assumptions
Only useful for known unknowns Purely reactive Linear increase of cost Uptime is so 2001
2 OBSERVABILITY XS AND OS
16 WHAT ARE WE TALKIN’ ABOUT? “How well internal states
of a system can be inferred from knowledge of its external outputs”
17 PLATO WAS RIGHT
18 BUT FOR SOFTWARE? Understand inner workings of application Understand
any system state Understand only by observing/external tools Understand without need to ship new code
19 GANG OF 3 Centralized Logging Metrics & Dashboards Distributed
Tracing
20 LET THEM WITHOUT SIN CAST THE FIRST STONE Every
transaction No issues with cardinality Proportional growth of cost Centralized Logging ✅ ✅ 🙅 Metrics & Dashboards ✅ 🙅 ✅ Distribruted Tracing 🙅 ✅ ✅
21 GANG OF 3 GANG OF 3 Centralized Logging Metrics
& Dashboards Distributed Tracing
22 GIMME SOME EXPLORABILITY
TRACING 3
24 SERVICE GRAPH
25 TRACING EXAMPLE
26 ONE TRACE TO RULE ‘EM ALL
27 ANATOMY OF A SPAN
28 EVENTS
29 IT’S ALL ABOUT THE CONTEXT Context propagation Baggage Marshall
Context matters (… even after the 14th blunt)
OPENTELEMETRY 4
31 OTEL OFFERING … that you can’t refuse Open specification
Instrumentation APIs & SDKs Semantic conventions Agent to collect telemetry Optimized protocol OTLP
32 COLLECTOR
33 SEMANTIC CONVENTIONS
34 INSTRUMENTATION Black vs White box Application vs System Distributed
vs Monolith
35 DO’S AND DON’TS Do Don’t Feature flags Be aware
of PII Verbocity level Start off with automatic instrumentation Ignore potential resource overhead Non-standard format Too high default resolution
WHERE BENEFITS 5
37 WHY ALL OF THIS? Less interpretation = less discussion
Foster proactive debugging Reliability Good for application, organization & employee (mental) health No more manual, mental joins Learning opportunity instead of learning prerequisite Link anomalies to distinct version
38 A NEW NON-FUNCTIONAL REQUIREMENT Maintainability Availability Scalability Observability in
the cloud
39 BUT IT’S SO MUCH OVERHEAD, RIGHT?
40 SAMPLING
41 WHAT IF I JUST KEEP LOGGING EVERYTHING?
42 WRAPPING IT UP? Maintainability Availability Scalability Sustainability Better understanding
of architecture More accessible debugging Not all can be fixed… and also should not! Benefits without too much effort possible No panacea
43 Failure is inevitable … so when the shit goes
down, you better be ready
