Observability shine ikon fahimtar tsarin ciki daga fitowa ta waje — ta hanyar logs, metrics, da traces. Yana da mahimmanci don aikin, debug, da kula da tsarin (musamman waɗanda suke rarraba), inda ba za ka iya sarrafa abin da ba ka iya gani ba.
Sanda uku na observability
LOGS → timestamped records of events (what happened) → detailed, for debugging specific issues
METRICS → numerical measurements over time (CPU, latency, request rate, error rate) →
aggregate health/performance; dashboards; alerting
TRACES → follow a request's path through the system (across services) → understand flows,
find bottlenecks/failures in DISTRIBUTED systems (which service was slow?)
→ together: understand WHAT happened, the OVERALL state, and the PATH of requests.
