Menene observability kuma me ya sa shi muhimmi a cikin tsarin tsarin?

Question

Accepted Answer

**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

```text
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.
```

## Me ya sa observability ta muhimmi

```text
✓ You can't operate/debug what you can't SEE → essential for understanding system behavior
✓ DETECT problems → metrics + alerting catch issues (before/as users hit them)
✓ DEBUG → logs and traces find root causes (especially in distributed systems where a
  request crosses many services — hard to debug without tracing)
✓ UNDERSTAND performance → find bottlenecks, optimize
✓ Maintain RELIABILITY → observability enables fast detection and resolution (lower MTTR)
```

## Observability da monitoring

```text
MONITORING → watching KNOWN metrics/conditions (predefined dashboards, alerts) → "is it
  working?"
OBSERVABILITY → ability to ASK NEW questions / explore the unknown → "WHY is it behaving
  this way?" (debug novel/unexpected issues)
→ observability is broader → understand system behavior, including unforeseen problems
✓ practices: structured logging, distributed tracing (OpenTelemetry), good metrics, alerting
```

## Me ya sa shi muhimmi

Fahimtar observability muhimmin ilimi ne a matakin babbar aiki domin **aikin da kula da tsarin yana bukatar fahimtar halayensu**, kuma observability yana da mahimmanci ga haka (musamman a cikin tsarukan rarraba), don haka yana wani muhimmin gani na tsarin gida.

Observability — fahimtar tsarin ciki daga fitowa ta waje — yana da mahimmanci domin **ba za ka iya sarrafa, aiki, ko debug abin da ba ka iya gani ba**, wanda ya sa shi da mahimmanci dom aiki da tsarin da kyau.

Fahimtar **sanda uku** — **logs** (rijaistun abubuwa don debug na cikakke), **metrics** (auna lambobi don jiya gaida, natashen gida, da alarma), da **traces** (bimawa hanya bugin a cikin sabis) — da yadda suke tare suke ba ka fahimtar abin da ya faru, halin ciki, da hanyoyin bugi, yana da asali ilimi. **Traces** yana da muhimmanci musamman a cikin tsarukan rarraba, inda bugi ya wuce sabis masu yawa kuma debug yana da wahala sosai ba tare da bimawa hanya ba don neman wacce sabis ta kasance jiya ko ta gazawa.

Fahimtar **me ya sa observability ta muhimmi** — yana da mahimmanci don aikin da debug na tsarin, gano matsala (**metrics** da alarma suna kama gida), debug ainihin matsalar (**logs** da **traces**, musamman a cikin tsarukan rarraba), fahimtar aiki, da ba da daidai gano da warware (ƙananan MTTR don aminci) — yana ba wa shahara tashi na aikin.

Fahimtar **observability da monitoring** — monitoring kallo da yanayin sananne ("shine na aiki?") da observability ba da damar bubutu sabuwa da fuskanci ba ("me ya sa shi ke daukar wannan hali?", debug matsaloli sabuwa) — yana nuna muhimmancin zurfafa na ikon fahimtar matsalolin ba a jira ba, muhimmi ne don tsarukan hadaddiyar.

Tsarin tsarin tare da observability tunani (structured logging, distributed tracing, kyakkyawar metrics, alarma) yana da mahimmanci don tsarin da kyau, tsarin da za a iya kumawa.

Tun aikin da kula da tsarin yana bukatar fahimtar halayensu kuma observability (**logs**, **metrics**, **traces**) yana da mahimmanci ga haka — musamman a cikin tsarukan rarraba inda debug yana da wahala ba tare da shi ba — kuma tun sa ba da damar gano, debug, da warware matsala da sauri, fahimtar observability muhimmin ilimi ne a matakin babbar aiki — yana da mahimmanci don aikin da kula da tsarin da kyau, muhimmin gani na tsarin gida (musamman a cikin tsarukan rarraba inda tracing yana da mahimmanci), kuma ya nuna buguwar aiki da ake buƙatar saboda matakin babbar aiki waɗanda suke tsara tsarin da dole a fahimta, debug, da kasance aminci a cikin aiki.
