**Amazon CloudWatch** shine ma'aikacin tantance da gani-gani na AWS — wanda ke tarin **ma'aunin kaya** (metrics), **rukunin tunawa** (logs), da **abubuwan da ke faruwa** (events) daga allunan AWS da aikace-aikacen, tare da **alamu** (alarms) da dasibords. Yana da mahimmanci don fahimtar lafiyar tsarin, gano matsaloli, da amsawa ga matsaloli.Yamta yake kawo da CloudWatch```text
METRICS → numerical data over time (CPU, memory, request count, latency, etc.)
  → AWS services publish metrics automatically; you can publish CUSTOM metrics too
LOGS → collect, store, and search application/system logs (CloudWatch Logs)
ALARMS → trigger actions when a metric crosses a threshold (alert, auto-scale, etc.)
DASHBOARDS → visualize metrics/logs in charts
EVENTS (EventBridge) → react to changes/events in your AWS environment
```## Ma'aunin kaya da alamu```text
→ Monitor key metrics: EC2 CPU, ALB request count/latency, RDS connections, Lambda
  errors/duration, custom application metrics
→ ALARMS act on thresholds:
  - "CPU > 80% for 5 min" → trigger auto scaling (add instances) OR notify the team
  - "error rate > 1%" → send an alert (SNS → email/Slack/PagerDuty)
  - "healthy hosts < 2" → page on-call
→ Alarms enable AUTOMATED responses and ALERTING (know about problems quickly)
```## Rukunin tunawa da gani-gani```text
✓ Centralize LOGS from EC2, Lambda, containers → search and analyze them
✓ Logs Insights → query logs (find errors, patterns, debug issues)
✓ Combine metrics + logs + traces (X-Ray) for full OBSERVABILITY
✓ Set RETENTION; create metric filters (turn log patterns into metrics/alarms)
```## Me ya sa yana da mahimmanci Fahimtar CloudWatch yana da mahimmanci saboda **tantance da gani-gani ne mahalacci don aiki da tsarau a lokacin aiki**, kuma CloudWatch shine babbar ma'aikacin AWS ga haka, saboda haka yana da mahimmanci ilimin aiki na gaske. Aiki da tsarau na lokacin aiki yana buƙacin sanin lafiyarsu, gano matsaloli, da amsawa da sauri — ba za ka iya kula da abin da ba ka iya gani ba. CloudWatch yana da tushe: **ma'aunin kaya** (bayanan lambar misali kamar CPU, jinkiri, da lissafin buƙatu, wanda AWS abubuwa suke aika ta atomatik kuma za a iya canja wa wucin gadi don masa'alatan aplikesho) don fahimtar aiki da lafiya, **rukunin tunawa** (tattara tserewa kuma nemo rukunin tunawa na aplikesho da tsarin) don gano matsaloli, **alamu** don aiki akan matsaloli, da dasibords don kasuwa. Fahimtar **alamu** yana da mahimmanci sai dai: suna bayar da dama ga **amsawa ta atomatik** (misali babbar CPU wanda ke haifar da ƙira mai atomatik don ƙara ƙarfin aiki) da **sanarwa** (sanarwa ga jama'a ta hanyar SNS zuwa imel/Slack/PagerDuty lokacin da hadaddun kurakurai suke aje ko allunan suke zama mara lafiya) — saboda haka matsaloli suna haifar da aiki da gaggawa maimakon zuwan san ba, wanda yana da mahimmanci don tryawa kuma amsa gaggawa. Fahimtar **haɗa-haɗa rukunin tunawa da bincike** (tattara rukunin tunawa daga EC2, Lambda, da jemagi, buƙata su da Logs Insights don nemo kurakurai da gano matsaloli) yana buƙacun da gaskiya don gano matsaloli a cikin tsara wanda ba a maimaita ba, kuma haɗa ma'aunin kaya, rukunin tunawa, da alusi yana bada gaba da **gani-gani**. Tun da aiki da tsarau na lokacin aiki da kyau yana buƙacin tantance (sanin lafiya, gano kuma amsa matsaloli) kuma CloudWatch shine babbar ma'aikacin gani-gani na AWS (ma'aunin kaya, rukunin tunawa, alamu, dasibords), kuma tun da alamu suna bayar da dama ga mahimman amsawa ta atomatik da sanarwa, fahimtar CloudWatch yana da mahimmanci, ilimin AWS na aiki na gaske don aiki da tsarau a lokacin aiki — gani-gani mahalacci wanda ya sa tsarau na AWS yayi aiki, a iya gano kurakurai, kuma tabbatacce, kuma babbar karfin aiki ga duk wanda ke karɓa allunan AWS na lokacin aiki.
