Tun fatan matsaloli kafin mai amfani su komarje?

Question

Accepted Answer

Jiya ce to auta mabuja matsaloli **kafin shafi** — nemo lalacewa yayin da still akwai sararin amfani. Wannan nufin lura **jimawun bagun** alfahari, bayyana **SLO tare da kashin kudin** kulu, da aiwatar rashin jajir maimakon jira ai daidai.

## SLO da kashin kudin

SLO yana karkatar da amintattun kaya zuwa lambar (misalai 99.9% sauri sun yi nasara). Sauran 0.1% ita ce kudin kimaninka **kashin kudi**. Tana **cikin hanya bukar** sau ake tsara karni ko mairo-makada — ko ba waje ba ba kusan kala gida ba kuma gidanmu ba a lura ba.

```text
SLO 99.9% → 0.1% error budget/month (~43 min of downtime)
burn rate rising fast → you'll exhaust it in 2 days → alert NOW, while it's fixable
```

## Tubar aiwatarwa, ba da kayyananin arbani kaikai ba

```text
SYNTHETIC MONITORING  scripted checks hit critical paths on a schedule
                      (login, checkout) → fails even at 3am with zero real traffic
HEALTH CHECKS         /healthz endpoints + dependency checks → load balancer
                      pulls bad instances before users hit them
RUM (real-user mon.)  measure latency/errors from actual browsers/devices →
                      catches issues only some users/regions see
```

```text
LEADING INDICATORS   saturation (CPU/mem climbing), queue depth growing,
                     connection-pool nearing limit, latency CREEPING up
ANOMALY DETECTION    flag deviation from the normal baseline / seasonality
TREND ALERTS         "disk will fill in 4h at this rate" → act before it's full
