Yaya za ka zaɓi ƙararrun hada-hadawa don guje wa gajiyar hada-hadawa da ƙarancin karya?

Question

Accepted Answer

Mahimmaci na asali: **hada-hadawa a kan sigina, ba akan dalilin ba**, kuma **sadar kawai abin da zai iya aiki kuma da gaggawa**. Hada-hadawa mai amo wanda ya kunna jiya-jiya ana damre shi ko watse — saboda haka ainihin haɗari shi ne ba hada-hadawa da ba, shi ne dan lokaci wanda ba zai fahimta ba kuma ya bari babbar jiya.

## Sigina a kan dalilin

Hada-hadawa a kan **SLOs na fuskantar mai amfani** (adadin kuskure, jinkiri, samuwa), ba a kan dalilin ciki kamar "CPU > 80%" ba. Babbar CPU na iya zama mara-cuɓo; abin da akeyima shi ne ko mai amfani ya yi tasiri.

```text
BAD  (cause)     CPU > 80% for 5m            → fires constantly, often no impact
GOOD (symptom)   error-rate SLO burn is fast → fires only when users hurt
```

## Hada-hadawa masu sauki-sauki na dubi-dubi

Alwatika jingina ko tufan a gida sai kuma sai mai daraja ko raskaci. A wajen haka, hada-hadawa akan kama za ka cinye **kasua na kuskure**, ta amfani da dubi-dubi biyu saboda sauri mai cini zai sadar jiya kuma saurin saurin dubi zai sadar jiya ne kawai idan jiya ya ci.

```yaml
# Page: 2% of monthly budget burned in 1h AND still burning over 5m
- alert: HighErrorBudgetBurn
  expr: |
    (slo:error_ratio_1h > 14.4 * 0.001)   # fast window: catch big outages
    and
    (slo:error_ratio_5m > 14.4 * 0.001)   # short window: confirm it's still happening
  for: 2m
  labels: { severity: page }
```

Gajeren dubi ya takaye sadar akan jaji wanda yake ba da samarwa; dogon dubi ya takaye sadar akan sauri mai sauri.

## Sadar a gida vs tikiti vs dashboard

```text
PAGE       actionable + urgent  → wake a human now (SLO at risk, checkout down)
TICKET     actionable, not urgent → fix in business hours (disk 70%, cert in 20 days)
DASHBOARD  informational         → no alert, just visible (per-endpoint traffic)
```

Idan hada-hadawa ba ta aiki ba, ba za ta sadar ba — juyar da ita zuwa tikiti ko panel dashboard. Sannan **tunan cikin lokaci**: bincika kowane sadar, gida wadanda ba wanda ya yi aiki a kansu.

## Me yasa ya zama mai mahimmanci

Gajiyar hada-hadawa halin kurmacin beri ne, ba abin tada sauran ba: jama'a su rike rayoyin da ke da amo, saboda haka fiye da ƙarancin karya da za ka aika, da yawa shine likita na gaggawa tili da ba. Hada-hadawa a kan sigina da dubi-dubi mai kumburin, kuma sadar don abin da za ta iya aiki kuma da gaggawa, sai kome sadar su zama mai nahanni — kuma haka ne ya tabbata dan lokaci wanda basu watse ba.
