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.
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
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

ANOMALY DETECTION flag deviation from the normal baseline / seasonality
