NEVER Do This

NEVER debug "missing metrics" within the first 15 minutes

• Metrics are published every 1–5 minutes
• Processing delay adds another 5–10 minutes
• Total lag from event to visible metric: 10–15 minutes
• Premature debugging creates false investigations

NEVER use = for alarm thresholds with sparse metrics

# WRONG - alarm never fires when metric has data gaps
MetricName[1m].mean() = 0

# RIGHT - handle missing data explicitly
MetricName[1m]{dataMissing=zero}.mean() > 0
