The Cost Reduction Sprint: 30-50% Savings in Two Weeks

A focused two-week sprint can cut observability costs 30-50%. Here's the day-by-day playbook.

Week 1: Quick Wins (Days 1-5)

Day 1-2: Audit

Pull billing data. Categorize spend by signal type. Identify top-10 cost drivers. Map each to a team/service owner.

Day 3: Drop Obvious Waste

• Delete abandoned dashboards (unaccessed 90+ days)
• Remove duplicate collection agents
• Turn off non-production environment telemetry going to production accounts
• Drop health check logs/traces at the pipeline

Expected savings: 10-15%

Day 4: Log Optimization

• Enable exclusion filters for debug-level logs
• Set up pipeline-level sampling for verbose sources
• Reduce retention for non-critical log sources (30d -> 7d)

Expected savings: 15-25% of log costs

Day 5: Metrics Optimization

• Identify and drop unused custom metrics
• Increase collection interval for slow-changing metrics (10s -> 60s)
• Remove high-cardinality labels from aggregated metrics

Expected savings: 10-20% of metrics costs

Week 2: Structural Changes (Days 6-10)

Day 6-7: Trace Sampling

• Implement tail sampling: keep errors + slow traces, sample rest at 5-10%
• Set up span-to-metrics connector for RED metrics
• Filter health check and heartbeat spans

Expected savings: 50-80% of trace costs

Day 8: Pipeline Architecture

• Deploy OpenTelemetry Collector as a central pipeline
• Add filtering, sampling, and routing rules
• Route different signals to cost-appropriate backends

Day 9: Vendor Negotiation Prep

• Document current usage patterns with data
• Identify commitment level optimization opportunities
• Calculate savings from tier/plan changes
• Prepare competitive quotes for negotiation leverage

Day 10: Implementation and Monitoring

• Deploy all changes to production
• Set up cost monitoring dashboards
• Establish alert thresholds for cost anomalies
• Schedule 30-day review to measure actual savings

Expected Outcomes

Area	Week 1	Week 2	Total
Logs	15-25%	5-10%	20-35%
Metrics	10-20%	5-10%	15-30%
Traces	5-10%	50-80%	55-90%
Total bill	10-15%	20-35%	30-50%

Two-week sprint calendar

Week 1 — measure & quick wins

• Day 1–2: Bill decomposition + top-10 volume sources
• Day 3–4: Drop probe logs, fix DEBUG in prod
• Day 5: Dashboard/alert audit — delete stale

Week 2 — structural

• Day 6–8: Cardinality fixes on top 5 metrics
• Day 9–10: Tail sampling policy for traces
• Day 11–12: Retention tier changes
• Day 13–14: Re-measure; document savings for finance

Typical outcome: $8K–$25K/mo saved on $40K–$80K/mo bills.

What to do this week

• [ ] Assign sprint owner (Staff engineer + FinOps partner)
• [ ] Baseline current $/host and $/GB/day
• [ ] Ship at least one collector filter rule by Friday
• [ ] Schedule day-14 readout with finance
