The SRE's Guide to Surviving Tool Sprawl

#sre #devops #tooling #monitoring

14 Tools, Zero Visibility

I joined a startup last year that had 14 different monitoring and observability tools. Datadog for infrastructure. New Relic for APM. PagerDuty for alerting. Sentry for errors. Grafana for dashboards. CloudWatch for AWS stuff. The list went on.

The monthly bill was $18,000. The team had zero unified visibility.

How Tool Sprawl Happens

Nobody wakes up and decides to buy 14 tools. It's gradual:

  1. Backend team picks Datadog
  2. Frontend team prefers Sentry
  3. Platform team standardizes on Prometheus
  4. New CTO brings their favorite APM tool
  5. Acquisition adds another stack

Before you know it, you're running a monitoring zoo.

The Real Cost

The licensing fees are just the beginning. The hidden costs destroy you:

Direct costs:
  Licensing:           $18,000/mo
  Custom integrations: $4,200/mo (eng time)

Hidden costs:
  Context switching:   ~45 min per incident
  Duplicate configs:   ~8 hours/week maintenance
  Onboarding:          2 weeks per new hire
  Missed correlations: ??? (outages we didn't catch)

My Consolidation Framework

Phase 1: Inventory Everything (Week 1-2)

Create a tool matrix:

| Tool       | Category    | Users | Monthly Cost | Overlap With   |
|-----------|-------------|-------|-------------|----------------|
| Datadog    | Infra       | 12    | $6,200      | CloudWatch     |
| New Relic  | APM         | 8     | $4,100      | Datadog APM    |
| Sentry     | Errors      | 15    | $890        | New Relic      |
| PagerDuty  | Alerting    | 20    | $1,200      | Datadog Alerts |
| Grafana    | Dashboards  | 6     | $0 (OSS)    | Datadog Dash   |
Enter fullscreen mode Exit fullscreen mode

Phase 2: Map the Overlaps (Week 3)

For each tool, ask:

  • Can another tool we already have do this?
  • What unique capability does this provide?
  • How many people would be affected by removal?

Phase 3: Define Your Core Stack (Week 4)

You need exactly four categories covered:

  1. Metrics & Infrastructure — One tool
  2. Application Performance — One tool (can be same as #1)
  3. Log Management — One tool
  4. Alerting & Incident Management — One tool

Everything else is a nice-to-have.

Phase 4: Migration Plan (Week 5-12)

Don't rip and replace. Parallel-run for 30 days:

# Phase 4a: Send metrics to both old and new
# Verify data parity
diff <(curl old-tool/api/metrics) <(curl new-tool/api/metrics)

# Phase 4b: Move alerts to new tool
# Keep old tool read-only for 2 weeks

# Phase 4c: Decomission old tool
# Remove agents, cancel license
Enter fullscreen mode Exit fullscreen mode

What We Ended Up With

From 14 tools down to 4:

  • Observability platform: Metrics, traces, logs in one place
  • Error tracking: Kept Sentry (unique source map support)
  • Incident management: Single pager with runbook integration
  • Status page: Customer-facing only

Monthly cost: $18,000 → $7,200. More importantly, MTTR dropped 40% because engineers could find everything in one place.

The Rule I Follow Now

Before adding any new tool, it must pass the "3 AM test": If I'm woken up at 3am, will I actually open this tool? If not, we don't need it.
