An observability consolidation playbook for CTOs paying the observability tax — audit the sprawl, choose the right primary modality, migrate one team at a time with both tools running in parallel.
Nobody can debug a problem in one place.
Observability tool sprawl is what success looks like over five years. One tool for metrics, another for logs, a third for traces, a fourth that an acquired team brought in, a fifth that a single director championed, a sixth on a contract nobody can find. The bill grows and the debugging gets harder, not easier.
The consolidation case is simple in theory and hard in practice. Every team has a tool they prefer, every alert has a runbook tied to a dashboard, and every migration risks a regression in MTTR before the consolidation pays back.
Inventory current tools, spend, and usage. Identify the team's primary debugging modality. The decision is which one tool will be the platform — not which tool has the longest feature list.
Map every dashboard, alert, and runbook from each tool to the target. Identify the quick wins — duplicate dashboards, unused metrics, alerts nobody acts on. The quick wins fund the migration and build credibility.
Migrate one team at a time. Both tools run in parallel for two weeks per team. The team learns the new stack on real incidents before the old tool retires.

If your observability stack costs more than it should and debugs worse than it could, the answer is consolidation.
Sometimes, on the margins. The consolidation tool has to be best in your primary modality and acceptable in others. We document the gaps and decide which are acceptable.
Per-team migration with parallel operation. Each team owns its migration. Training in the first month after cutover. The change management is the program.
Parallel operation, runbook migration before alert migration, and a Sev-2 MTTR watch during the two-week parallel window per team. A regression triggers a pause, not a rollback.
Depends on your team's operational appetite. Open source is cheaper but operationally heavier. SaaS is easier but more expensive. We have shipped both.
The acquired tool joins the audit on the same terms as every other tool. If it is the best fit for the team's primary modality, it becomes a finalist. If not, it migrates like any other.
