Replace Datadog with an open stack you control
Migrate from per-host and usage-priced Datadog to an OpenTelemetry-first observability stack — with validated dashboard, monitor, and service-view parity before you switch a single read.
Target architecture
OTel Collector → SigNoz → ClickHouse → Object Storage
Scope
Everything your team depends on, migrated with parity
Dashboards
Every dashboard inventoried, mapped, and recreated in SigNoz with equivalent panels and queries.
Monitors & Alerts
Alert conditions, thresholds, notification channels, and escalation policies translated to SigNoz.
Service Views
APM service views, dependency maps, and trace-based dashboards recreated with OTel-native data.
Runbooks
On-call runbooks updated with new dashboard links, query patterns, and escalation procedures.
Outcomes
What you get from the Datadog Off-Ramp
Dashboard and monitor parity before cutover
Your SRE team keeps the views they depend on. ExitGraph validates parity in production before switching any reads.
Mirror-mode dual-write with automatic validation
Both systems receive identical telemetry. Side-by-side comparison runs continuously until you are confident.
60-80% reduction in observability spend
Self-hosted SigNoz on ClickHouse eliminates per-host pricing. You pay for compute and storage, not per-metric.
Grounded incident copilot from day one
An AI copilot that understands your services, alerts, runbooks, and migration state — not a generic chatbot.
Architecture
Target-state stack
OpenTelemetry Collector
Vendor-neutral telemetry collection for metrics, traces, and logs. Drop-in replacement for Datadog Agent.
SigNoz
Open-source observability platform with APM, metrics, logs, and alerting in a single pane.
ClickHouse
Column-oriented database optimized for observability query patterns. Handles petabyte-scale data.
S3-compatible Storage
Cost-effective long-term retention with configurable lifecycle policies and query-on-demand.
OpenSearch + Copilot
Semantic search and grounded AI copilot over your telemetry, runbooks, and incident history.
