Datadog→SigNoz−$23/mo · −$276/yr

Metrics, traces and logs on OpenTelemetry — without per-host pricing.

Medium4 hoursdocker compose ready

Why switch

▸Datadog Pro is $23/host/month and the bill grows with every container you run.
▸SigNoz is built on OpenTelemetry + ClickHouse: vendor-neutral agents, one binary, your data.
▸Same pain dashboard — infra metrics, APM traces, log search — at VPS cost.

The migration

Deploy SigNoz

The compose brings SigNoz, ClickHouse and the OpenTelemetry collector. One host handles small-to-medium fleets.

bashrun on your server

mkdir signoz && cd signoz
curl -O https://raw.githubusercontent.com/aa-humaaan/thealtstack/main/docker-deploy/signoz/docker-compose.yml
docker compose up -d

02
Point OpenTelemetry at it
If you already emit OTel, change the exporter endpoint. Coming from Datadog agents, swap to the OTel collector with the Datadog receiver during transition.
03
Rebuild your top five dashboards
Port the alerts that actually paged you: CPU/memory saturation, error-rate SLOs, queue depth. Everything else was dashboard theater.
04
Ship logs through the collector
Filelog or fluentbit receivers feed the same ClickHouse. Set retention (default 30 days) to size your disk.

Gotchas — read before you cancel

⚠Datadog-specific monitors (synthetics, RUM) need separate tooling — browser RUM exists in SigNoz but evaluate it separately.
⚠OTel collector memory needs a few hundred MB — size the host accordingly.
⚠ClickHouse loves RAM; give the box 8GB+ for comfortable queries.
