How much does Datadog cost per host per month?

Datadog infrastructure monitoring lists around $23 per host a month on annual billing. Twenty hosts cost $460. Log ingest is separate and bills per gigabyte. This calculator prices both lines.

Do logs or hosts drive the observability bill?

Hosts are the predictable line and logs are the volatile one. In the default model hosts are about 82 percent of the bill, but a noisy service can push log ingest past the host cost within a month.

Is self-hosted observability cheaper?

Self-hosted tools remove the per-host fee but add compute, storage and on-call time. Set the host price to $5 to model the license cost of a self-run stack against a managed one.

Observability Cost Calculator

An observability bill is hosts plus log volume. The defaults price 20 hosts at $23 each plus 1,000 GB of log ingest at $0.10 per GB, which lands at $560 a month. Hosts are about 82 percent of it, so log volume is the line to watch.
