New indexed-log retention tiers and explicit per-custom-metric charges make Datadog bills harder to predict and easier to overrun.
Before
Flat host + ingested logs
After
Host + indexed-log tiers + $0.05 per custom metric / mo
Datadog refined its metering with indexed-log retention tiers and clearer custom metric charges (~$0.05/metric/mo beyond allotment). High-cardinality tags can silently multiply custom metrics, so governance on tagging is now a cost-control lever.
