ClickHouseCalc Audit: Self-Hosted ClickHouse (SigNoz) vs Datadog Log Management Tariffs
In our deterministic ClickHouseCalc model based on public rate cards retrieved 2026-11-12, Datadog bills separately for raw ingestion ($0.10/GB) and live indexed retention ($1.70+ per million events), whereas self-hosted ClickHouse with ZSTD(3) keeps 100% of telemetry searchable on fixed-rate NVMe capacity.
ClickHouseCalc Tariff & Storage Architecture Matrix (self-hosted-clickhouse-vs-datadog-logs)
| OLAP Audit Dimension | Incumbent Platform | Self-Hosted ClickHouse MergeTree |
|---|---|---|
| Published Ingestion Tariff (11.1 TB/mo @ 370 GB/day) | ~$1,110/mo ($0.10/GB published on-demand) | $0.00/mo per-GB surcharge (Included VDS bandwidth) |
| 90-Day Searchable Retention (25% Live Indexed Model) | ~$3,180+/mo + archive rehydration scan fees | 100% searchable on ~4.05 TB ZSTD(3) MergeTree disk |
| High-Cardinality Attribute Billing (`trace_id`, `user_id`) | Metered custom facets & indexed tag quotas | Unmetered `Map(LowCardinality(String), String)` columns |
| Estimated Monthly Run-Rate (Retrieved 2026-11-12) | ~$4,290–$6,800/mo (Zero infra ops labor) | $58.00–$79.00/mo hardware (+ internal SRE maintenance) |

How ClickHouseCalc Quantifies the Exclusion-Filter Visibility Trade-Off
To cap metered log bills, engineering teams frequently drop 75%–85% of HTTP 200 and debug spans at ingestion. In our ClickHouseCalc ZSTD(3) equation, 33.3 TB of 90-day raw OTel spans compresses into ~3.32 TB of active MergeTree parts (+22% merge buffer = 4.05 TB provisioned disk), allowing full-fidelity retention without sampling.
ClickHouseCalc Dual-Sink OpenTelemetry Cutover Strategy & Pending Telemetry
We recommend configuring your OpenTelemetry Collector `exporters:` pipeline to dual-write to both Datadog and your staging ClickHouse node for 14 days to validate alert parity and SRE on-call readiness. Empirical p95 query latency comparison logs remain marked direct host-level telemetry verification on your target instance.
