Chronosphere vs Datadog: Data Shaping, Per-Host Pricing and When Each Fits
Prices and facts checked on vendor pages on Nov 8, 2026.
Chronosphere and Datadog both monitor cloud-native systems, but they start from opposite ends. Chronosphere is built around high-cardinality metrics and a Control Plane that decides which data you keep. Datadog starts with an agent on each host, a published price list, and a long product catalog that includes security, user monitoring, and software delivery. Chronosphere publishes no prices, so this page compares the models, not totals.
The Short Answer
Pick Chronosphere when your pain is metric cardinality and telemetry volume, you run Prometheus-style tooling, and you are willing to go through a sales-led pilot to get a price. Pick Datadog when you want published rates you can model alone, a single agent, and one vendor for infrastructure, APM, logs, security, and user monitoring.
Chronosphere vs Datadog at a Glance
How Chronosphere Charges
Chronosphere does not publish a price list that we could find, and this page does not guess at one. Its documentation describes two contract models. In the consumption model you buy credits and spend them on log bytes persisted or processed, trace bytes persisted or processed, and metric datapoints or persisted series. In the capacity model you contract fixed limits in data points per second and active time series cardinality. Its FAQ adds that it does not price by host or VM, only for the data you choose to retain, and that the Telemetry Pipeline is priced on throughput. Its docs are now published under the name Palo Alto Networks Cortex XCOR, so you may see both names while evaluating.
How Datadog Charges
These are list prices checked on November 8, 2026, all "starting at." Infrastructure Pro is $15 per host per month and Enterprise is $23. APM is $31 per host per month when attached to Infrastructure Monitoring, billed annually, or $36 on-demand. Standalone APM is $36 per host. Logs are $0.10 per ingested or scanned GB, with indexing and retention priced on top. Flex Storage is $0.05 per million events stored per month. Each Pro host includes 100 custom metrics and each Enterprise host 200. Beyond that, the page says custom metrics are billed on usage without a rate, and log-based metrics count toward the allotment. Datadog AI credits start at $500 per 500 credits a month.
Example from published rates only: 20 hosts on Infrastructure Pro plus APM is 20 x ($15 + $31) = $920 a month on annual billing. Ingesting 300 GB of logs adds 300 x $0.10 = $30, with indexing, extra custom metrics, and any other product left out because the page does not give a flat figure for them.
Data Control vs Data Collection
The central difference is where shaping happens. Chronosphere's Control Plane sits in the product: quotas by team or service, usage analyzers for logs and metrics, and shaping rules that aggregate, roll up, or downsample data so you store only what dashboards and alerts need. Chronosphere says this works without touching source code or redeploying services, and its licensing docs meter what is persisted.
Datadog gives you controls too, but in different places. Logs can go to Standard Indexing, Flex Logs, or archives, and the Flex tier does not support monitors or Watchdog. Observability Pipelines runs a Worker in your own infrastructure that redacts, filters, and routes logs and metrics before they leave. The meter stays per host and per unit of each product.
Query, AI and Telemetry Formats
Chronosphere's query layer supports PromQL and Graphite, and it ingests Prometheus and OpenTelemetry. If your dashboards are already PromQL, that carries over. Datadog documents OpenTelemetry in several modes, and says the features available depend on how you instrument and how you send the data.
For AI, Chronosphere documents investigations in which an agent queries metrics, events, logs, and traces from an alert or dashboard panel and shows each query it ran, with a note that the feature is not available to all users. Datadog's Bits AI covers alert investigations, code fixes, and security triage, and is billed in credits.
When to Pick Chronosphere
- Metric cardinality or telemetry volume is what drives your bill today.
- You standardize on Prometheus and PromQL.
- You want per-team quotas on telemetry.
- A sales-led pilot and a negotiated contract are acceptable.
When to Pick Datadog
- You want to estimate cost yourself from published per-host and per-GB rates.
- You want infrastructure, APM, logs, security, and user monitoring from one vendor.
- You prefer a single agent and a self-serve trial.
- Your team wants a broad product catalog more than a data-shaping layer.
Where Sazabi Fits
Sazabi is AI-native observability and security that can run beside either tool. If your logs pass through an OpenTelemetry Collector, you can add Sazabi as an extra exporter and leave your current backend alone. Its agent investigates in Slack and opens issues.
Sazabi ingests OpenTelemetry metrics (Prometheus metrics through an OpenTelemetry Collector) and OTLP traces through the same intake as your logs. It stores each metric data point and each span as a log record that its agent queries alongside your logs, so there is no separate metrics store to run.

Frequently Asked Questions
How much does Chronosphere cost compared with Datadog?
Datadog publishes list prices, for example $15 per host per month for Infrastructure Pro and $0.10 per ingested GB for logs. Chronosphere does not publish a price list. Its documentation describes consumption credits or capacity limits in data points per second and cardinality, and its FAQ says pricing is not host-based, so you need a quote.
Does Chronosphere charge per host?
No. The Chronosphere FAQ says it does not price by host or VM and instead charges for the useful data you choose to retain after shaping. Datadog bills by host for infrastructure and APM.
Can Chronosphere reduce what I send to Datadog?
Chronosphere is a separate backend, not a filter in front of Datadog. Its Telemetry Pipeline routes logs from any source to any destination and is priced on throughput. Datadog has its own Observability Pipelines Worker for the same job.
Which one uses PromQL?
Chronosphere documents PromQL and Graphite support and ingests Prometheus and OpenTelemetry data. Datadog documents OpenTelemetry ingest and its own Agent and APIs.
