• A month is 30 days, or 720 hours.
• Each monitor runs every minute, so 43,200 runs a month.
• Each monitor checks from one location.
• Datadog log events average 1 KB, so 1 GB is 1 million events.
• Datadog and Better Stack are priced for their US region.
• Grafana Cloud prices each server as Kubernetes Monitoring host hours, and leaves out container hours.
• Grafana Cloud log queries stay within its fair-use allowance of 100 times the GB written.
• Grafana Cloud volume bands count total monthly usage, and the free allowance comes off the first band.
• UptimeRobot is priced in euros, as it shows prices in the eurozone, and not converted.
• Every vendor is billed at its month-to-month list price, before tax.
• Each input stops at 1,000,000.

How each vendor bills

Each vendor splits the same work into different meters. At the default usage, Datadog comes to $477.60 a month and Grafana Cloud to $203.18.

• Datadog charges $18 a host for Infrastructure Pro. Logs cost $0.10 a GB to ingest, then a price per million events to index that rises with how long you keep them, from $1.27 for 3 days to $3 for 30. Uptime monitors are API tests at $6 per 10,000 runs.
• Grafana Cloud is free up to its allowances. Past them, Pro is $19 a month plus usage. The calculator prices servers at Grafana's Kubernetes Monitoring host-hour rate, because servers outside Kubernetes are billed by active metric series, which depends on what each one sends. Kubernetes Monitoring also bills container hours past 37,944 a month, which the calculator leaves out.
• Better Stack gives 3 GB of logs a month free. Its free monitors check every 3 minutes, so 1-minute checks start at $34 a month for 10 monitors. In its US region, logs past the free 3 GB cost $0.15 a GB to ingest and $0.08 a GB a month to keep. In Europe they cost $0.10 and $0.05.
• UptimeRobot sells monitors only, in plans sized by monitor count.

Why monitors can cost more than servers

A monitor that runs every minute runs 43,200 times in a 30-day month. On Datadog that is $25.92 a monitor, more than a host. Grafana Cloud includes 100,000 runs, about two monitors' worth, and bills the rest from $5 per 10,000. A plan priced by monitor count, like UptimeRobot's or Better Stack's, costs far less for the same checks.

What the totals leave out

The calculator prices the entry plan that fits your usage at its month-to-month list price. It leaves out tax, annual and committed-use discounts, and add-ons such as APM, tracing or longer retention. When your usage needs a tier the pricing page doesn't list, the row says so instead of guessing.

What Ployz includes

Ployz includes monitoring for every service and server, and searchable logs. Uptime checks come with Ployz Cloud. Your hosting provider bills you for the servers.
