How to compare monitoring and observability tools
- Breadth versus cost: all-in-one platforms are convenient and get expensive with data volume.
- Pricing by host, by event or by data ingested.
- Open standards (OpenTelemetry) if you want to keep the option to switch.
- Integration with your on-call and incident process.
How we find monitoring and observability tools
Monitoring shows up in browser SDKs on websites (Sentry, Datadog RUM), in status-page subdomains that point at the vendor, in content security policies and in domain-verification records.
Every company on a tool's page links to the record behind the match. DNS is rechecked weekly and websites monthly, so tools a company stops using drop off the list.
