Dynatrace Application Monitoring vs Skylight

Dynatrace Application Monitoring tracks application performance, availability and user experience to help teams find problems before they affect customers. It brings together real-user experience, response-time metrics, infrastructure and cloud environments. The product automatically detects application dependencies and follows transactions across tiers. Dynatrace says its AI analyzes events to identify breakdowns and can locate problems down to individual lines of code. Real-user and synthetic monitoring support web and mobile apps and end-to-end customer journeys. OneAgent gathers host data, identifies running processes and activates instrumentation for the application stack. Supported technologies listed include AWS, Android, Apache HTTP Server, Microsoft Azure, Docker and Go; the Hub also contains apps, extensions and technologies. Its capabilities include distributed and transaction tracing, dependency mapping, real-user monitoring and log correlation, with a hybrid deployment model. The advertised platform trial lasts 15 days. Full-Stack Monitoring is listed at $58 a month, billed at $0.01 per memory-GiB-hour per 8 GiB host, and includes 10 days of trace retention, extendable to 10 years. Standard Support is available during weekday business hours; Enterprise Success & Support is available 24/7/365.

Skylight is a cloud profiler for Ruby and Rails applications, available through API, Linux, macOS, and web platforms. It ranks endpoints by “agony,” combining popularity with response time, and plots deployments against performance so teams can relate code changes to results. Supported Ruby frameworks include Rails, Sinatra, and Grape. Skylight analyzes Sidekiq, DelayedJob, and ActiveJob background queues, and can flag allocation-heavy code and repeated queries. Endpoint timelines present aggregated, sanitized SQL queries. GraphQL queries are grouped by name in the dashboard and endpoint event sequences. A weekly report identifies improved endpoints, slowdown warnings, and endpoints that declined over six weeks. Each account includes 100,000 free traces per month. Paid tiers start at $20 a month and adjust to monthly trace volume across apps. A 30-day trial is available without a credit card. Open-source apps may apply for free public reporting. Communications are encrypted, and access to customer information is limited to selected personnel and contractors.
