Dynatrace Application Monitoring vs Keymetrics

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.

Keymetrics develops Node.js monitoring software around the open-source PM2 process manager. PM2 Plus provides a real-time web interface for production monitoring, including issue and exception tracking, deployment reporting, real-time logs, custom metrics, custom actions, and notifications through email, Slack, or webhooks. Applications and databases can be viewed together in real time or historically, with an aggregate view across applications. Its issue dashboard can identify when an error occurred, affected servers, the stack trace, the relevant code line, and logs from before the error. The @pm2/io library lets Node.js applications expose values, counters, meters, and histograms. PM2 Enterprise targets high-scale or critical Node.js services, adding customizable dashboards, threshold alerts, stored logs, and production CPU and memory profiling. Enterprise can run as an on-premise installation or as a dedicated or managed instance. Runtime is free; Plus is listed at $79 a month, and Enterprise pricing requires contact. Keymetrics supports API, Linux, self-hosted, and web deployments.
