Chronosphere Application Observability vs Keymetrics

Chronosphere Application Observability is a cloud service for helping teams find and resolve problems in cloud-native applications and microservices. Chronosphere Lens creates service views aligned with an application’s architecture. Teams can use RED metrics and service-level objectives to understand performance and service dependencies, while metrics, logs, traces, and events are correlated with system changes and their effects. Distributed tracing maps request paths across components to help locate latency and inter-service communication issues. Dynamic trace sampling is offered to balance observability insight with cost. The service accepts open telemetry formats including Prometheus and OpenTelemetry. Listed alerting connections include Slack, PagerDuty, OpsGenie, VictorOps, email, and a general-purpose webhook. Pricing for the Observability Platform is based on useful data retained and customized for each organization; no price is listed. Pilots are typically free and average 2–3 weeks, though large-scale or long-term pilots may be paid. A free trial is offered, but there is no free plan. Customer support includes year-round, 24/7 communication through Slack, Zendesk, or email, with optional office hours and calls.

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.
