Sematext Tracing vs Tencent Cloud Application Performance Management

Sematext Tracing is an OpenTelemetry-based distributed tracing service for monitoring and troubleshooting microservices and distributed systems. It accepts OTLP over HTTP or gRPC and works with OpenTelemetry Collectors, Jaeger, Zipkin, and compatible instrumentation. Users can filter traces by service, operation, latency, errors, or custom attributes, then inspect waterfalls and spans. Error rates, error types, and stack traces appear within the related request trace, while a Service Map depicts application dependencies and communication patterns. Performance views include latency breakdowns, P50/P95/P99 percentiles, RED metrics, and database query insights. Head-based sampling can retain errors and high-latency requests while sampling normal traffic at lower rates. Alerts can use latency thresholds, error rates, or custom span attributes. The product lists support for languages and frameworks including Java, Python, Go, .NET, Swift, Android, Spring, Django, Rails, React, Vue, and Svelte. Deployment options include Kubernetes, Docker, containers, or bare metal. Pricing is based on spans; the listed starting price is $17.10/mo (annual), and a 14-day trial is available without a credit card. There is no free plan.

Tencent Cloud Application Performance Management (APM) monitors application performance through metrics, traces and logs, and supports analysis and troubleshooting across distributed architectures. It uses probes to monitor applications in real time without code modifications. Traces map request paths across microservices and can include request parameters, transaction data, errors, exceptions, method stacks and instance environment details. APM also discovers application dependencies and shows global topologies for examining application and component bottlenecks.

Its analysis groups performance and exception metrics by dimensions such as API, exception and database call, helping identify slow APIs, SQL statements and recurring exceptions. Named database integrations include MySQL, Oracle, MongoDB and Redis. APM supports OpenTelemetry and works with SkyWalking and Jaeger tracing protocols when reporting configuration is changed. It can associate traces with Cloud Log Service logs, display Cloud Monitor dashboards, and send traces to CKafka with configuration and permissions. Applications outside Tencent Cloud can connect when network access is available. New users receive a 15-day trial, limited to 100 million reported Spans and seven-day trace storage; pay-as-you-go also lists one million Spans per day free for reporting and retention. Pricing includes a $0.02 a month pay-as-you-go rate billed hourly per million Spans reported, plus retention at 0.012 USD per million Spans per day.
