SigNoz vs Tencent Cloud Application Performance Management

SigNoz is an open-source observability tool for monitoring applications and infrastructure. It brings logs, metrics, traces, and exceptions together with alerting and separate explorers for Trace, Logs, and Metrics. The OpenTelemetry-native design does not require proprietary agents. A Query Builder supports aggregations, filters, and formulas across signal types, while alerts can detect thresholds, anomalies, and Apdex conditions. Users can create dashboards from metrics, logs, and traces. APM charts cover p99 latency, error rate, Apdex, and operations per second, alongside database and external-call monitoring. Distributed tracing uses flamegraph and Gantt-chart views to follow requests across services. SigNoz stores telemetry in ClickHouse with hot and cold tiers. It can run in the cloud or be self-hosted using Docker, Docker Swarm, or Kubernetes. Cloud provides 30-day access to all features for new users; the self-hosted Community option is free but requires users to manage infrastructure, storage, scaling, upgrades, and backups.

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.
