Logdna

LogDNA, now rebranded as Mezmo, is a log management platform that built a reputation for simple agent-based log ingestion and easy setup. It has since evolved toward log processing pipeline capabilities beyond basic log aggregation. For teams already running LogDNA/Mezmo for log management, the API enables programmatic log ingestion, querying, and alerting. Mezmo's processing pipeline features are newer and represent the platform's differentiation direction, though most existing deployments use it primarily as a log aggregation and search tool.

Authentication uses service keys for log ingestion and API keys for management operations and querying. Service keys are per-ingestion-source credentials. Teams should store ingestion service keys as server-side secrets, as they control log ingestion into the billing-relevant account.

Documentation covers the ingestion and query APIs clearly. Teams using LogDNA under its legacy name may find some documentation still references LogDNA branding. The transition to Mezmo and the processing pipeline capabilities adds complexity to the documentation landscape — teams building new integrations should reference the current Mezmo documentation rather than legacy LogDNA guides.

The API covers log ingestion (sending logs programmatically), log querying (retrieving logs matching filters), alerts, and views. Agents can ship logs directly via the ingestion API without requiring a log forwarding agent, which simplifies architectures where log forwarding infrastructure is not available. The query API enables retrieval of historical log data for automated analysis and alerting workflows.

Reliability is appropriate for a managed log aggregation service. LogDNA/Mezmo is designed for production log ingestion with appropriate availability for log search and retention. Teams evaluating Mezmo versus Logtail or Axiom for new logging infrastructure deployments should compare current pricing and feature direction, as the platform is in active transition.
