Last9 is a unified observability platform designed for engineering teams, including developers, SREs, and platform engineers, who need to monitor complex, high-scale applications. It consolidates disparate telemetry data into a single interface to reduce tool sprawl and speed up problem diagnosis.

• Unified Data Correlation: Switch instantly between correlated metrics, logs, and traces from a single pane, eliminating the need to juggle multiple tools during an investigation.
• High-Cardinality at Scale: Ingest and query telemetry with very high cardinality (e.g., 20M+ unique series per metric) to monitor granular dimensions like individual users, tenants, or requests without data sampling.
• Real-Time Ingestion Control: Apply rules to filter noise, route critical signals, and manage costs at the point of data ingestion, providing transparency and control over observability spend.
• AI-Native Triage Workflows: Integrate with AI assistants and developer environments to get natural language explanations of alerts and guided root cause analysis directly in tools like IDEs or Slack.
• Open Standards Integration: Works with existing open-source standards and telemetry sources without requiring proprietary agents, allowing for a plug-and-play setup that avoids vendor lock-in.
