Introduction
Loki 2.2 — Log Aggregation for Kubernetes — was released on June 15, 2021.
In Kubernetes, the hard part isn’t collecting data — it’s turning traces, metrics, and logs into something you can act on quickly.
In this release: Loki 2.2 enhances log aggregation with improved query performance, better storage efficiency, and enhanced Kubernetes integration for comprehensive log management.
Query Performance Improvements
- Query engine optimizations reduce latency for log queries, especially those involving large time ranges.
- Index improvements accelerate log label lookups and filtering.
- Streaming queries enable real-time log processing and analysis.
- Caching enhancements improve response times for frequently accessed logs.
Storage Efficiency
- Compression improvements reduce storage requirements for log data.
- Retention policies enable more flexible log lifecycle management.
- Object storage integration provides better support for S3, GCS, and Azure Blob Storage.
- Chunk management optimizations improve storage utilization.
Kubernetes Integration
- Service discovery improvements automatically discover Kubernetes pods and collect logs.
- Label extraction enhancements provide better correlation with Kubernetes metadata.
- RBAC integration enables fine-grained access control for log data.
- Operator support simplifies deployment and management in Kubernetes.
Observability & Analysis
- LogQL improvements provide more expressive query language for log analysis.
- Metrics integration enables generating metrics from log data.
- Alerting support enables alerting on log patterns and anomalies.
- Dashboard integration with Grafana provides unified observability.
Getting Started
helm repo add grafana https://grafana.github.io/helm-charts
