What are InfluxDB and Apache SkyWalking?
InfluxDB
InfluxDB is an open-source time series database designed for high write and query loads of metrics, events, and analytics data. It powers monitoring dashboards, IoT data collection, and real-time analytics.
- High-throughput time series storage
- SQL and Flux query support
- Built-in retention policies
- Telegraf collector ecosystem
Apache SkyWalking
Apache SkyWalking is an APM and observability platform for distributed systems, especially microservices and cloud-native architectures. It provides tracing, metrics, logging, and service topology analysis.
- Distributed tracing and metrics
- Service topology maps
- eBPF and OTel integration
- Alerting engine
