What are cAdvisor and InfluxDB?
cAdvisor
cAdvisor provides container users with an understanding of the resource usage and performance characteristics of their running containers. It exposes per-container CPU, memory, network, and filesystem metrics.
- Per-container resource metrics
- Live web UI
- Prometheus metrics export
- Auto-discovers containers
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
