What are InfluxDB and Robusta?
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
Robusta
Robusta enhances Prometheus alerts for Kubernetes with enriched context, automated troubleshooting, and notifications to Slack and other channels. It helps teams understand and respond to cluster issues faster.
- Enriched Kubernetes alerts
- Automated remediation playbooks
- Slack and Teams notifications
- Crash and OOM diagnostics
