What are Robusta and Sensu Go?
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
Sensu Go
Sensu Go is a monitoring event pipeline that treats monitoring as code. It collects check results from agents, processes them through filters and handlers, and integrates with metrics and alerting backends.
- Monitoring as code workflow
- Event filtering and handlers
- Agent and agentless checks
- Built-in metrics support
