Robusta is an open-source Kubernetes alerting and remediation platform built on a Python playbook engine. When a Prometheus alert fires, Robusta executes the configured playbook: enriching the alert with pod logs, resource graphs, and Kubernetes object state, then optionally executing operational actions (restart, scale, rollback, command execution) based on the alert type and severity.
Playbooks are Python classes that receive the alert payload and Kubernetes context, execute actions using the Robusta SDK, and post enriched notifications to Slack, Teams, or Datadog. A library of pre-built playbooks covers common Kubernetes failure patterns.
HolmesGPT (commercial tier) adds AI-powered cross-system investigation across Kubernetes, AWS, GCP, and OpenShift. Open-source core under MIT license.
Key Features
Python playbook engine: alert-triggered playbooks written in Python execute enrichment, investigation, and remediation actions using the Robusta SDK — customizable beyond the pre-built library
Alert enrichment: automatically attaches pod logs, CPU/memory graphs, Kubernetes events, and related resource state to each Prometheus alert notification
Automated remediation actions: configurable per alert type — OOMKill triggers limit adjustment, CrashLoopBackOff triggers restart, custom conditions trigger arbitrary kubectl commands or scripts
HolmesGPT AI investigation (Pro): AI-powered root cause analysis spanning Kubernetes, AWS, GCP, and OpenShift using natural language — runs on demand or on alert trigger
Open-source core under MIT license: pre-built playbooks covering CrashLoopBackOff, OOMKill, node pressure, HPA failures, and other common patterns at no cost
Multi-destination notifications: Slack, Teams, PagerDuty, Datadog, and custom webhooks with enriched alert payloads; each notification channel configurable per playbook
