Autonomous SRE Capabilities
Sentinel sits next to your applications, providing a clear cockpit and audit log for every automated action taken to keep your infrastructure in peak condition.
Security Autopilot
Integrated with Fail2Ban and CrowdSec to detect brute-force attacks, manage jails, and secure SSH/web entry points. Automatically syncs security state with running services. Blocks 95% of attacks before they reach your application.
Database Autopilot
Analyzes MySQL slow logs, runs EXPLAIN on queries, and detects performance pathologies. Automatically applies safe index suggestions during scheduled night windows. Turn 850ms queries into 12ms instantly.
Cache Guardian
Real-time monitoring for Redis and PHP OPCache. Tracks memory usage, hit ratios, and evictions, surfacing bottlenecks before they impact performance. Proactive health checks for your data layer.
DB Doctor & Diagnostics
A dedicated cockpit for deep database inspection. Monitors buffer pools, long transactions, and table fragmentation with safe, read-only diagnostics and manual fix shortcuts.
Queen Integration
Connects to a global threat intelligence brain for knowledge sharing. Learn from 100+ production servers and sync ROI cost profiles managed via the Queen Knowledge Book.
System Health Dashboard
Mission control cockpit with high-level readiness indicators and global counters for actionable, diagnostic, and fixed issues across your entire infrastructure.

Frequently Asked Questions
Is Basic really free?
Yes, Basic is completely free for 1 production server. You get system monitoring, security detection, and manual database optimizations at no cost.
How does the agent work?
The agent is a lightweight Python script that runs on your server. It monitors MySQL/PostgreSQL, Redis, Fail2Ban, and system metrics. All data is encrypted and sent to Queen for analysis.
What happens if something goes wrong?
Sentinel only applies safe, explainable fixes. Every action is logged in the audit trail. You can disable any autopilot feature at any time.
Which operating systems are supported?
Sentinel runs natively on Ubuntu, Debian, CentOS, RHEL, and Fedora. It installs as a systemd service, so no Docker is required on your server.
Can I use Sentinel with my existing stack?
Yes, Sentinel works with MySQL, PostgreSQL, Redis, PHP OPCache, Fail2Ban, and CrowdSec. It's designed to complement your existing infrastructure.
What about data privacy?
All data is encrypted in transit and at rest. We never store sensitive data like passwords or API keys. You can delete your data at any time.
