Agent Architecture

Designed for performance, security, and reliability. The InfraCaptain agent is lightweight and efficient.

Key Characteristics

Lightweight & Efficient

Minimal resource footprint. The agent typically uses less than 50MB of RAM and negligible CPU.

  • < 50MB RAM usage
  • < 1% CPU usage
  • < 10MB disk space

Periodic Collection

Metrics are collected at configurable intervals, not continuously. Default is every 60 seconds.

  • Configurable intervals
  • Event-based triggers
  • Efficient data batching

Event Monitoring

The agent watches for specific events like service restarts, config changes, and process failures.

  • Real-time event detection
  • No polling overhead
  • Intelligent filtering

Safe & Secure

Read-only permissions, encrypted communication, and transparent operation.

  • Minimal permissions
  • TLS encryption
  • Open source code

Technical Specifications

System Requirements

  • Linux kernel 3.10 or higher
  • Systemd or compatible init system
  • Network connectivity (HTTPS outbound)
  • Compatible with Ubuntu, Debian, CentOS, RHEL, Amazon Linux

Resource Usage

  • RAM: ~30-50MB typical usage
  • CPU: < 1% average utilization
  • Disk: ~10MB for agent binary
  • Network: ~1-5KB/minute data transmission

Data Collection

  • Metrics collected every 60 seconds by default
  • Event-based monitoring for immediate alerts
  • Data compressed before transmission
  • Configurable retention policies

Security

  • Runs as dedicated user with minimal privileges
  • No root access required for operation
  • All communication over TLS 1.3
  • Agent validates server certificates

How the Agent Works

From installation to insights, here's what happens under the hood

1

Installation

One-command installation creates a systemd service that starts automatically

2

Registration

Agent authenticates with InfraCaptain servers using a secure API key

3

Collection

Periodic collection of metrics and continuous event monitoring

4

Transmission

Data is compressed, encrypted, and sent to InfraCaptain over HTTPS

5

Analysis

Server-side processing, anomaly detection, and alert generation

Installation

Get started in seconds with a single command

Install on your server:
curl -sSL https://infracaptain.com/install.sh | bash
The installer will:
  • Download and verify the agent binary
  • Create a dedicated system user
  • Install as a systemd service
  • Start monitoring automatically

Engineered for Production

The InfraCaptain agent is built to run reliably on production systems without impacting performance or creating security risks.
