Onagre Agent

Overview

The Onagre Agent is a key component of the Onagre monitoring ecosystem, responsible for executing checks on defined resources. It ensures reliable monitoring whether deployed in the public internet or within a private infrastructure.

Schema

Public Agents (Managed by Onagre)

Onagre provides multiple Public Agents, which are fully managed, hosted, and maintained within Onagre’s cloud infrastructure.
These agents are available by default to all users and enable monitoring of publicly accessible resources without requiring any additional setup.

Key Features of Public Agents

Multiple agents deployed and maintained by Onagre.
Run on the public internet to check accessible web resources.
Require no installation or configuration from users.
Available to all Onagre accounts by default.
Provide redundancy and load balancing to ensure optimal monitoring coverage.

Private Agents (User-Deployed)

For organizations needing to monitor internal, private, or restricted resources, Onagre provides the ability to deploy multiple Private Agents within their own infrastructure.
These agents allow monitoring of systems that are not publicly accessible, such as:

On-premise services (e.g., internal web servers, databases, applications).
Cloud-based resources (e.g., private cloud environments in AWS, Azure, GCP).
Network-restricted assets that require monitoring behind firewalls or VPNs.

Two Types of Private Agents

Onagre offers two levels of Private Agents to fit different monitoring needs — from simple host health checks to complete visibility across all your applications and networks.

Core Agents — Focus on system health

Core Agents provide essential system-level monitoring for the host they run on.
They collect key metrics such as CPU usage, memory consumption, disk space, uptime, and load average — offering a real-time view of your server’s health.

Available starting from Pro plans, Core Agents are ideal for teams that want to ensure stable infrastructure without configuring complex probes.

Best for: developers and small teams focusing on host-level performance.
Main goal: Monitor your servers’ health effortlessly.

Advanced Agents — Unlock full monitoring capabilities

Advanced Agents include all Core Agent features and extend them with Onagre’s complete monitoring ecosystem.
They support all 13 sensor types, allowing you to monitor applications, APIs, databases, message queues, certificates, and more — both on-premises and in the cloud.

Available exclusively with Enterprise plans, Advanced Agents are designed for organizations that need deep observability and comprehensive insight into their systems and applications.

Best for: enterprises and IT teams seeking unified visibility across distributed environments.
Main goal: From host metrics to full-stack monitoring — all in one agent.

Key Features of Private Agents

Deploy multiple instances based on your monitoring needs.
Provide full control over internal environment monitoring.
Communicate securely with the Onagre platform via TLS encryption.
Transmit only essential monitoring data, never exposing credentials.
Enable distributed monitoring across different network segments.

Security and Data Protection

Onagre prioritizes security in all agent communications and configurations:

TLS Encryption: All communications between agents (public or private) and the Onagre platform are encrypted.
Minimal Data Exchange: Agents transmit only the required monitoring results, ensuring full data protection.
Secret Management: Sensitive credentials (e.g., database passwords, API keys) are never sent to Onagre. For Private Agents, secrets remain stored locally in the user-managed configuration file.
Scalability & Redundancy: Multiple agents — both public and private — can be deployed to improve resilience and reliability.

Use Cases

Public Monitoring: Use Onagre’s Public Agents to monitor internet-facing services without setup.
Private Monitoring: Deploy Core or Advanced Agents within your infrastructure for secure internal monitoring.
Hybrid Deployments: Combine Public and Private Agents for end-to-end coverage.
Multi-Site Environments: Deploy Private Agents in multiple locations to monitor different data centers or branches.

Summary

Onagre offers a complete and flexible agent ecosystem:
- Public Agents for scalable, no-setup monitoring of external resources.
- Private Agents, available as Core and Advanced, for total control of internal monitoring.

Together, they provide a unified, secure, and redundant monitoring solution that adapts to any environment — from small teams to enterprise-scale infrastructures.
