Advanced Agents
Overview
Advanced Agents are private agents that provide full-stack monitoring capabilities. They include everything from Core Agents and extend it with support for all 14 sensor types — enabling deep observability across your applications, databases, networks, and infrastructure.
Subscription
Advanced Agents are available exclusively with the Enterprise plan. See Plans →
Everything in Core, Plus More
Advanced Agents include all Core Agent features out of the box:
- Automatic Heartbeat and Server sensors.
- System metrics: CPU, memory, disk, uptime, load average.
On top of that, they unlock the full range of Onagre sensors for application and network monitoring.
Supported Sensor Types
Advanced Agents support all 14 sensor types available in Onagre:
HTTP Request
| Sensor | Description |
|---|---|
| HTTP Response | Check HTTP status codes and response times. |
| Keyword | Verify that a specific keyword is present in an HTTP response. |
| JSON Content | Validate values within a JSON response body. |
| XML Content | Validate values within an XML response body. |
Network
| Sensor | Description |
|---|---|
| Ping | Check host reachability via ICMP. |
| Port Status | Verify that a specific TCP port is open. |
| Domain Resolution | Validate DNS resolution for a domain. |
| Certificate Validity | Monitor SSL/TLS certificate expiration. |
Databases
| Sensor | Description |
|---|---|
| SQL Compatible | Execute queries on SQL databases (PostgreSQL, MySQL, MSSQL, etc.). |
| Key-Value DB | Check connectivity and data in key-value stores (Redis, etc.). |
Messaging
| Sensor | Description |
|---|---|
| Dead Letter Queue | Monitor dead letter queues for unprocessed messages. |
Files
| Sensor | Description |
|---|---|
| File Checksum | Detect file changes by monitoring checksums. |
System
| Sensor | Description |
|---|---|
| Heartbeat | Confirm the agent is alive and connected. |
| Server | Collect system metrics (CPU, memory, disk, uptime, load). |
Agent Load Monitoring
Advanced Agents report their load percentage to the Onagre platform. This allows you to monitor how busy each agent is and plan capacity accordingly — visible directly in the Onagre UI.
Use Cases
- Full-stack monitoring — Monitor everything from host metrics to application endpoints, databases, and certificates in a single agent.
- Distributed environments — Deploy agents across multiple sites, data centers, or cloud regions for unified visibility.
- Internal databases — Query SQL and key-value databases behind firewalls without exposing them to the internet.
- Private APIs — Monitor internal REST or SOAP APIs using HTTP, JSON, or XML sensors.
- Compliance & security — Track certificate expiration, file integrity, and DNS resolution.
Getting Started
Deploy an Advanced Agent using the same process as any private agent:
Once deployed, configure your sensors in the Configuration guide.
Summary
Advanced Agents are the most powerful monitoring option in Onagre. With support for all 14 sensor types, agent load monitoring, and full Core Agent capabilities included, they provide complete observability for enterprise environments.
