SNMP Trap
Introduction
The SNMP Trap Observability solution aims to provide detailed insights and comprehensive visibility into various network infrastructure devices such as routers, switches, firewalls, load balancers, and more, leveraging the Simple Network Management Protocol (SNMP). This solution serves as an SNMP enabler for different vendors and models.
Getting Started
Compatibility
SNMP Trap O11ySource supports SNMP versions v1, v2c and v3.
Data Collection Method
vuSmartMaps collects SNMP Trap metrics through a data collector deployed within the vuSmartMaps platform, which uses snmp_trap plugin to retrieve performance and health metrics.
Prerequisites
Dependent Configuration
To configure this O11ySource, create a 'credential' of type 'snmp' under the 'Definition' tab.
Inputs for Configuring Data Source
- Group Name: This field is for grouping devices for SNMP Trap, making it easier to manage devices with common characteristics or within the same network segment.
Devices
- Device IP: Enter the IP address of the device.
- SNMP Credential: Select the SNMP credential from the dropdown list that corresponds to this device.
- Vendor: Select the vendor of the device from the dropdown list
- Model: Select the model of the device from dropdown list.
Applications
Firewall Requirement
To collect data from this O11ySource, ensure the following ports are opened:
| Source IP | Destination IP | Destination Port | Protocol | Direction |
|---|---|---|---|---|
| IP address of the SNMP device | vuSmartMaps Collection/Ingress node IP | 443* | UDP | Outbound |
*Before providing the firewall requirements, please update the port based on the customer environment.
