SNMP (Network Device Monitoring)

Configuration Settings

The SNMP connector (Simple Network Management Protocol) allows collection and centralisation of information from network devices such as firewalls, NAS systems, printers, and others, integrating them into BusinessLog.

The following parameters are available in the settings section:

  • Enable SNMP

Enables the SNMP connector
Disabled by default

  • Community

Identifier of the SNMP group
Must also be configured on the monitored devices
Default value: public

  • ​Port
    Communication port used by the SNMP protocol
    Default: 161

  • Timeout (ms)
    Maximum time to wait for a response from a device
    Default: 5000 (5 seconds)

  • Retries
    Number of attempts made if no response is received

  • Mode

    • DB → uses the devices listed in the BusinessLog Machine List

    • RANGE → performs a scan across the configured IP address ranges

ATTENTION:

After enabling and configuring SNMP, the BlogService service must be restarted for the changes to take effect.

Device Configuration

For SNMP communication to function correctly, configuration must also be applied on the devices:​

  1. Enable the SNMP service on each device.

  2. Set the same community string configured in BusinessLog.

  3. Where applicable, configure authorised IP addresses for access.

Example SNMP Configuration on FortiGate

Below is a practical example of SNMP configuration on a FortiGate device:

  • Accessing the configuration

  1. Navigate to the menu: “System” → “SNMP”

  2. Enable the option “SNMP Agent” and select “Create New”.

Set the following parameters:

  1. Community Name: must match the one configured in BusinessLog.

  2. IP Address (Hosts): enter the IP address of the BusinessLog server.

  3. Host Type: select Accept queries and send traps.

SNMP community configuration details

  • SNMP Parameters

1. Configure:

- SNMP v1 / v2c → enabled

- Port → 161

2. If required:

- Enable SNMP Traps (v1 / v2c)

- Default port: 162

Data Collection

The collected data is then available within the "Machine List".

Once configured, the system is able to automatically collect information such as:

  • Operating system

  • Device model

  • Serial number

  • CPU and other hardware characteristics

Vulnerability Analysis (CVE)

The collected information is used to verify the presence of known vulnerabilities (CVE) related to:

  • Vendor.

  • Model.

  • Software version.

This enables identification of potentially vulnerable or outdated devices.
