Sophos XGS Firewall

Plugin: go.d.plugin Module: snmp

Overview

Monitor Sophos XGS Firewall (firewall) with Netdata over SNMP. Netdata recognizes the device automatically by its sysObjectID (recognized across 1 device identifiers) and collects the metrics this profile declares — on top of the generic SNMP baseline — with no manual OID configuration.

Netdata's SNMP collector matches the device to the sophos-xgs-firewall.yaml profile via sysObjectID/sysDescr, then polls the OIDs it declares.

This integration is supported on all platforms.

This integration supports multiple instances configured side-by-side.

Default Behavior

Auto-Detection

Auto-detected as Sophos XGS Firewall via sysObjectID/sysDescr.

Limits

The default configuration for this integration does not impose any limits.

Performance Impact

The default configuration for this integration is not expected to impose a significant performance impact on the system.

Setup

You can configure the snmp collector in two ways:

Method	Best for	How to
UI	Fast setup without editing files	Go to Nodes → Configure this node → Collectors → Jobs, search for snmp, then click + to add a job.
File	If you prefer configuring via file, or need to automate deployments (e.g., with Ansible)	Edit go.d/snmp.conf and add a job.

important

UI configuration requires paid Netdata Cloud plan.

Prerequisites

SNMP access

SNMP must be enabled on the device and reachable from the Netdata Agent acting as the site's SNMP hub.

Configuration

Options

Configure the SNMP collector with the device hostname and SNMP credentials. See the SNMP collector reference for all options.

via UI

Configure the snmp collector from the Netdata web interface:

1. Go to Nodes.
2. Select the node where you want the snmp data-collection job to run and click the ⚙ (Configure this node). That node will run the data collection.
3. The Collectors → Jobs view opens by default.
4. In the Search box, type snmp (or scroll the list) to locate the snmp collector.
5. Click the + next to the snmp collector to add a new job.
6. Fill in the job fields, then click Test to verify the configuration and Submit to save.
   • Test runs the job with the provided settings and shows whether data can be collected.
   • If it fails, an error message appears with details (for example, connection refused, timeout, or command execution errors), so you can adjust and retest.

via File

The configuration file name for this integration is go.d/snmp.conf.

The file format is YAML. Generally, the structure is:

update_every: 1
autodetection_retry: 0
jobs:
  - name: some_name1
  - name: some_name2

You can edit the configuration file using the edit-config script from the Netdata config directory.

cd /etc/netdata 2>/dev/null || cd /opt/netdata/etc/netdata
sudo ./edit-config go.d/snmp.conf

Examples

There are no configuration examples.

Alerts

There are no alerts configured by default for this integration.

Metrics

On top of the generic SNMP baseline (the Generic SNMP Device integration — interfaces, system, IP/TCP/UDP, host resources), this Sophos XGS Firewall profile adds the metrics below. Each is collected only where the device exposes the matching OID — inclusion means the profile requests it; availability depends on the device model and software.

23 metrics in 10 groups; each row is a chart context usable in alerts.
