This exporter is the recommended way to expose SNMP data in a format that Prometheus can ingest. To simply get started, it's recommended to use the if_mib module with switches, access points, or routers using the public_v2 auth module, which should be a read-only access community on the target device. Note, that community strings in SNMP are not considered secrets, as they are sent unencrypted in SNMP v1 and v2c. For secure access, SNMP v3 is required.
