Table "sonicwallSensorTable" does not return any values when checking via SNMP MIB browser tool

Simple Network Management Protocol (SNMP) is an application-layer protocol that allows for the exchange of monitoring and managing information between network devices. An Object Identifier (OID) is an address used to uniquely identify managed devices and their statuses.

OID values are used in SNMP monitoring tools to monitor and manage network devices connected over an IP network, such as firewalls, switches, and routers.

SonicWall firewalls have predefined OID values that can be used in SNMP monitoring for tracking various activities.

There are also various free MIB Browser tool which uses SNMP requests to fetch FW data/statistics such as RAM, CPU info.

When clicked on different trees (on the MIB Browser), it fetches the result and then it shows different information such as RAM, CPU etc.

Here iReasoning MIB browser is used.

But while clicking on the option "sonicsensorstable" to get the table, it do not show anything.

When a device does not support Environment Monitoring, then hardware-related MIBs will NOT be built into the binary.

The behavior described in this issue is expected. Also checked with multiple MIB browsers.
