The file that generates the temp value gets created at the OS level every few minutes. In some cases, this file isn’t generated due to OS-level exceptions. This gives rise to a -ve SNMP return value and is sent to the SNMP clients.
Generally, SNMP clients have a built-in mechanism to check the error code along with the SNMP return value as well as to interpret the value correctly which is part of standard SNMP protocol.
