System contact details	MIB: SNMPv2-MIB The textual identification of the contact person for this managed node, together with information on how to contact this person. If no contact information is known, the value is the zero-length string.	`SNMP_AGENT`	15m	system.contact[sysContact.0]
System description	MIB: SNMPv2-MIB A textual description of the entity. This value should include the full name and version identification of the system's hardware type, software operating-system, and networking software.	`SNMP_AGENT`	15m	system.descr[sysDescr.0]
