snmp-oid详解(最新整理)

1、snmp 常用 oidlinux snmp oids for cpu,memory and disk statisticssnmp stands for simple network management protocol and consists of three key components: managed devices, agents, and network-management systems (nmss). a managed device is a node that has an snmp agent and resides on a managed network. th

2、ese devices can be routers and access server, switches and bridges, hubs, computer hosts, or printers. an agent is a software module residing within a device. this agent translates information into a compatible format with snmp. an nms runs monitoring applications. they provide the bulk of processin

3、g and memory resources required for network management.snmp mibs, oids overviewmib stands for management information base and is a collection of information organized hierarchically. these are accessed using a protocol such as snmp. there are two types of mibs: scalar and tabular. scalar objects def

4、ine a single object instance whereas tabular objects define multiple related object instances grouped in mib tables.mib files for specific devices or systems can be downloaded from hereoids or object identifiers uniquely identify manged objects in a mib hierarchy. this can be depicted as a tree, the

5、 levels of which are assigned by different organizations. top level mib object ids (oids) belong to different standard organizations. vendors define private branches including managed objects for their own products.here is a sample structure of an oidiso (1).org(3).dod(6).internet(1).private(4).tran
