[root@logstash ~]#
1.用snmptranslate把symbol 格式的HOST-RESOURCES-MIB::hrSystem 转换为 numberic 格式的oid,用-On(输出数字格式的oid),使用 -IR(允许“随机”访问 MIB)
命令：
snmptranslate -On -IR HOST-RESOURCES-MIB::hrSystem
[root@logstash ~]# snmptranslate -On -IR HOST-RESOURCES-MIB::hrSystem
.1.3.6.1.2.1.25.1
[root@logstash ~]#
2.用snmptranslate把symbol 格式的HOST-RESOURCES-MIB::hrSystem 转换为symbol 格式的 oid,用-Onf(输出符号格式的oid)
命令：
snmptranslate -Onf -IR HOST-RESOURCES-MIB::hrSystem
[root@logstash ~]# snmptranslate -Onf -IR HOST-RESOURCES
