我一直在尝试在tutorial之后通过SNMP获取自定义MIB的值。我正在使用net-snmp 5.7.3。我已使用此MIB以及相应的codes和this。
我的设置：我有两个VM，两个Ubuntu 16，一个是 snmp-server ，IP：192.168.5.20，另一个是 snmp-agent IP：192.168.5.21
我做了MIBS=ALL和export MIBS。在代理上，我已经成功编译了我的MIB并获得了预期的输出。我的代码文件位于路径/home/snmp-agent/Desktop/proj/net-snmp-5.7.3/agent/mibgroup/中。我像这样重新配置net-snmp：
./configure --with-mib-modules="pingCtlTable pingResultsTable pingProbeHistoryTable"
make
make install
一切都很好。当我在代理上snmptranslate时，我得到了：
root@snmpagent:~# snmptranslate -On DISMAN-PING-MIB::pingResultsTable
.1.3.6.1.2.1.80.1.3
root@snmpagent:~# snmptranslate -On DISMAN-PING-MIB::pingCtlTable
.1.3.6.1.2.1.80.1.2
root@snmpagent:~# snmptranslate -On DISMAN-PING-MIB::pingProbeHistoryTable
.1.3.6.1.2.1.80.1.4
服务器上的输出，当我这样做时：
snmpget -v2c -c public 192.168.5.21 sysDescr.0
SNMPv2-MIB::sysDescr.0 = STRING: Linux snmp-agent 4.10.0-33-generic #37~16.04.1-Ubuntu SMP Fri Aug 11 14:07:24 UTC 2017 x86_64
但是当我从服务器运行snmpget时，我得到了这三个错误：
snmpget -v2c -c public 192.168.5.21 DISMAN-PING-MIB::pingCtlTable.0
DISMAN-PING-MIB::pingCtlTable = No Such Object available on this agent at this OID
指定OID时的输出：
snmpget -v2c -c public 192.168.5.21 .1.3.6.1.2.1.80.1.2
DISMAN-PING-MIB::pingCtlTable = No Such Object available on this agent at this OID
注意：我已经看过这些帖子，对我来说没有运气。 add new mib master agent snmpget-no-such-object...和snmpget-returns-no-such-object...
更新2：
当我从服务器执行snmpwalk时，我得到：
root@snmp-server:# snmp-server:# snmpwalk -v 2c -c ncs -m DISMAN-PING-MIB 192.168.5.22 .1.3.6.1.2.1.80
DISMAN-PING-MIB::pingObjects.0 = INTEGER: 1

DISMAN-PING-MIB::pingCompliances.6.15.46.49.46.51.46.54.46.49.46.50.46.49.46.56.48 = INTEGER: 1

因此，当我按照snmpwalk的输出时，我得到：
root@snmp-server:# snmpget 192.168.5.22 DISMAN-PING-MIB::pingFullCompliance.15.46.49.46.51.46.54.46.49.46.50.46.49.46.56.48

我不明白为什么我有这么长的OID？ 什么是pingFullCompliance.15.46.49.46.51.46.54.46.49.46.50.46.49.46.56.48 ？我哪里错了？任何人都可以指出我正确的方向......谢谢你。
