收集SNMP插件找不到MIB

Question

使用plugin通过snmp插件轮询Cisco设备。我有必要的思科MIB(思科-内存池-MIB和思科-进程-MIB)加载到网络-snmp和snmpwalk可以看到他们很好。

但是，当我试图将它们添加到get中时，在重新启动get服务时会出现以下错误：

Cannot find module (CISCO-MEMORY-POOL-MIB): At line 0 in (none)
Cannot find module (CISCO-PROCESS-MIB): At line 0 in (none)

日志文件显示：

这是我的collectd.conf的snmp部分

<Plugin snmp>
  <Data "SysInfo">
      Type "counter"
      Table false
      Instance "sysName"
      Values  "SNMPv2-MIB::sysName"
  </Data>
  <Data "uptime">
     Type "uptime"
     Table false
     Instance "Uptime"
     scale 0.01
    Values  "DISMAN-EVENT-MIB::sysUpTimeInstance"
  </Data>
  <Data "if_octets">

      Table true
      Instance "IF-MIB::ifAlias"
      Values "IF-MIB::ifHCInOctets" "IF-MIB::ifHCOutOctets"
  </Data>
  <Data "if_errors">

  </Data>
  <Data "memory_used">
    Type "memory_used"
    Table true
    Instance "CISCO-MEMORY-POOL-MIB::ciscoMemoryPoolName"
    Values "CISCO-MEMORY-POOL-MIB::ciscoMemoryPoolUsed"
  </Data>
  <Data "cisco_cpu">
      Type "cisco_cpu"
      Table true
      Values "CISCO-PROCESS-MIB::cpmCPUTotal5secRev" "CISCO-PROCESS-MIB::cpmCPUTotal1minRev" "CISCO-PROCESS-MIB::cpmCPUTotal5minRev"
  </Data>    

我在这里错过了什么？我也尝试使用OID地址而不是名字，但我也什么也没有得到。

玩一些设置，我得到了一些成功。

思科-内存池池自由/使用，如果我改变类型为“规范”和表为“假”。合乎道理。但思科-进程-MIB cpu返回的百分比，它看上去。还是拿不到那个。

下面是snmpwalk返回OID的方式：

[root@NMS-srv2 ~]# snmpwalk -v 2c -c rbhome spine1 CISCO-MEMORY-POOL-MIB::ciscoMemoryPoolFree
CISCO-MEMORY-POOL-MIB::ciscoMemoryPoolFree.1 = Gauge32: 564215448 bytes

[root@NMS-srv2 ~]# snmpwalk -v 2c -c rbhome spine1 CISCO-MEMORY-POOL-MIB::ciscoMemoryPoolUsed
CISCO-MEMORY-POOL-MIB::ciscoMemoryPoolUsed.1 = Gauge32: 249119560 bytes

[root@NMS-srv2 ~]# snmpwalk -v 2c -c rbhome spine1 CISCO-PROCESS-MIB::cpmCPUTotal1minRev
CISCO-PROCESS-MIB::cpmCPUTotal1minRev.7 = Gauge32: 1 percent

这是现在的配置。

 <Data "memory_used">
    Type "gauge"
    Table false
    Instance "memory_used"
    Values "1.3.6.1.4.1.9.9.48.1.1.1.5.1"
  </Data>
  <Data "cisco_cpu">
      Type "gauge"
      Table false
      Instance "cpu_used_min"
      Values "1.3.6.1.4.1.9.9.109.1.1.1.1.7.7" "1.3.6.1.4.1.9.9.109.1.1.1.1.8.7"
  </Data>  

仍然无法解决MIB / OID名称问题。
