Collectd SNMP 插件无法找到 MIB

使用 Collectd 通过 snmp 插件轮询 Cisco 设备。我已将所需的 Cisco mib（CISCO-MEMORY-POOL-MIB 和 CISCO-PROCESS-MIB）加载到 net-snmp 中，snmpwalk 可以正常查看它们。

但是当我尝试将它们添加到 collectd 中时，重新启动 collectd 服务时出现以下错误：

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>

     Type "uptime"
     Table false
     Instance "Uptime"
     scale 0.01

    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>

我这里遗漏了什么？我也尝试过使用 OID 地址代替名称，但也没有得到任何结果。

答案1

尝试一些设置并取得一些成功。

如果我将类型更改为“gauge”并将表更改为“false”，CISCO-MEMORY-POOL PoolFree/Used 就会起作用。这很合理。但 CISCO-PROCESS-MIB cpu 返回的似乎是百分比。仍然无法获得那个。

snmpwalk 返回 OID 的方式如下：

[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

这是当前的配置。

 <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>

仍然无法弄清楚 MIB / OID 名称问题。
