Collectd SNMP 插件无法找到 MIB

  • 772

使用 Collectd 通过 snmp 插件轮询 Cisco 设备。我将所需的 Cisco mib（CISCO-MEMORY-POOL-MIB 和 CISCO-PROCESS-MIB）加载到 net-snmp 中，并且 snmpwalk 可以很好地看到它们。

但是当我尝试将它们添加到 collectd 时，我在重新启动 collectd 服务时收到以下错误：

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">
      Type "if_octets"
      Table true
      Instance "IF-MIB::ifAlias"

  </Data>
  <Data "if_errors">

    Instance "IF-MIB::ifAlias"
    Values "IF-MIB::ifInErrors" "IF-MIB::ifOutErrors"
  </Data>

    Type "memory_free"

    Values  "CISCO-MEMORY-POOL-MIB::ciscoMemoryPoolFree"
  </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>

我在这里想念什么？我也尝试过使用 OID 地址而不是名称，但我也一无所获。

snmp collectd net-snmp

    玩弄一些设置，我取得了一些成功。

    如果我将类型更改为“gauge”并将表更改为“false”，则 CISCO-MEMORY-POOL PoolFree/Used 可以工作。说得通。但 CISCO-PROCESS-MIB cpu 以百分比形式返回。还是拿不到那个。

    以下是 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>

    仍然无法弄清楚 MIB / OID 名称问题。
