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)

这是我的 collectd.conf 的 snmp 部分

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。
