Snmp
Net-SNMP 中缺少 CPU 核心
OEL
我有一台執行( ) 6.4的雙 Intel Xeon E5-2667 CPU(6 核 + HT)的伺服器,RHEL
由於某種原因,對它的 snmp 查詢顯示只有 1 個 CPU 的核心。這是輸出
sensors
命令。[root@host log]# sensors coretemp-isa-0000 Adapter: ISA adapter Physical id 0: +56.0°C (high = +96.0°C, crit = +102.0°C) Core 0: +55.0°C (high = +96.0°C, crit = +102.0°C) Core 1: +50.0°C (high = +96.0°C, crit = +102.0°C) Core 2: +52.0°C (high = +96.0°C, crit = +102.0°C) Core 3: +55.0°C (high = +96.0°C, crit = +102.0°C) Core 4: +52.0°C (high = +96.0°C, crit = +102.0°C) Core 5: +56.0°C (high = +96.0°C, crit = +102.0°C) coretemp-isa-0001 Adapter: ISA adapter Physical id 1: +43.0°C (high = +96.0°C, crit = +102.0°C) Core 0: +43.0°C (high = +96.0°C, crit = +102.0°C) Core 1: +41.0°C (high = +96.0°C, crit = +102.0°C) Core 2: +42.0°C (high = +96.0°C, crit = +102.0°C) Core 3: +41.0°C (high = +96.0°C, crit = +102.0°C) Core 4: +40.0°C (high = +96.0°C, crit = +102.0°C) Core 5: +41.0°C (high = +96.0°C, crit = +102.0°C)
my
/etc/snmp/snmpd.conf
具有以下行以允許完全訪問:view all included .1 80
然而,當我對該伺服器進行 snmpwalk 時,會發生以下情況:
[root@host log]# snmpwalk -c public -v 2c localhost sensor LM-SENSORS-MIB::lmTempSensorsIndex.1 = INTEGER: 1 LM-SENSORS-MIB::lmTempSensorsIndex.2 = INTEGER: 2 LM-SENSORS-MIB::lmTempSensorsIndex.3 = INTEGER: 3 LM-SENSORS-MIB::lmTempSensorsIndex.4 = INTEGER: 4 LM-SENSORS-MIB::lmTempSensorsIndex.5 = INTEGER: 5 LM-SENSORS-MIB::lmTempSensorsIndex.6 = INTEGER: 6 LM-SENSORS-MIB::lmTempSensorsIndex.7 = INTEGER: 7 LM-SENSORS-MIB::lmTempSensorsIndex.8 = INTEGER: 8 LM-SENSORS-MIB::lmTempSensorsDevice.1 = STRING: Physical id 0 LM-SENSORS-MIB::lmTempSensorsDevice.2 = STRING: Core 0 LM-SENSORS-MIB::lmTempSensorsDevice.3 = STRING: Core 1 LM-SENSORS-MIB::lmTempSensorsDevice.4 = STRING: Core 2 LM-SENSORS-MIB::lmTempSensorsDevice.5 = STRING: Core 3 LM-SENSORS-MIB::lmTempSensorsDevice.6 = STRING: Core 4 LM-SENSORS-MIB::lmTempSensorsDevice.7 = STRING: Core 5 LM-SENSORS-MIB::lmTempSensorsDevice.8 = STRING: Physical id 1 LM-SENSORS-MIB::lmTempSensorsValue.1 = Gauge32: 60000 LM-SENSORS-MIB::lmTempSensorsValue.2 = Gauge32: 44000 LM-SENSORS-MIB::lmTempSensorsValue.3 = Gauge32: 42000 LM-SENSORS-MIB::lmTempSensorsValue.4 = Gauge32: 42000 LM-SENSORS-MIB::lmTempSensorsValue.5 = Gauge32: 42000 LM-SENSORS-MIB::lmTempSensorsValue.6 = Gauge32: 41000 LM-SENSORS-MIB::lmTempSensorsValue.7 = Gauge32: 41000 LM-SENSORS-MIB::lmTempSensorsValue.8 = Gauge32: 44000
如何讓 snmp 報告所有 CPU 上核心的溫度?
似乎有些不對勁,因為您有這條線:
LM-SENSORS-MIB::lmTempSensorsDevice.8 = STRING: Physical id 1
但之後什麼也沒有,好像只有 8 個感測器插槽。有一個雙 Intel Xeon E5-2670(8 核)的錯誤報告,其中最後一個 Device 行是這樣的:
LM-SENSORS-MIB::lmTempSensorsDevice.10 = STRING: Physical id 1
所以那裡有 10 個插槽,同樣只有一個處理器。
有一些 Ubuntu 指令成功顯示了 20 個插槽(那裡沒有“物理 id”行),儘管使用完全不同的處理器並使用 miscSensors 類別。他們在那裡說“根據 lm-sensors 安裝頁面,需要 Net-SNMP 5.5 或更高版本”,這是 RedHat 6.4 上的版本。
在任何情況下,您都可以嘗試升級 Net-SNMP 並查看是否可以解決問題。但也許這確實是 MIB 和特定處理器系列的問題,在這種情況下,需要解決該錯誤。
