透過SNMP Query Index協助管理 資源流量圖表自動產出
Cacti監控報表圖多不愁 批次抓取設備資料繪製
丁光立

因為想多學一點 Cacti 的技巧,所以參考了上述文章,一些觀念,寫成這個小筆記供需要
的人參考,但本文會著重於 Linux (CentOS) 的 snmp 實用指令簡介及運用與
 snmp.conf 的撰寫參考等等.建議在閱讀本文之前,可看參考上述基本門,強化
 snmp 基本觀念.


(1) linux (  CentOS ) snmpd.conf
詳細設定可參考
http://net-snmp.sourceforge.net/docs/man/snmpd.conf.html

為方便使用可參考如下設定,請抄改成個人的使用環境配置.

[root@bbb /]# cat /etc/snmp/snmpd.conf

rocommunity public

#這一行是宣告 MIB 檔的目錄.
#MIBDIRS /usr/share/snmp/mibs:/usr/share/snmp/private-mibs
#這一行是宣告載入所有的 MIB 檔
#MIBS all

#宣告使用 CHECK-R77-MIB及CISCO-QOS-PIB-MIB
mibs +CHECK-R77-MIB:CISCO-QOS-PIB-MIB
#宣告使用 CISCO-MEMORY-POOL-MIB
mibs +CISCO-MEMORY-POOL-MIB

#另一種宣告方式

mibfile /usr/share/snmp/mibs/CHECK-R77-MIB.txt

#其它資訊

sysLocation vlab
sysContact wwww.vlab.com.tw
sysName Cacti

# 其它參考資訊如下 URL
# http://www.net-snmp.org/FAQ.html#How_do_I_add_a_MIB_
# 系統預設的 mibs 的目錄為 /usr/share/snmp/mibs 可將自行下載的 mib 檔放置於此目錄內.

(2)使用 export MIBS , 以 CISCO-MEMORY-POOL-MIB 為例


[root@bbb /]# MIBS=+CISCO-MEMORY-POOL-MIB
[root@bbb /]# export MIBS


[root@bbb /]#   snmpwalk -c public -v2c     192.168.111.158   .1.3.6.1.4.1.9.9.48
CISCO-MEMORY-POOL-MIB::ciscoMemoryPoolName.1 = STRING: Processor
CISCO-MEMORY-POOL-MIB::ciscoMemoryPoolName.14 = STRING: lsmpi_io
CISCO-MEMORY-POOL-MIB::ciscoMemoryPoolAlternate.1 = INTEGER: 0
CISCO-MEMORY-POOL-MIB::ciscoMemoryPoolAlternate.14 = INTEGER: 0
CISCO-MEMORY-POOL-MIB::ciscoMemoryPoolValid.1 = INTEGER: true(1)
CISCO-MEMORY-POOL-MIB::ciscoMemoryPoolValid.14 = INTEGER: true(1)

CISCO-MEMORY-POOL-MIB::ciscoMemoryPoolUsed.14 = Gauge32: 6294296 bytes
CISCO-MEMORY-POOL-MIB::ciscoMemoryPoolFree.1 = Gauge32: 2037176144 bytes
CISCO-MEMORY-POOL-MIB::ciscoMemoryPoolFree.14 = Gauge32: 832 bytes
CISCO-MEMORY-POOL-MIB::ciscoMemoryPoolLargestFree.1 = Gauge32: 1332474908 bytes
CISCO-MEMORY-POOL-MIB::ciscoMemoryPoolLargestFree.14 = Gauge32: 412 bytes


(3) 未使用 CISCO-MEMORY-POOL-MIB


[root@bbb /]#  snmpwalk -c public -v2c     192.168.111.158   .1.3.6.1.4.1.9.9.48
SNMPv2-SMI::enterprises.9.9.48.1.1.1.2.1 = STRING: "Processor"
SNMPv2-SMI::enterprises.9.9.48.1.1.1.2.14 = STRING: "lsmpi_io"
SNMPv2-SMI::enterprises.9.9.48.1.1.1.3.1 = INTEGER: 0
SNMPv2-SMI::enterprises.9.9.48.1.1.1.3.14 = INTEGER: 0
SNMPv2-SMI::enterprises.9.9.48.1.1.1.4.1 = INTEGER: 1
SNMPv2-SMI::enterprises.9.9.48.1.1.1.4.14 = INTEGER: 1
SNMPv2-SMI::enterprises.9.9.48.1.1.1.5.1 = Gauge32: 195206240

SNMPv2-SMI::enterprises.9.9.48.1.1.1.7.1 = Gauge32: 1332474908
SNMPv2-SMI::enterprises.9.9.48.1.1.1.7.14 = Gauge32: 412

一般而言,有導入使用 MIB 檔會比較方便閱讀與理解.


(4)透過 load mib 參數

CISCO-MEMORY-POOL-MIB::ciscoMemoryPoolValid.14 = INTEGER: true(1)
CISCO-MEMORY-POOL-MIB::ciscoMemoryPoolUsed.1 = Gauge32: 195216024 bytes
CISCO-MEMORY-POOL-MIB::ciscoMemoryPoolUsed.14 = Gauge32: 6294296 bytes
CISCO-MEMORY-POOL-MIB::ciscoMemoryPoolFree.1 = Gauge32: 2037166360 bytes
CISCO-MEMORY-POOL-MIB::ciscoMemoryPoolFree.14 = Gauge32: 832 bytes
CISCO-MEMORY-POOL-MIB::ciscoMemoryPoolLargestFree.1 = Gauge32: 1332474908 bytes
CISCO-MEMORY-POOL-MIB::ciscoMemoryPoolLargestFree.14 = Gauge32: 412 bytes




[root@bbb /]# snmpwalk -c public -v2c  -m CISCO-MEMORY-POOL-MIB   192.168.111.158   .1.3.6.1.4.1.9.9.48

CISCO-MEMORY-POOL-MIB::ciscoMemoryPoolName.14 = STRING: lsmpi_io
CISCO-MEMORY-POOL-MIB::ciscoMemoryPoolAlternate.1 = INTEGER: 0
CISCO-MEMORY-POOL-MIB::ciscoMemoryPoolAlternate.14 = INTEGER: 0
CISCO-MEMORY-POOL-MIB::ciscoMemoryPoolValid.1 = INTEGER: true(1)
CISCO-MEMORY-POOL-MIB::ciscoMemoryPoolValid.14 = INTEGER: true(1)
CISCO-MEMORY-POOL-MIB::ciscoMemoryPoolUsed.1 = Gauge32: 195216016 bytes
CISCO-MEMORY-POOL-MIB::ciscoMemoryPoolUsed.14 = Gauge32: 6294296 bytes

CISCO-MEMORY-POOL-MIB::ciscoMemoryPoolValid.1 = INTEGER: true(1)
CISCO-MEMORY-POOL-MIB::ciscoMemoryPoolValid.14 = INTEGER: true(1)
CISCO-MEMORY-POOL-MIB::ciscoMemoryPoolUsed.1 = Gauge32: 195210248 bytes

(8) 實戰透過 snmpwalk 取得 ciscoMemoryPool 資訊

可參考http://www.oidview.com/mibs/9/CISCO-MEMORY-POOL-MIB.html

以   Processor Memory Pool 及 lsmpi_io Memory Pool 為例

[root@bbb /]# snmptranslate  -IR -Onf ciscoMemoryPoolName
.iso.org.dod.internet.private.enterprises.cisco.ciscoMgmt.ciscoMemoryPoolMIB.ciscoMemoryPoolObjects.ciscoMemoryPoolTable.ciscoMemoryPoolEntry.ciscoMemoryPoolName




[root@bbb /]# snmptranslate -m CISCO-MEMORY-POOL-MIB  -IR -Onf ciscoMemoryPoolName
.iso.org.dod.internet.private.enterprises.cisco.ciscoMgmt.ciscoMemoryPoolMIB.ciscoMemoryPoolObjects.ciscoMemoryPoolTable.ciscoMemoryPoolEntry.ciscoMemoryPoolName

[root@bbb /]# snmptranslate -m CISCO-MEMORY-POOL-MIB  -IR -On ciscoMemoryPoolName

Processor MemoryPool

lsmpi_io MemoryPool

對照 Cicso 設備下指令顯示的資訊,看到的資訊應該跟 snmpget 到的資訊差不多才是
