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::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.9.9.48.1.1.1.7.1 = 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

[root@bbb/]# snmpwalk -c public -v2c 192.168.111.158 CISCO-MEMORY-POOL-MIB::ciscoMemoryPoolMIB
CISCO-MEMORY-POOL-MIB::ciscoMemoryPoolName.1 = STRING: Processor

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: 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

或

[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.1 = STRING: Processor
CISCO-MEMORY-POOL-MIB::ciscoMemoryPoolName.14 = STRING: lsmpi_io

CISCO-MEMORY-POOL-MIB::ciscoMemoryPoolLargestFree.14 = Gauge32: 412 bytes
