距上次安裝CACTI&OPENNMS來作監控系統及網路

正好最近又有新的環境能試一下

來記一下重點…省下…下一次又要再回想過

環境是

HP A5500

FG200D

HP V1810-48G J9660A

SNMP部份

查看 SERVICE 有否啟動或安裝

SERVICE SNMP STATUS

排入開機

chkconfig --list |grep snmpd

chkconfig --level 345 snmpd on

service snmpd start

查詢部份

查詢使用指令 snmpwalk

snmpwalk -v 2c hostname -c XXX

其中

-v 目前使用 1或2c或3 指定版本號

-c後方 接snmp的Community Name

hostname 接目標主機ip或name或是localhost

正常設定完成會有一連串資訊

 SNMPv2-MIB::sysDescr.0 = STRING: Linux opennms 2.6.32-431.29.2.el6.x86_64 #1 SMP Tue Sep 9 21:36:05 UTC 2014 x86_64

SNMPv2-MIB::sysName.0 = STRING: opennms

SNMPv2-MIB::sysORID.3 = OID: SNMP-FRAMEWORK-MIB::snmpFrameworkMIBCompliance
SNMPv2-MIB::sysORID.4 = OID: SNMPv2-MIB::snmpMIB
SNMPv2-MIB::sysORID.5 = OID: TCP-MIB::tcpMIB
SNMPv2-MIB::sysORID.6 = OID: IP-MIB::ip
SNMPv2-MIB::sysORID.7 = OID: UDP-MIB::udpMIB
SNMPv2-MIB::sysORID.8 = OID: SNMP-VIEW-BASED-ACM-MIB::vacmBasicGroup
SNMPv2-MIB::sysORDescr.1 = STRING: The MIB for Message Processing and Dispatching

類似的一大串

再來是重要的除錯

取不到資訊的話

大部份是因為snmpd.conf尚未設定

請編輯

/etc/snmp/snmpd.conf

依自己的環境來設定

com2sec local localhost xxxxxx
com2sec localnet 192.168.0.0/16 xxxxxx

group MyROSystem v2c local
group MyROGroup v2c localnet

group MyRWGroup v2c local

view all included .1 80

access MyROGroup "" any noauth prefix all none none
access MyRWGroup "" any noauth prefix all all all

重點就只在於 xxxxxx 請改成自己的

而且目前我只開放 2c 所以在測試時 -v 後面加上2c

還有trap的部份功能也很強大…之後再弄…

cacti的部份安裝PHP Weathermap外掛之後

通常在畫完圖之後

有時會發現圖資沒有自動的更新

可以修改

 // figure out how long the refresh is, so that we get
                                        // through all the maps in exactly 5 minutes

                                        var period = <?php echo $refreshtime ?> * 1000;

                                        if(period == 0)
                                        {
                                                var period = 60000/j;
                                        }

                                        // our map-switching clock
                                        setInterval(wm_tick, period);
                                        // when to reload the whole page (with new map data)
                                        setTimeout( wm_reload ,60000);

cacti 沒有流量圖產生

通常是存放繪圖的資料夾沒有權限

請修改rra資料夾權限(流量部份如果是nan但有圖的話(.rrd)，那就稍等片刻即可)

查rra產量部份

使用指令，替換自己的 .rrd名稱

cat /opt/opennms/bin/opennms | egrep 'ADDITIONAL_MANAGER_OPTIONS='

ADDITIONAL_MANAGER_OPTIONS="-Duser.language=en"
