0 CACTI监控100M以上流量求救,搜遍baidu、google

CACTI服务器和被监控得服务器都LINUX AS4 U4,原来安装好得CACTI能正常监控流量,最近被监控得服务器流量超过100M以上,大约在210M左右,CACTI的流量监控显示不正常,从网上搜遍了这个方面的文章,解决方案大同小异,但无法解决问题,恳请各位前辈帮忙下。以下是升级过程。
说明CACTI监控100M没问题,但超过了就不正常,网上给出的解决方案是必须升级SNMP

1. 解压安装SNMP(包括CACTI服务器和被监控服务器)
# tar zxvf net-snmp-5.4.1.tar.gz

2. 编译(包括CACTI服务器和被监控服务器)
# ./configure --enable-mfd-rewrites
编译最后会问你几个问题,第一个是默认选择的snmp协议类型,建议选2,其他的不知道就直接回车就行

3. 安装(包括CACTI服务器和被监控服务器)
# make && make install

安装完成后随便执行一个snmp程序如snmpbulkwalk,即可查看是否已经更新

4. 修改snmp配置文件(包括CACTI服务器和被监控服务器)
# vi /etc/snmp/snmpd.conf

--------------------------------------------------------------------------------
access  notConfigGroup ""      any       noauth    exact  systemvies none none
改成 access  notConfigGroup ""      any       noauth    exact  all none none

#view all    included  .1                               80
改成
view all    included  .1                               80

--------------------------------------------------------------------------------

5. 修改Cacti中相关配置
在Cacti管理页面中选择Console->Data Source
找到需要修改的端口(即流量大于100M的端口),修改Output Type ID 为 In/Out bits (64-bit counters)(原来为In/Out bits),修改Maximum Value 为 1000000000
修改Settings->aths,原安装时候snmp程序的路径,修改为新的snmp程序的安装路径确保使用的是net-snmp-5.4.1,新的snmp程序的安装路径在/usr/local/bin,拿snmpwalk举例,新的路径为/usr/local/bin/snmpwalk

做到这里问题就出来了一修改Output Type ID 为 In/Out bits (64-bit counters)就看不到流量,但改回原来的In/Out bits就能看到流量,但流量显示不对,CACTI中关于SNMP的路径和版本(SNMP2)的地方全部都检查过N*N次,确定路径没错版本没错
在CACTI服务器和被监控服务器执行
snmpd -version
都显示

NET-SNMP version:  5.4.1
Web:               http://www.net-snmp.org/
Email:             net-snmp-coders@lists.sourceforge.net
说明使用的都是新版本的SNMP,service snmpd restart也试过N次,但解决不了问题

# System contact information
#

# It is also possible to set the sysContact and sysLocation system
# variables through the snmpd.conf file:

syslocation Unknown (edit /etc/snmp/snmpd.conf)
syscontact Root <root@localhost> (configure /etc/snmp/snmp.local.conf)

# Example output of snmpwalk:
#   % snmpwalk -v 1 localhost -c public system
#   system.sysDescr.0 = "SunOS name sun4c"
#   system.sysObjectID.0 = OID: enterprises.ucdavis.ucdSnmpAgent.sunos4
#   system.sysUpTime.0 = Timeticks: (59563754 68 days, 22:32:55
#   system.sysContact.0 = "Me <me@somewhere.org>"
#   system.sysName.0 = "name"
#   system.sysLocation.0 = "Right here, right now."
#   system.sysServices.0 = 72

# Process checks.
#
#  The following are examples of how to use the agent to check for
#  processes running on the host.  The syntax looks something like:
#
#  proc NAME [MAX=0] [MIN=0]
#
#  NAME:  the name of the process to check for.  It must match
#         exactly (ie, http will not find httpd processes).
#  MAX:   the maximum number allowed to be running.  Defaults to 0.
#  MIN:   the minimum number to be running.  Defaults to 0.

#
#  Examples (commented out by default):
#

#  Make sure mountd is running
#proc mountd

#  Make sure there are no more than 4 ntalkds running, but 0 is ok too.
#proc ntalkd 4

#  Make sure at least one sendmail, but less than or equal to 10 are running.
#proc sendmail 10 1

#  A snmpwalk of the process mib tree would look something like this:
#
# % snmpwalk -v 1 localhost -c public .1.3.6.1.4.1.2021.2
# enterprises.ucdavis.procTable.prEntry.prIndex.1 = 1
# enterprises.ucdavis.procTable.prEntry.prIndex.2 = 2
# enterprises.ucdavis.procTable.prEntry.prIndex.3 = 3
# enterprises.ucdavis.procTable.prEntry.prNames.1 = "mountd"
# enterprises.ucdavis.procTable.prEntry.prNames.2 = "ntalkd"
# enterprises.ucdavis.procTable.prEntry.prNames.3 = "sendmail"
# enterprises.ucdavis.procTable.prEntry.prMin.1 = 0
# enterprises.ucdavis.procTable.prEntry.prMin.2 = 0
# enterprises.ucdavis.procTable.prEntry.prMin.3 = 1
# enterprises.ucdavis.procTable.prEntry.prMax.1 = 0
# enterprises.ucdavis.procTable.prEntry.prMax.2 = 4
# enterprises.ucdavis.procTable.prEntry.prMax.3 = 10
# enterprises.ucdavis.procTable.prEntry.prCount.1 = 0
# enterprises.ucdavis.procTable.prEntry.prCount.2 = 0
# enterprises.ucdavis.procTable.prEntry.prCount.3 = 1
# enterprises.ucdavis.procTable.prEntry.prErrorFlag.1 = 1
# enterprises.ucdavis.procTable.prEntry.prErrorFlag.2 = 0
# enterprises.ucdavis.procTable.prEntry.prErrorFlag.3 = 0
# enterprises.ucdavis.procTable.prEntry.prErrMessage.1 = "No mountd process running."
# enterprises.ucdavis.procTable.prEntry.prErrMessage.2 = ""
# enterprises.ucdavis.procTable.prEntry.prErrMessage.3 = ""
# enterprises.ucdavis.procTable.prEntry.prErrFix.1 = 0
# enterprises.ucdavis.procTable.prEntry.prErrFix.2 = 0
# enterprises.ucdavis.procTable.prEntry.prErrFix.3 = 0
#
#  Note that the errorFlag for mountd is set to 1 because one is not
#  running (in this case an rpc.mountd is, but thats not good enough),
#  and the ErrMessage tells you what's wrong.  The configuration
#  imposed in the snmpd.conf file is also shown.  
#
#  Special Case:  When the min and max numbers are both 0, it assumes
#  you want a max of infinity and a min of 1.
