hi,


THE FOLLOWING IS FROM A REMOTE LINUX SERVER
-----------------------------------------------------
snmpwalk -v 1 localhost public .1.3.6.1.4.1.2021.11

enterprises.ucdavis.systemStats.ssIndex.1 = 1
enterprises.ucdavis.systemStats.ssErrorName.1 = "systemStats"
enterprises.ucdavis.systemStats.ssSwapIn.1 = 76720
enterprises.ucdavis.systemStats.ssSwapOut.1 = 9010
enterprises.ucdavis.systemStats.ssIOSent.1 = 163660298
enterprises.ucdavis.systemStats.ssIOReceive.1 = 93740523
enterprises.ucdavis.systemStats.ssSysInterrupts.1 = 636106992
enterprises.ucdavis.systemStats.ssSysContext.1 = 1677511593
enterprises.ucdavis.systemStats.ssCpuUser.1 = 93725826
enterprises.ucdavis.systemStats.ssCpuSystem.1 = 25591686
enterprises.ucdavis.systemStats.ssCpuIdle.1 = 315601466      
-------------------------------------------------------------

THE FOLLOWING IS ON FREEBSD SERVER
-----------------------------------------------------------
$ snmpwalk -v 1 localhost public .1.3.6.1.4.1.2021.11
enterprises.ucdavis.systemStats.ssIndex.0 = 1
enterprises.ucdavis.systemStats.ssErrorName.0 = systemStats
enterprises.ucdavis.systemStats.ssSwapIn.0 = 1
enterprises.ucdavis.systemStats.ssSwapOut.0 = 0
enterprises.ucdavis.systemStats.ssSysInterrupts.0 = 233
enterprises.ucdavis.systemStats.ssSysContext.0 = 8
enterprises.ucdavis.systemStats.ssCpuUser.0 = 1
enterprises.ucdavis.systemStats.ssCpuSystem.0 = 1
enterprises.ucdavis.systemStats.ssCpuIdle.0 = 97      
---------------------------------------------------------
1)

Now my query is the ssCpuIdle.1 value in the remote linux system
is greater than the one which i get in freebsd.I think this
is due to the different in the measurement scale used by snmp.
Is there any way where i can use the same measurement scale 
to get a high out in freebsd too.

2)
What is the OID for enterprises.ucdavis.systemStats.ssIOSent in freebsd 

3)
I am using the snmp mib oids in mrtg.but the mrtg log file for that
target is some thing like this.



I would like to monitor the performance of cpu idle.
Target[load_i]:
.1.3.6.1.4.1.2021.11.11.0&.1.3.6.1.4.1.2021.11.11.0:public at localhost
gives me a blank graph.
and the log file looks like this.

965660752 97 97
965660752 0 0 0 0

I am getting a blank graph because of null values.



Can any one please help me.

Regards 
siva.
