ucd/net - CPU Usage: shows ticks and not percentage

[shane]

Hello all,

I have configured the CPU graph for a net-snmp host. However the graph is showing some huge numbers (in millions) instead of showing percentages. The snmpwalk output looks like:

> snmpwalk -v 1 myhost.com -c public .1.3.6.1.4.1.2021.11.51.0
UCD-SNMP-MIB::ssCpuRawNice.0 = Counter32: 16686

>snmpwalk -v 1 myhost.com -c public .1.3.6.1.4.1.2021.11.52.0
UCD-SNMP-MIB::ssCpuRawSystem.0 = Counter32: 16703849

> snmpwalk -v 1 myhost.com -c public .1.3.6.1.4.1.2021.11.50.0
UCD-SNMP-MIB::ssCpuRawUser.0 = Counter32: 33400673

I am not sure on which side the problem is: Does net-snmp have to be configured to send out percentages instead of ticks? Or does cacti graph template need to be modified to show percentages instead of ticks?

The default OID for cpu_user seems to be .1.3.6.1.4.1.2021.11.50.0. Should we use the OID: .1.3.6.1.4.1.2021.11.9.0 instead?

Thanks,
