Description Chuck Mead 2007-08-28 20:13:44 UTC 
Description of problem:

The idle counter in /proc/stat (5th column - 26752194897 in this case) is much
larger than a 32 bit number. The snmpd agent is doing a sscanf %lu on this and
as such returns 4294967295. This has been fixed two years ago and applies to
all ssRawCPU counters and others. The fix is basically %llu on the values.



Version-Release number of selected component (if applicable):
net-snmp-5.1.2-11.EL4.10.0.1


How reproducible:

snmpwalk -v1 -cpublic localhost ssCpuRawIdle.0;head -n1 /proc/stat

Steps to Reproduce:
1. snmpwalk -v1 -cpublic localhost ssCpuRawIdle.0;head -n1 /proc/stat
2.
3.
  
Actual results:
UCD-SNMP-MIB::ssCpuRawIdle.0 = Counter32: 4294967295
cpu  259515841 311084 138251888 26752194897 27766490 936245 0


Expected results:
The Mib output from line #1 should have rolled over... it never does.

Additional info:

This bug was reported 2 years ago on sf.net and I believe has already been fixed
upstream.
