Package: snmpd Version: 5.4.3-dfsg-2.4 Severity: normal Tags: upstream I found a strange CPU Raw usage reports after the upgrade from 5.4.3-dfsg-2.2 to 5.4.3-dfsg-2.4.
Here are 2 SNMP report from 2 different system with 4 cores each: Good SNMP # dpkg -l | grep snmp ii libsnmp-base 5.4.3~dfsg-2.2 SNMP (Simple Network Management Protocol) MIBs and documentation ii libsnmp15 5.4.3~dfsg-2.2 SNMP (Simple Network Management Protocol) library ii snmp 5.4.3~dfsg-2.2 SNMP (Simple Network Management Protocol) applications ii snmpd 5.4.3~dfsg-2.2 SNMP (Simple Network Management Protocol) agents # snmpd -v NET-SNMP version: 5.4.3 Web: http://www.net-snmp.org/ Email: [email protected] CpuRaw output $ IP=A.A.A.185; COM=YYYY; snmpwalk -v2c -c$COM $IP .1.3.6.1.4.1.2021.11 | grep "CpuRaw"; echo "wait 10 seconds"; sleep 10; snmpwalk -v2c -c$COM $IP ..1.3.6.1.4.1.2021.11 | grep "CpuRaw" UCD-SNMP-MIB::ssCpuRawUser.0 = Counter32: 11598955 UCD-SNMP-MIB::ssCpuRawNice.0 = Counter32: 2005 UCD-SNMP-MIB::ssCpuRawSystem.0 = Counter32: 1465887 UCD-SNMP-MIB::ssCpuRawIdle.0 = Counter32: 1732454780 UCD-SNMP-MIB::ssCpuRawWait.0 = Counter32: 917382 UCD-SNMP-MIB::ssCpuRawKernel.0 = Counter32: 0 UCD-SNMP-MIB::ssCpuRawInterrupt.0 = Counter32: 418 UCD-SNMP-MIB::ssCpuRawSoftIRQ.0 = Counter32: 15281275 wait 10 seconds UCD-SNMP-MIB::ssCpuRawUser.0 = Counter32: 11599129 UCD-SNMP-MIB::ssCpuRawNice.0 = Counter32: 2005 UCD-SNMP-MIB::ssCpuRawSystem.0 = Counter32: 1465888 UCD-SNMP-MIB::ssCpuRawIdle.0 = Counter32: 1732458577 UCD-SNMP-MIB::ssCpuRawWait.0 = Counter32: 917386 UCD-SNMP-MIB::ssCpuRawKernel.0 = Counter32: 0 UCD-SNMP-MIB::ssCpuRawInterrupt.0 = Counter32: 418 UCD-SNMP-MIB::ssCpuRawSoftIRQ.0 = Counter32: 15281301 ------------------------ Results: UCD-SNMP-MIB::ssCpuRawUser.0 = 174 UCD-SNMP-MIB::ssCpuRawNice.0 = 0 UCD-SNMP-MIB::ssCpuRawSystem.0 = 1 UCD-SNMP-MIB::ssCpuRawIdle.0 = 3797 UCD-SNMP-MIB::ssCpuRawWait.0 = 4 UCD-SNMP-MIB::ssCpuRawKernel.0 = 0 UCD-SNMP-MIB::ssCpuRawInterrupt.0 = 0 UCD-SNMP-MIB::ssCpuRawSoftIRQ.0 = 26 Total = 4002 => 400.20% for 4 cores 400.20% is perfect for 4 cores system.
