[Pkg-net-snmp-devel] Bug#815580: jessie's snmpd hrSystemProcesses OID reports a wrong number of processes

[Juan David Abreo]

Package: snmpd
Version: 5.7.2.1+dfsg-1
Severity: normal

Dear Maintainer,

Fresh install Jessie's snmp's OIDs for hrSystemProcesses are reporting a lower number of processes,
looks like only counting user processes and leaving out kernel ones. Tested on v.3 and v.4 kernels for jessie.


  myserver:~$snmpwalk -v 2c -c mycomunity 127.0.0.1 hrsystemprocesses
HOST-RESOURCES-MIB::hrSystemProcesses.0 = Gauge32: 66

  myserver ~]# ps aux|wc -l
405

  myserver ~]# ps aux|egrep -v '\[*\]'|wc -l
66
