Description Henning Sackewitz 2013-06-13 07:45:27 EDT

+++ This bug was initially created as a clone of Bug #974071 +++

The values for UserModeTime and KernelModeTime in CIM class Linux_UnixProcess are incorrectly calculated.

OSBase_UnixProcess.c:

231 if ( (fpstat=fopen(cmd,"r")) != NULL ) {
232 fscanf(fpstat,"%s %s %s %s %s %s %s %s %s %s %s %s %s %s "
233 "%lld %lld %s %s %s %s %s %ld",
234 &umtime,&kmtime,&ctime );
235 fclose(fpstat);
236 (sptr)->kmtime = kmtime10;
237 (sptr)->umtime = umtime*10;

The code is scanning fields 15 and 16 from /proc/[pid]/stat but it should use fields 14 and 15 on current Linux kernels as documented in
/usr/src/linux/Documentation/filesystems/proc.txt.

As a result, KernelModeTime is used for UserModeTime, and Child User Time for KernelModeTime.

See https://sourceforge.net/p/sblim/bugs/2644/ for upstream bug fix.

Removed RFE from title since this is really a bugfix and not a feature request

Comment 2 Luca Miccini 2014-01-28 10:34:03 EST

On behalf of SAP LinuxLab I confirm that there will be the necessary commitment to test the new packages.
