[CentOS] yum history list

Hi List,

I have several workstations all with exactly the same OS versions,
kernels + yum versions;

CentOS Linux release 7.2.1511 (Core)
kernel.x86_64		3.10.0-327.28.3.el7
yum.noarch              3.4.3-132.el7.centos.0.1

running a 'yum history list' command produces different outputs on some
workstations, I haven't changed any yum configurations.

Workstation A:
yum history list
Loaded plugins: fastestmirror, langpacks
ID     | Login user               | Date and time    | Action(s)      |
Altered


Workstation B:
yum history list
Loaded plugins: fastestmirror, langpacks
ID     | Command line             | Date and time    | Action(s)      |
Altered


Any clue as to why I have different fields being output?

I see in the yum manual:
In  "history  list" you can change the behaviour of the 2nd column via
the configuration option history_list_view.

But I'm unsure how I can adjust the columns.

Any clues would be much appreciated,

Thanks,

Michael
