Hi David,

Could you please:

- Share sosreport-LogCollector-20180202144325.tar.xz ?
- Test against ovirt-log-collector-4.2.3-1.el7ev ?
  Looks like you are using an old version (ovirt-log-collector-analyzer-4.2.0-1.el7ev.noarch)

Comment 3 David Necpal 2018-02-20 11:42:35 UTC

Hello Douglas, 

I don't have this report, because engine was updated. 

I tried test now with:
ovirt-log-collector-analyzer-4.2.3-1.el7ev.noarch

and sosreport from:
ovirt-log-collector-4.1.7-1.el7ev.noarch

the result is:
Missing almost all of information. This report contains only 
    1. Sosreport
    2. Pre-upgrade checks


I will share sosreport and analyzer report.

Comment 6 David Necpal 2018-02-23 18:31:41 UTC

Verified on version:
ovirt-log-collector-4.1.8-1.el7ev.noarch
ovirt-log-collector-analyzer-4.2.4-2.el7ev.noarch
