RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Fixed In Version: virt-who-0.17-1.el7
Doc Type: Bug Fix
Doc Text:
Previously, virt-who was very verbose when writing to its log file. As a result, the log file grew very quickly, especially in large environments. Now, virt-who logs significantly less information in non-debug mode, and the log file thus grows slower.

Comment 18 Radek Novacek 2016-09-29 05:43:00 UTC 
Mithun,

virt-who logs to the /var/log/rhsm/rhsm.log file. If something in /var/log/foreman/ is growing too fast, I would guess it is a different issue. But it would be best if someone can analyze the big file for log entries that are filling it. Only that way we can be sure what is the problem there.

Radek,

virt-who submits data to Candlepin via Foreman/Katello.
Sadly Foreman will log the whole request (incl the full JSON) to production log. So thats the reason for foreman/production.log to grow.
Same happens in Candlepin, see c11 for a workaround.
Comment 21 Radek Novacek 2016-10-06 06:10:01 UTC 
Mithun,

does the customer use filter_hosts/exclude_hosts options to run virt-who only against systems that do run Red Hat servers? If not, you might suggest it to them, I think it would both reduce the load and generate less logs.
