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.

Enabling JSON output in nft monitor should be possible via '-j' flag or at least 'nft monitor json', not 'nft monitor vm json' as it is now in RHEL8.

Upstream, there is 'nft monitor json'. Ideally '-j' should be respected and 'json' parameter be deprecated.

Fix sent upstream: https://marc.info/?l=netfilter-devel&m=156036046227680&w=2

    monitor: Accept -j flag
    
    Make 'nft -j monitor' equal to 'nft monitor json' and change
    documentation to use only the first variant since that is more intuitive
    and also consistent with other commands.
    
    While being at it, drop references to XML from monitor section - it was
    never supported.

Implicitly resolved by rebase.

Tomas,

Can we cover for this in RHEL-8.2.0? For testing, it should suffice to make sure that 'nft -j monitor' will print JSON output.

Cheers, Phil
