Are these config reports from Puppet in a default Foreman installation, or another config management plugin/tool? Perhaps last_report isn't updated if a different importer's in use.

All reports for all servers in foreman are from a seperate Puppetmaster with smartproxy and puppet reporter installed. Only some nodes has these lacking last_report.

Could you tail -f /var/log/foreman/production.log while running a Puppet agent on one of the affected hosts, and attach the resulting log? Perhaps an error is occurring during the report upload.

Is this enough?

Yeah, it appears to be successful - the update should have happened before the last log message (though without SQL logs I can't tell if it did).

Regarding the earlier comment 2, is the record shown definitely the same as the host you looked up in the rake console command? The timestamps look off - the updated_at is 2016-12-30, but the last_report is 2017-01-02. It appears to me that you have multiple, perhaps differently named hosts.

Check with Host.find_by_name('ceph-008.X').id or similar to check the record IDs are the same.

2016-12-30 is the day i installed Foreman and setup Puppet reports / facts push.

Actually they have different id's so these are just duplicates. Thats strange but i guess something has happened while setting up the puppet integration,

Deleted the duplicated failed hosts. They havent turned up yet.

Guess its just some glitch in the matrix while configuring Foreman/Puppet.
