Description Ala Hino 2017-11-05 12:59:26 UTC

Description of problem:
ovirt-log-collector collects logs from all hosts, which makes its output too big to handle. Specifying a list of hypervisors by name is tedious and error-prone. People tend to be using --no-hypervisor and miss the purpose.

This RFE is about adding a midway --one-hypervisor-per-cluster. When supplied to the script, the script would choose one host per cluster, and collect its logs. The current SPM and the current host of a self-hosted-engine should be included as well.

See BZ 1490447

Hi Ala,

Thanks for raising this bug. To which versions does this apply, and what is the documentation requirement? It sounds like the code is still being worked on here.

Hi Lucy,

The change already merged to master branch and will be applied to 3.6 (cloned BZ 1512307) and 4.1 (cloned BZ 1512308).

Basically, we have to document the new option, based on the description in this bug.
