Have report_* vars filled automatically

Folks,

I have a feature request with me but before opening a new feature request on our Jira, I would like to check with you guys the feasibility of that. This is regarding the value of report_host, to have this being filled automatically with the value set for host’s hostname. If the DBA would like to override that name set on the host’s hostname, the DBA need to set it on MariaDB Server’s configuration file.

The justification of this is that, most of the time we face giant topologies with lots of masters, intermediate masters and slaves of the slaves and it makes it very difficult to map out the customer’s topology. In this case, if we have the report_host being fed automatically, we can go on the master and just get a list of slaves out of SHOW SLAVE HOSTS.

The way we to do it currently requires to set the value you want for the report_* vars on the configuration file and restart the instance, most of the times, the customer does not want to do that.

The same effect of feeding automatically vars can be used to set

report_user
report_port
…

Make sense? Is that feasible?

Cheers,

WB
