A module to submit a log processing job.
|
||||
|
||||
This role is a container for an Ansible module which processes a log
|
||||
directory and submits jobs to a log processing gearman queue. The
|
||||
role itself performs no actions, and is intended only to be used by
|
||||
other roles as a dependency to supply the module.
