Ari Rabkin commented on CHUKWA-185:
-----------------------------------
I have some code, but a couple concerns.
What should we do if a user tries to tail "/"? Creating millions of adaptors
is *probably* the Wrong Thing. But I'm okay saying "this is the user's
problem". Another approach is to only gradually create the FileTailingAdaptors
that do the real tailing, so that the user can kill it if it goes out of
control.
When the DirTailer is stopped, should that stop tailing all the files in the
directory, or just stop scanning for new ones?
Is DirTailer responsible for shutting off the FileTailers after a set period,
or is that the responsibility of the Tailers themselves?
> ability to tail a whole directory

> Issue Type: Bug
> Components: data collection
> Affects Versions: 0.1.2

> Assignee: Ari Rabkin

> Right now, FileTailingAdaptors watch particular files. It'd be great to be
> able to watch a whole path: to say something like /var/logs/*, where new logs
> created in that directory get picked up.
