Subject [jira] Commented: (CHUKWA-268) Create an interface to manage all Adaptors
Date Tue, 09 Jun 2009 02:54:07 GMT


Ari Rabkin commented on CHUKWA-268:

Agent.processCommand() has never handled anything other than "add".  All those other commands
are implemented in AgentControlSocketListener.  The renaming just reflects the status quo.

We can certainly add more things to the agent control interface. I'm open to advice on whether
adaptors should have access to the full generality of agent functionality, or only to a subset.
I initially opted for subset, but mostly because it's easier to add things to an interface
than to revoke them in the future.

> Currently the agent manage all adaptors and it's fine however it will be cleaner to have
an AdaptorManager interface. The agent will just implement this interface without changing
anything, but adaptors will retrieve the manager using ChukwaFactory. This will remove the
hard dependency between Agent and adaptors.
