The libpcp-pmda-dev package contains the performance co-pilot (pcp) library and header files needed to develop performance metric domain agents (pmdas). each pmda exports performance data for one domain; for example the operating system kernel, cisco routers, a database, an application, etc.

the performance co-pilot provides a unifying abstraction for all of the interesting performance data in a system, and allows client applications to easily retrieve and process any subset of that data.
