- Has a fully distributed architecture; any client may interact with any instrumented server or application.
- Has a plug-in architecture for instrumenting any custom application or server.
- Can query hundreds of operational measurements from operating systems, Apache, Sendmail, MySQL, the Java JVM, VMWare, KVM, etc.
- Can send operational parameters to remote processes, to change their behavior (cf. Computational Steering)
- Can query or send any type of value, including: integers, strings, floating point numbers, and arbitrary composite data structures.

[edit] Origin
Performance Co-Pilot was originally created by SGI as a proprietary product, exclusively for SGI customers. In 2000, the core of PCP was re-released as free software, under the GNU LGPL. Additional proprietary components have been re-released as free software since then. Currently, circa 2009, an active community of contributors is enhancing the open source distribution of PCP and releasing new tools built upon it.
PCP's initial design was done at SGI in Melbourne by Ken McDonell and Mark Goodwin, starting in October 1993. The pair were joined by Seppo Keronen and Jonathan Knispel, early in 1994. These four produced the initial version of Performance Co-Pilot 1.0, which was released in April 1995 as add-on software for SGI's IRIX operating system. Components included in that initial release were: pmcd (Ken and Jonathan), pmchart (Mark), libpcp (Ken), pmie (Seppo), pmgadgets (Jonathan), and a host of other smaller bits and pieces. Other significant early contributors were Ania Bodeit, David Chatterton (pmview), Ivan Rayner, Nathan Scott and Tim Shimmin.
