Performance Co-Pilot is a highly adaptable and established toolkit for those interested in examining the details of system performance. Designed from the ground up to compliment existing system monitoring, PCP is gentle in its approach as your statistics gathering mechanism. Likewise, PCP developers understand; what's most important for the sysadmin/end-user to monitor, may not be known, or even available to the upstream community. Hence, the following mantra is central to the PCP architecture: 'If it is important for monitoring system performance, and you can measure it, you can easily integrate it into the PCP framework'. This presentation will go over the basics of the toolkit, recent developments, how the developments fit within PCP's overall architecture, as well as some examples.
