cockpit-pcp consumes pcp (performance co-pilot) metrics for the metrics page, so installing the package installs pcp on your distribution and auto starts it pmlogger (part of pcp, not Cockpit).

The large amount of ports being opened seems to be a known issue in PCP performancecopilot/pcp#1448

Is this a security issue? Not really, if you have your firewall properly configured no one should be able to snoop on your metrics.
