William,

Assuming a vanilla PCP install with pmlogger enabled (and possibly configured 
to ensure any locally important metrics beyond the defaults are being 
collected) and running on the system of interest (where pmcd is also running)) 
...

It is the -k option to pmlogger_daily that controls how long the PCP archives 
are kept, the default is 14 days.

pmlogger_daily is usually run by cron, so you'll need to add a -k <pick your 
number of days> to the pmlogger_daily line in /etc/cron.d/pcp-pmlogger

Note that my "assumptions" above need not apply, and in that case the change 
needs to be made on the system where pmlogger is being run.
