If you look at the nagios documentation, the plugin output is explained
as (roughly) this (optional parts in brackets ( [] ):

v1/v2 format:

plugin output [ | perfdata ]

v3 format:

plugin output [ | perfdata ]
extended output
...
extended output [ | perfdata ]

Nagios v3 adds the extended output (which was originally limited to one
line). In the extended output, the first encountered | is the start of
the perfdata string and everything else that follows is perfdata. If you
print a perfdata on each line everything past the 2nd line is taken as
perfdata.

You could just print all perfdata after all output lines have been printed.
