I'll check the code - the metric item number is supposed to correspond
to the field number (counting from 0) in /proc/PID/stat. Maybe that has
come to grief or something or there is an error or overflow in the
conversion from jiffies to milliseconds.


hz was not initialized, so we are multiplying by -1. This is a bug
introduced when we split the proc PMDA off from the linux PMDA. Here's
the patch to fix it (same fix also applies for proc.psinfo.utime
and friends).

Cheers
