Claim 0:
1. A method for providing data associated with a radio frequency plasma processing system comprising an RF generator, a plasma chamber, and matching network coupled between the RF generator and the plasma chamber, the method comprising:
performing a plasma process on a plurality of substrates within the plasma chamber;
receiving measurements of an electric parameter from a sensor coupled to the plasma processing system during the plasma process performed on each substrate;
computing an aggregated statistic based on the electrical parameter for the plurality of substrates;
determining a desired range for the electrical parameter based on the aggregated statistic;
performing the plasma process on a selected substrate and receiving measurements of the electric parameter for the selected substrate;
while performing the plasma process on the selected substrate;
determining that the electric parameter for the selected substrate deviates from the desired range for the electrical parameter; and
determining an expected life of a capacitor in the matching network based on the deviation of the electric parameter for the selected substrate from the desired range; and

issuing an alert indicating:
the electric parameter for the selected substrate deviates from the desired range for the electrical parameter; and
the expected life of the capacitor.
