The M and CCS columns from jstat output can present a dash("-")
for NaN values, such as :
----------System.out:(13/1261)----------
S0 S1 E O M CCS YGC YGCT FGC FGCT CGC CGCT GCT
0.00 0.00 0.00 0.00 - - 0 0.000 0 0.000 0 0.000 0.000
0.00 0.00 0.00 0.00 - - 0 0.000 0 0.000 0 0.000 0.000
0.00 0.00 0.00 0.00 - - 0 0.000 0 0.000 0 0.000 0.000
0.00 0.00 0.00 0.00 - - 0 0.000 0 0.000 0 0.000 0.000
0.00 0.00 0.00 0.00 - - 0 0.000 0 0.000 0 0.000 0.000
0.00 0.00 0.00 0.00 - - 0 0.000 0 0.000 0 0.000 0.000
0.00 0.00 0.00 0.00 - 28.19 1 0.571 0 0.000 0 0.000 0.571
0.00 100.00 0.00 14.85 31.29 28.19 1 0.571 0 0.000 0 0.000 0.571
0.00 100.00 0.00 14.85 31.29 28.19 1 0.571 0 0.000 0 0.000 0.571
0.00 100.00 0.00 14.85 31.29 28.19 1 0.571 0 0.000 0 0.000 0.571
This proposed fix updates the awk scripts which are checking output lines.
For the M and CCS columns, allow either a floating point value or a dash.
e.g. "([0-9]+\.[0-9]+|-)"
