Code:
tail -f imp.log | nawk '!/Bps/' | sed -e 's/\ \[\<strategy.SNTH\>\]//g' -e 's/\([0-9][0-9]\),[^ ]*/\1/g'

This is a slightly stronger match: -

Code:
tail -f imp.log | nawk '!/Bps/' | sed -e 's/\ \[\<strategy.SNTH\>\]//g' -e 's/\([0-9][0-9]:[0-9][0-9]:[0-9][0-9]\),[0-9][0-9]*/\1/g'

Your pattern for strategy.SNTH is a little overcomplicated: -

Code:
s/ \[strategy.SNTH\]//g

is sufficient
