Perhaps one thought...
You can grep -v the file to exclude data. For instance --
cat mylogfile | grep -v "routine"
or
cat mylogfile | grep -v "routine" >mylogfile.2
The first example will send the file to stdout (your screen normally) while the second example will direct the output to a new file. In both cases, any lines with the word "routine" would be excluded.
You could try the second approach, and then if you find another keyword to exclude re-do the command but with the next keyword, for example
cat mylogfile.2 | grep -v "ordinary" >mylogfile.3
Be aware of overall filespace, and remember to clean-up when done. Sometimes log files are very large. Perhaps this gives you a start?
