awk '{ for(i=1;i<=NF;++i) if (match($i,"Exception")!=0) {arr[gensub(/.*\.([a-zA-Z]*Exception[a-zA-Z]*).*/,"\\1","", $i)]++;} } END { for(v in arr) {print v, arr[v];} }' log

This is how it works:

>awk '{ for(i=1;i<=NF;++i) if (match($i,"Exception")!=0) {arr[gensub(/.*\.([a-zA-Z]*Exception[a-zA-Z]*).*/,"\\1","", $i)]++;} } END { for(v in arr) {print v, arr[v];} }' log
ServletException 2
JasperException 2
ConcurrentModificationException 1
DefaultWebException 1
NumberFormatException 2
StripesJspException 2
IllegalStateException 1
SolrServerException 1
IllegalBlockSizeException 1

If that piece of the log file you posted were put into a file called log, then try this:

egrep -o '\<\w+Exception\>' log | sort | uniq -c

Which would give you:

  1 ConcurrentModificationException
  1 DefaultWebException
  1 IllegalBlockSizeException
  1 IllegalStateException
  2 JasperException
  2 NumberFormatException
  2 ServletException
  1 SolrServerException
  2 StripesJspException

Or You simply can use

grep "<your search key word>" <log-file-name> redirect output to a file if you want.

There are several options also with grep command.
