Java code

now=$ (date + "%y-%m-%d")  
logfile= "slow_query. $NOW. Log"
$ (touch/var/log/tomcat6/$LOGFILE)  
# # msec is A maximum value for SOLR. Let's filter everything above that  
$ (cat/var/log/tomcat6/catalina.out | grep ' qtime ' | awk-f ' qtime= ' int ($NF) > = The ' >/var/log/tomcat6/$LOGFILE)

This Linux script can detect records larger than 800MS.
