Its a single log file which is getting updated 24*7 . Its about 120 MB.
Every second entries are getting appended to the log file .
Log entry looks like

Code:

The alert needs to be sent when "Child process terminated gracefully " is encountered. How can we scan the newly appened lines in log file for the error message instead of full scan so that past errors can be ignored.
