Here, a simple solution of log analyzer which allows error searching; This tools gives the possibility to search specific error keywords and skip others:
String logFileNameAndPath = baseDir+File.separator+"server.log";
// Errors keywords
ArrayList<String> errorsKeyword = new ArrayList<String>();
errorsKeyword.add("ERROR [");
// Errors to skip
ArrayList<String> errorsToSkip = new ArrayList<String>();
errorsToSkip.add("ERROR [STDERR]");
LogAnalyzer.analyzeLog(logFileNameAndPath, errorsKeyword, errorsToSkip);
Following, examples of searching report:

Some figures of the above reports:
– 2 seconds for the analyze of file whose size is 47Mo
– 34 seconds for the analyze of file whose size is 110Mo
of course, these figures depend of number of errors sought/searched or errors to be skipped.
