Here, a simple solution of log analyzer which allows error searching; This tools gives the possibility to search specific error keywords and skip others:
01 | String logFileNameAndPath = baseDir+File.separator+"server.log"; |
04 | ArrayList<String> errorsKeyword = new ArrayList<String>(); |
05 | errorsKeyword.add("ERROR ["); |
08 | ArrayList<String> errorsToSkip = new ArrayList<String>(); |
09 | errorsToSkip.add("ERROR [STDERR]"); |
11 | 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.
