Grokconstructor.appspot.com Website Review

files from various sources, parse them into a JSON format and put them into one or more databases, index engines and so forth - often the integrated elastic search engine with a simple web frontend to search them. In my experience the hardest part is to get the regular expressions and provides Grok Discovery that sometimes can suggest regular expressions. This site, GrokConstructor, goes beyond that by providing an incremental construction process that helps you to construct a regular expression that matches all of a set of given log lines, and provides you a matcher where you can simultaneously try out your regular expression on several log lines. You can find the source go to the applications. There is a short explanation at the top, and you can call up a random example to try things out. If you want to that simultaneously matches all of a given set of log lines. As input you provide those lines to match and select the libraries of grok patterns you want to choose from, and possibly give additional prefix of the yet unmatched rests of the log lines, or select one of the patterns from the grok library that matches a start segment of all rests of the log lines, or input a pattern that matches the next segment. In each case the next segment is usually the next logical they are matched, and displays the named groups that result from matching the line. If the expression matches only a start segment of the line the unmatched rest is displayed. If a line is not matched at all we show the longest prefix of the expression that matches the line. As input you provide those lines to match and select the libraries of grok patterns you want to choose from, and possibly give additional will want to check and refine the pattern with the Matcher. Warning: this is alpha state, so don't expect it to work or anything. :-) Please report problems and, if possible, make good suggestions how to translate troublesome placeholders to a appropriate grok expressions. It would be comparatively easy to extend this to other logging libraries like logback etc. if someone comes up with good suggestions
