Log File Monitor
The Log File Monitor watches text files and notifies you when specific text is seen. You can use standard Windows wildcard characters ? and * to specify more than one file.
The Log File Monitor employs an efficient mechanism to only read changed parts of the file(s). The search text can be specified as a simple phrase, or you can use the power of regular expressions for more complex text searches.
The first option is a simple text search. You enter exactly the text that you want found, and specify whether the case should match or not. This is good for searching for specific phrases or specific words or parts of words. An example would be: database connection error
The second option lets you specify the search text with Regular Expressions (a great refresher is available at RegExLib.com). For example, if you want to search for the word 'error' OR 'failure' you would enter: error | failure
