def server_classes::LogFileParser::_fetch_first_lines (    self,
  file_name
) 
  

This function returns the first 15 lines from current logfile without saving them anywhere.

def server_classes::LogFileParser::_test_keywords (    self,

  amount_of_keywords,
  teststring
) 
  

This is a recursive function, which tests if a list of keywords is part of a string (AND relation). If all keywords found 0 is returned, otherwise -1

keywordlist = list of all keywords
amount_of_keywords = number of keywords in list
teststring = string, which needs to be investigated

return -1 if line is not interesting
return 0 if line is taken

def server_classes::LogFileParser::analyse_log_file (    self,
  parser_file_name,
  file_time = None
) 
  

takes the templog file and goes through each lines and searches for keywords, if keywords are found, the line and the two lines before and after are dumped into a xml file, which the client can collect. This function uses the system function write to create the xml file. The dom function were to ineffectiv and sax unflexible.

parser_file_name = file name of the file, which needs to be parsed

def server_classes::LogFileParser::end_entry (    self,
  name
) 
  

This function inserts an end tag into the XML file. (name = tag name)

fd = file descriptor of the file
msg_tag = message tag to search for
