Item Preprocessing with Regex
In this lecture, I add a pre-processing step to the item that instructs the agent to read the windows failed logon events.
The regular expressions demonstrated in this video are,
|(.*)||\0||Returns only the first line of the complete failed logon event text.|
|Account Name:\t\t(.*)||\1||Returns the 1st occurrence of the Account Name in the log text, that created the event.|
|Account Name:(.|\n)\tAccount Name:\t\t(.)||\2||Returns the 2nd occurrence of the Account name in the log that created the event.|
