Regular Expressions

Regular expressions are a powerful tool for matching patterns. They are used in Monitoring Studio X to define the strings to be search for, like a process name, an error in a file, some information in a Web page, some content in a database, etc.

Monitoring Studio X supports the following regular expressions:

Character Description Examples
. (dot) Represents any single character. Err.. will match Err01, Err02, ErrAB, etc.
[xyz] Matches any character enclosed in the square brackets. Err[123] will match Err1, Err2 or Err3
[Ee]rror will match either error or Error
[^xyz] Matches any character not listed in the square brackets. Err[^12345] will match any string containing neither 1, 2, 3, 4, and 5 such as Err0, Err6, Err7, but not Err1.
[a-z] Matches any character collated between the two characters specified. Err[0-9] will match Err0, Err1, Err2, Err3, Err4, Err5, Err6, Err7, Err8, and Err9
Err[A-Z][0-9] will match ErrA0, ErrA1, ErrS9, ErrZ0, etc. but not Err1A
Err[A-Z0-9] will match ErrA0, ErrA1, etc. and Err1A
[^a-z] Matches any character not collated between the two characters specified. Application[^0-9] will match ApplicationA,ApplicationB, Application! but not Application1
* Matches a string of zero or more strings of the regular expression specified. Err[0-9A-F]* will match Err, Err0, ErrA, Err11, ErrBF0001, etc.
Error.*ApplicationABC will match all lines that contain Error and ApplicationABC further (Critical Error 0x000295F0 on ApplicationABC)
+ Matches a string of one or more strings of the regular expression specified. Err[0-9A-F]+ will match Err0, ErrA, Err11, ErrBF0001, etc. but not Err
^ Matches the beginning of the line. ^Err will match all lines that begin with Err
$ Matches the end of the line. [0-9]+ connections$ will match all lines ending with xxx connections where xxx is an integer
\< Matches the beginning of a word. \<set will match any line containing a string that begins with set but not with a line that only contains the word unset
\> Matches the end of a word. [Aa]pplication will match all lines that contain the word Application or application but not ApplicationAA
\(expression\) Defines an expression which has to be processed as a unit regarding the modifier \*, + and \. \(\_[a-zA-Z0-9]\)+ will match only sequences like \_patrol, \_patrol_agent, \_patrol_console, etc.
exprA\|exprB Matches either exprA or exprB. \(firewall\)\|\(antivirus\) will match all lines that contain either the word firewall or the word antivirus
\ Escape character to indicate that the character that follows should be treated differently. \. will match the single character dot (.).
