Vunetrix Manual: Regular Expressions

For some sensors, you can use regular expressions to match a search pattern. Vunetrix will use PCRE-RegExp. In the following, we will provide examples for the most common patterns.

Common Search Patterns

Find matches containing the word error or alarm:

\b(error|alarm)\b

 

Find matches containing the words error and alarm in any order:

(?=.*\berror\b)(?=.*\balarm\b).*

 

Find matches containing all of the words tree, flower, leaf, and bug, in any order:

(?=.*\btree\b)(?=.*\bflower\b)(?=.*\bleaf\b)(?=.*\bbug\b).*

 

Example

The search pattern

(?=.*\berror\b)(?=.*\balarm\b).*

will match the following expressions:

  • alarm error
  • error alarm
  • I am an error and I evoke an alarm
  • I am an alarm and I indicate an error
  • An alarm combined with an error indeed!
  • An error combined with an alarm, too!
