The following are some examples using both method definitions:ĭescription.extract(/(server(100|\d?))/)ĭescription.extract(/(server(100|\d?))/, 1)ĭescription.extract(/(server(100|\d?))/, 2)ĭescription.extract(/(server(100|\d?))/, 3)ĭescription.extract(/server(100|\d?)/, 0)ĭescription.extract(/server(100|\d?)/, 1)ĭescription.extract(/server(100|\d?)/, 2)ĭescription.Zip tool has gained its appeal and worldwide interests primarily because of its ability to compress files efficiently. If the given regular expression matches the string but does not contain at least index number of parenthesized sections, it returns the whole string. If the string does not match the given regular expression, it returns empty string. : Gives the string that matches the indexth parenthesized section (group) of the given regular expression. If the given regular expression matches the string but does not contain any parenthesized sections, it returns the whole string. : Gives part of the string that matches the first parenthesized section (group) of the given regular expression. Working with extract method may require understanding of Capturing Groups to get desired results. You can refer here for further information about string processing methods. You can use extract string processing method to extract desired matching group according to given regular expression to set into an alert field. Regular Expressions for Setting Alert Fields with 'Extract' String Processing Method To create an alert via your email integration if the subject contains Daily Report and the message contains one of Critical, Error or Down, the following regex can be used within Matches rule: The following are some examples for common use cases in which using Matches condition operator makes sense: You can refer Action Filters for further information about condition operators. This operator provides ability to define complex filtering in a single condition rule and reduces your dependency to already-defined condition operators. If type of the input value is List, then the condition will be matched if at least one of list items matches the given regular expression. The conditions with Matches operator are fulfilled if whole string value matches the pattern of given regular expression. Regular Expressions for Filtering with 'Matches' Rule Regular expressions can essentially be used for two purposes: Defining a filtering rule with Matches operator and extracting data to set for an alert field with extract string processing method. You can extract the desired information in a more powerful way by using regular expressions on many cases. Opsgenie provides opportunity of using Java-like regular expressions to strengthen filtering and extracting information to define alert fields that both can be used in integrations, alert policies and callbacks.
