How do I match multiple regex expressions?

BenzionYunger — Tue, 25 Dec 2018 13:29:07 GMT

I need to run a query that matches multiple expressions from JSON data. This is what I tried, but it didn't work:

regex (Primary.stackTrace="java.lang.RuntimeException: Sign in error message." | Primary.stackTrace="java.lang.RuntimeException: Login page failed to load within 45 seconds")

To properly diagnose regex problems, we really need to see some sample events.

Here is an event example to demonstrate. Notice Primary.stackTrace and Secondary1.stackTrace have different values. Only events with testStatus="Failed" can have a stackTrace, and some stackTraces are not one of the regex expressions.

Re: How do I match multiple regex expressions?

richgalloway — Tue, 25 Dec 2018 21:10:15 GMT

Your regex command contains regular expressions that don't match your events. "java.lang.RuntimeException: Sign in error message." expects the word "java" followed by any single character followed by "lang", a character, and the rest of the message. Try escaping periods: regex (Primary.stackTrace="java\.lang\.RuntimeException: Sign in error message" | Primary.stackTrace="java\.lang\.RuntimeException: Login page failed to load within 45 seconds").

Better yet, since these strings don't need to be expressions, let Splunk search for them as-is in your base search. Your performance may improve. index=foo ("java.lang.RuntimeException: Sign in error message." OR "java.lang.RuntimeException: Login page failed to load within 45 seconds") | ....

The first suggestion did not work either, it returned an error display msg "command not known primary", and the regex command for a single expression does work.
However, the 2nd suggestion did work effectively.
Thank You
