How to search for 'not' contais text

[Wayne Brantley]

The main log entry in Seq shows something like "Exception wrapped with SafeException" and "Exception allowed with NonSafeException".

Now, I created a view that is exceptions only:  Has(@Exception).

I want to now filter that view, I can type 'SafeException' in the filter and it shows me all Exceptions that have that in the text.

All good....

How do I filter and show all exceptions, EXCEPT the ones that have 'SafeException' in the text?

I tried using properties to do this, a not-contains, etc - but that text seems to be locked away inside this:

  "MessageTemplateTokens": [

    {

      "Text": "Exception wrapped with SafeException"

    }

  ],

Any help?

Hi Wayne-

You can do this with:

!"SafeException"

("SafeException" is an expression that matches text, while ! is the general NOT operator you can apply anywhere.)
