How can I search for events that do not contain a field?

[chris]

Hi

I have defined a field for different types of events, the field is recognized in all the events I want to see it. Most likely because the regex is not good enough yet. So I am interested in seeing all the events that do not contain the field I defined.

How do I search for events that do not contain a specific field?

Thanks

Chris

| search foo="*"

If I want to find all events with a field named foo

* | where isnotnull(foo)

If I want to find all events without a field named foo

* | where isnull(foo)
