How to exclude null in Splunk?

To exclude null values in Splunk, you can use the isnull function in your search.

Here's an example of how to use it:

1

index=yourindex | where isnull(field) = 0

This will return only the results where the field is not null.

You can also use the isnotnull function to achieve the same result:

1

index=yourindex | where isnotnull(field)

This will also return only the results where the field is not null.

If you want to exclude null values from multiple fields, you can use the AND operator to combine multiple isnull or isnotnull statements:

1

index=yourindex | where isnull(field1) = 0 AND isnull(field2) = 0

This will return only the results where both field1 and field2 are not null.

To exclude null values in Splunk, you can use the mvfilter function to filter out events that contain null values. Here's an example of how to use it:

index=yourindex | mvfilter(NOT isnull(field)) This will return only the results where the field is not null.

You can also use the coalesce function to replace null values with a specific default value, and then exclude those events. Here's an example:

index=yourindex | eval field=coalesce(field, "defaultValue") | search NOT field="defaultValue" This will replace all null values in the field with "defaultValue" and then exclude any events where the field is equal to "defaultValue".

Finally, you can use the where command to exclude events with null values. Here's an example:

index=yourindex | where NOT isnull(field) This will return only the results where the field is not null.

These are some of the ways you can exclude null values in Splunk. Choose the method that suits your needs and apply it to your search query.
