With filters, you have the possibility to define some conditions. As a result, some events will be sent and some don't, according to your conditions.
Use the dropdown to select the property on which you want to filter, then select the operator and the value to filter on.
Available operators:
is
isn't
match regex (see also 'About regex' section)
doesn't match the regex (see also 'About regex' section)
contains
doesn't contain
starts with
doesn't start with
ends with
doesn't end with
exists
doesn't exist
is empty
An "Advanced" filter can be used when a simple one is not sufficient.

With Advanced filter, you can use formula and advanced functions, simply click on the button on the right of the field to see all available functions.
Supported operators:
= (equals to)
> (smaller than)
< (greater than)
!= (different from)
Supported conditions:
AND
OR
Supported functions:
Always use " " to enter a value in advanced mode. All values entered without " " will be treated as a number.
Both simple and advanced filter can manage regex:
