Hello,

We are seeing multiple iterations of the following error type in the Filebeat Module for Fortinet v 7.8.

When  
sentbyte=1569241255 + sentpkt=2797855  
and  
rcvdpkt=2166884 + rcvddelta=6625355

are greater than long allows:

`Value [15692412551409076086] is out of range for a long.`

`Network >> bytes` is mapped to long in the default Filebeat index template.

This seems to be a bug where both numbers are concatenated as strings. You can follow the issue here: [https://github.com/elastic/beats/issues/18707](https://github.com/elastic/beats/issues/18707)

Just need to finalize something then I will take a look at it and let you know how it goes.
