Good day.  
Tell me, please, I collect netflow using filebeat.  
There are fields  
''''  
"egress\_interface" : 199,  
"ingress\_interface" : 277,  
''''  
Through SNMP, I found out which network interfaces correspond to these indexes.  
How can I overwrite these values ​​on the described ones?

Perhaps it can be done somehow through  
''''  
"observer.ingress.interface.name": [  
"eth0" ],  
''''  
If this is so, please tell me where exactly it is necessary to specify these parameters?  
Thank you
