hi Nagios Community

hope this email finds you all well..

just wanted to ask for advise from the community

Nagios Network Analyzer does it have two NIC or one NIC

such that

1 NIC - ingress Netflow

1 NIC - Apache Web App login

or 

1 NIC - for Ingress Netflow and Apache Web App Login and downloading of reports..

reason i am asking is because i am getting 100% CPU when running pdf reports and Gateway timeout on the Nagios Network Analzyer Web interface..

or is there any documentation to optimize the Application Reporting in Nagios Network Analyzer..

My CPU count is 16

RAM - 32gb

Disk -3T

Nic -10Gbps

Appreciate the Community insight and experience in assisting me 

Thanks
