About Google Cloud Statistics
You can view statistics that are derived by processing Google Cloud flow logs. In addition, you can view statistics that are collected from the Cisco Catalyst 8000V routers.
Beginning with Cisco Cloud Network Controller Release 25.1(1), you can also apply filters to the statistics that are derived from the Google Cloud flow logs.
Router Statistics
Cisco Cloud Network Controller allows you to view router statistics for individual cloud context profiles within a tenant. Statistics are displayed for Cisco Catalyst 8000V routers within the cloud context profile.
Each router instance captures and stores the ingress and egress byte and packet statistics for each physical and tunnel interface. The Cisco Cloud Network Controller queries the routers for these statistics and maps the response to router statistics on the Cisco Cloud Network Controller. The statistics query repeats every 5 minutes for as long as the tunnel is up and operational. The Cisco Cloud Network Controller GUI displays the collected statistics for the routers.
Flow Log Statistics
Cisco Cloud Network Controller allows you to enable flow log statistics for individual cloud context profiles within a tenant. When statistics are enabled for a cloud context profile, statistics are collected for every IP address within the corresponding VPCs. Available statistics include ingress and egress bytes and packets, internal and external, for VPCs, regions, and endpoints.
The collected statistics are aggregated through the following hierarchy:
-
IP statistics are aggregated to determine endpoint statistics.
-
Endpoint statistics are aggregated to determine zone statistics.
-
Zone statistics are aggregated to determine subnet statistics.
-
Subnet statistics are aggregated to determine region statistics.
-
Region statistics are aggregated to determine VPC statistics.
The Cisco Cloud Network Controller GUI displays the collected statistics for VPCs, regions, and endpoints.
