CAPC ver 3.7.5.722
When I look at Cisco ASA device pages the Firewall Context tab is missing.
Release : 3.7
Component : IM Reporting / Admin / Configuration
The ASA device does not have any statistics monitored by any Metric Families on the Firewall context tab
If you need metrics from other Metric Families such as Firewall Connection Statistics to appear on the Firewall Context tab you can add views that support those metrics.The tab/view would then appear for those devices that support and have data for those metrics and are of the correct context.
