Throttling Net Connections

Specifies the maximum number of network connections that Content Gateway accepts. The default value is 45,000. Setting a Content Gateway throttle limit helps to prevent system overload when traffic bottlenecks develop. When network connections reach this limit, Content Gateway queues new connections until existing connections close. Do not set this variable below the minimum value of 100.

Maximum Connections

Specifies the maximum number of client connections allowed before the ARM starts forwarding incoming requests directly to the origin server. The default value is 1 million connections. If you change this option, you must restart Content Gateway.

Concurrent Connection Limit: Maximum concurrent connections	Specifies the maximum number of concurrent HTTP/HTTPS connections a client is allowed. The default is 1000. The supported range is: 1 - 45000
Concurrent Connection Limit: Alert when limit exceeded	When enabled, causes Content Gateway to generate an alert when a client exceeds the maximum concurrent connection limit. In addition to displaying the alert in the Content Gateway manager, it is also logged in /var/log/messages and content_gateway.out.
Concurrent Connection Limit: Close excessive connections when limit exceeded	When enabled, causes Content Gateway to close excessive connections when the limit is exceeded.
Connection Rate Limit: Maximum connection rate	Specifies the maximum connections per second, averaged over a minute, that a client can make. The default is 100. The supported range is: 1 - 1000
Connection Rate Limit: Alert when limit exceeded	When enabled, causes Content Gateway to generate an alert when a client exceeds the maximum connection rate limit. In addition to displaying the alert in the Content Gateway manager, it is also logged in /var/log/messages and content_gateway.out.
Connection Rate Limit: Close excessive connections when limit exceeded	When enabled, causes Content Gateway to close excessive connections when the limit is exceeded.
Exceptions	Specifies IP addresses and/or IP address ranges to which connection limits are not applied. IP addresses can be IPv4 or IPv6 (IPv6 support must be enabled). Multiple addresses or ranges can be specified in a comma-separated list.

Low Memory Mode: Enabled/Disabled	Select Enabled to suspend content analysis when there is a low memory condition.
Low Memory Mode Duration	Specifies the length of time, in minutes, that content analysis is suspended. If the low memory condition resolves itself before the timer expires, analysis resumes and the low memory mode trigger resets. If the timer expires, analysis resumes and the low memory mode trigger is not reset.
