Logging is off by default. To enable logging, select the Generate Limiter Statistics check box in System Configuration > QoS/LimitingQoS > Limiter Options. When this is enabled, a log is generated every five seconds. The following information is recorded in the logs:

• curconns: The total number of active connections on the system (at this specific moment in time).

• totconns: The total number of attempted connections (of all time). If you reset the statistics this value is cleared.

• totreqs: The total number of successful requests (of all time).

• totrulereq: The total number of requests that have matched a rule (of all time).

• totcblocked: The total number of connections that have been blocked (of all time). This is client connections (no HTTP processing).

• totrblocked: The total number of HTTP requests that have been blocked (of all time), which were not blocked by the client connection blocking.

• totruleblock: The total number of URL rules that have been blocked (of all time), which were not blocked by the client connection blocking and not blocked by HTTP request blocking.

• totmaxcblocked: Total cumulative number of client requests blocked due to the maximum number of connections being exceeded.

When the bandwidth limit is exceeded, logs similar to the ones below are generated:
