摘要： Systems and methods for consolidating metrics and statistics used for load balancing by a plurality of cores of a multi-core intermediary are disclosed. A timer operating on each packet engine of each core in a multi-core system may expire. A consolidator may store, responsive to expiration of the timer, a set of counter values from each of the packet engines to a first storage location. The consolidator may send to each packet engine a message to update the set of counter values. The consolidator may, upon completion of updating the set of counter values by the packet engines, send a second message to the packet engines that includes a consolidated set of counter values determined based on the updated set of values from each packet engine. Each packet engine may establish settings and parameters for load balancing based on the consolidated set of counter values.

摘要： The present invention is directed towards systems and methods for aggregating and providing statistics from cores of a multi-core system intermediary between one or more clients and servers. The system may maintain in shared memory a global device number for each core of the multi-core system. The system may provide a thread for each core of the multi-core system to gather data from the corresponding core. A first thread may generate aggregated statistics from a corresponding core by parsing the gathered data from the corresponding core. The first thread may transfer the generated statistics to a statistics log according to a schedule. The system may adaptively reschedule the transfer by monitoring the operation of each computing thread. Responsive to a request from a client, an agent of the client may obtain statistics from the statistics log.
