# Overall Server Statistics

The server always collects certain overall server statistics. This includes the rate of inbound and outbound messages (expressed as number of messages per second), message memory usage, disk storage usage, and the number of destinations, connections, and durable subscriptions. Gathering this information consumes virtually no system resources, therefore these statistics are always available. You can view overall server statistics by executing the `show server` command.

The default interval for collecting overall server statistics is 1 second. You may wish to view average system usage statistics over a larger interval. The `server_rate_interval` configuration parameter controls the collection interval for server statistics. The parameter can be set in the configuration file or dynamically using the `set server` command. This parameter can only be set to positive integers greater than zero.
