How the values are calculated

The Load value, %L, is derived from the LINUX system load average. To make the value comparable across machines with varying numbers of cores, the number is divided by the number of cores on the system.

The calculation is:

// load avg values are 0.00 precision double avgs[3];
// get load averages for 1, 5, and 15 minutes getloadavg(avgs, 3);
// 5 minute_load_average * 10000 / number_of_cores Load = avgs[1] * 10000 / get_nprocs();

The Connection value, %C, is the sum of proxy.process.http.current_server_connections and proxy.process.http.current_client_connections.

The Bandwidth value, %B, is the value of proxy.node.client_throughput_out.
