You can plot five values for a server:
• Active Connections shows the number of active connections on the server. Equalizer
“smooths” the connection count using a sliding-window smoothing algorithm before being
plotted. If you have enabled the sticky timer, note that the number of active connections on a
server will be higher.
• Service Time indicates the time it takes a server to start sending reply packets once it has
received a client request. This value is very small for servers that are primarily serving static
HTML pages—typically 100-200 milliseconds. If the server is serving many active pages and
cgi-bins, this value will be much higher. The service time increases when the server is under
heavy load because client requests are queued until the server can handle them.
