The average service time of all of the servers in the cluster. The
service time is the time it takes a server to start sending reply
packets once it receives a client request. The average service time
is a reasonable indication of the overall performance of the cluster.
Initialized to 0 when the system boots. By design, when a server
with a non-zero service time transitions to having no active
connections for some period of time, Equalizer stops adjusting the
service time and continues using the last service time value in load
balancing decisions. This is why sometimes the service time is not
equal to 0 when there are no active connections to the server.
The total number of active connections on the servers in the cluster.
The number of connections served by the cluster each second. This
is a good indication of how many "hits" the site is getting.
The average of the server agent return values for all servers in the
cluster. If you have not configured server agents, -2 is displayed.
The amount of time between updates of the plot data.
The time interval displayed in the plot. Sets the horizontal time
scale for the plot. For example, if 5 mins is selected, all the data
collected over the last 5 minutes is displayed in the plot.
