as a “Close Window” button which will cause the popup window to close.
These graphs display the CPU load as well as the run queue and the number of users on the server. Note that
the load (the red lines on the graph) rise during business hours when users are actively using the server and dip
down again at night. On weekends, the load will drop as well. On a Sun Ray server or any server with users
running applications, watch the CPU load on the local Project Canary installation carefully. If the red lines do
not fall when the server should be idle, that is a good fast indicator that there are either runaway processes on
the server or processes that are hard at work when the may not need to be. On multiuser servers or Sun Ray
servers where users are running productivity applications, browsers left open viewing webpages with
animated images, Java applets that cycle images or the page itself, or flash animation will cause the browser to
use cycles even when the user is not actively using the browser. On the Sun Ray server graph, note that CPU
load and number of users tend to rise and fall together. If the run queue drops and the CPU load does not, then
that is also another good indicator that runaway processes or processes that are using an inordinate number of
