systems administrator is advised to check the Runaways graph under the Dashboard tab to locate, evaluate,<br />
<strong>and</strong> terminate these processes.<br />
A horizontal spread in the animated graph shows that additional users are logging into the server. If the graph<br />
shows an extreme tilt toward the horizontal, it simply shows that users are selecting that particular server to log<br />
into in order to do their work. In a Sun Ray environment, servers should be balanced so that no single server<br />
receives the bulk of users. If this is the case, then the Sun Ray server software needs to be adjusted to balance<br />
users more equitably among the pool of servers available. Switching users from one server to another manually<br />
may be worth considering if one server is receiving the bulk of logins.<br />
The CPU Load (animated) report is a predictive report. Systems Administrators can use this report to predict<br />
at which point, given an average workload, a server will “max out,” or reach 100% utilization. This is useful <strong>for</strong><br />
proactive analysis <strong>and</strong> capacity planning. This report can help Systems Administrators <strong>and</strong> IT managers<br />
determine approximately when additional servers will be required in order to spread load evenly among a pool<br />
of servers or to set thresholds at which additional user logins become inadvisable.<br />
