A2.2: I don't want to install any software on clients I wish to monitor.<br />
There are ways to configure the software so that there is no need to install software on client systems.<br />
This approach has some per<strong>for</strong>mance <strong>and</strong> security concerns but will function adequately in scenarios<br />
where one is monitoring a small number of systems. Instructions on how to do this are detailed in the<br />
<strong>Project</strong> <strong>Canary</strong> Installation <strong>and</strong> Configuration <strong>Guide</strong>.<br />
A2.3: I killed all the runaway programs but the CPU load indicator is still red. Why?<br />
It takes a while <strong>for</strong> <strong>Project</strong> <strong>Canary</strong> software to cycle through its update/processing cycle. One should<br />
see the indicator change within five to ten minutes if the change fixed the problem. The graphs take<br />
somewhat longer to update <strong>and</strong> may require up to 30 minutes to be redrawn with new data.<br />
A2.4: Is this just a tool <strong>for</strong> monitoring Sun Ray servers?<br />
<strong>Project</strong> <strong>Canary</strong> was designed <strong>and</strong> “tuned” to monitor Sun Ray servers in particular, however, it can be<br />
used to monitor the per<strong>for</strong>mance of any Solaris or Linux machine. With some modification, <strong>Project</strong><br />
<strong>Canary</strong> could be extended to run on HP-UX <strong>and</strong> AIX as well as any other Unix variant.<br />
A2.5: What is the significance of the number of users logged into multiple Sun Ray servers?<br />
Due to some software issues currently being addressed, one could log out of a Sun Ray session but not<br />
have all of one's processes terminated upon logout. These left-over processes wind up consuming CPU<br />
cycles <strong>and</strong> producing additional load on the Sun Ray server. <strong>User</strong>s are generally unaware that this<br />
happens. The multiple Sun Ray user report helps a systems administrator as well as a user to see how<br />
many different Sun Ray servers he/she is logged into.<br />
A2.6: Why show anything dealing with the automounter?<br />
If the -nobrowse option is not set in /etc/init.d/autofs a server could inadvertently be<br />
mounting many directories that are not needed. Compare the graphs <strong>for</strong> a system during the week <strong>and</strong><br />
then over the weekend. If the CPU load <strong>and</strong> number of users doesn't drop to around zero, then there<br />
are other issues to investigate. Look <strong>for</strong> abnormal network traffic on either the individual network<br />
cards or on the TCP Statistics Graph.<br />
