RE: Monitoring JRun Memory Usage
Is there any way to get processor usage on the web server. I guess what I really want is a visual performance monitor for more than one server at a time (kind of like MS SQL server monitor) to keep track of our production web servers. The problem is we run Red hat Enterprise 3. Our techs won't install any gui like xwindows, and I can't find any program that can simultaneously monitor cpu load on several Linux servers in some sort of constantly updating graph. For our SQL servers, we actually have a projector down in the programming area which constantly projects the SQL server monitor on the wall. Kind of cool-- just wish we could get that for the web servers.

Re: Monitoring JRun Memory Usage
Rick,
We measure memory on our Windows 2000 server in two ways:
1) logging jrun metrics each minute though jrun.xml:
Set metricsEnabled to "true" in jrun.xml and use the following
metricsFormat to get a wealth of interesting statistics including
total and free memory (works for CF7):
Threads (total/busy/listen/idle):
{totalTh}/{busyTh}/{listenTh}/{idleTh}; Sessions (active/inMem):
{sessions}/{sessionsInMem}; Memory (total/free):
{totalMemory}/{freeMemory}; Requests (handled/delay/dropped):
{handledRq}/{delayRq}/{droppedRq}; Service (handledMS/delayMS):
{handledMs}/{delayMs}; Bytes (in/out):
{bytesIn}/{bytesOut}
We then use a Windows scheduled task to run a small java parsing app
that parses the coldfusion-event.log for high threshholds of memory,
threads, or sessions. If threshholds are exceeded, we get an email
with the details.
2) Windows performance montoring for CF-agnostic monitoring each minute:
We use the Windows performance monitor to record JRUN, IIS, and server
processor and memory usage to a CSV file each minute. This is useful
for investigating a poorly running machine or retracing why the server
crashed.
