To your last paragraph, you won't see any request itself "taking a lot of memory". You can't get any insight into the memory used within a given request. (Well, the CF Server Monitor tries to offer that, but many have learned that turning on "Memory Tracking" there can be its own death knell for a server.)
Instead, you may mean merely that you can see in the monitor graph what memory is used by CF overall, but again I'll plead with you to read the blog entry I pointed to ( http://www.carehart.org/blog/client/index.cfm/2010/11/3/when_memory_problems _arent_what_they_seem_part_1) which discusses how that is often a myth (concern over "high memory use"). More important, and to your very problem of feeling "blind" about what happened some time ago, I discuss there how what really matters is what errors appear in the [cf]\runtime\logs (or [jrun]\logs if on Multiserver, or [cf]\logs\cfserver.log if on *nix.) That log can tell you if you are in fact having a real memory problem, or if perhaps your problems may have some other explanation. Trust me: all I do is help people solve CF server problems, and there can be many, many different explanations, often ones that you'd never dream of. /charlie From: [email protected] [mailto:[email protected]] On Behalf Of Frank Moorman Sent: Tuesday, February 01, 2011 1:19 PM To: [email protected] Subject: Re: [ACFUG Discuss] CF9 Performance Thank you Charlie... And Ajas and Chris... We are on the same mental page. My whole reasoning for this thread is that I am having random timeouts. (I know they are not really random ;-> ) I do think they are related and I do not believe the page actually timing out is the real problem. When it fails, I know which page failed, but I do not have any tool to see what else was going on at the same time. I was looking to see what tools are available that will give me more server information, preferrably one that will tell me what was happening when the error occurred, not 10 minutes later when I can actually look at a monitor. I mentioned the CFDOCUMENT with the images, because I know it is a big performance hit. I suspect (but currently have no proof) that the pages that are failing are executing at the same time as the pdf creation process. (Yes, I am using localurl) I also suspect it is the other pages timing out instead of the actual pdf creation page, because I know I have increased the default timeout individually on those pages in the past. I do not want to increase the global timeout default, because while that may help give the other pages a few more seconds to finish what they are doing, it will not fix the root cause and only (temporarily) mask the problem. If/when (probably when) I install Fusion Reactor, I will try to see the common theme with the multiple timeouts. If I see createInspectionForm.cfm running at the same time in every case and taking a lot of memory, I will definitely raise an eyebrow in that direction. However, if I see a long running memory intensive sql at the same time, I will know where else to look. Right now, I believe blind is an appropriate term, and I am only guessing based on past experience. Once again, Thank you everyone...
