RE: Tomcat Status Metrics: RRDTool Graph: Analysis
Thanks, Chris. I'll do some load testing. I was thinking of using siege or apache bench. _Tomcat: The Definitive Guide_ is my guide. Do you know of a better way of getting heap numbers out of Java? Right now I've got three metrics: jvm_mem_free; jvm_mem_max; jvm_mem_total. Examining the graphs, I see that 'free' and 'total' are not exact opposites.

Tomcat Status Metrics: RRDTool Graph: Analysis
Hi all, I was recently asked to create a way to analyze Tomcat performance. I decided to grab stats from the /manager/status?XML=true page and push those metrics into rrdtool. There are all sorts of other details to the analysis which I will leave out. In any case, I was wondering if someone could have a look at the attached graph and tell me if I can conclude that the performance directives in server.xml do not need to be modified.

Tomcat status 75 error
Hi, I have a series of relatively high transaction volume tomcat servers which are sporadically hitting thread issues. We run with with tomcat 4.1.27 at the current time. The behaviour we notice is after several days of around one hundred thousand transactions our tomcat instances hang with the catalina.out message of: SEVERE: All threads are busy, waiting. Please increase maxThreads or check the servlet status75 75 Stopping service Tomcat-Standalone I've done a quite a lot of reading on this and in some cases there is an indication that moving to a later tomcat version alleviates the issue. However in many others it indicates that this problem is due solely to the code whereby the threads are not exiting cleanly. We have a classic 3-tier architecture and we can see the db connections closing. I have tired reproducing this error on a tomcat 5 environment and I get a similar but not identical error: org.apache.tomcat.util.threads.ThreadPool logFull SEVERE: All threads (15) are currently busy, waiting. Increase maxThreads (15) or check the servlet status The tomcat install continues to function correctly after this has occurred. What I would like to know is do the 2 error messages correspond to the same underlying issue. I strongly suspect it is an application code issue so I would like to be able to count Tomcat out of the loop.

From: dl [mailto:[EMAIL PROTECTED] Subject: Tomcat Status, Administration and Manager not working conf\Catalina\localhost\admin.xml and server\webapps\admin\admin.xml The latter .xml file isn't actually used; only the one in conf/Catalina/localhost is significant. .. valves were uncommented to allow access to localhost. I presume you mean allow access only to localhost or restrict access to only localhost. Access is normally permitted to all IP addresses. Valve className=org.apache.catalina.valves.RemoteAddrValve allow=localhost/ Use the actual IP address (usually 127.0.0.1), not the pseudo-DNS name.

From: dl [mailto:[EMAIL PROTECTED] Subject: RE: Tomcat Status, Administration and Manager not working .. but unfortunately the other two links still do not work .. same error reports Both the Status and Tomcat Manager links refer to servlets within the manager app, and both paths, by default, only require a role of manager to access them. Have you made any changes to the conf/Catalina/localhost/manager.xml or server/webapps/manager/WEB-INF/web.xml files? The former contains the file system location of the manager app, the latter the servlet mappings and security constraints. - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.

replace tomcat Status report
I finally gave up in searching for this(and my partner is soon to give up to) so I decided to ask here. When I go to http://localhost:8080/NoPage.jsf, tomcat tells me the tomcat version and everything so I can google for tomcat hacks on that version. I would much prefer to hide the version number with my own Resource not found page. Is this possible? for exceptions my app runs into, I am just using a filter to redirect to a page that doesn't show a tomcat version too. thanks for any info, dean - To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Re: replace tomcat Status report
Hi there I belive you should be able to edit you web.xml with info to overwrite the default error pages. Never done it myself but it´s a hint. =) Good luck Den 6/14/2006, skrev Dean Hiller [EMAIL PROTECTED]: I guess I should add that my partner did add this stuff to our ROOT.war(we deleted the ROOT directory) but it doesn't seem to work... error-page exception-typejava.lang.Throwable/exception-type location/error.jspx/location /error-page error-page error-code500/error-code location/error.jspx/location /error-page error-page error-code404/error-code location/error.jspx/location /error-page thanks, dean Dean Hiller wrote: I finally gave up in searching for this(and my partner is soon to give up to) so I decided to ask here.
