Re: How can I display number of requests over the past n seconds?
Mmmm, I think people is answering more than one question ;-)
If you need to be strict with respect to the timings, that is, you need
exactly the number of requests in the past five seconds counting from
the moment your request is done, you will need the solution proposed by
Tim. Just remember to synchronize the access to the list, to prevent
ConcurrentModification exceptions while you iterate over the list to get
the counter values :-)
If the time buckets idea works well for you, both Yoav and Justin
proposals are good. I just prefer Yoav one because I guess the cost
associated to the hash function, even if it is simple, is greater than
the associated to a thread that is sleeping most of the time (I mean, in
processing time terms).
I think Yoav idea could be implemented like this (with a variation on my
own ;-):
public class Historic extends Thread {
private static final int NUM_COUNTERS = 6;
private static final int INTERVAL = 5000;
private int[] counters = new int[NUM_COUNTERS];
private int pos = 0;
public Historic() {
super();
this.setDaemon(true);
}
public void run() {
try {
while (true) {
sleep(INTERVAL);
synchronized (this) {
pos = (pos + 1) % NUM_COUNTERS;
counters[pos] = 0;
}
}
}catch (InterruptedException e) {
}
}
public synchronized void addRequest() {
counters[pos] += 1;
}
public int[] getCounters() {
int[] copy;
int posCopy;
synchronized (this) {
System.arraycopy(counters, 0, copy, 0, NUM_COUNTERS);
posCopy = pos;
}
int[] values = new int[NUM_COUNTERS];
int count = 0;
int index = posCopy;
for (int i = 0; i NUM_COUNTERS; i++) {
count += copy[index];
values[i] = count;
index = (index == 0 ? NUM_COUNTERS : index) - 1;
}
return values;
}
}
Just instantiate the class and start it in your Filter initialization,
and call addRequest() on each received request. The getCounters() gives
you the number of requests in each time slice. Ah, and remember to
interrupt it on Filter finalization :-)
There is no guaranty that the pos variable will be changed exactly
each five seconds, as the sleep() method is not accurate by design. In a
highly loaded server with only one CPU, the time slicing will become
worse. If you detect the thread scheduling is too much biased, you can
raise its priority.
If this is not enough, you will have to calculate the cursor position in
each request, implementing the hashtable proposed by Justin:
public class Historic {
private static final int NUM_COUNTERS = 6;
private static final int INTERVAL = 5000;
private int[] counters = new int[NUM_COUNTERS];
private int pos = 0;
private long ts = System.currentTimeMillis();
public Historic() {
}
public synchronized void addRequest() {
adjust();
counters[pos] += 1;
}
public int[] getCounters() {
int[] copy;
int posCopy;
synchronized (this) {
adjust();
System.arraycopy(counters, 0, copy, 0, NUM_COUNTERS);
posCopy = pos;
}
int[] values = new int[NUM_COUNTERS];
int count = 0;
int index = posCopy;
for (int i = 0; i NUM_COUNTERS; i++) {
count += copy[index];
values[i] = count;
index = (index == 0 ? NUM_COUNTERS : index) - 1;
}
return values;
}
private void adjust() {
long now = System.currentTimeMillis();
while (now - ts = INTERVAL) {
pos = (pos + 1) % NUM_COUNTERS;
counters[pos] = 0;
ts += INTERVAL;
}
}
}
HTH,
Rodrigo Ruiz
I need to display on a .jsp page the number of requests for Tomcat in the past 5 / 10 / 15/ 30 / 45 / 60 seconds. I've already implement a Filter will count the total number of requests. I did this with a static int, which is incremented everytime a request comes in. But what should I do so that I can show number of request over past time intervals? Since the present time is always changing, the past n seconds is constantly changing also.
Thanks in advance,
Tom

RE: Tomcat 4.1.30 ThreadPool.adjustLimits
Hi, That was an excellent message. Your approach is flawless. You can keep using your hack, which isn't that crude at all. You can keep using the 5.x Connector code by and large with 4.1.30 (though not earlier versions of Tomcat 4.1), it should be just fine. And I tend to agree than 10 as MAX_THREADS_MIN is too high: something like 2 or 3 seems reasonable to me. Please open a Bugzilla item asking for this to be modified, and I will address it. Thanks, Yoav Shapira Millennium Research Informatics -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Sent: Tuesday, August 03, 2004 5:30 PM To: [EMAIL PROTECTED] Subject: Tomcat 4.1.30 ThreadPool.adjustLimits I have several questions that apparently center around the org.apache.tomcat.util.threads.ThreadPool class contained in the tomcat-util.jar file included in the Tomcat V4.1.30 distribution. Background: Using V4.1.30 in a standalone, relatively minimal configuration with the Coyote HTTP/1.1 Connector. Deployed on several hundred (ultimately several thousand) UNIX servers of various flavors. Least common denominator server types supporting only JVM 1.2.2 limit us to 4.x Tomcat. Tomcat used solely for foreign system access to server data via specialized servlets in a confined/controlled environment (not internet exposed). Resource considerations require limiting Tomcat to a tiny fraction of it's concurrent connection capacity (primary function of servers is to host a vast load of multi-user business management applications). What I'm after is limiting to a max of 4 concurrent connections on the stock configuration. Initially though I could simply set maxProcessors=5 and minProcessors=1 (earlier experimentation suggested actual concurrent connections was one less than maxProcessors value). I unfortunately misinterpreted the warning message generated during startup, WARNING: maxThreads setting (5) too low, set to 10, to be a suggestion. I now understand this is a statement that Tomcat (ThreadPool.adjustLimits() method logic, in particular) actually reset the maxProcessors value to 10. Went looking for ThreadPool in V4.1.30 source (based on warning message origin tags) without success, then remembered something about TC V4.1.30 using TC V5.x Coyote connector. Then located what I believe to be the operative logic in jakarta-tomcat-connectors portion of Tomcat V5.0.19 source (version I happened to have handy). Sure enough, method adjustLimits() forces maxThreads value (apparently set by digester logic based on TC4.x.x maxProcessors) to MAX_THREADS_MIN (hardwired to 10 in source) if value supplied in server.xml is less than that. I knocked off a copy of org.apache.tomcat.util.threads.ThreadPool, changed MAX_THREADS_MIN to 2, compiled, and surgically deployed resulting classes under server/classes (effectively overriding the ThreadPool class in server/lib/tomcat-util.jar) on a test box. Appears to be behaving reasonably, now limiting concurrent connections to that specified in server.xml file. I know - crude hack - but I didn't have much recourse without fielding something to front-end Tomcat. My questions: (1) Is there some other reason for this essentially arbitrary (upward) adjustment of the maxProcessors/maxThreads value - beyond the rational provided in the source commentary ... fix provides reasonable settings for a single CPU with medium load.? (2) Is the ThreadPool source from Tomcat V5.0.19 the appropriate version to use as I have outlined above? (It appeared to be the closest date match to the Tomcat V4.1.30 release, but I couldn't find any specific references to where the tomcat-util.jar file in V4.1.30 originated.) While my little hack appears to be working - I'm still testing the crap out of it - would be nice to know if there is something I may have missed, so any input from those intimate with V4.1.30 V5.x logic would be most appreciated.

Off handed guess -- it means your classes were compiled with a version of a JDK not compatible with the JDK running your Tomcat install.

RE: Tomcat error
Hi, You can have as many versions of the JDK installed on your system as you want. Tomcat will use the one pointed out by the JAVA_HOME variable. Whatever JDK Tomcat uses should be the same or a later version than the JDK you use to compile your class. Class version 49.0 is JDK 1.5 I believe, so if you compile your classes with JDK 1.5 you have to set Tomcat to use JDK 1.5 as well (which is officially not supported yet but actually works fine).

I could really use the functionality, but the only servlet engine I've found that has excellent virtual host support is Caucho's Resin. You can do a trick with Apache rewrite rules to match wildcard domains and forward them to a particular /context-path/.

My problem is, how to secure the connection between apache and tomcat. One idea: you could use mod_proxy as the Apache/Tomcat connection rather than mod_jk, and then configure Tomcat to do SSL. Then Apache and Tomcat are just talking HTTP over SSL; a bit less efficient than mod_jk, perhaps, but probably easier to configure. No idea if mod_proxy can proxy HTTP connections to HTTPS; you might have to force clients to use HTTPS to make it happen. Just a wild idea.

Thanks for your reply, I understand. This is definitely the cause. Shapira, Yoav wrote: Hi, You can have as many versions of the JDK installed on your system as you want. Tomcat will use the one pointed out by the JAVA_HOME variable. Whatever JDK Tomcat uses should be the same or a later version than the JDK you use to compile your class.

RE: Host Aliases, Wildcards
Hi, You can use Apache's mod_rewrite. You can use Tomcat's balancer webapp. You can use other tools to do tricks in this area.

It didn't seem like a trivial rewrite (at least, not being familiar with the rest of the code and the potential ramifications). I could really use the functionality, but the only servlet engine I've found that has excellent virtual host support is Caucho's Resin. You can do a trick with Apache rewrite rules to match wildcard domains and forward them to a particular /context-path/. This works fine, provided you don't want to use ROOT web apps to avoid having a pointless context path in the URL, which I did. :) - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] This e-mail, including any attachments, is a confidential business communication, and may contain information that is confidential, proprietary and/or privileged.

Re: Tomact 5 - Out of Memory
The JVM and Tomcat don't (that I know about), but there are ways for a servlet to continue to eat up memory with out freeing it. Here's just one: Servlet A instantiates some collection like a Hashtable in it's constructor. Servlet A then procedes to add stuff to that Hashtable without removing anything at the end of the request. Next request comes in and because the servlet is pooled between requests, the Hashtable is the same one from the first request and still has all the old stuff from before in it. Servlet A adds even more stuff while servicing this request, but still hasn't removed any of the old stuff by the end of processing. Keep recycling this servlet until the JVM is full and there is no room for anything else. Better yet, multiply this servlet by however threads tomcat had to create to keep up with the request load. Lesson to learn: free any objects explicitly you don't intend to keep around from request to request. --David Jon Doe wrote: From: David Smith [EMAIL PROTECTED] Reply-To: Tomcat Users List [EMAIL PROTECTED] To: Tomcat Users List [EMAIL PROTECTED] Subject: Re: Tomact 5 - Out of Memory Date: Wed, 04 Aug 2004 07:38:57 -0400 I would set JAVA_OPTS in the startup script you're using to start Tomcat.

RE: Intermittent exception during startup (5.0.25)
Hi, Hmm... Well, RealmBase.java:428 can no longer throw an NPE, and the resultsToArray method that replaced the previous line there seems to handle the null case correctly. However, even if this weren't the case, I'm not convinced that this error you're seeing is related to the other exception reported in this thread. The only common thing about them is that they're hard to reproduce. Your error happens during request processing, the original one reported in this thread is during server startup.

JSTL and preloading pool
Hi all I am using JSTL with precompilation (JSPC). I am wondering why the first time I go on a page with JSTL inside, it took longer to display. But when I go on it a second time, it displays as quick as with scriptlet. So I had a look to the code generated by JSPC and I noticed that there is a pool system with reused objects : org.apache.jasper.runtime.TagHandlerPool So my question is : is there a way to preload all that things ? I tried to do : Class cl = Class.forName(dang.www.websnmp.admin.hostgen_jsp); Object obj = cl.newInstance(); Method m = cl.getMethod(_jspInit, null); m.invoke(obj, null); But no amelioration...

Hi, Tomcat is a webserver and can function as such by itself. You don't have to have Apache or IIS or anything in front of it. The DocumentRoot directory is $CATALINA_HOME/webapps/ROOT/, but you should read the Tomcat configuration reference as it's vastly different from Apache.

RE: Tomcat Webserver
Tomcat is capable of server static and dynamic content with out Apache. One of the main benefits to using Apache is to let Apache server the static content and thereby reduce the load on Tomcat. By default, the document roots for your various webapps are in $CATALINA_HOME/webapps/$WEBAPP_NAME . At least that's true of Tomcat 4.1.x. I haven't begun using 5.0.x yet.

RE: [tomcat] Tomcat as Win2k service
Go to the bin directory in the tomcat home directory. There is a bat file named service that will install Tomcat as a service in your machine.

RE: Tomcat as Win2k service
Uhm, did you read the docs at all? http://jakarta.apache.org/tomcat/tomcat-5.0-doc/setup.html Installation as a service: Tomcat will be installed as a Windows NT/2k/XP service no matter what setting is selected. Using the checkbox on the component page sets the service as auto startup, so that Tomcat is automatically startup when Windows starts. For optimal security, the service should be affected a separate user, with reduced permissions (see the Windows Services administration tool and its documentation). -Original Message- From: Java Techie [mailto:[EMAIL PROTECTED] Sent: Wednesday, August 04, 2004 5:55 PM To: Tomcat Users List Subject: Tomcat as Win2k service Hi, I am using Tomcat5 on win2k Professional.

RE: isapi_redirector2.dll - IIS redirecting to multiple Tomcat instances
I'd be interested to hear if anyone has successfully configured a single instance of IIS directing requests to multiple Tomcat instances at all -Original Message- From: Matt Krevs [mailto:[EMAIL PROTECTED] Sent: Tuesday, 3 August 2004 3:33 PM To: '[EMAIL PROTECTED]' Subject: isapi_redirector2.dll - IIS redirecting to multiple Tomcat instances Hi all, I'm using isapi_redirector2.dll to redirect webapp requests on my IIS server to tomcat. Is it possible to make this single redirector redirect requests to different instances of tomcat (depending on uri)? For example, a request to IIS for /app1/ should go to localhost:8080 and a request for /app2/ should go to localhost:8081. I'm using Windows, so if this is possible, what would my registry entries look like (ie: serverRoot key), and what would my workers2.properties look like?

Absolute path to webapp???
How do you specify an absolute path to a webapplication. I don't want to run my webapp from within $CATALINA_HOME/webapps. When I set it up to point to an absolute path outside of the webapps directory, it still looks for it there: Server port=8005 shutdown=SHUTDOWN Service name=DVRSERVICE Connector port=8080 / Engine name=DVRENGINE defaultHost=localhost Logger className=org.apache.catalina.logger.FileLogger / Host name=localhost appBase=/dvr Context path= docBase=/dvr debug=1 reloadable=false/ /Host /Engine /Service /Server THis is the error I am getting: java.lang.IllegalArgumentException: Document base /usr/tomcat/jakarta-tomcat-5.0.27/webapps/dvr does not exist or is not a readable directory - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Expression tag not evaluated inside custom tag body
I'm using the old JDBC tags from the Advanced JSP book, under Tomcat 4.1.29/Apache 2.0.48 on Linux 9. The expression tags are not being evaluated inside my query tag, although the same stuff works under Tomcat 3.2.3. For example, the following JSP snippet will work: database:query update='false' id='test' SELECT ID,Name From User WHERE Zip=96332 /database:query But the following won't: database:query update='false' id='test' SELECT ID,Name From User WHERE Zip=%= strZip % /database:query The %= strZip % shows up in the body text that my custom tag ends up passing to the database. How can I tell Tomcat that the expressions in this text must be evaluated? My TLD for the query tag is as follows: tag namequery/name tag-classtags.jdbc.QueryTag/tag-class body-contentJSP/body-content attribute nameid/name requiredtrue/required rtexprvaluetrue/rtexprvalue /attribute attribute namescope/name requiredfalse/required rtexprvaluetrue/rtexprvalue /attribute attribute nameupdate/name requiredfalse/required rtexprvaluetrue/rtexprvalue /attribute /tag Thanks for any help you can lend!

It didn't seem like a trivial rewrite (at least, not being familiar with the rest of the code and the potential ramifications). I could really use the functionality, but the only servlet engine I've found that has excellent virtual host support is Caucho's Resin. You can do a trick with Apache rewrite rules to match wildcard domains and forward them to a particular /context-path/. This works fine, provided you don't want to use ROOT web apps to avoid having a pointless context path in the URL, which I did. :) - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] This e-mail, including any attachments, is a confidential business communication, and may contain information that is confidential, proprietary and/or privileged.

Tomcat Standard output problem
Tomcat User Group, We are observing frequent crash of Tomcat 4.0.3(Win 2K) while running our web-application. Our web-application uses a JNI(Java native interface) library, we suspect this is causing a access violation exception somewhere. In order to chase it we have put a printf statement in all JNI layer functions. Now the problem is if I run Tomcat from console, I see all the printf and java System.out.println. If I run tomcat as Windows NT service, I don't see printf statement in log files. Although I can see Servlet's System.out.println output in stdout file. Does tomcat container blocks the printf of JNI layer. Many thanks, Rohit. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

There are loads of emails on the list regarding this. This issue is common enough you should be able to google the archives for details and get loads of responses. Fair point -- if you haven't enough memory overhead, then until the garbage collector kicks in to free objects up you will have a problem. Also as others have suggested, check your code for memory leaks -- especially if it's not under load when it dies. But hey, I thought one of the big selling points is that Java DOES NOT LEAK! Am I mistaken? Isn't it's absence of pointers its big plus? If it does leak then changing the heap size is going to be irrelevant. No matter how large you set it it will bite you in the bum eventually! --David _ Tired of spam?
