Monitoring page takes a long time to load when huge number of threads

We have a Tomcat server with upwards of 20,000 threads due to long polling. 
Unfortunately we are no longer able to load the monitoring page because it 
takes almost a minute to load, and during loading stalls other requests in the 
web app.

I took a thread dump at the time of loading, and found what I think is the 
thread that generates the report .. not sure if this is helpful though:

Distributed (XA) Transactions aborted by 'rollback' in JavaINformations.java

What steps will reproduce the problem?
1. Create a JNDI database using a distributed transaction manager (e.g. 
Atomikos).
2. Attempt to access and update the database
3. The updates will fail

What is the expected output?
Distributed transactions should succeed.

What do you see instead?
They fail (are rolled back due to the resource being engaged in a 'local' 
transaction outside of the transaction manager.

' 
raised -9: the XA resource is currently involved in a local (non-XA) transaction


What version of the product are you using? On what application server, JDK,
operating system?
Linux RHEL 5.5, fully up-to-date
JDK:
java version "1.6.0_21"
Java(TM) SE Runtime Environment (build 1.6.0_21-b06)
Java HotSpot(TM) 64-Bit Server VM (build 17.0-b16, mixed mode)

Javamelody 1.18.0


Please provide any additional information below.
Looking at the source code it appears that JavaInformations.java calls 
'rollback' in the buildDataBaseVersion function.
This isn't necessary as all the code does is query the connection
based meta-data.

Instead, a simple close (to return the connection to the pool) is sufficient.

This would only effect XA transactions anyway.

Improve extendability (customize "name" in spring statistics)

It would be nice if this method:
private static String getMonitorName(MethodInvocation invocation) {
in MonitoringSpringInterceptor

could be protected.
Then I could override it and add contextual information to the the monitor name.

Performance improvements for heavily loaded servers

We are using JavaMelody for a server running thousands of threads (many are 
Comet-style long polling threads) and it's working great, but starting to get a 
little slow. The monitoring page can run into the megabyte range, and it causes 
the JS interpreter of the web browser to block.

The culprits seem to be the Threads and Current Requests sections, which can 
contain thousands of entries.

Some suggestions:

* Make it possible to omit or load the Threads and Current Requests sections 
separately
* Make sections or individual entries load dynamically
* Compress stack traces (they share much of the same text, so may be easily 
compressable)

Quartz job CRON expression with '#' causes NullPointerException

What steps will reproduce the problem?
1. create Quartz task
2. schedule this task/job with a cron expression
3. use a cron expression containing a '#' character, e.g. "0 0 10 ? * 7#1" 
(meaning like 'fire at 10am on 1st Saturday of each month')

What is the expected output?
I expected the list of all 'Jobs' followed by the 'Data caches'.

What do you see instead?
The Java Melody page was built until the point where the NullPointerException 
occurred while writing CRON expression "0 0 10 ? * 7#1".

What version of the product are you using?
Since the CRON expressions have been introduced with Java Melody 1.15.0, it 
occurs in 1.15.0, 1.16.0 an 1.17.0-SNAPSHOT.

On what application server, JDK,
operating system?
- JBoss 4.2.3
- JDK 1.6.0_20 (64bit)
- Fedora Core 13 (64bit)

Please provide any additional information below.
I will attach a screenshot and then append an SVN patch for class 
HtmlJobInformationsReport.
But here the stack trace at first with some additional debug from myself:

Grails-melody plugin breaks the filterpane plugin

I'm not sure if this is a filterpane problem or grails-melody, but I
couldn't see a way of switching off the proxying for the affected class. 

What steps will reproduce the problem?
1. In a grails project, install + configure the filterpane plugin
> grails install-plugin filterpane
2. Configure a filter (following http://www.grails.org/plugin/filterpane)
3. Activate a filtered view and see it work
4. Install grails-melody
> grails install-plugin grails-melody
5. Re-try the filter and see a stacktrace with e.g.

Quartz errors break down the frontend

Quartz stores jobs in the database with Java class information. The problem 
occurs if the Java code changes and the class information in the database refer 
to deleted and/or renamed classes. 

What steps will reproduce the problem?
1. Configure an unknown class in the Jobs table of Quartz
2. Startup the server with JavaMelody

What is the expected output? What do you see instead?
I would assume that these jobs are ignored by the frontend or listed with an 
error status. Instead the frontend shows a "HTTP status 500" with the following 
root cause (Stack trace is attached below.

What version of the product are you using? On what application server, JDK,
operating system?
JavaMelody 1.19.0 on JBoss 4, Linux

I hope that this helps to improve this wonderful tool!

Thanks in advance!

Christian

NumberFormatException requesting process information

When requesting OS process information on a Windows machine on 1.18.0, I get 
the following stack trace. The system pops up a message in a dialog box then 
refreshes the page, so its not a serious problem. Just thought I'd relay the 
message. Great project BTW :D

JavaMelody Grails Plugin block the JQuery AJAX call output

I am using Grails 1.3.2 and JQuery provider, the AJAX calls was working fine, 
after I install the Grails-Melody 0.3 version, modify the web.xml template 
according to your doc adding filter etc. The Melody works great and the normal 
http request/response are working great too. However, all the Ajax call can not 
produce output on page. I debug and see that the call has actually hit the 
server, but don't know why the response can not get to the page.

Disk time and network time monitoring

Would it be possible to add disk mean time and network mean time monitoring to 
the JSP statistics (and http statistics if possible)?

I'm still investigating performance problems with jira. What I see is that some 
jsp requests take ~5000ms mean time, 350ms cpu time and 100ms sql time. I can 
install a more powerful profiling tool on a test server but obviously the 
traffic there is very unrealistic. So I need to understand where most of the 
time goes. This server has 4 processors and the mean active thread count is ~2 
I don't think the huge difference comes from there just being too many active 
threads.

What steps will reproduce the problem?
1. Copy the jar into the webapp/WEB-INF/lib folder
2. Start Bamboo
3. Tail the bamboo log file

What is the expected output? What do you see instead?

My Bamboo logs show this stack trace when I install javamelody in Bamboo 2.6.1:

I can´t view the "Used Memory"

What steps will reproduce the problem?
1. i install and config the monitor in my "suviSC" application, but i see
that the servlet activation its no showed in user guide i find the Class
CollectorServlet in jar file and i add this class to support Serlvet i add
the next lines in web.xml (tomcat 6 on windows xp and javamelody 1.11.1)

    <servlet>
        <servlet-name>MonitoringServlet</servlet-name>
        <servlet-class>
            net.bull.javamelody.CollectorServlet
        </servlet-class>
        <load-on-startup>1</load-on-startup>
    </servlet>

  <servlet-mapping>
    <servlet-name>MonitoringServlet</servlet-name>
    <url-pattern>/monitoring</url-pattern>
  </servlet-mapping>

Without this lines the monitor doesn´t show statistics i don´t understand
why this config its not included in user guide.


2. After the config i access the url
http://localhost:8080/suviSC/monitoring and i see the numerical statistics
but when i open the "Used Memory" i don´t see graphics results. (i attach
the image with the results)
3. I review the stdout log file and i see 2 errors:

3.1 the first error is on startup the details is:

the JIRA report should be visible for admins only

When installing the JIRA plugin (1.14) the report is visible for everybody
without login. Because it contains lots of internal information the report
should be accessible by JIRA administrators only.

Refreshing /monitoring page causes used jdbc connections leak if installed as jira plugin

What steps will reproduce the problem?
1. Install as Jira plugin.
2. Refresh /monitoring page 10 times.
3. Observe that used connections number grew by ~10. After 10 hours the
used connections are still there even if there's 50 of them.

What is the expected output? What do you see instead?
Number of used connections should decrease over time.

What version of the product are you using? On what application server, JDK,
operating system?
jira-javamelody-1.15.1.jar
jira 4.0.1

Please provide any additional information below.

Unreasonable values for sql monitoring

Sorry for not being able to provide a test case, but been helping a company out 
with some performance testing and getting unreasonable values in the sql 
output. Provided a screenshot 

What is the expected output? What do you see instead?
The values for "max time ms" for ("exec sp_session_starta 60","exec 
sp_session_forlang") is 156 298 ms/ 169 511 ms. Shouldn't be possible with that 
high values since the maxtime for serving the whole jsp pages is just 
14 266 ms. 

What version of the product are you using? On what application server, JDK,
operating system?
Jdk1.6, mssql server 2005, Windows server 2003. Javamelody 1.19.0. 

Any ideas what the causes could be for these values. The total page for 
accessing the jsp pages is just a few seconds.

Tomcat crushed ("deployment on Tomcat without modification of monitored webapps", beta feature)

What steps will reproduce the problem?
1. The environment I am using is a VPS running CentOS 5.3, java version
1.6.0_12, apache 2.2.14 with mod jk 1.2.28, tomcat 6.0.20 and
mysql-connector-java-5.0.6

2. Installed javamelody as descriped in "UserGuideAdvanced/Deployment on
Tomcat without modification of monitored webapps"


What is the expected output? What do you see instead?
Some parameters, mainly concerning jdbc connections, where never properly
monitored. In catalina log got many Exceptions concerning bad timestamps
caudes by JRobin (i have deleted original log file from the production
server). After letting javamelody installed after two days log file became
12GB! so i had to delete it, not to mention that for more than 8 hours
tomcat was on DoS state. 

What version of the product are you using? On what operating system?
javamelody 1.10.0 and as i mentioned above CentOS 5.3

Please provide any additional information below.

I have a standalone email worker class with lot of closures, the closure and a 
map will be past to a thread as parameters to do backend job. These had been 
working fine without Grails-Melody plugin. 

Here are the detail error:

http status 500 (getPID)

What steps will reproduce the problem?
1. The environment I am using is two physical servers: one with apache 
with mod jk and another with tomcat 5.5.25 where the jmelody is deployed.

What is the expected output? What do you see instead?
I tested it in an environment where there was no apache as the gateway to 
tomcat web apps and I got the result page /context/monitoring.  But after 
deployig to the new environment(UAT) I see status code 500 with the 
following stack trace:

java.util.NoSuchElementException
    java.util.StringTokenizer.nextToken(StringTokenizer.java:332)

What version of the product are you using? On what operating system?
JavaMelody1.8.2, Tomcat 5.5.25, JDK 1.5.0_19

Please provide any additional information below.
Based on the PID request I am assuming its the jk thats causing the 
problem.  The environment as is currently setup does not allow direct 
(external) connection to tomcat, i.e. all the requests go through JK.  
Furthermore this is the message being logged in catalina.out:

jira plugin displays only garbage characters

On some JIRA instances, when the /monitoring page is accessed, only random
characters are displayed instead of the diagrams.

This is caused by JIRA's gzip compression.

Workaround:

Turn off gzip compression by changing the "Use gzip compression" setting in
JIRA's "General Configuration" dialog
(http://localhost:8080/jira/secure/admin/jira/ViewApplicationProperties.jspa)

Null pointer with jm 1.14.2 and jira 4.0.1

After installing javamelody 1.14.2 on Jira 4.0.1 it worked for 10 minutes
and then suddenly the monitoring page doesnt open anymore and gives the
attached error instead.

So I installed javamelody 1.14.0 thinking it might be a new issue and it
seemed to work ... for 10 minutes. Now it gives the same error.

When I restart tomcat the error doesnt take 10 minutes to appear. Its there
right away. Looked around in the logs. Found only the same error, nothing
else related to javamelody.

Ill try switching to an even earlier version now to see if it works.

Javamelody giving errors after deploy

What steps will reproduce the problem?
1.Add the necessary lines in web.xml
2.Add the Javamelody.jar /  jrobin-x.jar,  and itext-2.1.7.jar under lib
3.Deploy Javamelody.war

What is the expected output? What do you see instead?
It should start without giving any error. Yet in my catalina.out I see the 
following errors:

GRAVE: A web application appears to have started a TimerThread named
[javamelody javamelody] via the java.util.Timer API but has failed to stop
it. To prevent a memory leak, the timer (and hence the associated thread)
has been forcibly cancelled.


What version of the product are you using? On what application server, JDK,
operating system?
1.15.0

Please provide any additional information below.

SQL requests are not monitored and "jdbc connections" are always 0, when JndiObjectFactoryBean is used in Spring

What steps will reproduce the problem?
Use of JndiObjectFactoryBean in spring context file like the one below,
referencing a datasource defined in the JNDI context of the application server:
    <bean id="dataSource"
        class="org.springframework.jndi.JndiObjectFactoryBean">
        <property name="jndiName"
            value="java:comp/env/jdbc/TestDB" />
    </bean>
It is supposed that the spring init is done before javamelody's filter and
listener init.

What is the expected output? What do you see instead?
In javamelody reports, sql requests are not monitored and "jdbc
connections" are always 0 in charts and in "system informations".
But the database version and the jdbc driver version are correctly
displayed in "system informations" in the reports.

support tomcat jdbc pool

I saw in JdbcWrapper that you have support for 
org.apache.tomcat.dbcp.dbcp.BasicDataSource and 
org.apache.commons.dbcp.BasicDataSource

Can you please add support for org.apache.tomcat.jdbc.pool.DataSourceFactory 
which is the new tomcat jdbc pool, see doc here : 
http://people.apache.org/~fhanik/jdbc-pool/jdbc-pool.html

thanks

StackOverflow Exception

This stackoverflow exception is triggered by a call to a log4j's
log.warn("...") function inside the JIRA getUser() function. When the log4j
warn function is executed, it is intercepted by JavaMelody for some reason.
JavaMelody attempts to find the user name of the currently logged in user
by calling getRemoteUser(), which in turn calls getUser(), shich calls
warn(), which is intercepted by JavaMelody and so on.

Workaround: turn off any logging for the class containing the log4j warn
function (in this case, it is the
com.pixelpark.seraph.SSOAuthenticator.getUser function in a SSO plugin for
JIRA).

This is a severe problem that should be fixed because large JIRA instances
would benefit most from using JavaMelody, but at the same time these large
instances often have additional login code such as SSO plugins, Active
Directory plugins, Crowd connector etc).

Other software products that override getRemoteUser() and use logging
statements would suffer from the same problem.

no sql requests when using jdk1.6, a recent jdbc driver and net.bull.javamelody.JdbcDriver

Sql requests are not monitored, when you use the JDK or JRE v1.6 and a recent 
jdbc driver including a "META-INF/services/java.sql.Driver file", such as an 
oracle 11g jdbc driver (ojdbc6.jar or ojdbc5.jar), and if you use the 
net.bull.javamelody.JdbcDriver of JavaMelody v1.18.0 and not a jdbc datasource.

JDBC properties are correctly written in hibernate.cfg.xml as said in

2. Stop application server
3. Wait some time until the trigger fire times have been exceeded
4. Start application server
5. Have a look into the server log file

What is the expected output? What do you see instead?
I would have expected the Quartz jobs to be recovered or started because they 
missed their fire times. This works fine until javamelody 1.14.0.
Anyway, I receive following exception for each recovered job (different job 
name of course):


2010-06-29 16:41:57,379 ERROR (MyQuartzScheduler_Worker-2:)

What version of the product are you using? On what application server, JDK,
operating system?
- JavaMelody 1.17.0
- JBoss 4.2.3
- JDK 1.6.0_20 (64bit)
- Fedora Core 13 (64bit) and SLES 10 (64bit)

Please provide any additional information below.
In our application this causes the jobs to be hanging. Javamelody shows a red 
bar and that the jobs would running, but they are not. They hang. I simply 
replaced the javamelody-1.17.0.jar with javamelody-1.14.0.jar and it worked 
fine again - though memory histogram does not work for us with javamelody 
1.14.0...

serious memory leak (with an Atlassian JIRA server)

I have javamelody installed on jira 3.13.2 for a few weeks. At first I
didnt notice the problem but it has been growing ever since. 

I did some profiling with YourKit. Look at the attached files. I think the
big growing spikes during the night and so on are caused by javamelody.

I dont know what information you need so contact me: [email protected]
