[Jamonapi-info] Spring and JMX ?

[Cedric B. <ce...@ag...>]

Hi,

I've integrated Jamon in my Spring application using
the JamonPerformanceMonitorInterceptor. I can see my beans metrics in the
Jamon.war application.

Is there a way of registering these metrics via JMX, so can see it using
Jconsole.


Cheers,
Ced.

[Jamonapi-info] Integrate JMon with JBOSS EAP 6

[ahsan s. <ahs...@gm...>]

Hi All,

I am trying to integrate Jmon with JBOSS EAP 6.4. I have followed following
links[1][2].  When I start jboss , Iam getting a class not found exception
as follows.

*Caused by: java.lang.NoClassDefFoundError:
org/apache/catalina/valves/ValveBase *


After that, I have included this module in Jboos Modules under org.apache.
Then I am getting a class cast exceptio as follows.

*Caused by: java.lang.ClassCastException:
com.jamonapi.http.JAMonTomcatValve cannot be cast to
org.apache.catalina.Valve*

What is the reason for this? Is there anyway to resolve this? Otherwise, is
there any alternative ways to integrate JMon with JBOSS EAP 6.4. Please
help me.

[Steve S. <jam...@gm...>]

JAMon 2.74 was released today.  It is a minor release.  The changes follow:

   - New methods allow you to limit the number of monitors (in previous
   versions this could already be done for page hits)
   - You can also tell the total size of all the label strings and take
   action like MonitorFactory.reset() if they become too big
   - See these methods for more info:
   - MonitorFactory.setMaxNumMonitors(maxMonitors);
      - MonitorFactory.getMaxNumMonitors();
      - MonitorFactory.enableTotalKeySizeTracking();
      - MonitorFactory.disableTotalKeySizeTracking();

[Jamonapi-info] JAMon 2.72 Released Today

[Steve S. <st...@li...>]

JAMon 2.72 was released Today.  JAMon 2.72 is a minor release.  It now
requires JDK 1.5 or higher however.  If you are upgrading from JAMon 2.7 or
lower you will also need to upgrade the JAMon war file

The following is a list of changes in this version:

- Nanosecond timing is now available - The MonitorFactor now contains a
startNano method that times things in nanoseconds as opposed to the default
value for the start method which still uses  milliseconds. Note for most
performance testing for business applications milliseconds is optimal.
- New Operating System Monitoring - A cool new ability to monitor anything
on your OS such as your scripts. Call jstart/jstop/jadd scripts from your
unix/linux/mac host and time and measure aspects of your operating system
like script execution time, backup times, cpu utilization, and free memory
to name a few. See the new JAMon videos on the home page for more
information on how OS Monitoring works
- Monitor skip() method bug fix - The newly added monitor skip method was
incorrectly calculated Max active and Avg active.  Both of these were
fixed.
- 3 New videos were placed on youtube - These videos show how JAMon works.
The videos are each a few minutes long.  The videos are JAMon 101, JAMon
reporting, and JAMon operating system monitoring.  Video links follow:

   1. JAMon 101 <http://www.youtube.com/watch?v=fKooex0ZPcw> - An intro
   video to JAMon. Shows how to use start/stop/add and also other highlights of
   using JAMon.
   2. JAMon GUI <http://www.youtube.com/watch?v=BfIuoy8mP5c> - Shows how to
   access the information in JAMon via the JAMon WAR. Also shows data captured
   by the JAMon servlet filter and JDBC Proxy driver.
   3. JAMon Operating System
monitoring<http://www.youtube.com/watch?v=Drf3d9m5zss>- Monitor your
unix/linux/mac scripts with JAMon. Introduced in JAMon 2.72.

[Jamonapi-info] JAMon 2.71 Released Today

[Steve S. <st...@li...>]

JAMon 2.71 is a minor release that adds a few features that users requested
after version 2.7 (Thanks for patiently waiting!). JAMon still requires JDK
1.4 or higher (with a couple exceptions referenced below). If version 2.7 is
working for you and you don't want the features below then this is not a
required upgrade. To use 2.71 you must install the new jar (jamon-2.71.jar),
and if you are using using JAMon war to view the JAMon stats then you must
also install the new war.

[Jamonapi-info] Can't disable DEBUG in JAMonAppender

[robert l. <rob...@gm...>]

Hi all,

First of all - great project. I'm trying to get only ERROR and above
messages in some type of screen view. I'm using jboss 4.0.5 on linux. I have
these entries:

 <appender name="JAMONAPPENDER" class="com.jamonapi.log4j.JAMonAppender">
     <param name="EnableListeners" value="BASIC"/>
     <param name="generalize" value="true"/>
     <layout class="org.apache.log4j.PatternLayout">
       <param name="ConversionPattern" value="%p.%c-%m"/>
     </layout>
  </appender>

My understanding is that will give me WARN and above, but in the
jamonadmin.jsp view I get a bunch of DEBUG statements. I've also tried:


 <appender name="JAMONAPPENDER" class="com.jamonapi.log4j.JAMonAppender">
     <param name="EnableListeners" value="FATAL"/>
     <param name="EnableListeners" value="ERROR"/>
     <param name="generalize" value="true"/>
     <layout class="org.apache.log4j.PatternLayout">
       <param name="ConversionPattern" value="%p.%c-%m"/>
     </layout>
   </appender>

But I still get DEBUG statements in the jamonadmin.jsp view. Any ideas?

Also, what is the param name to increase the N size past 100 (haven't looked
into the source yet ;-) ) .

Robert
