[collectd] java plugin load issue

[martin]

Hi Poil,

You were spot on I did this a few days ago and it showed that libjvm.so was not found i.e. broken. 


The problem was that I was using the Oracle JDK instead of the OpenJDK installation.


What I've done is modify my existing tomcat  installation to point to the Oracle JDK and install the Java 1.7 OpenJDK and let collectd use that.


Cheers


-Martin

  Hi all,   
 
 
 
 
 I wonder if someone can help me I'm migrating from jmxtrans to collectd-java/genericjmx, I've configured it as follows but I'm getting a "Found a configuration for the `java' plugin, but the plugin isn't loaded or didn't register a configuration callback." error
 
 
 ---Start Here
  # cat collectd5.conf
 BaseDir     "/var/lib/collectd5"
 PIDFile     "/var/run/collectd5.pid"
 LoadPlugin syslog
 LoadPlugin cpu
 LoadPlugin interface
 LoadPlugin load
 LoadPlugin memory
 Include "/etc/collectd5.d/*.conf"
 
 
 # cat collectd5.d/graphite.conf 
 LoadPlugin write_graphite
 
 
 <Plugin write_graphite>
   <Carbon>
     Host "myhost1"
     Port "2003"
     Prefix "collectd."
     StoreRates false
     AlwaysAppendDS false
     EscapeCharacter "_"
   </Carbon>
 </Plugin>
 
 
 # cat collectd5.d/genericjmx.conf 
 LoadPlugin java
 
 
 <Plugin "java">
   JVMARG "-Djava.class.path=/usr/share/collectd/java"

         Type "memory"
         #InstancePrefix ""

       </Value>

       Host "vmapp1"
       Collect "memory_pool"
     </Connection>
   </Plugin>
 </Plugin>
 
 --end here
 
 
 I've got collectd-java and multiple versions of java installed i.e.
 
 
 # rpm -ql collectd-java
 /usr/lib64/collectd/java.so
 /usr/share/collectd/java
 /usr/share/collectd/java/collectd-api.jar
 /usr/share/collectd/java/generic-jmx.jar
 /usr/share/man/man5/collectd-java.5.gz
 # rpm -qa | grep -i -e java -e jre -e jdk
 collectd-java-5.1.0-1.el6.x86_64
 java-1.7.0-openjdk-1.7.0.3-2.1.el6.7.x86_64
 java-1.5.0-gcj-1.5.0.0-29.1.el6.x86_64
 jre-1.7.0_07-fcs.x86_64
 java-1.6.0-openjdk-1.6.0.0-1.45.1.11.1.el6.x86_64
 gcc-java-4.4.6-3.el6.x86_64
 jdk-1.7.0_07-fcs.x86_64
 
 
 but I get the following errors:

 Nov  1 17:33:14 ip-10-39-3-223 collectd[20809]: Found a configuration for the `java' plugin, but the plugin isn't loaded or didn't register a configuration callback.

  # collectd5 -t
 Could not find plugin java.
 # collectd5 -T

 Can anyone help me fix this?
