A few things I can think of off the top of my head:
It would be interesting to see what the log output is with DEBUG cranked up - it \
should show all the JVM args passed in before the JVM is created. Also I see you're \
logged in as root - is collectd running with sufficient permissions? Can you confirm \
the class is actually in the jar file: jar tf \
/usr/share/collectd/java/collectd-api.jar

Subject: [collectd] Java plugin - Cannot find the API class \
"org.collectd.api.Collectd"
Hi,
I'm running collectd 5.04 on AWS:
collectd-5.0.4-1.19.amzn1.x86_64
collectd-java-5.0.4-1.19.amzn1.x86_64
I'm trying to get the java plugin working to monitor tomcat. I have a config file as \
follows:
LoadPlugin java
<Plugin "java">
JVMARG "-Djava.class.path=/usr/share/collectd/java/collectd-api.jar:/usr/share/collectd/java/generic-jmx.jar"
LoadPlugin "org.collectd.java.GenericJMX"
<Plugin "GenericJMX">
# Heap memory usage
<MBean "memory-heap">
ObjectName "java.lang:type=Memory"
InstancePrefix "memory-heap"
<Value>
Type "jmx_memory"
Table true
Attribute "HeapMemoryUsage"
</Value>
</MBean>
<Connection>
Host "localhost"
ServiceURL "service:jmx:rmi:///jndi/rmi://localhost:17264/jmxrmi"
Collect "memory_pool"
</Connection>
</Plugin>
</Plugin>
The log file says: Cannot find the API class "org.collectd.api.Collectd". Please set \
the correct class path using 'JVMArg "-Djava.class.path=..."'
But as you can see, I already have this line added. The jar files exist and contain \
the correct classes:
[root@localhost ~]# rpm -ql collectd-java
/etc/collectd.d/java.conf
/usr/lib64/collectd/java.so
/usr/share/collectd/java/collectd-api.jar
/usr/share/collectd/java/generic-jmx.jar
Can anyone help?
Thanks,
Dan Scott
