Hai Chuck.,
Thanks for jumping in.,
thats what my concern is.
as previously added by Chris, I have added my annotations in Catalina_opts .,
Which is preferred by Java_Process for adding the annotations., But Here by
using catalina_opts., they are not reflecting.
where as adding them in java-tool-options., Makes a process with Tomcat and a
process that listens on the mentioned port., but throws port is already
binded., as its an environment variable, its already looking for a port, where
as its already created., throws binding error.
Yesterday ., I thought of adding both the formats, adding java_tool_opts and
Catalina opts., inorder to utilize the previous thigns., as below
- name: JAVA_TOOL_OPTIONS
value: {{ .Values.deployment.javaVMMemoryArgument }}
- name: POD_IP
valueFrom:
fieldRef:
fieldPath: status.podIP
- name: CATALINA_OPTS
value: >-
-Dcom.sun.management.jmxremote
-Dcom.sun.management.jmxremote.port=49151
-Djava.rmi.server.hostname=$POD_IP
-Dcom.sun.management.jmxremote.authenticate=false
-Dcom.sun.management.jmxremote.ssl=false
-Dcom.sun.management.jmxremote.local.only=false
-Xms2048M -Xmx10240M
Java_tool_opts are as : -XX:+UseStringDeduplication -XX:+UseContainerSupport
-Dcom.sun.management.jmxremote
just added to initiate a JMX process.,
but nothing is working out.,
I would like to request you for further inputs

That shows only the grep process looking for catalina, not anything using
catalina. If Tomcat were actually running, you’d see something like this
(slightly reformatted for clarity):
