Re: [EXT] Datadog _ JMX Integration facing connection issues.
Hello chris,
thanks for adding a point and I may have missed your email.
below is some of the points, which showed me how tomcat is being started in my
application.
* Line 19: INFO [main][2023-12-27 09:00:38,983] -

to launch tomcat, we are not using any command here, I am trying to build my
code to an image, making some helm chart out of it, using helm chart to install
in my AKS containers.
Thanks & Regards,

How are you launching Tomcat itself? Are you using catalina.sh or
something similar, or do you use some kind of embedded-launch?
It sounds to me like using CATALINA_OPTS is causing Tomcat not to start
at all. If you use JAVA_TOOL_OPTIONS (which Tomcat ignores), Tomcat will
start but won't initialize JMX in the way you want it to.
The solution is to look at the log files that are produced when Tomcat
launches (or fails to launch). Are you able to observe those?
It would be great to see the exact command Helm (or whatever) uses to
attempt to launch Tomcat, and then the stdout/stderr of that attempt.
The diagnostic messages shown when a JVM refuses to start are usually
pretty good. Same thing with Tomcat, though Tomcat usually starts even
if e.g. no connectors are successfully started because there is no
actual requirement for Tomcat to listen to any ports.

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

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

Good question. What is pid #1? Do those port numbers make any sense for
your Tomcat-based service?
Is Tomcat even running? Try 'ps aux | grep catalina' to see if there are
any. Are you launching Tomcat using catalina.sh / startup.sh or similar?
Or are you running Tomcat "embedded" within your own application?

Re: [EXT] Re: Datadog _ JMX Integration facing connection issues.
Hey Christopher.,
Greetings of the day.
1.
Might I have confused you with posting the arguments directly ., Yeah as i just
shared you the annotations with comments , to state you the stuff i am using.,
But in my deployment ., I am using them in catalina opts., and trying to call
them from values.yaml., which looks like this :
javaVMMemoryArgument: "-Xms2048M -Xmx10240M -XX:+UseStringDeduplication
-XX:+UseContainerSupport -Dcom.sun.management.jmxremote
-Dcom.sun.management.jmxremote.authenticate=false
-Dcom.sun.management.jmxremote.ssl=false
-Dcom.sun.management.jmxremote.local.only=false
-Dcom.sun.management.jmxremote.port=49151
-Djava.rmi.server.hostname=lab1workflow4scalsvc2zus1-service.hqm-lab1.svc.cluster.local
"
and I am referring the word "javaVMMemoryArgument" from values yaml and
calling it in Catalina_opts, so that it would fetch all these
annotations as mentioned above, during the deployment. This is my deployment
part., where I am referring to the above values from values.yaml
env:
- name: CATALINA_OPTS
value: {{ .Values.deployment.javaVMMemoryArgument }}
1.
Coming to Process., I have searched for Java process that listens on my
mentioned port ie., 49151, but none of the process is listening to that process.
I even tried with
root@lab1workflow4scalsvc2zus1-deployment-fd64ff775-cwzn6:/# netstat -tulpn |
grep LISTEN

which confirms me that , any of the process is being listening on the port
49151.

If that's YAML, then all of the above is comments. Those lines do nothing.

You should definitely use CATALINA_OPTS and none of the other things you
mention, here. Specifically because of the port issues. JAVA_TOOL_OPTS
don't affect Tomcat at all are useless for you. JAVA_OPTS affects all
Tomcat-related scripts, and you'll find that even "shutdown" causes an
error... because it's trying to initialize JMX when shutting-down, which
is again useless.

Re: [EXT] Re: Datadog _ JMX Integration facing connection issues.
Hello Christopher.
Thanks for the response!
Let me walk you through the Environment.,
I have a cluster and I am installing multiple microservices in the cluster. And
one of the microservices I am integrating the JMX on of the microservices.,
and the mentioned IP of the pod is being changed dynamically after each
deployment .
Here are the annotations that I am using in my deployment:
- name: JAVA_OPTS
# value: >-
# -Dcom.sun.management.jmxremote
# -Dcom.sun.management.jmxremote.authenticate=false
# -Dcom.sun.management.jmxremote.ssl=false
# -Dcom.sun.management.jmxremote.local.only=false
# -Dcom.sun.management.jmxremote.port=49151
# -Dcom.sun.management.jmxremote.rmi.port=49151
#
-Djava.rmi.server.hostname=lab1workflow4scalsvc2zus1-service.hqm-lab1.svc.cluster.local
as i said , I have implemented these in three scenarios., Catalina_opts /
Java_opts / Java_Tool_opts
I have tried deploying catalina_ots and Java_opts as in the case of above
mentioned.
I also tried other way, mentioning all these in the values.yaml file ( I am
using Helm Deployment to upgrade my deployments) and referring these
annotations as , and mentioning them in the Value
env:
- name: CATALINA_OPTS
value: {{ .Values.deployment.javaVMMemoryArgument }}
getting netstat output from my pod:
root@lab1workflow4scalsvc2zus1-deployment-fd64ff775-cwzn6:/# netstat -tulpn
Active Internet connections (only servers)

right now , I am passing my args with Catalina_opts in my deployment and I am
not able to get any tomcat process pid while i check with netstat -apn , I can
see multiple Java Process but not single tomcat process
My Jmx port is being configured as a service., so that it could be bounded with
Tcp protocol externally to the container., and allow all tcp connections.
Hope I am able to provide you some detailed information.,
Please let me know., if I can help you with anything in further!

Right: the DataDog server is unable to connect to your appication via
JMX. I'm assuming that 10.75.12.136 is the IP where Tomcat is running,
and that DataDog isn't running on that server. It's on some other IP, right?

What is your exact CATALINA_OPTS value (masking any secrets that may be
in there).
Is Tomcat definitely running? Can you prove that with a "ps" listing,
for example? That will also confirm it's running with the proper
CATALINA_OPTS settings.
Can you run "netstat" and show all of the ports your Tomcat process is
listening t

Re: [EXT] Re: Datadog _ JMX Integration facing connection issues.
Hello Chris. Thanks for the response.. as you suggested., I tried adding my annotations in CATALINA_OPTS., Instead of Java_Opts and Java_tool_options., But its not even working out., Java process is not getting created., and port is not bound to any process. Let me know if I am missing anything.

You will probably want to use CATALINA_OPTS instead of any of the other ones. JAVA_TOOL_OPTS isn't an environment variable regognized by Tomcat. You certainly don't want to use JAVA_OPTS, because Tomcat uses JAVA_OPTS any time it invokes a JVM. For example, running bind/digest.sh doesn't need to have the JMX subsystem starting-up and trying to grab a port. JAVA_TOOL_OPTS is an environment variable used by JVM-launching processes, like jps for example... > yeah they are reflecting and creating a Java Process. > but I am facing a problem here., while i am checking JSP, Thats : the port i > am using here to enable JMX is been opening a process with the mentioned port > and at the same time shows port is being used.: > > root@lab1workflow4scalsvc2zus1-deployment-577d856494-ftb22:/# jps > Picked up JAVA_TOOL_OPTIONS: -Xms2048M -Xmx10240M -XX:+UseStringDeduplication > -XX:+UseContainerSupport -Dcom.sun.management.jmxremote > -Dcom.sun.management.jmxremote.authenticate=false > -Dcom.sun.management.jmxremote.ssl=false > -Dcom.sun.management.jmxremote.local.only=false > -Dcom.sun.management.jmxremote.port=49151 > -Djava.rmi.server.hostname=tomcat.default.svc.cluster.local > -javaagent:/datadog-lib/dd-java-agent.jar > -XX:OnError=/datadog-lib/continuousprofiler/tmp/dd_crash_uploader.sh > -XX:ErrorFile=/datadog-lib/continuousprofiler/tmp/hs_err_pid_%p.log > Error: Exception thrown by the agent : java.rmi.server.ExportException: Port > already in use: 49151; nested exception is: > java.net.BindException: Address already in use (Bind failed) Yes: you have set JAVA_TOOL_OPTS and then run jps. jps is trying to bind to your port which is aready bound by your Tomcat process. The solution is to use only CATALINA_OPTS to set these options. -chris - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
