Hi, We have instrumented glowroot aget on 1 of the JAVA jboss server. we have followed the standard steps to instrument the agent in this application

Instrumentation path :- JAVA_OPTS="-javaagent:/home/mapp/glowroot-agent/glowroot.jar -Xms1303m -Xmx1303m ..."

Instrumented in :- standalone.sh File

Please find the below error for same & let me know if you need more information.

JAVA: /app/soft/jboss/jdk1.8.0_92/bin/java

Thanks for reporting this. What version of JBoss are you using?

[trask]

Also, what is the full line "Error: Could not find or load main class ..."? Thanks

Hi Trask,

Thanks for your quick response. We are using JBOSS wildfly-9.0.1.Final_1 for this configuration. there is nothing after this error message.

Could you please provide the compatibility metrics for all java components while doing instrumentation.

Thanks & Regards, Vijay.

[trask]

Thanks, can you also attach your standalone.sh file?

[vijayninave]

nohup.zip Hi Trask,

Requested file has been attached here. This included standalone.sh as well as app log file.

Kindly let me know if you need more information.

Regards, Vijay Ninave

I don't see glowroot in the attached standalone.sh? Thanks

[vijayninave]

We have removed the glowroot instrumentation as the application was not getting up. could you please suggest, where we can put the path for same and also let us know is there any steps which we missed for this instrumentation.

Regards, Vijay.

[trask]

Can you post a copy of standalone.sh when it had glowroot in it?

[vijayninave]

standalone.zip Hi Trask,

Please find the attached file for your reference. Accordingly please let me know where we can put the path or the existing one is correct. apart from that is there anything we need to update.

Regards, Vijay.

Thanks, it looks like your JAVA_OPTS assignment is mixed up in the echo statements. Can you fix this and try again?

echo "========================================================================="
echo ""
echo "  JBoss Bootstrap Environment"
echo ""
echo "  JBOSS_HOME: $JBOSS_HOME"
echo ""
echo "  JAVA: $JAVA"
echo ""
echo "  JAVA_OPTS: $JAVA_OPTS"
echo ""
echo "========================================================================= JAVA_OPTS="-javaagent:/home/mapp/glowroot-agent/glowroot.jar -Xms1303m -Xmx1303m ..."
"
echo ""

Hi Trask,

could you please let me know the exact line number or value, where i can put this assignment. they will not allow us to restart again.

appreciate your help here.

Regards, Vijay.

[trask]

I just noticed, it looks like you explicitly included the ellipsis from the wiki page:

JAVA_OPTS="-javaagent:/path/to/glowroot/glowroot.jar -Xms1303m -Xmx1303m ..."

This is meant to be a placeholder for the existing values.

Also, the wiki page notes to make this change to standalone.conf, not to standalone.sh.

I recommend testing and getting this working locally before trying to push to a controlled environment where you are unable to perform additional restarts.

Hi Trask,

Thanks for the updates. sorry for interrupt you again but Just wanted to confirm on below points.

1. what will be the exact JAVA_OPTS assignment for java environment.
2. i will update the same in standalone.conf file but do we need to change anything else apart from this
3. i have updated the glowroot parameters file with the application details.
4. Is there any compatibility metrics for java applications.

Thanks & Regards, Vijay.

[trask]

1. All you need to do is add -javaagent:path/to/glowroot.jar to your JAVA_OPTS
2. Nothing else
3. I'm unsure which file you are taking about?
4. Java 6+

[vijayninave]

Hi Task,

If this is supported for Java 6+ , please let us know which components are compatible for eg. Jboss, weblogic, tomcat etc.?
