I have tried to setup for one java application by imorting into system prop. while starting getting below error.

Startup file config:

===========
#!/bin/sh
cd $(dirname $0)
export JAVA_HOME=/usr/java/jdk1.8.0_91
export JAVA_OPTS="$JAVA_OPTS -Xmx2048m"
export JAVA_OPTS="$JAVA_OPTS -Dprop.appconfig.path=../conf/appconfig.properties"
export CLASSPATH=../lib/*:.

exec /usr/java/jdk1.8.0_91/bin/java $JAVA_OPTS -Dcomponent=QueueMsg -cp $CLASSPATH QueueMSG "Instance1"

Getting below errors:

Any one can help on this to setup agents and dashboard for my applications.

It seems like you have the line exec /usr/java/jdk1.8.0_91/bin/java $JAVA_OPTS twice in your startup script. Maybe that's the cause of the error?

Note that the Java agent requires at least APM Server version 6.5.0. For more info check out the docs: Introduction | APM Java Agent Reference [1.x] | Elastic

Dear Felixbarny,

Thanks for your feedback.

if i run with single java also am getting the same issue. PFB logs.

felixbarny · April 10, 2019, 9:16am

This is actually a different error now. It indicates that setting the config has worked now. But you need to use APM Server 6.5.0 or newer with the Java agent.

Sajid_Md · April 10, 2019, 1:45pm

Hi Felixbarny,

now i have updated APM server to 6.5.0. but while starting apm servers its throwing error for Kibana port.

im running kibana on 9369
ES on 9200
APM server configure with 9210

can you please let me know why apm-server is truing to deploy on Kibana port. ?

I'm glad you were able to get apm-server updated. Can you double check your configuration (or share it here)? Based on the information provided, I would expect it to include:

apm-server:
  host: "0.0.0.0:9210"

but suspect it's set to 9369 currently.

Sajid_Md · April 11, 2019, 2:21am

Hi Gil,

Thanks for your response. PFB details.

Kibana Service Status and It's port:

Elastic search Service status and its port:

Here is the apm-server config file:

am not able to paste complete file here. Attached link here for apm-server.yml

https://wetransfer.com/downloads/c8d2b970e12976e8307bd2314b3306c920190411022038/a8414e822fb05a618abf5a6f356db9bd20190411022038/2d8498

gil · April 11, 2019, 12:23pm

@Sajid_Md Thanks for providing that information. The [tricky] problem is that in the apm-server.yml provided, the host is set like this:

apm-server:
  host: "10.176.11.39:9210"
# tons of comments ....
  host: "10.176.11.39:9369"

setup.kibana:
  host: "10.176.11.39:9369"

The last setting for apm-server.host wins - Remove that middle host entry and you should be all set.

Sajid_Md · April 12, 2019, 6:47am

HI @gil .

Thanks for the update. Now it's working fine. the agent has been up and running now.

But In Kibana dashboard APM tab was not added, it's showing in dashboard list like below. How to add APM as a separate tab in Kibana dashboard.

Also I have few quesions:

Which type of data will be pushing into APM server from agent applications.
For example, I added an agent for one application that will take the input from one application and insert into DB servers. here which type of logs I can expect into APM server?
In the APM dashboard, I can see a total of 5 tabs for APM in that Span details is not showing for my applications.
Error details and Error dashboard tabs will show when we are having errors from applications?
How to add the main APM tab in my Kibana dashboard like below.

Could you please help me resolve my concerns.

Thanks in advance...

Sajid_Md · April 13, 2019, 7:20am
