how to run multiple machine agent for multiple jvm (more than one microservices) running on one VM.

[ankjain]

Is it error if i wont run multiple machine agent for my multiple java microservices which are running on same machine ?

If answer is yes i.e multiple machine agent to be configured for each appagent running on machine then why it is required to copy separate machineagent directory for each instance of machine agent per appagent pair. 

i am running three java services on one machine say linuxvm 

linuxvm --> myapp1 (java parameter passed to appagent )

-Dappdynamics.agent.tierName=myapp1 -Dappdynamics.agent.uniqueHostId=myapp1 -Dappdynamics.agent.nodeName=linuxvm-myapp1

linuxvm--> myapp2

-Dappdynamics.agent.tierName=myapp2 -Dappdynamics.agent.uniqueHostId=myapp2 -Dappdynamics.agent.nodeName=linuxvm-myapp2

linuxvm --> myapp3

-Dappdynamics.agent.tierName=myapp3 -Dappdynamics.agent.uniqueHostId=myapp3 -Dappdynamics.agent.nodeName=linuxvm-myapp3

Question is if 3 machine agent needs to be run for each appagent on same machine then do i have to configure tiername and nodename parameter again in machineagent controller.xml config file  or just put uniquehostid parameter ?

@ankjain did you find an answer you can share for this question in the community, how did it go? Or are you still in need of assistance?

You can try to use only 1 machine agent package however run 3 different machine agent process to pair and associate with your 3 JVms each of which is pointing to different Tier.

In the machine agent config DON'T specify app name, tier or node name.  Just start 3 different machine agent process by just passing uniqueHostId only. This way each machine agent process should pair and associate with each JVMs reporting in different tiers.  Let me know how it goes.

Something like below

nohup <path_to_java>/bin/java -Dappdynamics.agent.uniqueHostId=myapp1 -jar <path_to_machineagent>/machineagent/machineagent.jar &

nohup <path_to_java>/bin/java -Dappdynamics.agent.uniqueHostId=myapp2 -jar <path_to_machineagent>/machineagent/machineagent.jar &

nohup <path_to_java>/bin/java -Dappdynamics.agent.uniqueHostId=myapp3 -jar <path_to_machineagent>/machineagent/machineagent.jar &
