Re: Error in docker Extension

Hi @Hamed.khosravi

 

We are sorry that you are experiencing an issue with Docker visibility.

 

To investigate closely, we need to know the version numbers of the Machine Agent, Controller, and App Agent.

 

We also recommend referring to the Docker visibility documentation, in the meantime, and make sure that you have completed the configuration.

 

Hope it helps. Let us know how it goes.

 

 


Thanks,
Radhika P

Re: Error in docker Extension

hi, dears,

I'm using appdynamics controller 4.4.3 and version of machine agent
is 4.4.3.1214 and version of docker monitor is 1.0.32_2. it's very
important to me, i'm using docker on centOS7.5, in docker i deployed 5
tomcat8 with app server configured, I tested all tomcats and app
server working even custom metrics appears on controller, it's showing me
custom metrics about tiers, when i using machine agent without docker
extension, that's working but when i copy docker extension on monitors
directory in machine agent directory that's not working properly,
(cantharis, Spanish fly), all I got to explain to you is, I can browse in
my containers in the server tab on controller but machine agent by your
self doesn't show any data, when I remove the docker extension machine
agent send data to controller, I followed that instructions on
appdynamics doc and I did, please help me out to solve this issue.

Hi @Hamed.khosravi,

 

Have you properly validated your config file? Hope you are aware that YAML does not support tab.

We recommend validating your config file using some tools, such as YAML Lint

 

Let us know how it goes.


Thanks,
Radhika P
