Proxy fail with python agent

Christopher_Gil — Sun, 05 Apr 2020 12:30:23 GMT

Hi,

I'm new to Appdynamics and I'm having error messages coming up regarding the proxy when using a python agent, I would appreciate any help to resolve this issue.

If I follow the steps on the documentation and just create a /etc/appdynamics.cfg file :

[agent]

app = Test App

tier = Test Tier

node = node 0adb

[controller]

host = XXXX.saas.appdynamics.com

port = 443

ssl = (on)

account = XXX

accesskey = XXX

I get this error:

19:21:00,008 WARN [AD Thread-Metric Reporter0] MetricHandler - Metric Reporter Queue full. Dropping metrics.

If I edit the controller-info.xml in /usr/local/lib/python3.6/dist-packages/appdynamics_bindeps/proxy/conf/controller-info.xml

With:

<controller-host>EDITED.saas.appdynamics.com</controller-host>

<controller-port>443</controller-port>

<application-name>Test App</application-name>

<tier-name>Test Tier</tier-name>

<node-name>node 0adb</node-name>

<account-name>EDITED</account-name>

<account-access-key>EDITED</account-access-key>

<use-ssl-client-auth>true</use-ssl-client-auth>

Then I get these errors: (log file /tmp/appd/logs/proxyCore.2020_04_05__20_12_05.0.log )

Hi Christopher,

Could you please change

ssl = (on)

ssl = on

in the /etc/appdynamics.cfg file, restart your application as well as the JAVA proxy process and verify if that helps resolve the connectivity issues? Please also revert all the changes you did in the controller-info.xml file.

Best Regards,

Piyush
