OneAgent SDK for Python oneagent.initialize fails

npg — Mon, 07 Jun 2021 10:37:33 GMT

I encounter an error calling OneAgent SDK for Python oneagent.initialize within a docker container and I'm getting

InitResult(status=-1, error=SDKError(-1342308345, 'onesdk_initialize_2: Could not load agent.'))

that does not correspond to any of the errors listed at

https://dynatrace.github.io/OneAgent-SDK-for-Python/docs/sdkref.html#oneagent.common.ErrorCode

I'm using oneagent-sdk==1.3.0.20191113.161138 and I've installed the latest dynatrace-install.sh from api/v1/deployment/installer/agent/unix/paas-sh

Other printouts during the initialization

I see that liboneagentloader.so does exist at /opt/dynatrace/oneagent/agent/lib64/ even though it reports that

[onesdk] Could not load agent module for Dynatrace OneAgent SDK for C/C++: liboneagentloader.so: cannot open shared object file: No such file or directory

What else should I check?

Thank you

Hello, there are some things you could check here:

https://github.com/Dynatrace/OneAgent-SDK-for-Python#troubleshooting

The main issues you could have are using a musl image (like alpine) or installing the oneagent-sdk lib for a different architecture. Do you have more details about how your Dockerfile looks like and how have you installed the oneagent-sdk pip package?

Issue resolved -- docker image was missing the step

export LD_PRELOAD=/opt/dynatrace/oneagent/agent/lib64/liboneagentproc.so
