Issue/Introduction

Is it possible to build simple container holding DX-APM .NET Core agent on top of 3rd party supplied application container without using UMA? 

Environment

• DX APM SAAS
• DX APM 2X

Resolution

Manually include the following in your App Dockerfile:

 

# Add agent
ENV CORECLR_ENABLE_PROFILING=1 \
     CORECLR_PROFILER={5F048FC6-251C-4684-8CCA-76047B02AC98} \
         CORECLR_PROFILER_PATH_64=/home/agent/wily/bin/wily.NativeProfiler.so \
             com.wily.introscope.AgentProfile=/home/agent/wily/IntroscopeAgent.profile \
                 agentManager.url.1=localhost:5001

 

NOTES: 

The above one assumes that the .NET agent is copied into the container image at /home/agent/wily

Change the agentManager.url.1

Change the agentManager.credential as well if needed.

 

 

EXAMPLE:

FROM aspnetapparnw:6.0
 
RUN mkdir -p /home/agent/wily
ADD DotNET_Linux_2023.6.1.5.tar.gz /home/agent/wily
 
ENV CORECLR_ENABLE_PROFILING=1 \
    CORECLR_PROFILER={5F048FC6-251C-4684-8CCA-76047B02AC98} \
    CA_APM_MONITORING_ENABLED=true \
    CORECLR_PROFILER_PATH_64=/home/agent/wily/dotnetagent/bin/wily.NativeProfiler.so \
    com.wily.introscope.AgentProfile=/home/agent/wily/dotnetagent/IntroscopeAgent.profile \
    agentManager.url.1=wss://<YOUR-apm-endpooint>:443 \
    agentManager.credential=<YOUR-credentials> \
    introscope.agent.hostName=<MYLAB> \
    introscope.agent.customProcessName=<XXX> \
    introscope.agent.agentName=DotNETAPP
