I am trying to enable monitoring on a Task running Node.js on AWS Fargate - the base image is node. I followed the steps outlined in Install OneAgent, no errors found at the time of build and after running the task, I could see in the logs that it prints the following:
Info: Using DT_HOME: /opt/dynatrace/oneagent
I don't see any other Dynatrace specific error on INFO messages. The ECS Fargate is not listed in my Dashboard.
I am also sharing the content of Dockerfile below, could I get help on what is missing or what I didn't follow in the instructions?
RUN mkdir -p "$DT_HOME" && \
wget -O "$DT_HOME/oneagent.zip" "$DT_API_URL/v1/deployment/installer/agent/unix/paas/latest?Api-Token=$DT_API_TOKEN&$DT_ONEAGENT_OPTIONS" && \
unzip -d "$DT_HOME" "$DT_HOME/oneagent.zip" && \
COPY . /server
RUN npm install
ENTRYPOINT [ "/opt/dynatrace/oneagent/dynatrace-agent64.sh" ]
CMD ["npm", "start"]
Are you running the container alone or the task also deploys any other security container? ( As I have seen in the past some solutions that conflicted with Dynatrace OneAgent)
The message you see "Info: Using DT_HOME: /opt/dynatrace/oneagent " comes from the execution of "/opt/dynatrace/oneagent/dynatrace-agent64.sh"
By default Dynatrace oneAgent does not print information into cloudwatch as it can be too chatty, but you can enable that for NGINX with the environment variable DT_NGINX_OPTIONS=loglevelconinfo.
With that option enabled you will see the Dynatrace OneAgent logs in CloudWatch .
Are you using build/auto/runtime injection ? https://www.dynatrace.com/support/help/setup-and-configuration/setup-on-cloud-platforms/amazon-web-s...
Verify if you are using alpine linux or not
(if alpine, the oneagent image name will be : /linux/oneagent-codemodules-musl:<technology> )
Check the cloudwatch logs any reference to oneAgent or add the environment variable "DT_LOGLEVELCON=info" to get more details.
If still not seeing any information, try to run the image locally and you can ssh into the container and verify if the oneagent is running inside of the container.
Some related errors I have seen in the past is that the Dynatrace cluster or the repo where the oneagent image is, does not has a valid certificate, so docker will fail when pulling the image.
