Run ADOTCollector Beta on Debian and Ubuntu

To run ADOTCollector on Debian (or Ubuntu) EC2 host, you can choose to install ADOTCollector on your host by the following steps.

Steps,

wget https://aws-otel-collector.s3.amazonaws.com/ubuntu/amd64/latest/aws-otel-collector.deb

(Optional) Verify the package integrity.

wget https://aws-otel-collector.s3.amazonaws.com/aws-otel-collector.gpg
gpg --import aws-otel-collector.gpg
sudo apt install dpkg-sig
dpkg-sig --verify aws-otel-collector.deb

If the package is verified, you should see output similar to this:

GOODSIG _gpgorigin XXXXX...

However, if you see BADSIG or UNKNOWNSIG, you should stop and try download the deb package from the offical source again.

Install aws-otel-collector DEB by the following command on the host

sudo dpkg -i -E ./aws-otel-collector.deb

Once DEB is installed, it will create ADOTCollector in directory /opt/aws/aws-otel-collector/
We provided a control script to manage ADOTCollector. Customer can use it to Start, Stop and Check Status of ADOTCollector.
- Start ADOTCollector with CTL script. The config.yaml is optional, if it is not provided the default config will be applied.
