prometheus-aws

The Terraform code will set up an EC2 instance and install Prometheus and Grafana using a userdata script.

Before running the Terraform code, you might want to change the following:

1. Add your IP address to the whitelist_ip in variables.tf, as the security group only allows access from the whitelisted IP.
2. Update the key_name for SSH in variables.tf.
3. Modify the PROMETHEUS_VERSION and CPU architecture in the userdata script to ensure you download the correct binary for your OS.

Once the installation is done, you can access the Prometheus dashboard on port 9090 and Grafana on port 3000.

If anything goes wrong, check the status to troubleshoot.

systemctl status prometheus grafana-server
systemctl status grafana-server.service
netstat -lntp

You can add or remove target config from the file /etc/prometheus/prometheus.yml.
