This article describes how to get started with AWS CloudWatch metrics integration for Opvizor/Cloud

Overall Metrics Flow

Steps

Setup Telegraf service with the provided telegraf.conf configuration from Opvizor/Cloud Integrations page.

Make sure to adjust the access_key for secure authentication from AWS Firehose.

Telegraf can be retrieved and installed with the following command lines

wget https://dl.influxdata.com/telegraf/releases/telegraf_1.26.3-1_amd64.deb sudo dpkg -i telegraf_1.26.3-1_amd64.deb_amd64.deb
sudo cp ./telegraf.conf /etc/telegraf/telegraf.conf
sudo systemctl enable telegraf
sudo systemctl restart telegraf 

Watch our screen capture to ease your setup.

Note that AWS Kinesis Firehose data stream requires secure endpoint as destination therefore a valid TLS certificate must be set for the telegraf service.

Additionally it is not possible to point the AWS Kinesis Firehose to send metrics to a destination endpoint with port other than 443. To overcome this you can setup a port-forwarding using for example socat and enable it as a system service
