With the help of sidecar pattern, the Telegraf agent with appropriate Application input plugins (https://github.com/influxdata/telegraf#input-plugins) is enabled and deployed in the same pod where the application is hosted. Also, you can use or modify the telegraf agent installed in each node for collecting node metrics to monitor the applications deployed in Kubernetes with the appropriate input plugins configuration. All these metrics must have the proper pod name or pod id so that VMware Aria Operations parses the metrics and displays them in the VMware Aria Operations user interface.
Sample sidecar deployment configuration of telegraf agent to monitor Redis is provided in Redis Telegraf Input Plugin.
