Which of the following tools is specifically identified for infra monitoring for VMs or EC2s?

The selected answer effectively identifies Graphite as a tool used for infrastructure monitoring, particularly for virtual machines (VMs) and Amazon EC2 instances. Graphite is a robust monitoring tool designed to collect and visualize time-series data, making it suitable for monitoring the performance of servers and applications. It primarily operates by receiving metrics from various sources and storing them for later retrieval and visualization, which is essential when managing infrastructure.

Graphite's architecture allows it to handle vast amounts of data points efficiently, which is crucial when monitoring the operational aspects of cloud instances like VMs or EC2s. Its ability to provide comprehensive visualizations, including dashboards, enables teams to easily track the performance and health of their virtualized environments in real-time.

The other tools mentioned, while useful in their own contexts, do not have this specific identification for infrastructure monitoring in the same manner. Grafana is primarily a visualization tool that works with various data sources, including Graphite, but isn't utilized specifically for the monitoring itself. Prometheus is more focused on time-series data collection and monitoring, but again, its primary use is not solely for VMs or EC2s, and it is often considered for containerized and microservices environments. Graphite is recognized for its strong capability in
