Building a real-time monitoring system for metrics of servers in Rust.
Here is an example of how you could write code in Rust to collect and send metrics to a storage tool such as Prometheus:
This example collects the number of processes running on the system using the sysinfo library and stores the metric in a Prometheus counter. The counter is then registered with a registry and the metrics are printed in Prometheus format using the gather() method.
To send the metrics to a storage tool, you can use the HTTP API provided by the tool to send the metrics over HTTP. For example, to send the metrics to Prometheus, you can use the prometheus_pushgateway crate to send the metrics to the Pushgateway, which is an intermediary service that allows you to send metrics from ephemeral and batch jobs to Prometheus.
