Module hotshot_types::traits::metrics

The Metrics trait is used to collect information from multiple components in the entire system.

This trait can be used to spawn the following traits:

• Counter: an ever-increasing value (example usage: total bytes send/received)
• Gauge: a value that store the latest value, and can go up and down (example usage: amount of users logged in)
• Histogram: stores multiple float values based for a graph (example usage: CPU %)
• text: stores a constant string in the collected metrics
