Metrics are a way to measure things.

For instance, in networks, it is used to identify the cost of an operation. If you have a packet that needs to go from router A to router B, it can get there by either going through router D or router C. Router A will calculate the cost, this is based on metrics. A router can calculate a metric by looking at what routing protocol is used by another router and its bandwidth. It will try to always use the router with the lowest metric.
