Prometheus Cheat Sheet - Basics (Metrics, Labels, Time Series, Scraping)
Here we focus on the most basic Prometheus concepts - metrics, labels, scrapes, and time series.
What is a metric?
In Prometheus, everything revolves around metrics. A metric is a feature (i.e., a characteristic) of a system that is being measured. Typical examples of metrics are:
- http_requests_total
- http_request_size_bytes
- system_memory_used_bytes
- node_network_receive_bytes_total
