If you've ever used Prometheus, you know it's pretty great. It's free, open-source software that uses metric-based monitoring and allows users to set up real-time alerts. Prometheus generates tons of system data, and this data can be pulled from Prometheus through various methods.
Using Prometheus's REST API, it's easy to look at historical data and see trends. Simply choose a time range and at what time intervals to pull the data, then analyze the data and generate metrics, such as maximum values and averages over that period.
But what if you wanted to ingest real-time data from Prometheus, and analyze and make decisions based on this data in real-time? That's where Deephaven comes in!
