The answer is "it depends". The network traffic caused by the scrsape and the CPU usage for sending and receiving the scrape payload itself obviously doubles. However, the storage requirement might not increase by much, because very similar or very regularly changing samples compress very well. On the other hand, it might increase by a lot (almost twice as much) if the metric values are more or less randomly changing. In practice, you simply have to try it out. You can use Prometheus to monitor how the Prometheus resource usage changes. :o) -- Björn Rabenstein [PGP-ID] 0x851C3DA17D748D03 [email] bjo...@rabenste.in -- You received this message because you are subscribed to the Google Groups "Prometheus Users" group.
