Documentation is not clear on comparison between Prometheus Pushgateway and aggregation-gateway

[cmg1986]

Hello,

I am using already Prometheus Pushgateway which is not able to aggregate metrics and cant drop even by itself after getting scraped.

When we say for aggregation-gateway, then does it have all feature like Pushgateway with Aggregation OR it supports only aggregation.

Do i need to use both in combination OR aggregation-gateway is only enough ?

First get metrics in aggregation-gateway to run aggregation -> Then aggregation gateway pushes those aggregated metrices to Push Gateway -> Then Prometheus scrapes metrics from /metrics endpoint of Pushgateway.
