   There's some discussion around disadvantages of the push gateway in the Prom documentation. It's worth reading:
   https://prometheus.io/docs/practices/pushing/

   The two ones that stand out here to me are:

   1. By using a push gateway, you lose the health monitoring provided by the up metric (application-side metrics built by this lib will give you an automatic up=1|0 metric which you can use to monitor if the target/remote server is up or not; you don't get this with the push gateway)
   2. By using a push gateway, you introduce a single point of failure and potential bottleneck (your application needs to always be pushing data to a single instance of the push gateway, and if the push gateway fails or becomes overloaded, you will lose metrics)

   RE: "apparent advantage of the push gateway is the absence of a need for additional dependencies"

   Aren't you just trading one dependency, for another? You're trading a dependency on Redis, for a dependency on the PushGateway instead.

   Thank you for the very detailed answer. I also did some research and already changed my mind towards its better to use pull strategy.
