> Federation endpoint is just another scrapping target - in case of network failure (or any other failure) I will get an alert that federation endpoint is down
This is true. However the flip side is that remote_write buffers metrics while the network is down, whereas federation will not back-fill any historical data when the network comes back up. You can alert on a remote_write endpoint going away, as described here: https://groups.google.com/g/prometheus-users/c/ur9Tu1kRu6w/m/Q81qPxqQAAAJ I think you can make a generic alert against loss of *any* remote write sender - something like this (untested): *up{prometheus_agent="true"} offset 1h unless up* (i.e. "alert if the given metric/timeseries was present one hour ago but isn't present now") -- You received this message because you are subscribed to the Google Groups "Prometheus Users" group.
