Another Option for Monitoring the 'up' Metric in Grafana Agent

[michaelact]

I'm currently exploring Grafana Agent (push-based), and one limitations I've come across is that if the agent fails to remote write / send metrics, the up metric won't be displayed.

In Prometheus and use a pull-based approach, Prometheus will show the up metric as 0 instead of an empty metric.

Do you have any other approach?
