I am a bit confused by the result I am seeing from ‘min’ or ‘min_over_time’
For example I have metric ‘up’ for the status of an exporter target.
up{instance="target"}
The result is '0'
This is expected, the target is down.
Next is where it goes wrong…
min_over_time(up{instance="target"}[1h])
the result is '1'
I also tried
min(up{instance="target"})
but this also comes back as '1'
Where is it getting ‘1’ from, especially as a minimum?
