I'm not sure if this is a bug. It's very probable that I did something wrong.

The metric is the number of requests to nginx. The number of requests is very low. The frequents "bumps" are requests made by nagios (once per 5 minutes I think).

I asked on IRC first and someone said that I should get zeros if all my values are the same.

Can you show us the result in the "Console" view of the expression browser?

That's not zero, this is a UI problem.

I was thinking it was zeros because of the grafana graph :

It's probably worth filing a bug against grafana for better selection of min/max.

You can set the min in the graph options.
