Hello!
Thanks for your answer. 
I don't think use Canvas could be possible, because I need this data in a dashboard and Canvas is not " embeddable in dashboards (yet)".
I will try to use the Uptime app and see if it works.
In other hand, If I have this visualization:
Can I get the interval of this metrics when it goes to 0 and make it a table? (Is for the same propouse than I describe upside)
:cheers:
