Hector bd841c3a35 feat: set up metric to 0 if errors found
The `up` metric is now based on whether an error was found while reading
data from the database to build other metrics. Note that there is a chance
the `up` metric will not be correctly set if the last metric to be built
before the `up` metric does not throw an error.
