The graph link is broken because its query is too long and gets truncated. This is because the query uses a hardcoded list of possible servers to be able to set a default tick rate of zero with JoinWithLiteralTable(). Unfortunately, you need to specify exactly what streams you are joining with to be able to use JoinWithLiteralTable, so we have to hardcode which servers we're interested in.

We could fix the graph link by manually overriding the alert template when registering the alert.
