As you can see in the screenshot above, I have two panels next to each other. When the third webservice from the top has a problem, it will show up (since I hide values with 0). If that happens, the table will become wider to allow for the entire URL to be visible. But this means it will make the next panel unreadable.
The reason I use a Graph and not a table, is so that it allows for alerting, since tables don’t support sending alerts, as far as I know.
