1 . The tooltip takes some time to show up, whereas the tooltip on other
elements like the title elements under Topology summary shows up immediately. I
played around a bit and found a way to show the tooltip on disabled button
immediately using the same style as other tooltips. You need to wrap the input
element in a span like below,
```javascript
<span style="display:inline-block;" data-toggle="tooltip" title=""
data-original-title="To debug set topology.eventlogger.executors to a value > 0
or nil">
<input disabled="" onclick="confirmAction('test-topology-1-1459402415',
'test-topology', 'debug/enable', true, 10, 'sampling percentage', 'debug')"
type="button" value="Debug" class="btn btn-default">
</span>
```
2 . The tooltip is shown even if the button is enabled. You could add the
`<span> </span>` only when number of executors is 0, which would take care of
this.
3 . The tooltip is also shown when the debug button gets disabled after the
user clicks on it (when topology.eventlogger.executors > 0). Similar fix as
above.
4 . The button should be disabled in the spout/bolt pages as well.
