Extending panels with statistics (e.g. SqlAlchemy)

[jvanasco]

I found it useful to extend the SqlAlchemy panel with this quick template fix to show some high-level statistics:

% if queries:
	<%
		durations = sorted([query['duration'] for query in queries])
		d_total = sum(durations)
	%>
	<p>
		Total: <span class="label label-default">${d_total} ms</span>.
		Min: <span class="label label-default">${durations[0]} ms</span>.
		Max: <span class="label label-default">${durations[-1]} ms</span>.
	</p>
	<hr/>
% endif

Between that and the "sticky panel" feature, I've been able to track down a lot of bottlenecks during development pretty well.

Is anyone else using similar stats / have suggestions?

I am thinking about a PR that includes this data, but computed within Python (so other panels could potentially share information. The general idea is that I'd like to eventually have a Single panel that uses Chart.js (or similar) to visually display workloads processed by multiple panels (e.g. SqlAlchemy + Dogpile ).
