Take a look at the public dashboard that visualizes the current user count on my Redash instance!
The server runs on a t2.micro instance, backed by the Redash Ubuntu AMI.
I am using Amazon SES as the mail service.
To visualize something in Redash, you need a query.
And you execute a query on some data.
Fortunately, Redash has a default dataset (itself!) to play with, instead of hooking up an external data source.
Create a new Query (/queries/new):
Let's aggregate events by action and type of a Redash instance:
SELECT count(*) as times , action , object_type FROM events group by action, object_type order by times desc
Use the following configuration to create a visualization:
You should end up with something like this:
It seems like a nice piece of software, my idea is to integrate Redash with mnesia to visualize things you saved in mnesia!
