Sequel support
Maybe we can examine queries executed by Sequel? RackMini supports Sequel and easily handle it. Maybe you can see the source code and adapt to ScoutApp?
After I GoLive, In production, I would like and love to see how much costs on Sequel operations by using Scout. Otherwise, I just not gonna see it and do not know how much time spent or which query is slow by looking to, ehrm, nothing.
Rather than "Sequel" or "ActiveRecord", why not just instrument the underling SQL libraries? Then it will work with everything.
Doesn't it use the pg, mysql2 or related gem for actually sending queries to the database?
I guess the challenge is if we instrument the raw query, you might have trouble putting it back in the context of the higher level operation, e.g. joins, transactions, includes, etc.
I agree. However, At least a basic support for Sequel should be in. Currently, the only reason I do not use DevTrace is that I cannot see how long it takes my queries. RackMini, S**light and Peek can see my queries ans show it to me. If they can do, Why not Scout?
Especially giving credit to DevTrace being an awesome development tool both as a profiling and UI. I personally hate RackMini because it is so ugly.
At least, Instrumenting RAW Queries is a start.
Perhaps we could use Skylight's sequel probe as a jumping off point?
Edit: Link removed to protect developers from weird license restrictions.
I will be looking at Sequel support soon though, I think basic instrumentation shouldn't be too hard.
I've started looking at Sequel, but haven't formalized it into a proper instrument yet. I'll see if I can find time this week to get it released.
@cschneid Thank you! I will be very happy to test your branch/PR and give feedback about it. Just ping me here if you need anything.
Really looking forward to this. As a bonus, ROM-RB also uses Sequel as its underlying databasing library, so that whole emerging ecosystem might also get supported automatically!
