Datascope
Visability into your Postgres 9.2 database via pg_stat_statements and cubism and using the json datatype.
Check out a live example
Heroku Deploy
Datascope needs two Postgres 9.2 databases. The first is a DATABASE_URL with the datascope schema, the second is a TARGET_DB with the pg_stat_statements extension.
$ heroku create
$ heroku addons:add heroku-postgresql:dev --version=9.2
Attached as HEROKU_POSTGRESQL_COPPER_URL
$ heroku config:add DATABASE_URL=$(heroku config:get HEROKU_POSTGRESQL_COPPER_URL)
$ heroku pg:psql COPPER
=> \i schema.sql
CREATE TABLE
$ heroku addons:add heroku-postgresql:dev --version=9.2
Attached as HEROKU_POSTGRESQL_GREEN_URL
$ heroku config:add TARGET_DB=$(heroku config:get HEROKU_POSTGRESQL_GREEN_URL)
$ heroku pg:psql GREEN
=> create extension pg_stat_statements;
CREATE EXTENSION
$ git push heroku master
$ heroku scale worker=1
Basic Auth
If you don't want your deployment of datascope to be publicly visible, simply add environment variables for BASIC_AUTH_USER and BASIC_AUTH_PASSWORD.
heroku config:add BASIC_AUTH_USER=admin BASIC_AUTH_PASSWORD=password
