Step 1: Create Monitoring User
We recommend creating a separate monitoring user on your PostgreSQL database for pganalyze.
Connect to your database with cloudsqlsuperuser privileges (i.e. the initial user that was created on instance creation), e.g. using
Run the following SQL commands to enable the
pg_stat_statements extension, and make sure it was installed correctly:
CREATE EXTENSION IF NOT EXISTS pg_stat_statements; SELECT * FROM pg_stat_statements LIMIT 1;
Connect to the database you will be monitoring, again as a user with cloudsqlsuperuser privileges. Then run the following to create a monitoring user (we've generated a random password for you, but you can replace it with one of your choosing):
CREATE USER pganalyze WITH PASSWORD '[could not generate password]' CONNECTION LIMIT 5; GRANT pg_monitor TO pganalyze; CREATE SCHEMA pganalyze; GRANT USAGE ON SCHEMA pganalyze TO pganalyze; GRANT USAGE ON SCHEMA public TO pganalyze; CREATE OR REPLACE FUNCTION pganalyze.get_stat_replication() RETURNS SETOF pg_stat_replication AS $$ /* pganalyze-collector */ SELECT * FROM pg_catalog.pg_stat_replication; $$ LANGUAGE sql VOLATILE SECURITY DEFINER;
Note that it is important you run these as a user with cloudsqlsuperuser privileges in order to pass down the full access to statistics tables.
Let's make sure we can connect to the database with the new user:
PGPASSWORD=[could not generate password] psql -h 220.127.116.11 -d mydatabase -U pganalyze
Write down the username and password of the monitoring user, we will use it in the last step of this tutorial.
Next we continue by installing the pganalyze collector:Proceed to Step 2: Install the collector
