PostgreSQL Performance Monitoring Tools
https://github.com/CloudServer/postgresql-perf-tools
This package includes three useful scripts aimed to help to pinpoint performance issues on systems with PostgreSQL as database backend.
All scritps are written in Python. Requirements:
- Python 2.6+
- psycopg2 module (http://initd.org/psycopg/)
All scripts require a connect to PostgreSQL database. They take traditional set of DB credentials: host address, port (5432 by default), database name, database user and password.
Note: you may need to modify pg_hba.conf file to allow the scripts to connect to the server. Please refer to official documentaion:http://www.postgresql.org/docs/9.3/static/auth-pg-hba-conf.html
For detailed list of command line options use --help / -h option.
