PostgreSQL: non-GUI monitoring

I've read a lot about PostgreSQL monitoring through GUI tools but that doesn't match our modus operandi: shell or Perl scripts tied to SCCS for change-control/auditing, run via cron or interactively. We tend to prefer the command line over point-and-click.

The closest I've found is pg_top, which I'm working on installing (grumble grumble), and check_postgres.pl, which is a back-end to data collection for Nagios and MRTG. Although the graph presentation is pretty, it's no开发者_如何学Pythont our approach... but the Perl itself appears quite useful (so far).

Are there other non-GUI tools out there I may be missing? Although I could write what's needed, I'd hate to reinvent wheels.

Thanks.

Did you have a look at the built-in monitoring views?

There is also pgStatspack for performance monitoring:
