Charting trends

[Kevin Kempter]

Hi List;

In my last gig (a postgres shop) we used MRTG to run a number of queries that 
every 5 minutes tracked things like overall db size, table sizes, number of 
sequential scans vs. number of index scans, etc. With MRTG we were able to 
create a set of daily, monthly and YTD graphs that showed at a glance the 
growth or trends of these items.

2 questions:

1) I'm a total newbie when it comes to nagios, can I do the same thing with 
nagios and the postgres plugin ? 

2) if I manage to run a set of queries outside of nagios can I use nagios to 
simply graph the data ?

Thanks in advance...
