Performance Testing Metrics

Hello All,

I need help to know how to get below things in Postgresql :-
1) No. of active connections?
2) No. of non-responding connections?
3) Queries which are running beyond time(i.e. time which 'll set in database
query)?
5) Dead Locked Queries?
4) Process ID's of dead-locked queries?
5) No. of queries in non-responding state?

Can be selected from pg_stat_activity. The exact query depends on
PostgreSQL version and on what you consider "active" to mean.

How will you set that? What is the difference from "non-responding
connections"?

Deadlocks are automatically resolved and logged. Check the log.

How is that different from "non-responding connections" in 2?

You might want to check on the tools mentioned on this page:

http://wiki.postgresql.org/wiki/Monitoring

If points 2, 3, and the second point 5 are about blocking, you might
be interested in these pages:
