I might be completely crazy here, but it seems every other database
exposes select query stats. Postgres only exposes updates/deletes/
inserts. Is there something I am missing here?

Perhaps.
You can EXPLAIN ANALYZE a SELECT, just like i/u/d -- but then you
don't get
What I am looking for is that our DB is doing X selects a min.
Turning on logging isn't an option as it will create too much IO in
our enviornment.

What specifically would you like to measure?
Duration for specific queries?
Queries in an app for which you have no source?
There may be a way to get what you want by other means ...
Details?
I gather you cannot
In any other DB (oracle, mysql) I know how many queries (selects) per second the database is executing. How do I get this number out of postgres?I have a perl script that can test this, but no way the db tells me how fast it's going.(e.g. in oracle: select sum(executions) from

You can't. You also can't know how many DML statements were executed

Yeah, I'm not really concerned about the app or sys performance, just
a basic question of how do I get the rate of selects that are being
executed.
In a previous post from Jim, he noted it cannot be done. I am very
surprised postgres can't do this basic functionality. Does anyone
know if

If you're using 7.4, you can use log_duration to only log duration. It
won't log all the query text, only one short line per query. Then you
can use pgFouine to analyze this and

So, Dan, the question is, what are you trying to measure?
This might be a statistic that management has always been given,
for Oracle, and you need to produce the same number for PostgreSQL.
If not, it's hard to figure out what a
15 matches
