Hello
Does psql maintain some sort of global performance counters?
We are interested mainly in following counters (cumulative, by all psql processes):
- cpu time by all backends
- sql queries count
- fsync count
- disk reads / disk bytes read
- disk writes / disk bytes written
- transaction commit count
- client connect count
- client disconnect count
- backend start count
- backend terminate count
We intend to use these counters (their differences for fixed time periods) for monitoring and reporting purposes.
Thanks,
Cestmir Hybl
