Обсуждение: Help with process list

Hello, I have a couple of bussy pgsql 8 servers running in my office, in
MySQL I use SHOW PROCESSLIST to show the actual process running in the
MySQL server (idle time, resources and other statistical data) and a
little perl app named mytop to show the data like the top unix
utility... There such way to do the same or similar stuff in PostgreSQL?

Thanks a lot...

Hello,

you can use

intra=# SELECT * from pg_stat_activity ;
 datid | datname | procpid | usesysid | usename | current_query |
query_start
-------+---------+---------+----------+---------+---------------+-------------------------------

PostgreSQL can log long time executed sql commands. Set
log_min_duration_statement on some value in your postgresql.conf file.
I have good experience with it. Its very usefull for finding long sql
cmds.
