Similar to top, - pg_top allows you to monitor PostgreSQL processes. It also allows you to: - - * View currently running SQL statement of a process. - * View query plan of a currently running SELECT statement. - * View locks held by a process. - - 2. Where do I get the latest version of pg_top? - - If you have git, you can checkout the latest at: - - git clone git://git.postgresql.org/git/pg_top.git - - 3. Is there a web page for pg_top? - - http://ptop.projects.postgresql.org/ - - 4. Is there a mailing list or on-line bulletin board for pg_top? - - Subscribe or browse the archives of ptop-hackers at: - - http://lists.pgfoundry.org/mailman/listinfo/ptop-hackers - - 5. What about Y2K/Year 2038 compliance? - - A full statement concerning top and the year 2000 can be found in the file - "Y2K" included with the distribution. - - 6. Will there be another major release of pg_top? Will there be a pg_top - version 4? - - We hope so! Depends on how much fun we have. :) - - 7. We just upgraded our operating system to a new version and pg_top broke. - What should we do? - - Recompile it. pg_top is very sensitive to changes in internal kernel - data structures. It is not uncommon for a new version of the - operating system to include changes to kernel data structures. - - - RUNNING - - 8. I just finished compiling top and it works fine for root, but when I - try to run it as a regular user it either complains about files it - can't open or it doesn't display all the information it should. Did I - do something wrong? - - Well, you're just not done. On many operating systems today, access - to many of the kernel memory devices and other system files is - restricted to either root or a particular group. The configure script - figures this out (usually) and makes sure that the "install" rule in - the Makefile will install top so that anyone can run it successfully. - However, you have to *install* it first. Do this with the command - "make install". - - 9. pg_top is (not) displaying idle processes and I don't (do) want it to. - - This default has only changed about a dozen times, and I finally got - tired of people whining about it. Go read the manual page for the - current version and pay special attention to the description of the - "PG_TOP" environment variable. - -10. The cpu state percentages are all wrong, indicating that my machine - is using 95% system time when it is clearly idle. What's wrong? - - This can happen if you compiled with gcc using the wrong include - files. See the previous question. - - - STILL STUCK - -11. I'm still stuck. To whom do I report problems with top? - - If after reading all of this file and checking everything you can you - are still stuck, then please refer to the mailing to ask further - questions: - - http://lists.pgfoundry.org/mailman/listinfo/ptop-hackers |
