Обсуждение: Report Generator Proposal
Hi all, each time that someone say: this query is slow, this query take forever, bla bla bla all our request are: 1) Which version are you running ? 2) May I see your table definition? 3) May I see you configuration file? 4) May I see the explain ? 5) ....... sometimes a beginner is scared about all these questions and even he/she don't know how do collect these informations and we lose important data about: "why that damn query is too slow"? may be is usefull generate an automatic report that take charge of collect all these informations and send it to a file or directly to pgsql-performance@postgresql.org , may be something like: > BEGIN REPORT TO FILE <file_name> > SELECT ...... > END REPORT; or > BEGIN REPORT TO EMAIL <address> > SELECT ...... > END REPORT; Regards Gaetano Mendola
Nobody entusiastic ? I'm wrong about my feeling ? I think that have the psql able to generate a report will increase the our better response to a user novice or not ?

I rather like it actually. Cisco equipment has a 'show tech-support' command that does exactly that, dumps all the config,HW/SW versions, current state, you name it. If you have a problem you run that, attach the output to yr support email, and 99%of the time there's enough info there to solve the problem. It'd be easy to automate all except the explain, a script that did everything else could then emit "If your preoblem relatesto a specific query, then run 'explain analyze <query>' and attach it to your message as well". > -----Original Message----- > From: pgsql-admin-owner@postgresql.org > [mailto:pgsql-admin-owner@postgresql.org]On Behalf Of Gaetano Mendola > Sent: 15 September 2003 16:25 > To: pgsql-admin@postgresql.org > Subject: Re: [ADMIN] Report Generator Proposal > > > Must I suppose that the idea rejected ? > > ----- Original Message ----- > From: ""Gaetano Mendola"" <mendola@bigfoot.com> > Newsgroups: comp.databases.postgresql.admin > Sent: Thursday, September 11, 2003 11:52 PM > Subject: Re: Report Generator Proposal > > > > Nobody entusiastic ?

Well, must be charge of psql store somewhere all selects performed between the BEGIN REPORT and END REPORT and perform the explain command of that selects with the explain; may be the really difficult here is that psql shall know all tables involved in a select and insert in the report the descriptions of that tables. Before to work on it I want be sure that is a good idea.

((wheat from chaff and all that)) hmm. though there's still the (some small percentage of) things that could be going wrong with custom stored procedures. dumping those would be (I'm presuming, based on the scope of the task as it's been described) reasonably simply, but figuring out what they touch could be prohibitive? kudos for any attempt, though, all around. :) -kaolin fire -postgresql novice -http://poemranker.com

TIP 9: the planner will ignore your desire to choose an index scan if your
joining column's datatypes do not match
Oracle have something similar: RDA which generates HTML reports for the hardware, SO, and database.
It doesn't do explains but does show which SQLs are the most expensive, etc.
It could be worth having a look at that for ideas on what and how to report it.

I was thinking to generate the report with the psql, not with an external
program, somethink like this:
Welcome to psql 7.X, the PostgreSQL interactive terminal.
Type: \copyright for distribution terms
\h for help with SQL commands
\? for help on internal slash commands
\g or terminate with semicolon to execute query
\q to quit
test=# BEGIN REPORT TO my_report_file;
BEGIN REPORT;
test=# select * from ........
[SNIPPED RESULT]
test=# END REPORT;
END REPORT;
