iostats per mysql process
Does anyone has any suggestions on how to get IO stats used by per process (mysqld) on Linux 2.6.18-53 kernel ... I just need to see how much reads and writes mysql is actually doing and what else is causing the IO load..

Re: MYSQL PROCESS
Can you give us the output of `uname -a` from your mysql hosts? There's a difference if you are running a 2.4 kernel vs. 2.6 kernel (Linux). In 2.4 kernel, try ps -ef, and in 2.6 kernel, ps -Lef. You may notice that PPID is the same for all PIDs except one, usually. -Paul On Thu, 2008-08-14 at 13:38 +0530, Krishna Chandra Prajapati wrote: But some of the mysql server(mysql server on debian) shows only one mysql process.

Re: mysql process 99.9 percent
Hi Most readers in this list expect OS and MySQL server information etc before responding. In our experience this is usually caused by poor SQL query construction e.g. large result set e.g. x million rows and/or index choice, database table design and/or MySQL server setup. Turn-on logging, rerun selected queries with and without the explain syntax, look at the MySQL administrator process list to see which query is the problem whilst the CPU is 99.9 %. Good news is : 'it is solvable'.

OK, would you mind providing the SQL query that's being executed when you click that hyperlink? You see, MySQL doesn't have anything to do with hyperlinks and searching (well, not searching at the user-level, anyway). It only knows about SQL queries. So if something's making it go slow, the culprit is an SQL query, not a hyperlink.

FWIW, we have at least one case where the server gets itself into a loop for no obvious reason. See http://bugs.mysql.com/bug.php?id=414 and http://bugs.mysql.com/bug.php?id=12061 for more details. If the problem at hand is related to this bug, I'd be very interested in hearing from you, especially if you can reproduce the problem easily. Note that the submitter of the second-mentioned bug report has done a very good job of describing his problem. Only reports of similar quality would be of much help. If this isn't your (Joeffrey's) problem, it might give you an idea of the kind of information we're looking for.

I use the same my.cnf, and show processlist show me more than 1 process on both machines. Both of these machines are slave DBs. The one that only has 1 process tends to lag behind a lot. I am not sure that they are somewhat connected. Any idea?

Re: MySQL process increasing problem..
Those are threads, not processes. Each connection gets a thread. Many connections waiting for disk space will give you this problem.

Because the MySQL database server process has nothing to do with the connections that are made to it. You are also probably running on Windows which does have 'interesting' file handling semantics, to say the least. You will need to stop the MySQL server before trying to delete the files. On the other hand, you would be better off to use the normal 'drop table' and 'drop database' commands from within MySQL, really. -Mark - Before posting, please check: http://www.mysql.com/manual.php (the manual) http://lists.mysql.com/ (the list archive) To request this thread, e-mail [EMAIL PROTECTED] To unsubscribe, e-mail [EMAIL PROTECTED] Trouble unsubscribing?

MySQL Process ID Unix PID
Hi, Is there a way to compare between a mysql process ID showed in top or ps with a process ID from mysqladmin processlist ? I'm asking this because we operate a mysql machine used for webhosting and it has many users and many databases. If users do crazy stuff that result in high usage of resources, we need to determine who is the user, which database is it accessing and finally what script causes the problem. Any ideas or utils/scripts for digging this info apreciated. Tnx.

Show Tables Freezing a MySQL process
Hi Everyone. Here's a VERY unusualy problem. We are running a mod_perl application with MySQL. One of the functions in the program performs a SHOW TABLE command. This is performed with apparently great regularity within the program. It has begun locking a process up, at 100% CPU (All held by system). When this occurs the process will respond to nothing. I try kill -9, I try the kill command via mysqladmin or mtop. Nothing works. We are forced to reboot. This is on a 4 processor Xeon Dell server, and when it reaches three locked up processes (Currently taking less than 4 hours!!!) We have to reboot. Does anyone have any suggestions for repair or workaround (Killing off these processes somehow?)

Does anyone have any suggestions about what to do about this, or at least tests I could try to narrow down the possible causes. Would it help to upgrade MySQL to a later version of 3 or to version 4? Or should I scrap MySQL and try PostgreSQL? - Original Message - From: Bruno Prior [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Wednesday, November 21, 2001 10:05 PM Subject: Stalled MySQL process causing high CPU load I am a MySQL novice, so there may be a simple explanation for this. But I have been unable to find one in the list archives, although several people seem to have had similar problems. I am running MySQL 3.23.36 from the package that comes with Mandrake linux 8.0. I am using linux software-RAID mirroring, which required upgrading the kernel to 2.4.6-ac2. The hardware is relatively limited (Duron 800, 128Mb RAM), but so are our MySQL requirements. I currently run 2 databases from it. One is a home-grown contacts and document management database with around 20 tables, none with more than 1,000 records, which I migrated off MS Access 2000. The other is the tables (around 30 or so) required for phpgrouware, which I am testing, and consequently have very few records in any of the tables. phpgroupware was the first to be set up, and shortly after I started trialling it, I started having a problem with random MySQL processes suddenly going into a spin and consuming all the CPU time (around 95% according to top), consequently slowing the machine dramatically. According to ps, the stalled process is a sibling of the process whose pid is stored in the pid file, but the process does not respond in any way to mysqladmin. the process cannot be killed with mysqladmin or kill, and attempts to shutdown the database with mysqladmin or safe-mysql (called from the init script) go into a permanent loop. The only way I can get out of it is to reboot the server. What makes this particularly hard to track down is that it often occurs when no one is even using the database. It occurs with both databases, so I don't think it is caused by PHP or MyODBC, which are used to connect to the two databases. Nor is the load real - these lockups usually occur when there is little happening on the server, and nothing happening with MySQL. Nor do I think it is a lock problem - it has occurred frequently when I have been the only person accessing the server. To avoid posting all my vital statistics to the mailing list, I have put the output of various mysqladmin commands on our server, in the hope that someone might like to take a look to see if I have an obvious problem with my configuration. The output of mysqladmin version, extended-status, variables and processlist are on http://www.summerleaze.co.uk respectively at /mysql-vers.txt, /mysql-status.txt, /mysql-vars.txt and /mysql-process. I hope I have provided sufficient information. Does anyone have any idea what might be causing this?

Re: mysql process running
As far as I know, this is on the wishlist, but has not been implemented - ie, a thread should die if the client disconnects. You'll probably need to run mysqladmin kill xxx, where is the offending thread id. regards, P On 26 Feb 2001 [EMAIL PROTECTED] wrote: Hi Everybody, I am a web developer (Apache ,Perl Mysql) , I am facing a problem , i have a program that runs a query on a text field and displays results , but since the database is huge sometimes apache sends a timeout to the client(browser) but my problem is that when i check the process list the mysqld is still running that query , how do i stop mysql from running the query once the perl program is stopped .Are there any server parameters that i have to tune i am using Mysql version 3.22.32 Thanks in Advance Kiran __ 123India.com - India's Premier Portal Get your Free Email Account at http://www.123india.com - Before posting, please check: http://www.mysql.com/manual.php (the manual) http://lists.mysql.com/ (the list archive) To request this thread, e-mail [EMAIL PROTECTED] To unsubscribe, e-mail [EMAIL PROTECTED] Trouble unsubscribing?

RE: mysql process running
Oh... Isn't ModAuthMySQL used for HTTP authentication against a mysql database ? I can't see how that could influence queries running from within a mod_perl/CGI script...

starting second mysql process gives process already exists error
Hi, I need to start 2 mysql server processes on the same box (Redhat Linux release 6.2), using the following 2 commands: bin/safe_mysqld -u root --socket=/tmp/test1.sock --port=9000 and bin/safe_mysqld -u root --socket=/tmp/test2.sock --port=9020 Previously I was using mysql 3.23.27 beta and it works fine. Now I'm switching over to the newer version 3.23.32, and I am not able to start the second process any more. The second command keeps giving me "A mysqld process already exists" message. I look into the .err file and the first command gives: 010215 17:52:50 mysqld started /usr/local/mysql-3.23.32-pc-linux-gnu-i686/bin/mysqld: ready for connections while the second gives: A mysqld process already exists at Thu Feb 15 17:53:20 SGT 2001 Is there any special setting that I need to make to solve the problem?. Any help very much appreciated. Thanks.

Usually you would start the second mysqld using another data directory. safe_mysqld places a .pid file in its data (.../var) directory which it checks for when starting again. If you have separate data directories, each will contain one .pid file and it works fine.
