pt-query-digest --processlist
Hi guys, I'm trying to use pt-query-digest on one of our Prod servers. The problem our slow log is disabled, no tcpdump is installed and I decided to use --processlist parameter which I never tried before. pt-query-digest version 2.2.2 I run to connect to remote node: pt-query-digest --processlist h=192.168.1.111,u=user -p PASSWORD --print --no-report --run-time 60 SERVER-`date +%Y%m%d-%H` I get: Unknown option: print Without --print parameter I don't have errors but I do not get any output into file. The prod server is very busy. How to make it work? Thanks, Igor -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/mysql
Re: pt-query-digest --processlist
Hi Claudio, Thanks for reply. Great. I was sure you can't enable slow log dynamically on 5.0 and 5.1. That solves my issue for 5.1 at least.

RE: mysqlimport --use-threads / mysqladmin processlist

Re: mysqlimport --use-threads / mysqladmin processlist
Yes, the rows are in primary key order, however each row contains specific integer primary keys; I'm not inserting nulls into a table where the primary key is auto increment, so I don't see why concurrent inserts would fight for similar spots (although, I'm admittedly not a MySQL hotshot, so the basis of my assumption is a *hunch* only). I'm not sure (yet) if a single-threaded operation would run into an i/o bottleneck. I didn't run mysqlimport using --use-threads=1 just yet (will do if I have the time), but when I've ran it with --use-threads=4 the import (of a ~500 MB dump) took more time than running for different processes (I've split my tab delimited dumps with split into four even pieces and imported those in four different sessions). Anyway, it seems that doing a simple import (from a dump, which isn't tab delimited, but contains complete or extended inserts) takes the same amount of time than doing a mysqlimport using --use-threads=4 and as it turns out splitting my tab delimited dump is too complex to handle gracefully, because my data contains newline characters all over the place, so I've dropped the idea of this whole mysqlimport thing for now. (I'll try the method of migrating an InnoDB database to an NDBCluster described here[1] instead.) If I have the time I'll write up a bug report, or documentation enhancement request for this.

Re: To get Processlist and Status of MySQL ?
If your mysql server is hung, crashed or otherwise unreacheable (as you first posted), you can't connect to it and request it's status and processlist - it's threaded and thus all inline. You could use GDB or something similar to go look in the execution stack, as Raj said, and if you have full query logging enabled, you can parse your logs and see what was happening at the time of the crash - although I suspect that only completed queries get logged, so the one causing the crash may not be in there. Generally, it's a good idea to use Munin, Cacti or similar tools to graph performance data all the time, so you can have a post-mortem look at stuff like did the number of connections increase in the moments before ?

Re: Getting more info from show full processlist
One way to do it (maybe the only way for selects) is to use the general log. The Id number, 30399, is the thread id. You can look up the thread id in the general log and see the entire command. But you have to have the general log running. If the command changes data (update, delete, insert) then it'll be in the bin log with the thread id. If you know what time the command was executed, you can use the --start-datetime option of mysqlbinlog. But only the general log keeps selects.

Re: Processlist full of Opening tables
Thanks for the reply. It helped alot, since I did not know where to look. I read the documentation regarding the issue and some more pages google turned up for me. I did increase my table cache to 16k and my open files are at 30k. I do run debian etch 32-bit. How would I determine what reasonable means for open files are on my system? I have 4GB Ram and a 2.6 Ghz DualCore. What also interests me is my key buffer. I have it set to 768MB: mysql show status like key%; ++--+ | Variable_name | Value| ++--+ | Key_blocks_not_flushed | 0| | Key_blocks_unused | 661370 | | Key_blocks_used| 40169| | Key_read_requests | 22935142 | | Key_reads | 65152| | Key_write_requests | 1941899 | | Key_writes | 162770 | ++--+ 7 rows in set (0.00 sec) This would mean the following: 65152 Key_reads / 22935142 Key_read_requests * 100 = 0.29 % I think this would be an reasonable value. Am I right? Regards, Samy Brent Baisley schrieb: The problem is your table cache setting. MySQL will only keep a certain amount of tables open and ready for access. Once that limit is hit, if a table that is not already open needs to be accessed, it needs to close a table to make room for opening the new table. This doesn't mean you can just set the table cache size really high. The operating system has limits as to how many file handles it can have open at one time. In mysql type this: show status like open% Your Opened_tables number is probably huge. That's how many times mysql had to open a table for access. Meaning the table wasn't opened already. The Open_tables is how many tables MySQL will keep open (table cache). You need to increase this number using the table_cache variable. set global table_cache=#; The Open_files number from the show status command is important, make sure that stays within limits of your operating system.

Re: show full processlist question
Peter, SHOW PROCESSLIST is a moment-in-time snapshot of connections and their activities. It shows you what all is going on at the instant you issue the command; it does not show you recent commands (even those that happened a second ago). Many of your queries are very likely so fast that you're just not seeing them in SHOW PROCESSLIST - if they took much time, you wouldn't be getting that 500-per-second number. Its purpose is more to show you what is going on with queries that don't run so quickly, or when your database experiences a deadlock. If you do really need to get a list of all queries that ran in a particular second, you might be able to work some magic with MySQL's general log aka the query log. You have to specifically enable that, and it is a record of ALL queries including data inserts and updates, so it can become a large file quickly - beware.

Re: maximum id of processlist
Hello. As said Guilhem Bichot. It will go up to 232 or 264 depending on your architecture (32 or 64 bit) then it will go down to 0 and grow again. There is nothing wrong with having a thread of id 0 (I had tested). I've looked though code of mysqld.cc, but haven't found any checks. The value of thread_id only increments: thd-thread_id=thread_id++; Is this a problem? No, the only problem which could happen is if thread 1 still exists when a new thread of number 232+1 == 1 is created. But that sounds unlikely.

Re: Setting custom information in processlist
Thank you very much for your reply, Jeremy. I have been searching high and low for some sort of solution in MySQL, now I can stop. In answer to your question other systems simply allow certain attributes to be set at connection time, e.g. application_name, host_name, etc. So I normally post_fix to the application_name a short date-time value which allows me to distinguish connections in the list of processes on the server.

Re: Setting custom information in processlist
Oracle has a procedure called DBMS_APPLICATION_INFO.SET_APPLICATION_INFO
that allows you to specify up to 64k of addtional information about
the current connection. It doesn't have any way to specify this
information at connect time though.
The data can be accessed in Oracle through the V$SESSION system view,
or through
userenv('CLIENT_INFO')
Something in mysql that would be similar and just as easy to implement would be:
create table process_info(ThreadID int, Information text, primary key
(ThreadID));
then in each connection do:
replace into process_info values (CONNECTION_ID(), 'Connection details here');
Add in a little cron job that removes old values from the process_info
table nightly and that should do the trick.

grepping data from show processlist in more elegant way
Hello, I have wrote a small program which's main purpose is to do change master to, slave start and after a transfer of data - slave stop. But after slave start i need to know when the transfer ends - to do this I could parse the mysql_list_processes() output for a string Has read all relay log; waiting for the I/O slave thread to update it but it is not too elegant, is there a way to do it in more elegant way? Or maybe mysql do not permit to do slave stop before the end of transmission? -- Irek Slonina -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]
SHOW PROCESSLIST State Locked - what does this mean?
Hi, Currently, I have a situation where an app makes connections (via JDBC) to a mysql server, 50 connections at once, and everything just becomes super-slow. For instance, a SELECT that should take 0.01 sec takes several minutes. SHOW PROCESSLIST says that these threads that are connections from the app are in a state Locked. The mysql manual doesn't explain this option, or even list it as a possibility (maybe I'm looking at the wrong place: http://dev.mysql.com/doc/mysql/en/SHOW_PROCESSLIST.html) The other question is what one can do about this, to prevent this locking, or even diagnose it. Thanks for your help. Jim -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]
SHOW PROCESSLIST displays incorrect slave latency in MySQL 3.23
Description: When I do 'SHOW PROCESSLIST' on my server currently, the line for 'system user' is as follows: ++-+--+-+-++---+--+ | Id | User| Host | db | Command | Time | State | Info | ++-+--+-+-++---+--+ | 495801 | system user | none | NULL| Connect | 4294967211 | Reading master update | NULL | A few minutes before, and for a number of days, it had been displaying very low ( 100s) numbers. Subtracting the number from 2 ** 32 gives what looks like a sensible figure, so this may be a signed/unsigned bug. How-To-Repeat: Hard to say; MySQL has been up for approaching 64 days - not sure if that's significant. Doing SLAVE STOP; SLAVE START; has no effect.

Try

The problem, I think, is that your client system starts swapping hard while
trying to allocate enough memory to store 81,000 rows.

processlist: state is Opening table
filter: select, mysql Solaris 3.23.40 connections using perl, jdbc, odbc. Yesterday, we experienced a rare mysqld failure where all connections where in the state=Opening table. Normally our 200+ connections are in state=sleep. The Time field from command show processlist showed each connection accumulating time. This is not the case when a connection is in the sleep mode. The number of connections was nearly 400 when we normally have over 200. The threads running about equal to number of connections. The threads created was at 1240 - normally is ~ number of connections. When I attempted a mysql.server stop, it timed out. I had to use a kill -9. I used a combination of myismcheck (db off) and check table (db on) to verify that all tables were ok. I did repair tables that were OK but terminated improperly probably due to the kill -9 command. The info column from the show processlist showed the command the user or program was executing. All of the connections were accounted for including the extra 170 connections. These extra connections accumulated from programs between the time server failed and time of restart. To me, it appears that the mysqld allowed connections, but then froze with all connections executing at the state Opening table. This is verified from programs making connections without failing. It appears all were waiting for mysqld to process the query. Just in case this matters, there are ~75 tables in this installation. On a normal day, open_tables=149 and table cache is set to 256. Prior to restarting mysqld, opened_tables was at 831. Any suggestions welcome.

Re: mysqladmin processlist and pid
Hi Tom, You can't. MySQL's own thread ids are sequential. The OS pids are random. There's no connection between them.

Hi Andrius, Yes, I've wondered about this before too, but wasn't exactly sure what it meant either. :-) So I just decided to see where this state is set in the code, and it's when the make_join_statistics() function is called.

RE: Mysql processlist sleep time
I don't believe Windows services can be started with any priority types. MySQL is on it's own box with the ASP version, which works like a dream. It's simply that whenever the PHP version is used (either as a solitary website on another box or as another website on the same box), that's when mysqld goes mad. The odd thing is that the software is effectively identical between the two languages, and has simply had functions changed as and where appropriate. I have also used the programming methods as used in the book PHP and MySQL Web Development too, as well as reading advice from MySQL Second Edition by Paul Dubois. I just wonder if this is a problem that is unable to be solved?! -Original Message- From: Adam Nelson [mailto:[EMAIL PROTECTED] Sent: 08 August 2003 17:16 To: 'Gary Broughton'; [EMAIL PROTECTED] Subject: RE: Mysql processlist sleep time I think I see the problem.

Mysql processlist sleep time
Hi all I continue to have problems with the CPU usage with MySQL and PHP under IIS 5 (Win2000). I recently rewrote our messageboards in PHP (from ASP). I now have both online separately, and if I look at the processlist, the times on the ASP version rarely hit double figures, but those on the PHP version often reach several hundred (wait and inactivity timeouts are set to 300 - I thought this would stop it?!).

Has anybody any ideas on why this can be? I cannot find out how to tell what is causing the long sleep period. Many thanks Gary

RE: Mysql processlist sleep time
exactly, NULL is a good thing. It means that php isn't constantly tearing down sessions and starting new ones.

Bug in SHOW PROCESSLIST?
Hello, all. I have noticed over the last few days that when I do a SHOW PROCESSLIST on my MySQL server the host field always reports the same host IP address or name regardless of who is making the connection. Here is a run of the command on my machine: mysql show processlist; +-+---++-+-+--+---+--+ | Id | User | Host | db | Command | Time | State | Info | +-+---++-+-+--+---+--+ | 334 | engineer | 127.0.0.1:1164 | engineering | Sleep | 235 | | NULL | | 335 | processviewer | 127.0.0.1:1313 | NULL| Sleep | 0| | NULL | | 336 | root | 127.0.0.1:1316 | NULL| Query | 0| NULL | show processlist | +-+---++-+-+--+---+--+ 3 rows in set (0.00 sec) The user 'engineering' is not connecting from my local machine but the other two are. The port for the engineer user is correct according to netstat. The server is running on my development machine which runs Windows 2000 Professional. The server is the standard Win32 binary 4.0.12-nt-log. Has anyone else seen this phenomenon?

Trouble with MySQL4, host field in show processlist
Hi, My first post here l;) Ok, here it goes. I recently installed MySQL4 and transfered all my databases there. Now, it all works great, but the host field, in show processlist command, don't work correctly. It don't display correct info from where the query has came. Example: mysql show processlist; ++--+-+--++--++--+ | Id | User | Host| db | Command| Time | State | Info | ++--+-+--++--++--+ | 32 | DELAYED | localhost | db1 | Delayed_insert | 0 | Waiting for INSERT | | | 1387 | DELAYED | localhost | db2 | Delayed_insert | 68 | Waiting for INSERT | You see the localhost, value for host. It isn't correct. These queries are from different server, not from localhost. I'm executing show processlist from localhost only. Anyone know how can i fix this, or something to show correct info ?

The change log for 4.012 mentions (Lenz Grimmer just posted this a couple of messages ago): Functionality added or changed: * `SHOW PROCESSLIST' will now include the client TCP port after the hostname to make it easier to know from which client the request originated. I guess whenever the hostname lookup fails you just see the IP address.

strange processlist
Thanks to Jeremy Zawodny for his great tool, I was able to capture this during a server meltdown at the hands of an upraded MySQL binary (From 3.23.32 to 3.23.52). My story is a famliar one -- a db (MyISAM tables) that ran fine for 3 years all of sudden brings our cpu to a halt with an upgraded binary from MySQL. RH, Linux 2.2.16-22enterprise, harmless load averages until a few respectable queries are issued and we get crippled. Never seen a processlist like this though. It happens within 30 seconds of the server getting throttled.
