mysql cpu usage
hi everybody, PLATFORM: MySQL 4.1.8 version,OS:windowsXP We are working on a project that requires MySQL database monitoring. As part of it we monitor the network traffic to and from MySQL,harddisk space used by Mysql ,primary memory used by it and so on.As part of it we need to find the 'amount of cpu used' by MySQL . So if any one has information regarding it, please help us.It helps extremely in completing our project.We need to do JAVA programming with the information you provide.So give information,so that we could use it in our java programming.

Re: max key file length

You can read the key file, following the file layout as given by the above mentioned functions. In that case, max_key_file_length is itself part of the key file. You just need to figure out, at which offset it is. Regards, Ingo -- Ingo Strüwing, Senior Software Developer MySQL AB, www.mysql.com Office: +49 30 43672407 Are you MySQL certified? www.mysql.com/certification Respected sir, Thank you for your reply.You suggested me that both key_reflength and max_key_file_length can be read from key file.We just need to find the offset at which they are stored in key file.But I have searched all files containing key as part of their name in MySQL 4.1.9 folder for max_key_file_length and all those files all c or c++ program files. Then what do you mean by finding offset?Please once again explain in detail what key file is and what it contains. Thanking you, sirisha. Yahoo! India Matrimony: Find your life partneronline.
ms sql server to mysql migration
hello, The platform we are working is Mysql 4.1.8 version and Windows XP os. In ms sql server the space used and free space available for each database is obtained through 'sp_spaceused'procedure( built in ). Primary memory used by ms sql server and related services like query browser is obtained by sysprocesses table.It gives primary memory used in terms of pages in cache. The cpu used by ms sql server is obtained through spt_monitor table. similarly my friends who are working on oracle obtained all the above values from system tables for oracle. so both of them that is those working on ms sql server and oracle could use them directly in java programs. Are there any system tables in mysql that give info. about the above issues.If so please suggest them. If not please suggest us a way to get info. about above issues so that we can use them in our java programs. Thanks in advance. Yahoo!

innodb tablespaces
We are working with mysql 4.1.8 version and windows XP os. In that version the default amount of tablespace for data files and index files is given as data_file_path=ibdata1:10M .we then executed 'show table status' command and got innodb freespace:4092 KB (in comment column) We then created another tablespace as data_file_path=ibdata1:10M;ibdata2:5M . Then we executed the following statements use sample/* user defined database*/ show table status /*we want free space in tablespace and we saw in manual that comment column of of show table status gives that.*/ We got in comment column innodb free space=9212 KB (nearly 9 MB) Then we removed ibdata2 manually from 'data' directory and also deleted the ibdata2:5M from my.ini file and again created ibdata2 with 7MB size as follows data_file_path=ibdata1:10M;ibdata2=7M Again we saw show table status output. It gave innodb freespace:16380KB (nearly 16MB) We have done it many times i.e removing ibdata2 and again adding it. But the comment column gave always the aggregate value as u can see from above output where the freespace is given as 16MB when it should be 11MB(4MB+7MB). Why did this occur?Should we not remove the ibdata2 file once it is created?If at all if we want to remove it,what are the places from where we have to remove it? Does show table status always give correct values? Thanking you, yours sincerely, sirisha. Yahoo! India Matrimony: Find your life partneronline.
show table status
hello everybody, Mysql version:4.1.8 OS:windows XP data_file_path:ibdata1:10M in my.ini file /* which is default value*/ As every one knew the data and index files of all innodb tables are stored in ibdata1(in this case). We created some user defined tables(innodb type).The number of user defined tables does not exceed 10.The size of each table also does not exceed 10 rows. We executed 'show table status' command and it gave innodb freespace:4092 KB. What does that mean?How come system tables and user defined tables(which are not more than 10) occupy 6MB?Does mysql does 10MB ibdata1 into partitions of 6MB and 4MB?If any one knew anything regarding this issue please answer immediately.

error 1114 appearing for some tables and not for other tables
hello everybody, We are working on mysql 4.1.8 version and windows XP platform. As every one knew the default table type here is innodb.All innodb data files and index files are stored in ibdata1 tablespace. We started creating user defined tables called sam1 consisting of 750 rows and 10 columns.All columns type is int.Then we did not get any problem.Next we created table sam2 with 10 columns of 'decimal' type and by the time we inserted 88 rows we got error 1114(HY000):the table 'sam2' is full. Why was that so,in one table we could insert 750 rows(The table size is shown as 98304 by show table status) while other one with decimal type values was filled for just 88 inserts(Table size is given as 16384 by 'show table status' command).Does mysql put max limit on table size?We searched all types of mysql variables but we could not find the answer. Please give the details of error 1114. Yahoo! India Matrimony: Find your life partneronline.

mysql tablespace monitoring
First of all, thanks for the mailing list for giving details about myisamchk.we used them but we got some errors which I have reported in 'myisamchk errors' mail to mysql. At present we are working in mysql 3.23.32 ,windows xp os. Are there any system tables that store mysql related info.(like memory related issues etc). Are there any other ways to find memory used and free memory available by data tables,log files,temporary tables.We want the information so that we can use it in programs.Information available through commands could not be used in programming(For ex:myisamchk works with single table.we need to monitor entire datadirectory so we need to write programs.) Thanking you, yours sincerely, sirisha. PS:FIRST OF ALL ARE THERE ANY SYSTEM TABLES THOSE STORE THE ABOVE RELATED INFORMATION.IF NOT PLEASE MENTION IT. Yahoo!

hello everybody, I used myisamchk /path/to/datadir/mysql/*.* to find memory already in use and free memory available for all tables in 'mysql' database.where mysql in above path refers to mysql database. I got two types of errors for all tables in that directory. They are myisamchk:error: -1 when opening myisam_table 'abcd.MYD' myisamchk1 error:'abcd.frm' doen't have a correct index definition.You need to create it before u can do a repair.I am using Red hat linux mysql version.

if you know please answer immediately
I am a student and we are doing a project in mysql database monitoring. 1 . we found that the memory used and free memory available for tables in individual database is given by myisamchk -d -v command.But we don't have any information about the tables or files myisamchk works on.so please give information if available. 2 . we are required to find memory used and free memory available for all types of tables,log files of mysql,temporary tables used by mysql database.We don't get help from any of our professors since they don't have working experience in mysql. please give details to any one of the above questions if not all the questions.

if you know the answer,please answer immediately contd
I am a student and we are doing project in mysql database monitoring.Yesterday I posted my doubts regarding that project to this forum. I got reply from Mr.Harish, his suggestion is to use show table status database name or myisamchk -d -v table_name .Thank you sir for your reply. Actually i haven't made the queations clearer. This is what we have to do in our project,we have to monitor mysql database and continously calculate memory already used by and free memory available for each database(or table),each log file,each temporary table(mysql temporary tables).If free memory is less than a certain percentage we have to send an alert box to the user asking him to backup those tables and logfiles. So we need information about both used space and free space not just the size of those tables or log files. I asked to give details about the tables myisamchk works on.By that question I mean that because Myisamchk is giving details about memory used by tables those details should have been stored in some system tables or files.We need the names of those system tables or files. So if you have information regarding any of the above issues please answer immediately. yours sincerely, sirisha. Yahoo! India Matrimony: Find your life partneronline.
