Tamanhos de banco de dados MySQL Workbench

12

Estou tentando encontrar o tamanho total no disco rígido que todos os meus bancos de dados MySQL Workbench estão usando.

Alguém sabe de uma maneira fácil de descobrir isso?

Se nada mais, o local padrão que o mysql / workbench usa para salvar os dados brutos em uma máquina Windows?

Desde já, obrigado! Quintis

Eu tenho algumas consultas que você pode executar no arquivo Information_SCHEMA

Execute isso para obter o total de dados do MySQL e uso de índice por mecanismo de armazenamento

SELECT IFNULL(B.engine,'Total') "Storage Engine",
CONCAT(LPAD(REPLACE(FORMAT(B.DSize/POWER(1024,pw),3),',',''),17,' '),' ',
SUBSTR(' KMGTP',pw+1,1),'B') "Data Size", CONCAT(LPAD(REPLACE(
FORMAT(B.ISize/POWER(1024,pw),3),',',''),17,' '),' ',
SUBSTR(' KMGTP',pw+1,1),'B') "Index Size", CONCAT(LPAD(REPLACE(
FORMAT(B.TSize/POWER(1024,pw),3),',',''),17,' '),' ',
SUBSTR(' KMGTP',pw+1,1),'B') "Table Size" FROM
(SELECT engine,SUM(data_length) DSize,SUM(index_length) ISize,
SUM(data_length+index_length) TSize FROM
information_schema.tables WHERE table_schema NOT IN
('mysql','information_schema','performance_schema') AND
engine IS NOT NULL GROUP BY engine WITH ROLLUP) B,
(SELECT 3 pw) A ORDER BY TSize;

EMBARGO

Em cada consulta, você verá (SELECT 3 pw). O pw significa Power Of 1024 para exibir os resultados.

  • (SELECT 0 pw) exibirá o relatório em bytes
  • (SELECT 1 pw) exibirá o relatório em KiloBytes
  • (SELECT 2 pw) exibirá o relatório em MegaBytes
  • (SELECT 3 pw) exibirá o relatório em GigaBytes
  • (SELECT 4 pw) exibirá o relatório em TeraBytes
  • (SELECT 5 pw) exibirá o relatório em PetaBytes (entre em contato comigo se você executar este)

Aqui está uma consulta de relatório com um pouco menos de formatação:

SELECT IFNULL(db,'Total') "Database",
datsum / power(1024,pw) "Data Size",
ndxsum / power(1024,pw) "Index Size",
totsum / power(1024,pw) "Total"
FROM (SELECT db,SUM(dat) datsum,SUM(ndx) ndxsum,SUM(dat+ndx) totsum
FROM (SELECT table_schema db,data_length dat,index_length ndx
FROM information_schema.tables WHERE engine IS NOT NULL
AND table_schema NOT IN ('information_schema','mysql')) AA
GROUP BY db WITH ROLLUP) A,(SELECT 1 pw) B;

De uma chance !!!

ATUALIZAR

Acabei de executar a primeira consulta como está no banco de dados de um cliente

mysql> SELECT IFNULL(B.engine,'Total') "Storage Engine",
    -> CONCAT(LPAD(REPLACE(FORMAT(B.DSize/POWER(1024,pw),3),',',''),17,' '),' ',

    -> SUBSTR(' KMGTP',pw+1,1),'B') "Index Size", CONCAT(LPAD(REPLACE(
    -> FORMAT(B.TSize/POWER(1024,pw),3),',',''),17,' '),' ',
    -> SUBSTR(' KMGTP',pw+1,1),'B') "Table Size" FROM

Funciona como está.

Estou usando information_schema.partitions: há alguma diferença, por favor?
gbn 1/12/11
@gbn - As consultas segregam por engine, que não é uma coluna em information_schema.partitions. Fora isso, o information_schema.partitions captura todas as tabelas, mesmo as não particionadas. Lembre-se de excluir information_schemae mysqldas cláusulas WHERE a verificação de table_schema.

Eu tive alguns erros com o código que você forneceu, mas não tenho experiência suficiente para saber como depurá-los. Encontrei outro código on-line SELECT table_schema, sum(data_length) / 1024 / 1024 "data", sum(index_length) / 1024 / 1024 "index", sum( data_length + index_length ) / 1024 / 1024 "total" FROM information_schema.TABLES GROUP BY table_schema;. Parece que isso funciona? Toda a consulta information_schema / table_schema é nova para mim. (Se você não pode dizer, eu sou muito novo nisso tudo :) Obrigado!
