Merhaba arkadaslar, mysql kendi kendine restart yaptigini farkettim, ne zaman ./tuning-primer.sh calistirsam en fazla 1 saat gösteriyor.

-- MYSQL PERFORMANCE TUNING PRIMER --
- By: Matthew Montgomery -

MySQL Version 5.0.51a-24+lenny2 i486

Uptime = 0 days 0 hrs 24 min 1 sec
Avg. qps = 117
Total Questions = 169397
Threads Connected = 17

Warning: Server has not been running for at least 48hrs.
It may not be safe to use these recommendations

runtime variables effects performance visit:

SLOW QUERIES
The slow query log is NOT enabled.
Current long_query_time = 4 sec.
You have 13916 out of 169418 that take longer than 4 sec. to complete
Your long_query_time seems to be fine

BINARY UPDATE LOG
The binary update log is NOT enabled.
You will not be able to do point in time recovery
See http://dev.mysql.com/doc/refman/5.0/...-recovery.html

WORKER THREADS
Current thread_cache_size = 128
Current threads_cached = 50
Current threads_per_sec = 0
Historic threads_per_sec = 0
Your thread_cache_size is fine

MAX CONNECTIONS
Current max_connections = 500
Current threads_connected = 19
Historic max_used_connections = 68
The number of used connections is 13% of the configured maximum.
Your max_connections variable seems to be fine.

INNODB STATUS
Current InnoDB index space = 2 M
Current InnoDB data space = 2 M
Current InnoDB buffer pool free = 27 %
Current innodb_buffer_pool_size = 8 M
Depending on how much space your innodb indexes take up it may be safe
to increase this value to up to 2 / 3 of total system memory

MEMORY USAGE
Max Memory Ever Allocated : 2.43 G
Configured Max Per-thread Buffers : 16.68 G
Configured Max Global Buffers : 170 M
Configured Max Memory Limit : 16.85 G
Physical Memory : 3.91 G

nMax memory limit exceeds 90% of physical memory

KEY BUFFER
Current MyISAM index space = 616 M
Current key_buffer_size = 128 M
Key cache miss rate is 1 : 347
Key buffer free ratio = 50 %
Your key_buffer_size seems to be too high.
Perhaps you can use these resources elsewhere

QUERY CACHE
Query cache is enabled
Current query_cache_size = 32 M
Current query_cache_used = 21 M
Current query_cache_limit = 4 M
Current Query cache Memory fill ratio = 66.12 %
Current query_cache_min_res_unit = 4 K
MySQL won't cache query results that are larger than query_cache_limit in size

SORT OPERATIONS
Current sort_buffer_size = 26 M
Current read_rnd_buffer_size = 3 M
Sort buffer seems to be fine

JOINS
Current join_buffer_size = 2.00 M
You have had 1 queries where a join could not use an index properly
You should enable "log-queries-not-using-indexes"
Then look for non indexed joins in the slow query log.
If you are unable to optimize your queries you may want to increase your
join_buffer_size to accommodate larger joins in one pass.

Note! This script will still suggest raising the join_buffer_size when
ANY joins not using indexes are found.

OPEN FILES LIMIT
Current open_files_limit = 50000 files
The open_files_limit should typically be set to at least 2x-3x
that of table_cache if you have heavy MyISAM usage.
Your open_files_limit value seems to be fine

TABLE CACHE
Current table_cache value = 860 tables
You have a total of 840 tables
You have 860 open tables.
Current table_cache hit rate is 19%
, while 100% of your table cache is in use
You should probably increase your table_cache

TEMP TABLES
Current max_heap_table_size = 16 M
Current tmp_table_size = 3.99 G
Of 3094 temp tables, 18% were created on disk
Effective in-memory tmp_table_size is limited to max_heap_table_size.
Created disk tmp tables ratio seems fine

TABLE SCANS
Current read_buffer_size = 1 M
Current table scan ratio = 1460 : 1
read_buffer_size seems to be fine

TABLE LOCKING
Current Lock Wait ratio = 1 : 126
You may benefit from selective use of InnoDB.
