Uptime = days hrs min sec
Avg. qps = 5
Total Questions = 1707329

Server has been running for over 48hrs.
It should be safe to follow these recommendations

To find out more information on how each of these
runtime variables effects performance visit:

Visit http://www.mysql.com/products/enterprise/advisors.html
for info about MySQL's Enterprise Monitoring and Advisory Service

SLOW QUERIES
The slow query log is NOT enabled.
Current long_query_time = 10 sec.
You have 99 out of 1707343 that take longer than 10 sec. to complete
Your long_query_time may be too high, I typically set this under 5 sec.

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/4.1/...-recovery.html

WORKER THREADS
Current thread_cache_size = 128
Current threads_cached = 85
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 = 1
Historic max_used_connections = 86
The number of used connections is 17% of the configured maximum.
Your max_connections variable seems to be fine.

./tuning-primer.sh: line 742: [: -le: unary operator expected
./tuning-primer.sh: line 746: [: -ge: unary operator expected
MySQL won't cache query results that are larger than query_cache_limit in size

SORT OPERATIONS
./tuning-primer.sh: line 331: bc: command not found
Current sort_buffer_size = M
./tuning-primer.sh: line 331: bc: command not found
Current read_rnd_buffer_size = K
Sort buffer seems to be fine

JOINS
./tuning-primer.sh: line 331: bc: command not found
Current join_buffer_size = M
You have had 31 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 = 2558 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 = 1024 tables
You have a total of 1650 tables
You have 1022 open tables.
Current table_cache hit rate is 11%, while 99% of your table cache is in use
You should probably increase your table_cache

TEMP TABLES
./tuning-primer.sh: line 331: bc: command not found
Current max_heap_table_size = M
./tuning-primer.sh: line 331: bc: command not found
Current tmp_table_size = M
Of 91866 temp tables, 0% 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
./tuning-primer.sh: line 331: bc: command not found
Current read_buffer_size = M
Current table scan ratio = 2109 : 1
read_buffer_size seems to be fine

TABLE LOCKING
Current Lock Wait ratio = 1 : 979
You may benefit from selective use of InnoDB.
If you have long running SELECT's against MyISAM tables and perform
frequent updates consider setting 'low_priority_updates=1'

Böyle bir çıktı aldım nasıl bir yol izlemem lazım yardımcı olursan sevinirim iyinet.

-- MYSQL PERFORMANCE TUNING PRIMER --

             - By: Matthew Montgomery -



MySQL Version 5.0.32-Debian_7etch5-log i486



Uptime = 2 days 5 hrs 35 min 41 sec

Avg. qps = 30

Total Questions = 5949923

Threads Connected = 2



Server has been running for over 48hrs.

It should be safe to follow these recommendations



To find out more information on how each of these

runtime variables effects performance visit:

http://dev.mysql.com/doc/refman/5.0/en/server-system-variables.html

Visit http://www.mysql.com/products/enterprise/advisors.html

for info about MySQL's Enterprise Monitoring and Advisory Service



SLOW QUERIES

Current long_query_time = 2 sec.

You have 40630 out of 5949948 that take longer than 2 sec. to complete

The slow query log is enabled.

Your long_query_time seems to be fine



WORKER THREADS

Current thread_cache_size = 384

Current threads_cached = 133

Current threads_per_sec = 0

Historic threads_per_sec = 0

Your thread_cache_size is fine



MAX CONNECTIONS

Current max_connections = 200

Current threads_connected = 3

Historic max_used_connections = 136

The number of used connections is 68% of the configured maximum.

Your max_connections variable seems to be fine.



MEMORY USAGE

Max Memory Ever Allocated : 1 G

Configured Max Per-thread Buffers : 1 G

Configured Max Global Buffers : 306 M

Configured Max Memory Limit : 2 G

Physical Memory : 1.97 G



Max memory limit exceeds 90% of physical memory



KEY BUFFER

Current MyISAM index space = 306 M

Current key_buffer_size = 256 M

Key cache miss rate is 1 : 4036

Key buffer fill ratio = 44.00 %

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 = 40 M

Current query_cache_used = 24 M

Current query_cache_limit = 4 M

Current Query cache Memory fill ratio = 60.97 %

Current query_cache_min_res_unit = 4 K

Query Cache is 21 % fragmented

Run "FLUSH QUERY CACHE" periodically to defragment the query cache memory

If you have many small queries lower 'query_cache_min_res_unit' to reduce fragmentation.

MySQL won't cache query results that are larger than query_cache_limit in size



SORT OPERATIONS

Current sort_buffer_size = 2 M

Current record/read_rnd_buffer_size = 3 M

Sort buffer seems to be fine



JOINS

Current join_buffer_size = 2.00 M

You have had 28 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 = 2258 files

The open_files_limit should typically be set to at least 2x-3x

that of table_cache if you have heavy MyISAM usage.

You currently have open more than 75% of your open_files_limit

You should set a higher value for open_files_limit in my.cnf



TABLE CACHE

Current table_cache value = 1024 tables

You have a total of 772 tables

You have 1024 open tables.

Current table_cache hit rate is 53%, while 100% of your table cache is in use

You should probably increase your table_cache



TEMP TABLES

Current max_heap_table_size = 64 M

Current tmp_table_size = 128 M

Of 91458 temp tables, 31% were created on disk

Effective in-memory tmp_table_size is limited to max_heap_table_size.

Perhaps you should increase your tmp_table_size and/or max_heap_table_size

to reduce the number of disk-based temporary tables

Note! BLOB and TEXT columns are not allow in memory tables.

If you are using these columns raising these values might not impact your

ratio of on disk temp tables.



TABLE SCANS

Current read_buffer_size = 1 M

Current table scan ratio = 389 : 1

read_buffer_size seems to be fine



TABLE LOCKING

Current Lock Wait ratio = 1 : 15

You may benefit from selective use of InnoDB.

If you have long running SELECT's against MyISAM tables and perform

frequent updates consider setting 'low_priority_updates=1'

If you have a high concurrency of inserts on Dynamic row-length tables

consider setting 'concurrent_insert=2.

onerileriniz icin şimdiden teşekkurler
