Tuning Primer Kurulumu ve Kullanımı
Tuning Primer bir Mysql Tuner Alternatifi , aşağıdaki komutları sırası ile dosyasını indirip çalıştırabilirsiniz. Mysql Tuner kadar olmasada yeterli bilgiler mevcut ve kullanmaya değer.
[root@ayhanarda ~]# cd /usr/local/bin
[root@ayhanarda bin]# wget https://launchpadlibrarian.net/78745738/tuning-primer.sh
Şimdi sıra çalıştırmaya geldi.
[root@ayhanarda bin]# tuning-primer.sh
Çalıştırıldığında mysql in conf u ile elde ettiği değerleri en iyi optimizasyon için karşılaştırarak size öneriler sunuyor.
Mysql in versiyonundan ne kadar süredir servis verdiğine , açık olduğu son süre içinde kaç query ye cevap verdiğine, anlık bağlantı sayısına , slow query olup olmadığına , cache size ınızın yeterli olup olmadığına , max connections değerinizin anlık değerinizi karşılayıp karşılamadığına , memory kullanımınıza , join lerinize , temp alanınıza , tablo lock sayınıza kadar ölçüp biçip size öneriler sunuyor. Örneğin ben çaqlıştırdımda çıktısı aşağıdaki gibi oldu.
Ancak öncesinde 48 saat kadar mysql servisinizin açık olması daha doğru sonuçlar almanızı sağlayacaktır.
MySQL Version 10.0.34-MariaDB x86_64
Uptime = 1 days 18 hrs 21 min 54 sec
Avg. qps = 1402
Total Questions = 213875408
Threads Connected = 34
SLOW QUERIES
The slow query log is NOT enabled.
Current long_query_time = 10.000000 sec.
You have 8 out of 213875496 that take longer than 10.000000 sec. to complete
Your long_query_time seems to be fine
WORKER THREADS
Current thread_cache_size = 200
Current threads_cached = 103
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 = 35
Historic max_used_connections = 137
The number of used connections is 68% of the configured maximum.
Your max_connections variable seems to be fine.
No InnoDB Support Enabled!
MEMORY USAGE
Max Memory Ever Allocated : 13.54 G
Configured Max Per-thread Buffers : 8.38 G
Configured Max Global Buffers : 7.79 G
Configured Max Memory Limit : 16.18 G
Physical Memory : 23.36 G
Max memory limit seem to be within acceptable norms
KEY BUFFER
Current MyISAM index space = 1.53 G
Current key_buffer_size = 1.00 G
Key cache miss rate is 1 : 99348
Key buffer free ratio = 54 %
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 = 800 M
Current query_cache_used = 800 M
Current query_cache_limit = 100 M
Current Query cache Memory fill ratio = 100.00 %
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 = 1 M
Current read_rnd_buffer_size = 768 K
Sort buffer seems to be fine
JOINS
/usr/local/bin/tuning-primer.sh: line 402: export: `2097152′: not a valid identifier
Current join_buffer_size = 40.00 M
You have had 576657 queries where a join could not use an index properly
You have had 1303 joins without keys that check for key usage after each row
join_buffer_size >= 4 M
This is not advised
You should enable “log-queries-not-using-indexes”
Then look for non indexed joins in the slow query log.
OPEN FILES LIMIT
Current open_files_limit = 138451 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_open_cache = 69120 tables
Current table_definition_cache = 65960 tables
You have a total of 59378 tables
You have 65487 open tables.
The table_cache value seems to be fine
TEMP TABLES
Current max_heap_table_size = 256 M
Current tmp_table_size = 1.46 G
Of 17855233 temp tables, 32% 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 = 309 : 1
read_buffer_size seems to be fine
TABLE LOCKING
Current Lock Wait ratio = 1 : 1582
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’
