anladım teşekkür ederim
peki zaman zaman load da aşırı yükselme oluyor 40'a 50'ye varan şekilde
genel itibariyle 0-5 arası gidip geliyor fakat zaman zaman dediğim gibi load da aşırı yükselme oluyor baktığım zaman kayda değer denilebilecek oranda saldırı da olmuyor acaba bu neden kaynaklanabilir bunu nasıl öğrenebiliriz
Bunun dışında önerileriniz var mı? Server load vs gayet normal bu arada, bir sorun yok, hız gayet iyi.. Sadece donanımdan tam performans alabilmek amaçlı optimizasyon yapiyorum. [mysqld]

SLOW QUERIES
Current long_query_time = 10 sec.
You have 1393 out of 666926316 that take longer than 10 sec. to complete
The slow query log is NOT enabled.
Your long_query_time may be too high, I typically set this under 5 sec.
WORKER THREADS
Current thread_cache_size = 0
Current threads_cached = 0
Current threads_per_sec = 3
Historic threads_per_sec = 1
Threads created per/sec are overrunning threads cached
You should raise thread_cache_size
MAX CONNECTIONS
Current max_connections = 500
Current threads_connected = 8
Historic max_used_connections = 105
The number of used connections is 21% of the configured maximum.
Your max_connections variable seems to be fine.
MEMORY USAGE
Max Memory Ever Allocated : 300 M
Configured Max Per-thread Buffers : 1 G
Configured Max Global Buffers : 17 M
Configured Max Memory Limit : 1 G
Physical Memory : 1.97 G
Max memory limit seem to be within acceptable norms
KEY BUFFER
Current MyISAM index space = 110 M
Current key_buffer_size = 7 M
Key cache miss rate is 1 : 133
Key buffer fill ratio = 50.00 %
Your key_buffer_size seems to be too high.
Perhaps you can use these resources elsewhere
QUERY CACHE
Query cache is supported but not enabled
Perhaps you should set the query_cache_size
SORT OPERATIONS
Current sort_buffer_size = 2 M
Current record/read_rnd_buffer_size = 256 K
Sort buffer seems to be fine
JOINS
Current join_buffer_size = 132.00 K
You have had 2733 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 = 4096 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 = 64 tables
You have a total of 8898 tables
You have 64 open tables.
Current table_cache hit rate is 0%, 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 = 32 M
Of 489409 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 = 128 K
Current table scan ratio = 2 : 1
read_buffer_size seems to be fine
TABLE LOCKING
Current Lock Wait ratio = 1 : 37390
Your table locking seems to be fineBir süredir tuning premier ile optimizasyon yapiyorum, sonuçların çoğunluğu yeşil renkte ama bir kaç tane kırmızı var bunlar düzelmiyor. Sanırım bunlar artık my.cnf ayarları ile düzelecek şeyler de değil zaten. Sunucudaki scriptlerin query'lerindeki yanlışlar dolayısı ile olan şeyler. Genelde php-nuke sebep oluyor böyle sorunlara, ama sunucu shared hosting sunucusu yüzlerce hesap var, php-nuke kullanmayın, yada daha düzgün scriptler yazın diyemeyiz ki müşterilere

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

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

Ciddi manada problem yaşıyorum. Memory kullamımı %50lerde geziyor ve aşağıda gördüğünüz gibi akıl almaz load averagelarına ulaşıyor... Yapabileceğiniz en iyi öneriyi yaparsanız çok ama çok memnun olurum son durumu size bildiririm. sistem yaklaşık 4 gündür ayakta... Lütfen ne yapabiliyorsak yapalım
Başka önerileriniz varsa lütfen belirtiniz.. Şimdiden çok teşekkürler..
