-------- Recommendations ---------------------------------------------------------------------------
General recommendations:
Run OPTIMIZE TABLE to defragment tables for better performance
OPTIMIZE TABLE `veritabani_vt`.`kanal_log`; -- can free 194 MB
Total freed space after theses OPTIMIZE TABLE : 194 Mb
Restrict Host for user@% to user@SpecificDNSorIp
MySQL was started within the last 24 hours - recommendations may be inaccurate
Configure your accounts with ip or subnets only, then update your configuration with skip-name-resolve=1
Increasing the query_cache size over 128M may reduce performance
Performance schema should be activated for better diagnostics
Consider installing Sys schema from https://github.com/mysql/mysql-sys for MySQL
Consider installing Sys schema from https://github.com/good-dba/mariadb-sys for MariaDB
Before changing innodb_log_file_size and/or innodb_log_files_in_group read this: https://bit.ly/2TcGgtU
Variables to adjust:
query_cache_size (=0)
query_cache_type (=0)
query_cache_size (> 256M) [see warning above]
performance_schema = ON enable PFS
innodb_log_file_size should be (=3G) if possible, so InnoDB total log files size equals to 25% of buffer pool size.
innodb_buffer_pool_instances(=30)

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

MySQL Version 10.4.7-MariaDB-1:10.4.7+maria~bionic-log x86_64

Uptime = 0 days 4 hrs 39 min 46 sec
Avg. qps = 1408
Total Questions = 23644056
Threads Connected = 15

Warning: Server has not been running for at least 48hrs.
It may not be safe to use 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 = 10.000000 sec.
You have 17 out of 23644183 that take longer than 10.000000 sec. to complete
Your long_query_time seems to be fine

BINARY UPDATE LOG
The binary update log is enabled
Binlog sync is not enabled, you could loose binlog records during a server crash

WORKER THREADS
Current thread_cache_size = 128
Current threads_cached = 110
Current threads_per_sec = 0
Historic threads_per_sec = 0
Your thread_cache_size is fine

MAX CONNECTIONS
Current max_connections = 1000
Current threads_connected = 24
Historic max_used_connections = 153
The number of used connections is 15% of the configured maximum.
Your max_connections variable seems to be fine.

INNODB STATUS
Current InnoDB index space = 1.88 G
Current InnoDB data space = 9.39 G
Current InnoDB buffer pool free = 65 %
Current innodb_buffer_pool_size = 30.00 G
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 : 31.51 G
Configured Max Per-thread Buffers : 7.38 G
Configured Max Global Buffers : 30.38 G
Configured Max Memory Limit : 37.77 G
Physical Memory : 47.16 G
Max memory limit seem to be within acceptable norms

KEY BUFFER
No key reads?!
Seriously look into using some indexes
Current MyISAM index space = 0 bytes
Current key_buffer_size = 128 M
Key cache miss rate is 1 : 0
Key buffer free ratio = 81 %
Your key_buffer_size seems to be fine

QUERY CACHE
Query cache is enabled
Current query_cache_size = 256 M
Current query_cache_used = 151 M
Current query_cache_limit = 512 K
Current Query cache Memory fill ratio = 59.12 %
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 = 4 M
Current read_rnd_buffer_size = 1 M
Sort buffer seems to be fine

JOINS
Current join_buffer_size = 260.00 K
You have had 23 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 = 5056 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 = 2000 tables
Current table_definition_cache = 400 tables
You have a total of 327 tables
You have 1033 open tables.
The table_cache value seems to be fine

TEMP TABLES
Current max_heap_table_size = 64 M
Current tmp_table_size = 64 M
Of 296408 temp tables, 2% were created on disk
Created disk tmp tables ratio seems fine

TABLE SCANS
Current read_buffer_size = 2 M
Current table scan ratio = 27 : 1
read_buffer_size seems to be fine

TABLE LOCKING
Current Lock Wait ratio = 0 : 23647353
Your table locking seems to be fine
