MySQL Version 10.0.21-MariaDB-log amd64

Uptime = 4 days 23 hrs 18 min 0 sec
Avg. qps = 12
Total Questions = 5275601
Threads Connected = 3

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

SLOW QUERIES
The slow query log is NOT enabled.
Current long_query_time = 10.000000 sec.
You have 0 out of 5275622 that take longer than 10.000000 sec. to complete
[: 0.00000000000000000000: bad number
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 = 8
Current threads_cached = 6
Current threads_per_sec = 0
Historic threads_per_sec = 0
Your thread_cache_size is fine

MAX CONNECTIONS
Current max_connections = 250
Current threads_connected = 3
Historic max_used_connections = 10
The number of used connections is 4% of the configured maximum.
You are using less than 10% of your configured max_connections.
Lowering max_connections could help to avoid an over-allocation of memory
See "MEMORY USAGE" section to make sure you are not over-allocating

INNODB STATUS
Current InnoDB index space = 384 K
Current InnoDB data space = 608 K
Current InnoDB buffer pool free = 99 %
Current innodb_buffer_pool_size = 3.00 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 : 3.57 G
Configured Max Per-thread Buffers : 3.73 G
Configured Max Global Buffers : 3.42 G
Configured Max Memory Limit : 7.16 G
Physical Memory : 8.00 G
Max memory limit seem to be within acceptable norms

KEY BUFFER
Current MyISAM index space = 0 bytes
Current key_buffer_size = 384 M
Key cache miss rate is 1 : 7261
Key buffer free ratio = 79 %
Your key_buffer_size seems to be fine

QUERY CACHE
Query cache is enabled
Current query_cache_size = 32 M
Current query_cache_used = 17 M
Current query_cache_limit = 512 K
Current Query cache Memory fill ratio = 54.57 %
Current query_cache_min_res_unit = 4 K
Query Cache is 27 % 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 = 8 M
Sort buffer seems to be fine

JOINS
Current join_buffer_size = 1.00 M
You have had 67 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 = 235233 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 = 1536 tables
Current table_definition_cache = 768 tables
You have a total of 11 tables
You have 427 open tables.
The table_cache value seems to be fine

TEMP TABLES
Current max_heap_table_size = 1.00 G
Current tmp_table_size = 1.00 G
Of 54408 temp tables, 50% were created on disk
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 = 2 M
Current table scan ratio = 10 : 1
read_buffer_size seems to be fine

TABLE LOCKING
Current Lock Wait ratio = 1 : 45460
Your table locking seems to be fine
