-------- Recommendations -----------------------------------------------------
General recommendations:
    Run OPTIMIZE TABLE to defragment tables for better performance
    MySQL started within last 24 hours - recommendations may be inaccurate
    Enable the slow query log to troubleshoot bad queries.
    Do not forget to disable slow query logging after troubleshooting
   - For MySQL 5.0 http://dev.mysql.com/doc/refman/5.0/en/slow-query-log.html
   - For MySQL 5.1 http://dev.mysql.com/doc/refman/5.1/en/slow-query-log.html
   - For MySQL 5.5 http://dev.mysql.com/doc/refman/5.5/en/slow-query-log.html
   - For MySQL 5.6 http://dev.mysql.com/doc/refman/5.6/en/slow-query-log.html
    When making adjustments, make tmp_table_size/max_heap_table_size equal
    Reduce your SELECT DISTINCT queries without LIMIT clauses
    Set thread_cache_size to 4 as a starting value
    Increase table_open_cache gradually to avoid file descriptor limits
    Read this before increasing table_open_cache over 64: http://bit.ly/1mi7c4C
Variables to adjust:
    query_cache_size (>= 8M)
    tmp_table_size (> 16M, increase tmp_table_size)
    max_heap_table_size (> 16M, increase max_heap_table_size)
    thread_cache_size (start at 4)
    table_open_cache (> 400)

Hello,

Can you please try to update following value in your my.cnf file and run your mysqlmymonlite scripts again after 24 hours

Code:
key_buffer_size = 150M
query_cache_limit = 1M
query_cache_size = 30M
query_cache_type = 1
table_open_cache = 1000
thread_cache_size = 16
tmp_table_size = 50M
max_heap_table_size = 50M

Hello :)

Please ensure you let MySQL run for at least 24 hours before running a tuner to ensure accurate results.

Thank you.
