OOM KILL CAN OCCUR! - vm.swappiness <= 10 (echo 10 > /proc/sys/vm/swappiness) or vm.swappiness=10 in /etc/sysctl.conf - fs.aio-max-nr > 1M (echo 1048576 > /proc/sys/fs/aio-max-nr) or fs.aio-max-nr=1048576 in /etc/sysctl.conf - performance_schema=ON - innodb_buffer_pool_size (>= 146.8M) if possible. - innodb_log_file_size should be (=32M) if possible, so InnoDB total log file size equals 25% of buffer pool size. diff --git a/examples/20260117_233902_mariadb118/mysqltuner_output.txt b/examples/20260117_233902_mariadb118/mysqltuner_output.txt deleted file mode 100644 index

OOM KILL CAN OCCUR! - vm.swappiness <= 10 (echo 10 > /proc/sys/vm/swappiness) or vm.swappiness=10 in /etc/sysctl.conf - fs.aio-max-nr > 1M (echo 1048576 > /proc/sys/fs/aio-max-nr) or fs.aio-max-nr=1048576 in /etc/sysctl.conf - performance_schema=ON - innodb_buffer_pool_size (>= 146.8M) if possible. - innodb_log_file_size should be (=32M) if possible, so InnoDB total log file size equals 25% of buffer pool size. diff --git a/examples/20260117_233902_mariadb118/report.html b/examples/20260117_233902_mariadb118/report.html deleted file mode 100644 index 7dbdf3c16..000000000 --- a/examples/20260117_233902_mariadb118/report.html +++ /dev/null @@ -1,647 +0,0 @@ - - - - - - MySQLTuner Test Report - mariadb118 - - - - -

--------- Recommendations ---------------------------------------------------------------------------
-General recommendations:
-    Consider stopping or dedicate server for additional process other than mysqld.
-    setup swappiness lower or equal to 10
-    setup Max running number events greater than 1M
-    Restrict Host for 'root'@'%' to 'root'@LimitedIPRangeOrLocalhost
-    RENAME USER 'root'@'%' TO 'root'@LimitedIPRangeOrLocalhost;
-    MySQL was started within the last 24 hours: recommendations may be inaccurate
-    Performance schema should be activated for better diagnostics
-    Be careful, increasing innodb_log_file_size / innodb_log_files_in_group means higher crash recovery mean time
-Variables to adjust:
-    DON'T APPLY SETTINGS BECAUSE THERE ARE TOO MANY PROCESSES RUNNING ON THIS SERVER. OOM KILL CAN OCCUR!
-    vm.swappiness <= 10 (echo 10 > /proc/sys/vm/swappiness) or vm.swappiness=10 in /etc/sysctl.conf
-    fs.aio-max-nr > 1M (echo 1048576 > /proc/sys/fs/aio-max-nr) or fs.aio-max-nr=1048576 in /etc/sysctl.conf
-    performance_schema=ON
-    innodb_buffer_pool_size (>= 146.8M) if possible.
-    innodb_log_file_size should be (=32M) if possible, so InnoDB total log file size equals 25% of buffer pool size.
