Ubuntu 22.04 - implementing MySQL Slow Query Log Not Capturing Queries as Expected
I'm wondering if anyone has experience with I'm learning this framework and I'm relatively new to this, so bear with me... I'm currently working with MySQL on Ubuntu 22.04, and I've enabled the slow query log to help identify performance bottlenecks. I set the parameters in my `my.cnf` file as follows: ```ini [mysqld] slow_query_log = 1 slow_query_log_file = /var/log/mysql/slow-query.log long_query_time = 2 log_queries_not_using_indexes = 1 ``` After restarting the MySQL service with `sudo systemctl restart mysql`, I expected to see slow queries logged after running some intentionally slow queries. However, the slow-query.log file remains empty, and I'm puzzled by this behavior. I verified the file permissions on the log file with: ```bash ls -l /var/log/mysql/slow-query.log ``` The output shows that the MySQL user has write permissions, so I'm not sure why queries aren't being logged. I also checked the MySQL behavior log for any related warnings or errors but found nothing unusual. To troubleshoot further, I executed a few slow queries manually: ```sql SELECT SLEEP(3); SELECT * FROM my_table WHERE column1 = 'nonexistent'; ``` Yet, no entries were created in the slow-query.log. I even tried running `SHOW VARIABLES LIKE 'slow_query_log%';` to confirm that the settings were applied correctly, and it returned: ``` +----------------------+-------+ | Variable_name | Value | +----------------------+-------+ | slow_query_log | ON | | slow_query_log_file | /var/log/mysql/slow-query.log | | log_queries_not_using_indexes | ON | | long_query_time | 2 | +----------------------+-------+ ``` Everything seems correct, but I still need to see any logged queries. Is there something I'm missing, or could there be another configuration that overrides this behavior? Any help would be greatly appreciated! This is part of a larger CLI tool I'm building. How would you solve this? Is there a better approach? Thanks for taking the time to read this! How would you solve this?
