Stay on top of MySQL key performance metrics. Keep everyone in the know with integration with Slack, PagerDuty and more.

MySQl - High Query Execution Time

This alert monitors the average execution time of queries in your ySQL database. High query execution times can indicate performance bottlenecks, inefficient queries, or resource contention, potentially degrading application performance. The alert is triggered when the count of slow queries exceeds 10 in last 1m. Monitoring this metric helps ensure that your database operations remain efficient, reducing the risk of slow application responses and user dissatisfaction. Customization Guidance: - Threshold: Adjust the threshold based on the acceptable query execution times for your application’s performance requirements. - Monitoring Period: Modify the monitoring period to reflect typical query patterns, such as peak traffic times or batch processing intervals. - Notification Frequency: Configure notifications to provide timely alerts without causing alert fatigue during transient spikes. Action: If this alert is triggered, consider analyzing slow queries using performance profiling tools, optimizing query structures, adding indexes, or scaling database resources to improve query execution times.

MySQl - High Query Cache Hit Ratio

This alert monitors the query cache hit ratio for a MySQL database. A high query cache hit ratio indicates that most queries are being served from the cache, which can be beneficial for performance. However, an excessively high ratio might suggest underutilization of the database for complex queries or unnecessary caching. The alert is triggered when the query cache hit ratio exceeds 70% over a 10-minute period. Monitoring this metric helps ensure that the database query performance is balanced and the cache configuration is optimized to prevent potential performance bottlenecks. Customization Guidance: - Threshold: Adjust the threshold based on your workload. A lower threshold may help detect over-caching earlier in scenarios requiring real-time updates. - Monitoring Period: Modify the monitoring period to align with the typical query execution patterns of your application. - Notification Frequency: Set notifications to alert on significant or sustained periods of high cache hit ratios to avoid excessive notifications. Action: If this alert is triggered, consider reviewing query patterns and cache configuration settings. You may need to adjust the query cache size or exclude specific queries from caching to improve database performance.

MySQL- Too Many Connections

This alert monitors the number of active connections to a MySQL database. Too many connections can indicate excessive demand on the database, which may lead to resource exhaustion and degraded performance. The alert is triggered when the number of active connections exceeds 90% of the `max_connections` setting over a 10-minute period. Monitoring this metric helps ensure that your database can handle concurrent connections effectively and prevents potential outages due to connection saturation. Customization Guidance: - Threshold: Adjust the threshold based on your database's `max_connections` setting and typical usage patterns. - Monitoring Period: Modify the monitoring period to reflect periods of peak connection usage for your application. - Notification Frequency: Set notifications to alert on sustained or critical spikes in connections, avoiding excessive alerts during transient spikes. Action: If this alert is triggered, consider investigating the sources of high connection usage. Actions may include optimizing application connection pooling, increasing the `max_connections` setting, or identifying and resolving inefficient queries causing prolonged connections.

MySQl - High Failed Connection Attempts

This alert monitors the number of failed connection attempts to a MySQL database. A high number of failed connection attempts can indicate misconfigured applications, credential issues, or potential security threats such as brute-force attacks. The alert is triggered when the number of failed connection attempts exceeds 30 within a 10-minute period. Monitoring this metric helps ensure database security and availability by identifying and addressing unauthorized access attempts or configuration errors. Customization Guidance: - Threshold: Adjust the threshold based on your application's typical connection behavior and expected activity. - Monitoring Period: Modify the monitoring period to align with patterns of access and usage in your environment. - Notification Frequency: Set notifications to alert promptly during suspicious activity while avoiding excessive alerts during transient issues. Action: If this alert is triggered, consider reviewing the database logs to identify the source of failed attempts. Check for incorrect application configurations, update credentials if necessary, and investigate potential security threats. Implement measures such as IP whitelisting or enabling stronger authentication mechanisms if needed.
