MySQL Monitoring

Feature

Germain is configured to monitor the uptime and performance of MySQL database instances and servers.

Database availability

Monitor the availability of the MySQL database to ensure it is up and running. Track uptime and receive alerts if the database goes down or experiences any connectivity issues.

Performance metrics

Monitor key performance metrics of the MySQL database, including CPU usage, memory utilization, disk I/O, and network traffic. These metrics help identify any bottlenecks or resource constraints that could impact the performance of the database.

Query performance

Monitor the performance of SQL queries executed against the MySQL database. Track metrics such as query response time, execution plans, and index usage. Identify slow-running queries and optimize their performance to improve overall database efficiency.

Database connections

Monitor the number of active database connections and track connection usage. Identify any connection leaks or excessive connections that could impact the performance and scalability of the database.

Disk space and tablespace utilization

Monitor the disk space usage of the MySQL database and its tablespaces. Ensure that there is sufficient disk space available for data storage and log files. Identify any tablespaces that are running out of space and take necessary actions to prevent data issues.

Backup and recovery

Monitor the backup and recovery processes of the MySQL database. Ensure that regular backups are performed successfully and monitor the backup completion status. Track recovery times in case of any database failures or data corruption.

Error and event logs

Monitor MySQL error logs and event logs to identify and resolve any issues or errors that occur within the database. Log and track error messages, warnings, and informational events for troubleshooting and proactive maintenance.

Server and database configuration

Monitor server and database configuration settings to ensure they are optimized for performance and security. Keep track of any changes made to the configuration and validate their impact on the database.

Configuration

For basic monitoring of a single instance, Germain utilizes a regular database user account with CONNECT permissions.

MySQL (version 5.7.16) requires specific system parameters to be set using the RDS console. Please note that Germain has the capability to monitor any other MySQL tables, whether they are system tables or data tables. The requirements mentioned below represent the bare minimum requirements, but they can be extended to include monitoring of any other tables.
