MySQL and MariaDB Alerts shows alerts for one monitored MySQL or MariaDB server. Use it for focused instance-level triage.

Mini DBA MySQL MariaDB alerts

Workflow

  1. Open Alerts under the MySQL or MariaDB server.
  2. Review severity, message, and time.
  3. Open the related monitoring page for evidence.
  4. Use Configure and Copy Config to edit or copy alert policy.
  5. Use global Alerts for cross-engine alert review.

How To Use MySQL And MariaDB Alerts

Use the MySQL and MariaDB Alerts page when you want alert context for one monitored server. It is the fastest way to focus on a known affected instance without scanning alerts for every engine. This is useful for daily operational review, customer-specific managed service checks, and active incident triage.

Start with alerts that are high severity, new, repeating, or close to the time users reported a problem. Then open the related page for evidence. Activity alerts should be checked with MySQL And MariaDB Activity, storage or latency symptoms with MySQL And MariaDB I/O, transaction symptoms with MySQL And MariaDB InnoDB, and configuration concerns with MySQL And MariaDB Health Checks.

For follow-up, record the alert time, affected database or workload, owner, and action taken. This makes repeating alerts easier to reduce and gives managed service teams a clearer audit trail.

Use Copy, Export, And Import Alert Configuration when MySQL and MariaDB servers should share a standard alert profile. Review custom alert SQL and notification routing before copying between different customers, environments, or engine instances.

MySQL And MariaDB Alert FAQ

Why use this page instead of global Alerts?

This page is best for one server. Use global Alerts when prioritizing alerts across engines, customers, or server groups.

What if an alert repeats every day?

Check whether it maps to a scheduled job, backup, report, import, or accepted workload pattern before changing thresholds.

Can an alert identify root cause by itself?

Usually no. Alerts point to symptoms or thresholds. Use related monitoring pages to confirm the cause.

Alert Type Reference

The following Mini DBA MySQL and MariaDB alert detail pages explain why each alert is useful, when to enable it, how to tune thresholds, and what remediation steps to take when the alert is active. Custom Alert is included because each server Alerts page can also hold user-defined query alerts.
