# Misc. Performance Schema tables

This page lists the `performance_schema` tables added to standard *MySQL* by *Percona Server for MySQL* that don't exist elsewhere in the documentation.

## Performance schema tables

### `performance_schema.account_failed_login_lock_status`

The new `performance_schema.account_failed_login_lock_status` table is implemented in Percona Server for MySQL 8.0.44-35 and exposes information about temporary account locking from MySQL internal Access Control List (ACL) cache.

This table is read-only, and global, per-database or per-table `SELECT` privilege on this table are required from users who want to access the table contents.

| Column Name | Data Type | Description |
|--------------------------|---------------------|------------------------------------------------------------------------------------------------------------------------------------------------|
| `USER` | `CHAR(..)` | Identifies the user account described by the table row |
| `HOST` | `CHAR(..)` | Identifies the user account described by the table row |
| `IS_TRACKING_ACTIVE` | `enum('YES','NO')` | Indicates whether failed login tracking is enabled for the account |
| `MAX_ATTEMPTS` | `INTEGER` | Maximum number of failed login attempts allowed before account is locked (corresponds to FAILED_LOGIN_ATTEMPTS clause value in CREATE USER statement) |
| `PASSWORD_LOCK_DAYS` | `INTEGER` | Number of days for which account will be temporarily locked after exceeding the MAX_ATTEMPS limit. Set to -1 if account is locked forever (corresponds to PASSWORD_LOCK_TIME clause value in CREATE USER) |
| `IS_LOCKED` | `BOOLEAN` | Indicates if account is temporarily locked by failed login lock tracking. NULL if tracking is not enabled for account |
| `REMAINING_ATTEMPTS` | `INTEGER` | Number of failed login attempts remaining before account will be locked. NULL if tracking is not enabled for account |
| `REMAINING_DAYS_LOCKED` | `INTEGER` | Number of days for which account is locked due to failed login lock tracking. -1 means that account is locked "forever" (until server restart/FLUSH PRIVILEGES or specific account unlock). NULL if tracking is not enabled for account |
