MySQL metrics
🐬
Rows add up.
The MySQL group of the metrics tab shows the database space an environment uses. It appears with the MySQL component.
MySQL storage
The space the database of the environment uses. A sample holds the size at that moment. A bar shows four values from its samples:
- max: the largest size of the hour or day
- last: the size at the end of the hour or day
- avg: the average size
- min: the smallest size
The lines mark the storage of each MySQL plan. See why MySQL storage grows and autoscaling.
