Yellowbrick Row Store (YRS) Alerts

These alerts monitor the internal state of the Yellowbrick row store system. They also provide early warnings and critical alerts when the number of row store commit records, data files, deleted records, or unused files exceeds configured thresholds.

Purpose

These alerts help operators detect and respond to:

• Excessive commit records.
• Rising numbers of data or unused files.
• Accumulation of deleted records.

Each alert is grouped by severity and is linked to a configurable threshold variable. These thresholds can be adjusted at runtime and override any appliance-level GUCs used in previous Yellowbrick deployments.
