# gp_configuration_history

The `gp_configuration_history` table in the `pg_catalog` schema contains information about system changes related to fault detection and recovery operations. The `fts_probe` process logs data to this table, as do certain related management utilities such as `gprecoverseg` and `gpinitsystem`. For example, when you add a new segment and mirror segment to the system, records for these events are logged to `gp_configuration_history`.

The event descriptions stored in this table may be helpful for troubleshooting serious system issues.

This table is populated only on the coordinator. This table is defined in the `pg_global` tablespace, meaning it is globally shared across all databases in the system.
