# HA/DR Monitoring

SAP Adaptive Server Enterprise (ASE) High Availability and Disaster Recovery (HADR) system involves two ASE servers, one serving as the primary for transaction processing and the other as a standby with replicated databases.

For monitoring this setup, IT-Conductor's ASE HA/DR monitoring feature provides visibility into the primary and standby servers, along with the status of the HADR system, synchronization mode, and synchronization state.

In the event of a primary server failure and the promotion of the standby server to the primary role, IT-Conductor quickly identifies the new active primary server.

The servers are visually organized in a cluster grouping, distinguishing the standby server with an inactive status symbol, typically represented by a power icon. This enables teams to promptly identify the current state of the system and take necessary actions to ensure uninterrupted service.

### Prerequisites

[Configure ASE primary and secondary databases for monitoring](https://docs.itconductor.com/user-guide/monitoring/database/sap-ase) before configuring HA/DR monitoring in IT-Conductor.
