Updated: February 4, 2026

Overview

Outlines the principles, architecture, and procedures for achieving high availability and disaster recovery with Cisco IoT FND and Postgres, including system prerequisites, configuration tasks, migration steps, server monitoring, troubleshooting, and reference information for deployment and maintenance.

    HA and DR for Cisco IoT FND with Postgres

    Use this topic to understand high availability (HA) and disaster recovery (DR) options for Cisco IoT Field Network Director (FND) when using a Postgres database.

    Prerequisites

    This topic outlines the prerequisites for implementing high availability (HA) and disaster recovery (DR) for Cisco IoT Field Network Director (FND) with a Postgres database.

    Restrictions

    This topic describes the limitations and restrictions that apply when implementing high availability (HA) and disaster recovery (DR) for Cisco IoT Field Network Director (FND) with a Postgres database.

    HA and DR architecture

    This topic explains the architecture for Cisco IoT FND that employs a distributed multi-site deployment using EnterpriseDB Standard Postgres with the Postgres Distributed (PGD) solution. This design ensures continuous operation by utilizing two active FND application servers across separate data centers, automated database failover via co-located PGD Proxies, and DNS-based traffic routing, providing enterprise-grade resilience and data protection.

    Configure HA and DR

    Use this topic to configure and implement high availability for Cisco IoT FND using PostgreSQL, ensuring continuous service and minimal downtime.

    Database and Cisco IoT FND Migration

    This topic contains all the migration related information to achieve HA and DR on Cisco IoT FND with Postgres.

    Monitor servers

    Learn how to monitor HA databases and nodes using Cisco IoT FND. This procedure explains how to access the server inventory and interpret key status fields such as connectivity, IP addresses, and open issues to ensure the health of your network infrastructure.

    Configure self-signed certificates

    Use this procedure to configure self-signed certificates for high availability AppServer communications in Cisco IoT FND. This setting allows the application to use self-signed certificates instead of default custom certificates to facilitate secure communication between HA server nodes.

    Example Influx DB to Postgres migration log

    This topic contains an example logs from Influx DB to Postgres migration process.

    Troubleshoot stale server entries

    Use this procedure to troubleshoot stale server entries in Cisco IoT FND following a migration from InfluxDB to Postgres. Learn how to identify and remove outdated server records displayed with a "DOWN" status to ensure your device inventory remains accurate and up to date.

    Troubleshoot CPU and memory issues

    Use this topic to troubleshoot CPU and Memory issues while setting up HA on Cisco IoT FND with Postgres
