RedisDB

Overview

The Redis integration with Motadata AIOps captures health, performance, memory, persistence, replication, and keyspace KPIs from Redis servers. Metrics are grouped by subsystem for clearer monitoring and alerting.

Prerequisites

Ensure the following before onboarding Redis:

• Redis server is reachable over the network.
• The Redis INFO command (or equivalent API/exporter) is enabled for the monitoring user.
• Required credentials/allowlist are configured (if requirepass/ACLs are used).
• The device is discovered in AIOps using the supported protocol/collector.
