Redis

Introduction

Redis is a high-performance, in-memory data store commonly used as a database, cache, and message broker. Monitoring Redis is essential for tracking key performance metrics such as memory usage, latency, keyspace operations, and more.

To monitor Redis efficiently, we can use the OpenTelemetry Redis Receiver, which collects key Redis performance metrics.

Kubernetes 2.0 ConfigMap

Users should update or append the existing ConfigMap named opsramp-workload-metric-user-config by adding application-specific fields. These fields may include authentication credentials, collection frequency, and other relevant configurations.

apiVersion: v1
kind: ConfigMap
metadata:
  name: opsramp-workload-metric-user-config
  namespace: opsramp-agent

    redis:

              operator: ==
