Redis/ElastiCache

OpsVerse's Kubernetes agent can be used to collect metrics from Redis/ElastiCache.
Kubernetes
Add the following YAML snippet to the agent's values.yaml and run the agent based on these instructions.
YAML
redis-exporter:
  enabled: true
  annotations:
    prometheus.io/scrape: "true"
  redisAddress: redis://<redis-host>:<redis-port>

  service:
    type: ClusterIP
    port: 9121
    annotations: {}
    labels: {}

      # prometheus.io/scrape: "true"
  redisAddressConfig:
    # Use config from configmap
    enabled: false

    # Use password authentication

Refer values.yaml file from Prometheus community for additional value configurations and default values.
Scrape Multiple Redis Hosts
Add the following YAML snippet to the property victoria-metrics-agent.config.scrape_configs in your values.yaml and run the agent based on these instructions.
YAML
extraScrapeConfigs:
  ## config for the multiple Redis targets that the exporter will scrape
  - job_name: 'redis_exporter_targets'
    static_configs:
      - targets:
        - redis://first-redis-host:6379
        - redis://second-redis-host:6379

Single Machine
Alternatively, you can install the Prometheus Redis exporter on a single machine.
Prerequisite(s):
you have the OpsVerse Agent running on the machine.
Run this command to install the Redis exporter as a systemd unit:
Shell
# For amd64
curl https://raw.githubusercontent.com/OpsVerseIO/installers/main/prometheus-exporters/install-exporter-amd64.sh | sudo bash -s -- -e redis

# For arm64
curl https://raw.githubusercontent.com/OpsVerseIO/installers/main/prometheus-exporters/install-exporter-arm64.sh | sudo bash -s -- -e redis
# For amd64
curl https://raw.githubusercontent.com/OpsVerseIO/installers/main/prometheus-exporters/install-exporter-amd64.sh | sudo bash -s -- -e redis

# For arm64
curl https://raw.githubusercontent.com/OpsVerseIO/installers/main/prometheus-exporters/install-exporter-arm64.sh | sudo bash -s -- -e redis
﻿
The agent will begin scraping the metrics automatically; the script will drop the scrape target into /etc/opsverse/targets/, so the agent will begin automatically scraping
If you need to update Redis connection info, after you install, you may edit /etc/systemd/system/prom-redis-exporter.service with the appropriate CLI args you want, and then restart the service:
Shell
sudo systemctl restart prom-redis-exporter

sudo systemctl restart prom-redis-exporter
