Redis Tools: RedisInsight, Redis CLI, Redis Commander

Introduction

Redis is one of the most widely used data stores for caching, session management, message queues, and real-time applications. Managing Redis effectively requires the right tools for visualizing data, profiling performance, and debugging issues. This article covers the essential Redis tools: RedisInsight, the Redis CLI, and web-based administration tools.

Redis CLI

The command-line interface is the most fundamental Redis tool, shipped with every Redis installation:

# Basic commands

redis-cli ping            # Test connection

redis-cli info            # Server info and statistics

redis-cli monitor         # Real-time command monitoring

redis-cli --stat          # Real-time statistics

# Key operations

redis-cli keys "*"        # List all keys (avoid in production!)

redis-cli --scan --pattern "session:*"  # Safe key scanning

redis-cli dbsize          # Number of keys in database

# Value inspection

redis-cli type user:123

redis-cli get user:123

redis-cli hgetall user:123

redis-cli smembers "tags:article:456"

# Performance debugging

redis-cli --bigkeys       # Find largest keys

redis-cli --hotkeys       # Find hottest keys (Redis 7+)

redis-cli slowlog get 10  # Last 10 slow commands

redis-cli --latency       # Connection latency test

redis-cli --rdb /tmp/dump.rdb  # Generate RDB dump

# Cluster mode

redis-cli -c cluster nodes

redis-cli -c cluster info

# With SSL/tls

redis-cli --tls --cacert ca.crt --cert client.crt --key client.key

Pipeline mode for bulk operations:

# Load data from file

cat commands.txt | redis-cli --pipe

# Generate test data with inline scripting

redis-cli --eval script.lua key1 key2 , arg1 arg2

RedisInsight

Redis's official GUI tool for visualization and analysis:

Key features:

• Browser-based key-value explorer with filter and search
• Tree view for structured key navigation
• Memory analysis and optimization recommendations
• Slow log visualization and analysis
• Real-time metrics dashboard (CPU, memory, connections, commands/s)
• CLI built into the GUI
• Pub/Sub message inspector

• Redis Stream management and TRIM operations

  Start RedisInsight

  Download from https://redis.com/redis-enterprise/redis-insight/

  Or run as Docker container

  docker run -d -p 5540:5540 redis/redisinsight:latest

  Access at http://localhost:5540

Workbench for advanced querying:

# RedisInsight Workbench supports:

# - Multi-line queries with Ctrl+Enter

# - Query history with search

# - Result visualization (JSON, Table, Raw)

# - Command autocomplete

# Memory analysis commands

MEMORY DOCTOR          # Get memory optimization suggestions

MEMORY USAGE user:123  # Memory used by a specific key

MEMORY STATS          # Overall memory statistics

# Performance analysis

SLOWLOG GET 20        # Most recent slow commands

CLIENT LIST           # Connected clients and their queries

INFO COMMANDSTATS     # Command execution statistics

Strengths: Official Redis tool, excellent memory analysis and optimization recommendations, professional data visualization, free.

Redis Commander

A web-based Redis management tool built with Node.js:

# Install globally

npm install -g redis-commander

# Start with default settings

redis-commander

# With custom configuration

redis-commander --redis-host redis.example.com --redis-port 6379

redis-commander --redis-password yourpassword

# Docker

docker run -d -p 8081:8081 rediscommander/redis-commander:latest

# Access at http://localhost:8081

// Custom configuration

{

  "redis": {

    "host": "localhost",

    "port": 6379,

    "password": "",

    "db": 0

  },

  "server": {

    "port": 8081,

    "address": "0.0.0.0"

  }

}

Features:

• Tree-based key browser with auto-refresh
• JSON viewer and editor for complex values
• Terminal/CLI panel
• Import/export data in JSON format
• Lightweight and simple UI
• Connection to multiple Redis instances

Redis Monitoring with redis-stat

# Install via gem

gem install redis-stat

# Run monitoring dashboard

redis-stat --server=6379 1  # 1 second refresh interval

# Run on headless server

redis-stat --daemon --server=redis:6379 5

Production Usage

#!/bin/bash

# Redis production health check script

echo "=== Redis Health Check ==="

echo ""

# Connection test

echo "Ping: $(redis-cli ping)"

# Memory usage

MEM=$(redis-cli info memory | grep "used_memory_human" | cut -d: -f2)

MAXMEM=$(redis-cli info memory | grep "maxmemory_human" | cut -d: -f2)

echo "Memory: $MEM / $MAXMEM"

# Key count

KEYS=$(redis-cli dbsize)

echo
