Why use a Redis monitoring tool?

Redis is a bit different from other database structures like MySQL and does not rely on tables to store data. Instead, Redis stored data in memory, making it extremely fast when compared to traditional databases that are limited based on the hard disk read and write speeds.

While there are some built-in monitor debug commands you can use, you’ll find that commands like MONITOR are limited in their scope. Commands such as AUTH, EXEC, and HELLO are not logged. Using debug commands like MONITOR also takes a toll on your memory consumption since all the commands MONITOR uses are streamed back on the database.

The tools below will allow you to not only monitor memory and performance metrics across your Redis database, but also centralize your performance monitoring efforts, and take into account variables like the infrastructure as well as the network.

The best Redis Monitoring Tools

1. SolarWinds Database Performance Analyzer – FREE TRIAL

SolarWinds Server Application Monitor

SolarWinds Database Performance Analyzer (DPA) is a cloud-based SaaS tool that can monitor database health and monitor performance across multiple different types of databases including Redis. The platform leverages simple integrations to visualize performance metrics in your database. This is a nice touch considering many of the free and built-in tools are all command line-based. Monitoring is configured to measure every query down to a microsecond giving you a precise look at exactly how your database is performing, and where bottlenecks start to form.

There are a number of pre-configured metrics that the platform tracks, such as top queries, memory allocation, and most popular services. DPM is enterprise-friendly and can measure and collect up to 10000 metrics per second, ensuring no problem slips through the cracks.

Monitoring occurs in both real-time and can be stored in log form for historical audits, or cross-correlations. DPM makes correlating code and queries over time easily, with a built-in section dedicated to comparing instances of the database over time.

Out of the box, DPM can start monitoring and provide insights right away. Adaptive fault detection helps DBAs as well as DevOps work in tune together to pinpoint performance problems, share data, and get the database back up and running optimally.

Rather than using memory to run the queries, DPM installs directly on the server and only uses less than 1% of the CPU to perform its monitoring functions. As a SaaS tool, you won’t have to deal with lengthy onboarding processes, patching, or upgrades.

You can test out SolarWinds Database Performance Analyzer through a 30-day free trial.

Key Features

  • Built-in correlation tool
  • Built for cross-collaboration with DevOps and DBAs
  • Cloud-based tool

2. AppOptics – FREE TRIAL

SolarWinds AppOptics

AppOptics is a monitoring platform that allows sysadmins to monitor Redis along with their IT infrastructure and is paired with tools that give developers everything they need to get databases back up and running when things aren't performing as they should be.

A centralized dashboard monitors uptime and other Redis metrics automatically and pulls that data into insights that can be analyzed further. The platform helps take the traditional Redis Info commands and visualize them in a way you or your team can take action on.

Metrics like client connections, CPU usage, memory utilization, and input details are all available both live and as a historical data log. Every metric can be tagged through AppOptic’s intuitive tagging system, which allows you to customize your tags as you see fit. Out of the box AppOptics assigns tags for your server, ports, database, and hostname.

The platform features over 150 different integrations and allows for multiple ways of sending alert notifications over different channels, or API integrations. Pricing for AppOptics is separated into two categories, Infrastructure, and APM. The APM offers automatic service maps, root causes analysis, and distributed tracing.

The Infrastructure package helps give you a high-level overview of the health of the supporting infrastructure by offering visibility into host and container metrics. You can opt for both packages to get the most amount of coverage for $24.99 per month.

3. Datadog

Datadog Network Mapping

Datadog is a cloud-based APM platform that focuses on measuring all aspects of a network to give administrators a clear picture of exactly what is happening on all levels. The platform does an excellent job of providing out-of-the-box reports, dashboards, and alert monitors that need little to no customization before use.

A lightweight agent collects metrics such as commands per second, cache hit rate, memory usage, and latency right away. The dashboard can also record and display insights for specific memory-related events in Redis like the number of evictions, blocked clients, fragmentation ratio, and keyspace.

These metrics are broken down into three categories, performance, memory, and basic activity metrics. The customizable dashboard allows you to rearrange and prioritize any of these metrics, and even save dashboard views for individuals, or specific NOC teams.

You can easily link specific monitors that measure metrics to alert based on a number of interchangeable variables. Templates can be created for each alert, and messages are intelligent by default to help ensure recipients aren’t accidentally spammed with notifications. These alerts can be sent over apps like Jira, Slack, and PagerDuty, or ported over to a custom platform via webhook.

The platform gives DBAs the tools they need to monitor traces live, with no sampling as well as set up proactive alerts that help prevent database issues from creating outages or noticeable decreases in performance for end-users.

Pricing for DataDog APM is broken down into two tiers, starting with the APM tier at $31.00 per month. This tier gives you many of the basic monitoring features you’d need for a Redis database like distributed tracing, auto-retention, and dependency visualizations.

The second tier called APM & Continuous Profiler is $40.00 per month and includes a few more advanced features like performance correlation, automatic code analysis, and multiple profiling types for deeper insights.

You can try DataDog free with a 30-day trial.

Key Features

  • Automatic code analysis
  • Done-for-you dashboards, reports, and alerts
  • Distributed tracing and correlation tools

4. Paessler PRTG

Paessler PRTG Network Monitor Jitter Monitoring

Paessler PRTG offers monitoring across multiple platforms, devices, applications, and infrastructure, marketing itself as a total monitoring solution. The platform is able to monitor many different environments through the use of customized sensors that are tuned to monitor and report back metrics to a single centralized dashboard.

While many sensors are pre-made, you can create custom sensors tailored to your needs based on the exact metrics you wish to monitor. For example, you can create a custom SNMP monitor to measure specific values inside of your Redis database deployment.

As metrics come in they are displayed on a simple yet effective looking dashboard that helps balance out key visualizations alongside scroll logs of live data. Alert templates in PRTG allow for flexible notification options that can trigger based on the condition as well as thresholds that are met. Alert notifications can be sent via email, third-party apps like Slack, or straight to ticketing platforms via API integration.

Each sensor is configured to measure a single metric, so you’ll likely need multiple sensors per database or server. Pricing is based on the number of sensors you have deployed, which makes scaling your monitoring efforts across large enterprises predictable from a pricing perspective.

There are currently five pricing tiers available starting with PRTG 500 that offers 500 sensors across a single server installation for $1750. You can test out PRTG completely free through a free trial. After the trial is over, your subscription will automatically be downgraded to the free version which limits your account to 100 sensors.

Key Features

Rather than having to manually configure integrations in your server, Site24x7 starts with a basic Linux monitoring agent where you simply install the Redis plugin to allow for data collection.

Stats such as rejected connections, keyspace misses, CPU usage, and peak memory usage are automatically calculated and pulled down in an intuitive dashboard that makes seeing your Redis database health easy, and at a glance.

The platform is highly visual, and in addition to dashboard visualizations also features an application topology map. This feature allows you to easily view database architecture, hierarchy, and interdependencies during troubleshooting. The reporting dashboard allows users to view top-level insights such as apdex scores, and then drill down to the code level to debug errors at the method level.

Reports and alerts can be distributed across many different channels including email, SMS, RSS feeds, and even push notifications for both Android and iOS. Alerts can be tied to any number of conditions or thresholds and can help keep teams in the loop when SLAs aren’t met, or memory usage is reaching a critical level.

Root cause analysis also helps assist DevOps and DBAs to identify exactly where a problem is stemming from on the query level. From a proactive standpoint, built-in SLA management can help keep particular metrics prioritized and also serve as a valuable tool for MSPs who wish to monitor Redis environments on behalf of their clients.

Pricing for Site24x7 starts at $35.00 per month when paid annually, and features a host of modular upgrades that allow you to only pay for structural features that you need, rather than upgrading to a prepackaged tier. You can test out Site24x7 on your Redis database free with a 30-day trial.
