Best Redis Monitoring Tools

Redis stands for Remote Dictionary Server and is a fast-growing NoSQL database system that stores all of its data in the server’s memory. The system does maintain a data file, but this is entirely loaded into memory on startup. The system will also write out to the file from time to time during normal operations.

So, there are two critical server resources that you already know need to be tracked closely in order to ensure that Redis keeps running smoothly: memory and disk space. Another tricky feature is that it runs a process that operates as a server and then forks a new process to deal with each request. That system slots processor capacity up in the list above disk space to become the second most important server resource to monitor for Redis.

Here is our list of the best Redis monitoring tools:

  2. SolarWinds Database Performance Monitor (FREE TRIAL) A focused cloud-based system for monitoring a range of database management systems, including Redis. Install a 14-day free trial.
  3. Site24x7 Infrastructure (FREE TRIAL) A flexible cloud-based monitoring package that will give you views on server resource usage and Redis monitoring from a special integration. Access a 30-day free trial.
  4. Sematext Redis Monitoring This service watches over Redis and other database types, while also tracking the performance of other applications, plus networks and servers. Available as a SaaS package or a virtual appliance.
  5. Datadog A cloud-based monitoring platform that includes an extension for monitoring Redis databases.
  6. ManageEngine Applications Manager An on-premises package that examines the Redis database, its host, and the applications that connect to it. It is available for Windows Server and Linux.

Although the database handles process termination well, there is always a risk with subordinate processes that some are going to be left abandoned but still officially available. This clogs up your processor with unwanted processes – a factor that needs to be identified and dealt with.

All of the major cloud platforms offer Redis hosting services, so there is the possibility that you need to manage a cloud-based Redis implementation. Even if you don’t have a cloud Redis implementation right now, there is no reason to rule that option out when choosing a monitoring system for Redis.

Requirements for a Redis monitoring tool

We have already identified some fundamental requirements for a Redis monitoring tool

  • Memory monitoring
  • Process monitoring
  • Disk monitoring
  • On-premises and cloud monitoring capabilities

As it is very possible that you might end up managing Redis instances both on your server and on a cloud platform, it would be nice to have a Redis monitoring tool that can supervise both of these environments and unify monitoring in one screen to reduce the need for switching between live monitoring dashboard pages.

Another great enhancement to aid your Redis management strategy would be a monitor that could identify those services and applications that use Redis databases and watch their interactions. By this method, together with server resource monitoring, you get monitoring services above and below your Redis implementations.

Add a requirement for a monitoring tool that can look inside the system and identify the efficiency of operations, and you will have a complete Redis monitoring tool.

Efficient Redis monitoring

There are a number of ways that the wrong monitoring tool can cost you time, effort, and money. The biggest is if it is only able to perform monitoring for Redis. Although Redis is becoming increasingly important, it is never going to become the pivotal application for your organization. You have plenty of other applications to worry about – including other database management systems.

You don’t want to get a standalone Redis monitoring system because then you will have to waste time switching to a different console every time you want to check everything is OK. If you end up with a Redis monitor that charges per seat, then you will probably only authorize one user account to access the console. That makes tracking access to the account harder and will end up reducing the strength of your security monitoring strategy by making it impossible to identify which technician was on the Redis monitor and when.

This means that your best option for a Redis monitor is one that is integrated into other monitoring services and gives you a range of functions, allowing you to supervise many different resources and applications from one location.

A Redis monitor that has an integrated alerting system would be a great time saver. Systems that institute performance thresholds really reduce your operating expenses. These tools watch over the Redis database unsupervised. Such a monitor usually also issues an alert if performance fails a test. It should be possible to set up the system so that it forwards those alerts to a member of staff by email or SMS.

Alerting systems effectively automate your Redis monitoring tasks because you can put staff onto other tasks, knowing that someone will be called back to the monitor’s dashboard if a problem is detected. It is smart to set those alert thresholds low enough so that they buy you time to fix problems but high enough so that you aren’t pestered by notifications all the time. Some monitoring services even work out the ideal level for performance thresholds through AI-based machine learning – that’s a great time saver.

The Best Redis Monitoring Tools

There are many Redis monitoring tools available at the moment and investigating all of them will take up a lot of your time. Fortunately, this guide will cut down your candidate selection time by narrowing down your search to those monitoring tools that we have identified as the best.

Our methodology for selecting a Redis monitoring system

We reviewed the market for Redis monitoring tools and analyzed the options based on the following criteria:

  • NoSQL activity tracking capabilities
  • Identification of supporting resources
  • Correlation between data access events and resource usage
  • Identification of orphaned processes
  • Resource lock identification
  • A free trial or a demo system that offers an opportunity for assessment before paying
  • Value for money that is provided by an effective monitoring system offered at a fair price

Using this set of criteria, we looked for Redis monitoring tools that give an efficient and comprehensive tracking service for the complicated field of NoSQL.

You can read more about each of these options in the following sections.

  • Uptime in hours
  • The latest average memory usage
  • Current connections count

The graphs shown in the screen convey the following statistics over time:

  • Current connections
  • Total connections received
  • Blocked clients
  • Total commands processed
  • Used memory
  • Changes since last save
  • Expired keys

Any of those graphs can be expanded. It is also possible to create your own custom screens by selecting elements to group together.

What makes AppOptics a particularly powerful monitoring system for Redis is that it also has a comprehensive battery of server resource monitoring modules. These include the tracking of those important server resources that keep Redis running, such as CPU utilization, memory usage and availability, disk operations, and disk capacity.

This Redis monitoring tool isn’t limited to monitoring on-premises implementations. It can also monitor AWS Elasticache and also Azure services. In all locations, monitoring services include performance thresholds and alerts. The system presents an infrastructure overview that highlights potential problems. Drill down on that highlighted area to get greater detail of exactly which element is in difficulty.

Who is it recommended for?

The AppOptics Infrastructure Monitoring service is very affordable and it doesn’t incur the cost of server space to host it. The system can be extended by moving up to the APM plan, which will show you the source of demand on your databases from Web applications.

4. Sematext Redis Monitoring

Sematext Redis Monitoring

Sematext Redis Monitoring is part of Sematext Infrastructure Monitoring, which provides full-stack observability, covering networks, servers, and applications. By simultaneously monitoring all elements of infrastructure, the Sematext service can identify the exact cause of performance problems when they arise. So, if your Redis implementation is at fault, you will know straight away.

Key Features:

  • Redis Performance Monitoring: Searches log data for source data
  • Related Application Tracking: Links issues arising in dependent systems
  • Infrastructure Monitoring: Measures server resource available

Why do we recommend it?

Sematext Redis Monitoring is a free add-on to the cloud-based Infrastructure Monitoring plan. The package simultaneously tracks the performance of all your other IT assets and that lets you see whether a delivery problem is caused by your Redis databases or is rooted in a problem elsewhere.

Redis is notable for operating all of its activities within memory. So, the availability of memory is vital when keeping an eye on the availability of the database system. Redis needs space to hold data in cache and also RAM to assemble and retrieve pertinent data. So, Sematext will raise an alert if it senses that Redis is running out of space.

Disk capacity is not as important while a Redis instance is live. However,  you need to be sure that there is enough storage space available for Redis to write the database to disk when it powers down. Sematext will watch over disk space as well. There are many implementations of Redis hosted on cloud platforms and the Sematext system can track the availability of resources on AWS, GCP, and Azure. It is also able to monitor on-premises systems and check on connectivity issues on your network and across the internet.

You don’t have to watch the Sematext console all the time because the service will send you a notification by email, Slack message, or Webhooks if a performance issue arises. You get live statistics on Redis and its related applications and services in the console. Sematext will also store metrics for historical analysis – retention time is one of the key elements that decide the price that you pay for the service.

Who is it recommended for?

The Sematext tool is appealing to small businesses because it is available in a free edition. This plan will cover five hosts and there is no charge for the extras that you add on with integrations. The tool is hosted so you can get your system monitor for no cost.

Pros:

  • Memory Monitoring: A key resource for Redis databases
  • Simultaneously Monitors Multiple Applications: Includes monitoring services to track the performance of other database types
  • Connectivity and Availability Monitoring: Alerts for performance problems or resource shortages

Cons:

  • Be Careful with the Retention Period that you Choose: This influences the price of the monitoring package

The ability of Sematext to track all applications running on all of your platforms means that it is able to check on services that will compete with Redis for resources. This is useful for predicting whether memory is going to run out. Sometimes with Redis, the cause of its performance issues is due to server strain from unrelated applications.

Sematext Infrastructure Monitoring is a SaaS package but you can opt to download the software and host it yourself as a virtual appliance over Docker. The lowest edition is called Basic and it is free to use. The data retention period of your plan is the biggest influence on the price you pay – the free edition only holds data for 30 minutes. You can get a 14-day free trial of an unlimited plan.

5. Datadog Infrastructure

Datadog Infrastructure

Datadog Infrastructure is one of the plans offered by the Datadog monitoring platform. This system is delivered from the cloud. The plan is intended to supervise all of the services that support user-facing software, whether they are office software systems delivered over the network or Web services and websites made available over the internet.

Key Features:

  • SaaS Package: Can be extended by a library of integrations
  • Integration for Redis Monitoring: Also supporting resources
  • Monitors Multiple Redis Instances Simultaneously: Also correlates with the performance of related applications and services

Why do we recommend it?

Datadog Infrastructure is a module on the Datadog cloud platform. This package will monitor all of the services that lie between user-facing software and your servers or cloud platforms – it includes server resource monitoring. The tool can be expanded by interactions and there is one for Redis monitoring.

The most important feature of Datadog Infrastructure is its library of integrations. If Datadog loaded all of its capabilities into the Infrastructure package out-of-the-box, the dashboard would be immense. There are more than 500 integrations available.

By activating the Redis integration, you will add extra screens to the dashboard and the system sends out probes to the hosts of your Redis instances. As well as a Redis plugin, you will find an integration for AWS ElastiCache and Azure Redis Cache. So, you can monitor Redis databases on the cloud as well.

Datadog is able to collect a large number of different statistics that illuminate database performance. These include four memory-related metrics, four activity statistics, two persistence indicators, and three error-related statistics. You can decide which of these factors are displayed in the dashboard – you don’t have to watch all of them.

You can customize the screens in the Datadog dashboard, which will also examine the interaction between the Redis database and server resources. It will track host resource availability for all of the processes on the same server, so you can see whether resources are running out and which applications to kill or move in order to make space.

Who is it recommended for?

You would get the most out of the Infrastructure plan if you add on linked monitoring packages, such as Network Performance Monitoring and Network Device Monitoring because that will let you see whether your user-reported problems are caused by your Redis database or some other element of your delivery system.

Pros:

  • Highly Customizable Dashboards: Choose the source and format for each metric that you would like to see
  • Cloud Hosted: Access the dashboard through any standard Web browser
  • Other Options: 400+ integrations

Cons:

  • No On-Premises Version: Only available as a SaaS platform

You will get an alert when performance drops or resources reach a point of exhaustion. The highest plan of Datadog Infrastructure includes machine learning processes to automatically adjust performance thresholds to reduce false alarms. Alerts can be forwarded to members of staff by email or SMS. The higher plan, which is called Enterprise, also includes an automatically created application dependency map. That speeds up root cause analysis when problems arise.

The base plan of Datadog Infrastructure is called Pro and there is also a Free edition, which is limited to monitoring one host. You can get a 14-day free trial of the Pro and Enterprise editions.

6. ManageEngine Applications Manager

ManageEngine Applications Manager

ManageEngine Applications Manager gives you a very wide view of how your Redis databases fit into your entire system. The service tracks all applications and all server resources and it creates a map that shows how everything fits together. The automatic application dependency map is constantly updated and it shows all of the systems that access your Redis databases and all of the resources that the database relies on.

Key Features:

  • Performance Alerts: Can be forwarded as notifications by Slack, SMS, or PagerDuty
  • Notify a Technical Support Team: Automatically converts alerts into tickets in ManageEngine ServiceDesk Plus
  • Server Resource Monitoring: Ensures that sufficient memory and CPU are available for running Redis processes

Why do we recommend it?

ManageEngine Applications Manager is a package that provides monitoring for applications, services, and servers. The tool discovers all of your applications and creates an application dependency map. It is able to monitor Redis databases, so you will get performance reports for your database in the context of its related services.

The Applications Manager tracks a range of memory statuses as part of its Redis monitoring service. It looks at specific Redis-driven memory events as well as system-wide memory statuses. The monitor also looks at network interactions by the Redis database. This is a very relevant factor with Redis because it is a clear indicator of successful interaction with client applications.

Dataset persistence is a matter of interacting with the storage file that backs up the database and reloads it into memory after a system crash. Applications Manager checks on persistence factors and also checks on the health of the storage file.

Applications Manager, with its performance thresholds and alerts, is a very suitable complete system monitor for teams that are stretched and expected to multi-task. Alerts can be sent out as notifications by email or SMS. The prepared application dependency map is there to speed up root cause analysis.

Who is it recommended for?

This package is tempting for businesses of all sizes. There is a Free edition, but it is limited to tracking five assets. However,r it will monitor a Redis database. The Professional edition’s base price is accessible and suitable for small businesses. Pay a higher price for more monitoring capacity.

Pros:

  • On-Premise and Cloud Deployment Options: Delivered as a software package in all cases
  • Application Discovery: Creates a dependency map
  • Log Monitoring for Redis: Captures metrics such as memory usage, disk IO, and cache status

Cons:

  • No SaaS Option: Install the software on your Windows server or Linux host or on your AWS or Azure account

The software for Applications Manager installs on Windows Server or Linux. It is available in three editions: Free, Professional, and Enterprise. The Free edition will only run five monitors. The Professional version can monitor one site and the Enterprise edition is designed for large, multi-site businesses. You can try Applications Manager on a 30-day free trial.

Redis Monitoring FAQs

What is Redis monitoring?

The NoSQL database system, Redis holds a lot of data in memory, so Redis monitoring needs to focus on memory management. If the Redis service doesn’t have enough memory available, the whole system will seize up because memory is also needed for tasks such as sorting and filtering. A memory shortage would cause the Redis system to hang, while functions wait for memory to become available in order to execute. Fortunately, it is possible to record total memory availability and track memory usage to spot approaching resource exhaustion.

How do I monitor my Redis queue?

The easiest way to monitor the Redis queue is to get a database or server monitoring tool that has an integration for Redis. “Integrations” are extensions to standard system monitoring packages that add on capabilities to gather data from specific technologies. In many cases, these integrations also add on extra pages to the monitoring dashboard to display the gathered data and implement alerts to draw attention to reducing spare capacity. An alternative method is to gather logs and set up your own search strings to look for specific messages about the queue. The creation of a manual queue monitoring service is time-consuming, so buying a pre-written monitor is worth the money.

Is Redis a cache or DB?

Redis is a directory service, that provides structured data management. The specification for Redis provides message brokers to define different record structures and confirm data integrity. Another major feature of the system is a queue structure. All of these attributes mean that Redis can be used to cache data or to formally structure records into a database. By keeping data in memory, Redis can deliver recently processed records very quickly, which gives it an advantage as a short-term data storage and serving system.
