What Is DevOps Monitoring? Types Of Monitoring In DevOps: What Should You Monitor? What Factors To Consider When Choosing A DevOps Monitoring Tool  Top DevOps Monitoring Tools By Category

DevOps emphasizes continuous improvement, rapid delivery, and cost optimization. It does this by recommending several engineering best practices you can implement in your IT environments. 

DevOps also emphasizes automation to improve efficiency and engineering velocity in software delivery. 

In this guide, we will cover the importance of DevOps monitoring. This will include what to monitor and a list of some of the best monitoring tools for DevOps teams.

What Is DevOps Monitoring?

A DevOps monitoring process involves continuously identifying, tracking, analyzing, and reporting on specific components of IT infrastructure. Engineers also refer to DevOps monitoring as Continuous Monitoring (CM) and Continuous Control Monitoring (CCM).

In DevOps, the process follows a continuous pipeline. This pipeline consists of planning, developing, integrating, testing, deploying, and operating phases.

Practicing DevOps can be quite involving, but the benefits justify the effort. Some benefits of DevOps monitoring include:

  • Define, track, and measure actual key performance indicators across all aspects of DevOps. 
  • Increase the observability of various components of your DevOps stack so you can identify when they degrade in performance, security, cost, or other aspects.
  • Detect and report anomalies to the relevant teams quickly so they can resolve issues before they affect the user experience.
  • Analyze logs and metrics to uncover root causes as quickly as possible. Tracking logs and metrics can help pinpoint where an issue started or occurred. As a result, your Mean Time To Detection (MTTD), Mean Time To Isolate (MTTI), Mean Time To Repair (MTTR), and Mean Time To Recovery (MTTR) can improve. 
  • Respond to threats on-call or automatically using a variety of tools.
  • Find opportunities for automation throughout the DevOps process that will improve engineers’ DevOps toolchains and efficiency. 
  • Identify patterns in system behavior that a DevOps engineer should be on the lookout for in the future.
  • Create a continuous feedback loop that improves collaboration among engineers, users (internal and external), and the rest of the organization.

By monitoring DevOps activities, an organization can maintain optimal customer experiences while reducing costs throughout the DevOps lifecycle.

Types Of Monitoring In DevOps: What Should You Monitor?

Continuous monitoring in DevOps comes in four main forms:

  • Infrastructure monitoring 
  • Application monitoring
  • Network monitoring
  • Cost monitoring

Here are brief descriptions of each.

Infrastructure monitoring

Monitoring your DevOps infrastructure involves detecting, tracking, and compiling real-time data on your components’ health and performance. These components include servers (virtual or physical), databases, and middleware. 

There are two types of infrastructure monitoring:

  • In agent-based infrastructure monitoring, engineers install an agent (software) on each of their hosts, either physical or virtual. The agent collects infrastructure metrics and sends them to a monitoring tool for analysis and visualization.  
  • Agentless infrastructure monitoring doesn’t involve installing an agent. Instead, it uses built-in protocols such as SSH, NetFlow, SNMP, and WMI to relay infrastructure component metrics to monitoring tools.

There are advantages and disadvantages to each approach. Monitoring using agents, for example, collects more detailed information because it is tailored to the device or components you wish to monitor. 

On the flip side, if you want to migrate to another platform, the agent may not be compatible with your new platform, resulting in data loss. Plus, the agents can be resource-intensive on your servers causing latencies or additional costs

Several infrastructure components, including VMs (such as Hyper-V and VMware), servers, networking, storage, and flow devices, come with built-in agentless monitoring capabilities. You can also manage these components’ monitoring centrally.  You can combine the two approaches to build a comprehensive monitoring strategy. 

Application (APM) monitoring

This ongoing process involves monitoring an application’s performance and availability, along with the effects the two have on a user’s experience. A monitoring application tracks your app’s hardware utilization, SLA status, platform performance, and user response times. 

Server diagnostics, error logs, network traffic reports, historical statistics, and failure diagnostics are among the metrics DevOps engineers can monitor here.

Network monitoring

Here, engineers use software and hardware to monitor the health and performance of network components, such as switches, servers, and routers. Monitors track bandwidth, uptime, and bottlenecks, such as failed switches.   

By performing periodic checks, monitoring tools can detect failing or failed incidents before they have an impact on user experience. 

Cost monitoring

Tracking costs throughout the DevOps pipeline is essential for avoiding cost overruns. 

Monitoring costs involves identifying resource usage. Besides real-time metrics, some advanced cost intelligence tools can collect exact costs per unit and per customer or project and share them with engineers and finance teams for further action.  

This capability enables you to understand your Cost Of Goods Sold (COGS), gross margins, and resource usage at each phase of DevOps.

What Factors To Consider When Choosing A DevOps Monitoring Tool 

Here’s a quick checklist of some of the crucial considerations to make when selecting monitoring tools for DevOps teams. 

  • All-in-one observability – Rather than having separate views that often lead to visibility gaps, you’ll want a solution that lets you view most components together.
  • User-friendly interface – Select a monitoring tool with customizable dashboards and interactive features to help you tailor the information to your requirements. 
  • Automatic discovery – This automates the process of searching for and identifying IT assets in a network. It saves time and effort. Many monitoring tools offer this, but not all of them do. 
  • Real-time metrics, events, and distributed traces – Real-time analytics uses monitoring data as it becomes available, enabling you to detect errors before they become costly problems.  
  • Root cause analysis – This approach enables you to identify and fix the root cause instead of simply settling symptoms for a while before they return. 
  • Data retention periods – Most DevOps monitoring tools have specific data retention limits. A longer retention period will cost more, but it can help you identify system health patterns, especially when problems occur occasionally.
  • AIOps and Machine Learning – Some DevOps monitoring tools utilize AI technologies to enhance searching, answering, and resolving technical issues, reducing time and improving productivity. 
  • Resource usage and related cost monitoring – Cost is now a first-class metric for most organizations, as 32% of cloud budgets are wasted. Yet, most cost tools are clunky, inexact, and mostly deliver total and average cost — not specifics such as Cost per Customer, Cost per Deployment, or Cost per Request.

With these factors in mind, here are some of the best DevOps monitoring tools to support continuous improvement.

Top DevOps Monitoring Tools By Category

DevOps tools offer several benefits: 

  • A DevOps tool automates repetitive tasks. You can use this to free your engineers up so they can focus on only the most critical tasks, such as patching security threats or releasing advanced features more quickly to boost your organization’s competitiveness.
  • Reduce human error to release reliable code more quickly.
  • Improve the software development process using Continuous Integration and Continuous Development (CI/CD).  
  • Combining these DevOps benefits optimizes costs

Here are some of the top monitoring tools you can use, organized into several DevOps categories.

Open-source DevOps monitoring tools

If you are on a tight budget or want continuous monitoring that you can customize, open-source software may be helpful. Here are four examples: 

1. Nagios

Nagios

A pioneering DevOps monitoring tool, Nagios offers server, application, and network monitoring capabilities. It can track any device with an IP address. It also monitors multiple server services, including POP, SMTP, IMAP, HTTP, and Proxy under Linux and Windows. It enables application monitoring as well, including CPU, swap, memory, and load analysis.

Nagios is a free download, has a simple web interface, and supports over 5,000 server monitoring integrations. The free, open-source version of Nagios is called Nagios Core. The paid version, Nagios XI, monitors infrastructure, applications, networking, services, log files, SNMP, and operating systems. 

2. Prometheus

Prometheus

Prometheus is also downloadable. It comprises several monitoring tools useful in a DevOps culture, such as alerting, saving time series on local disks or memory, and displaying data graphically (with Grafana). It also supports many integrations, libraries, and metrics types. 

Take a look at SysDig if you prefer a managed enterprise Prometheus monitoring service.

3. Zabbix

Zabbix

A top Nagios alternative, Zabbix also monitors real-time network traffic, services, applications, clouds, and servers. You can also run it on-premises or in the cloud. Zabbix 5.4 features improved distributed monitoring, high availability, and support for many types of monitoring metrics, allowing you to scale your monitoring capabilities in a continuously evolving culture like DevOps. 

4. Monit

Monit

If you are looking for a small monitoring solution for Unix systems, Monit can help. In Monit, you can observe daemon processes, especially those that start at system boot from /etc / init /, such as Apache, sshd, SendMail, and MySQL. 

Monit also offers error detection and alerting as well as monitoring for filesystems, directories, and files on the localhost. Also, you can use it to monitor cloud, host, and systems, including various internet protocols (HTTP, SMTP, etc.) and CPU and memory usage, as well as load average.

All-in-One DevOps monitoring tools

Here are some platforms that offer comprehensive DevOps observability and monitoring capabilities. By eliminating the need to operate different tools for different monitoring needs, these single sources of truth minimize costly visibility gaps, complexity, and waste.  

5. Datadog

Datadog

DevOps teams prefer Datadog because it delivers deep observability data with solid root cause analysis. You can use Datadog to collect, analyze, and share system monitoring data across on-premises infrastructure and cloud environments (private, public, hybrid, multi-cloud). This makes Datadog a robust choice for enterprise use. 

The Cloud Monitoring as a Service platform is built on Go architecture and works across cloud providers, including AWS, Azure, and GCP. And if you are considering it for digital experience monitoring, it supports most devices and operating systems. It also helps that Datadog includes a cloud costs management function.

Datadog customers, however, complain that the service is expensive. So, below are a few competitors who are more affordable and capable. Or, visit 15 Datadog alternatives guide if you want a complete comparison of the competition.

You’ll need to install the New Relic agent on your servers or each device you want to monitor. Also, New Relic doesn’t emphasize security and compliance monitoring as this next alternative.

7. Dynatrace

Dynatrace

In addition to end-to-end observability for DevOps, Dynatrace emphasizes IT security with an arsenal of DevSecOps tools. Dynatrace uses intelligent automation to secure cloud-native apps at runtime. This means it integrates security into your CI/CD toolchains. 

With Dynatrace’s Runtime Vulnerability Analytics and Application Protection, you can minimize exposure to zero-day threats. The DevOps team can continuously surface, analyze, and block app attacks, including command injection and SQL injection.

In addition, Dynatrace offers enterprise-level business KPIs monitoring, a platform for custom application development, and real-time topology mapping with context. Yet, Dynatrace may require some time to learn and optimize and its pricing can be complex. 

8. LogicMonitor 

LogicMonitor

LogicMonitor is an agentless, full-stack observability platform for DevOps applications. Similar to other top monitoring tools here, LogicMonitor offers real-time monitoring in most areas, from Infrastructure to website monitoring.

The cloud-based platform also deploys in minutes, scales seamlessly, and supports hybrid observability (cloud-based and on-premises). It also provides deep monitoring for cloud-based, hyper-converged, and on-premises storage systems. 

For companies that need assurance that their remote working strategy is safe, LogicMonitor’s remote and Software-Defined Network Monitoring (SD-WAN) can be a good choice. Plus, LogicMonitor secures your data both in transit and at rest, offers solid role-based access control (RBAC), and applies TLS encryption.

Application, network, and infrastructure monitoring tools

The following tools offer a nearly “all-in-one” solution for continuous monitoring. 

9. Sensu by Sumo Logic

14. Big Panda

Big Panda

BigPanda’s event correlation algorithms automate the process of aggregating, enriching, and correlating alerts from various infrastructures, clouds, and applications. It reduces alert noise by combining different alerts into one, high-level incident. It also sends alerts via pre-defined channels, such as ticketing, collaboration, and reports.

15. Planview Hub (Formerly Tasktop Integration Hub)

Planview Hub

The Planview Hub enables DevOps teams to combine several vital software delivery tools instead of working with them separately. This is great if you want to keep everything, including Git and code quality assurance processes within a single platform.

Planview Hub comes with a ton of pre-built connectors to enable easier and faster no-code integrations. This supports a wide range of integrations to help automate your flows, from your favorite Git-based repository to tools like Jira and Azure DevOps to ServiceNow and Jama.  

Compared to point-to-point integrations offered elsewhere, the Hub uses model-based integration, enabling faster integration setup, fewer mappings, and less time spent on maintaining integrations.

16. Librato (Now part of SolarWinds AppOptics)

Librato

From its inception, Librato was designed to enable scalable and redundant monitoring of time-series data. The first step is to send data to Librato using one of the many turn-key integrations. Or, you can POST directly to your RESTful API.

By creating dashboards, you can display your metrics in charts and filter your data until you identify a specific issue. You also set up alerts for the most important metrics so you are always aware of the service’s health. This can be done via email, chat, or your favorite escalation service.
Librato supports Rails 3.x or Rack, as well as JVM-based applications and other languages. In addition to creating custom charts and workspaces, you can also add one-time events and set threshold-based alerts.

Users can collaborate with multi-user access, PNG chart snapshots, private Spaces links, and integrations with tools like Slack, HipChat, and PagerDuty.

Business service health monitoring tools

Traditionally, DevOps teams have focused on engineering instead of how their activities impact bottom lines. However, DevOps teams are increasingly focusing on monitoring sites, mobile devices, end users, and real users (RUM) thanks to Engineering-Led Optimization. Here are some tools you can use to optimize your efforts.  

17. Akamai mPulse

Akamai mPulse

mPulse collects real-time insights on real user data to map their behavior to your business performance. It collects detailed data across 200 business and performance metrics directly from your users’ browsers. It then drills down to identify the root cause of latencies and revenue losses across all page views.

Expect to collect performance timers, including bandwidth and page load times. You can collect business metrics such as order totals, bounce rate, and conversion rate.

You receive real-time reports about real user activity as soon as the first mPulse beacon arrives. Widgets in your mPulse dashboard show breakdowns by segment, such as bandwidth distribution, page groups, geographical location, and browser type.

If your organization prefers, you can build custom dashboards to organize your data in the way that makes the most sense to it.

18. Sumo Logic

Sumo Logic

Sumo Logic is best known for its SaaS log analytics, business operations, and security monitoring, powered by AI and Machine Learning. It offers OOTB dashboards and AI-powered troubleshooting to help you visualize, analyze, and act on what’s happening in your business processes end-to-end.  

Sumo Logic offers Cloud SIEM and Soar to help protect your data and workloads. Considering IBM estimates that a single data breach can cost as much as $4.5 million to resolve, Sumo Logtic’s emphasis on cloud security is great for most organizations — big or small.

Ultimately, Sumo Logic is a full-stack observability platform with capacity planning and forecasting. Additionally, it scales well compared to some alternatives. By consolidating all data from your infrastructure, applications, business, and end-users into one place, you’ll have a complete picture of your IT infrastructure.

It just isn’t designed for on-premises deployments, unlike alternatives such as Datadog and Sematext.

19. BMC Helix Operations Management 

BMC Helix Operations Management

The Helix Operations Management tool was designed to improve observability within hybrid cloud environments. To achieve this, it combines automation, AIOps, interactive dashboards, log analytics, events management, and user-friendly workflows in one place.

BMC Helix Operations Management is also great for visualizing real-time activity within your containerized applications. Monitoring these activities can help you understand how technical issues are affecting customer satisfaction – and thus your bottom line. 

More importantly, you can use root cause analysis, predictive analytics, and more of its tools to resolve these bottlenecks to protect your business interests. 

DevOps Source code control tools

DevOps is characterized by multiple teams working on code simultaneously to foster rapid and frequent application updates. The continuous improvement results in many code changes. Teams must be able to ensure all engineers are using the same version of source code. Source code control tools help with that. 

20. Git (GitHub, GitLab, and BitBucket)

Git

Many DevOps teams use Git as their source code management platform. Its local branching model, multiple workflows, and staging areas make it a popular alternative to Mercurial, CVS, Helix Core, and Subversion. 

It is installed locally, however. GitHub allows for remote teamwork and distributed source code control in the cloud. Bitbucket and GitLab are both suitable for enterprise use cases. 

Monitoring CI/CD pipelines and configurations

Jenkins, RedHat Ansible, Bamboo, Chef, Puppet, and CircleCI are some of the best CI/CD tools out there. Monitoring the CI/CD pipelines of these tools can increase visibility into your pipeline in all environments, whether it is in development, testing, or production. 

21. AppDynamics 

AppDynamics

There are several tools and methods for getting visibility at the code level. As an example, you can use Jenkins with Prometheus (ingest and store) and Grafana (visualization). Or you can use an end-to-end continuous monitoring solution for your CI/CD pipeline, such as AppDynamics or Splunk.

AppDynamics provides real-time customer and business telemetry, enabling you to monitor infrastructure, services, networks, and applications with multi-cloud support. It also offers visibility into Kubernetes, Docker, and Evolven. It also provides root-cause diagnostics, a pay-per-use pricing model, and hybrid monitoring. 

Test server monitoring

A test monitor evaluates an ongoing test and provides feedback. In addition, test progress monitoring and control involve several techniques and components that ensure the test meets specific benchmarks at every stage. Selenium is an excellent example of a test progress monitoring tool.   

22. Selenium

Selenium

Selenium is an open-source tool for automating web apps for testing. But you can do more with it. Using Selenium WebDriver, for instance, you can automate regression tests and suites using browser-based regression tests that are scalable and distributed across multiple environments.

Selenium Grid provides a central point from which you can distribute and run tests at scale (several machines, various OS/browsers, and many environments). Selenium IDE is the Firefox, Chrome, and Edge add-on that will let you do simple recording and playback of interactions with the browsers.

Selenium alternatives include Ranorex and Test.ai.

Alarm aggregation and incident management

There are several enterprise-grade tools available that can aggregate and cross-analyze data. Even though BigPanda can aggregate data from multiple sources, PageDuty is a suitable solution for DevOps teams who need on-call management, incident response, event management, and operational analytics.

23. PagerDuty

PagerDuty

PageDuty is a dispatching service that also aggregates alarms without creating alert noise. By offering an easy-to-use GUI and well-organized data, it helps show correlations between events. 

It integrates monitoring systems, customer support, API management, and performance management. Since it supports over 550 integrations, you can connect nearly any monitoring tool or log management tool as long as they can start REST calls or send emails. 

The integrations include AppDynamics, Microsoft Teams, AWS, ServiceNow, and Slack, which you might be already using.   

Alternatives to PageDuty include Slack, AlertOps, Splunk On-Call, and ServiceNow IT Service Management. 

Continuous cloud cost optimization for DevOps

While some cost optimization tools offer traditional cost reporting, more advanced cloud cost intelligence platforms provide rich insights into the context of your business — like CloudZero. 

24. CloudZero

CloudZero

CloudZero is different from most cloud cost optimization tools for several reasons. First, it acts more like an observability platform than a mere cost tool with its robust cost data normalization for IaaS, PaaS, and SaaS. 

CloudZero also doesn’t rely on perfect tags like most tools do. Instead, it intelligently combines your tagged, untagged, and untaggable cost data and transforms it into immediately actionable cost intelligence (unit cost). This includes granular cost insights such as Cost per Customer, per Feature, per Team, per Project, per Environment, per Service, and more.

CloudZero

CloudZero is the only multi-cloud cost optimization platform that offers per-unit cost views across all areas — reported hourly (not once daily or every couple of hours like most cost tools).

In addition, CloudZero empowers you to:

  • Use Engineering-Led Optimization; provide your engineers with insights such as Cost per Deployment, per Service, and per Environment, so they can see how their technical activities impact your bottom line, helping them build cost-effective solutions.
  • Allocate 100% of your cloud spend no matter how complex your environment is.
  • Take advantage of real-time cost allocation to gain cost intelligence as soon as possible to prevent budget overruns.
  • Leverage real-time cost anomaly detection to get timely, noise-free, and context-rich alerts so you can fix issues before they lead to overspending.
  • Use industry-leading Kubernetes cost analysis to understand, control, and optimize both your containerized and non-containerized costs in a single place.
  • Set custom budgets, automatically track them (with threshold-based alerts), and gain accurate forecasting data to inform your cloud strategy.
  • Get a complete picture of your cloud costs in a single source of truth; CloudZero works across AWS, Azure, GCP, and Oracle Cloud as well as Snowlfkae, Kubernetes, Databricks, MongoDB, New Relic, Datadog, and more.

CloudZero has helped ambitious companies such as Drift, Demandbase, and NinjaCat to save over $3 million, 36%, and 40% of their annual cloud costs in record time. Others like MalwareBytes, Remitly, and Obsidian now spend 6-10 fewer hours managing their cloud costs with CloudZero. You can, too.
