Modern-day applications are becoming more complex due to migration from a monolith architecture to microservices or applications using different languages, frameworks, serverless functions, and cloud or on-prem environments. To stay competitive, organizations are going for faster development and deployment cycles. Because of the complexity and variety of data sources, it’s now difficult to understand the root cause of problems. Application Performance Monitoring or Application Performance Management (APM) helps organizations collect, process, and visualize telemetry data from different systems and quickly find the root cause of issues.

There are many open-source and vendor-provided APM tools. Below are some of the vendor-provided APM tools.

Here are the vendors we cover (this is not an exhaustive list!):

It also identifies resource optimization opportunities in the environment.

Key features of Splunk APM:

  • Splunk APM collects all traces instead of the sampled set, which helps not leave any anomaly undetected.
  • It provides immediate feedback on any release.
  • Dynamically generated service maps provide visibility to all service interactions, inferred services, dependencies, and performance.
  • Correlates events in latency or errors with tag values, providing one place to understand how traces behave across the system.
  • Provides visualizations that help developers understand how their microservices impact all their workflows.
  • Important business transactions can be tracked by grouping traces based on a common service or tag.
  • Provides smart dynamic alerting.
  • Provides code-level performance analysis to troubleshoot bottlenecks and optimize performance in cloud-native and monolith applications.

Dynatrace provides an APM that supports multiple languages, application architectures, cloud, on-premises or hybrid, enterprise applications, SaaS monitoring, etc. It provides real-time visibility into microservice-based environments and automatically discovers and monitors microservice workloads running inside containers on Kubernetes. It also provides monolith and mainframe monitoring, database monitoring, application monitoring, and many other services for end-to-end visibility.

Key features of Dynatrace APM:

  • Provides all relationships and dependencies across all components in the system.
  • Automatically monitors cloud-native workloads and microservices.
  • Provides complete visibility into microservice communication.
  • Improves production quality with code-level tracing.
  • Provides the ability to push new code to production faster and with higher quality.
  • Identifies database issues that impact application performance.
  • It automatically discovers and monitors all message queues, enabling teams to detect underperforming services and proactively act before it impacts users.

Azure Application Insights

Microsoft's Application Insights is an Azure Monitor feature that provides APM-like tooling for web applications, with agents and/or SDKs for .NET, .NET Core, Java, Node.js, and JavaScript, and distributed tracing (supports OpenTelemetry). Tracing information is automatically collected by SDK dependency auto collectors for popular frameworks, libraries, and technologies.

Key features of Azure Application Insights:

  • Automatically detects performance anomalies.
  • Provides visibility into user interactions with applications by logging different metrics.
  • Powerful analytics tools.
  • Can be used for applications hosted on-premises, cloud, and hybrid environments.
  • Monitors and analyzes telemetry data such as logs, metrics, and traces collected from mobile apps.

Who is the best APM provider for you?

With the onslaught of new vendors and features to consider, how do you vet and choose the right APM vendor for you? Below, we break down how some vendors fit in with common APM and observability use cases.

Complex Enterprise Hybrid Environment

Need to monitor a complex hybrid environment (or even exclusively on-premises)? Maybe you also expect a sales cycle and customer support package best-suited for enterprise. In such cases, your best options are:

  1. Dynatrace
  2. AppDynamics

Dynatrace is better if you also have lots of microservices or serverless running your applications, whereas AppDynamics might have more powerful tools for understanding the end-to-end user journey.

Cloud-native Technology Company

If you are a cloud-native technology company that has scaled-up or are scaling up rapidly (e.g., a "unicorn"), the simple answer is to go with Datadog nearly every time. You might want to consider other options if you are sensitive to cost.

Small Business and Budget

SolarWinds APM does not offer nearly the amount of features as other APMs, but it does offer a very simple and affordable pricing structure that is suitable for small environments. Alternatively, New Relic is also free if you keep the amount of data ingested per month to under 100 GB.

AWS Native Monitoring

Amazon CloudWatch usually does the trick if you don't have any (or very little) 3rd party services or other cloud providers in the mix.
