Flopsar – How to Choose an APM System

Learn how to choose an APM class system with Flopsar. Discover key features and selection criteria for an application performance monitoring tool that will help ensure the reliability and efficiency of your IT systems.

Another challenge facing IT department heads, if they decide to purchase a tool for managing IT system performance and quality (APM), is choosing the right tool. It should be optimal, i.e., tailored to the specifics of the given enterprise.

So what criteria should we consider when deciding to purchase?

The main criterion should be the licensing method. If the enterprise has many (50+) application servers, per-server licensing will be problematic. What if the number of servers increases to 75 in 12 months? Will we have to “buy additional licenses” again?

Application Performance Manager – Monitor Application Performance

Flopsar has the most flexible licensing model among all APM manufacturers. Perpetual and time-limited licenses are available. Per server, but also per application, or per enterprise without server limits.

Software Features That Distinguish It from the Competition:

  • Easy full configuration capability (without costly training)

  • Load (typically should be a maximum of 2%)

  • Central configuration registry (no configuration files at agents, reducing administrator involvement in maintaining the tool)

  • Reporting of every transaction (by transaction we mean every operation that the application server performs – to find every problem, even for a single user)

  • Reporting of every exception

  • Linear database scalability – no performance problems related to infrastructure with a large number of agents and no need to install commercial databases (e.g., Oracle)

  • Minimal learning curve. In case an employee responsible for monitoring leaves – no problem with onboarding a successor.

  • Low tool maintenance cost (people + infrastructure)

  • DevOps support – the tool must be understandable for developers/testers/administrators/managers

  • Strong manufacturer support

Why this matters for organizations

Learn how to choose an APM class system with Flopsar. Discover key features and selection criteria for an application performance monitoring tool that will help ensure the reliability and efficiency of your IT systems. In the context of growing cyber threats and tightening regulations (NIS2, DORA), organizations must proactively manage this security area. Failure to implement adequate safeguards can lead to data breaches, financial penalties, and reputational damage.

Best practices for implementation

Effective implementation requires several key steps:

  1. Risk assessment and inventory — identify assets, threats, and vulnerabilities specific to your organization.
  2. Policy development — document requirements, roles, and responsibilities.
  3. Technical controls — deploy tools and configurations proportionate to identified risks.
  4. Training and awareness — engage employees in protecting organizational security.
  5. Monitoring and continuous improvement — regularly verify effectiveness and adapt to the evolving threat landscape.

Frequently asked questions

What are the most important criteria for choosing an APM system?

The most important criteria include the licensing model, support for the specific technologies and platforms in use, the depth of diagnostics provided, ease of integration with existing monitoring infrastructure, and total cost of ownership as the environment scales. Organizations with many application servers should pay particular attention to per-server versus flat-rate licensing, as per-server models can become very expensive as the infrastructure grows.

Why is the licensing model such a critical factor when selecting an APM tool?

Per-server APM licensing can become prohibitively expensive as an organization scales its application infrastructure. A licensing model that scales predictably with enterprise growth — rather than penalizing each additional server — is essential for organizations planning infrastructure expansion, as unexpected licensing costs can undermine the business case for a chosen solution.

What technical capabilities should an enterprise APM system provide?

An enterprise APM system should provide real-time visibility into request execution, exception tracking, response time distribution, database query performance, and infrastructure-level metrics. Advanced systems also offer AI-assisted anomaly detection, distributed tracing for microservices architectures, and integration with alerting and incident management platforms.

How does Flopsar address the needs of organizations with large Java application estates?

Flopsar is specifically designed for Java application performance management and addresses the needs of large application estates through its flexible licensing model, low monitoring overhead, and AI-powered Flopsar Index. These characteristics allow it to scale across many servers without the cost penalties associated with per-server licensing models common in competing APM tools.
