Perfino is a powerful JVM monitoring solution that provides you with maximum insights with minimal overhead.

Why choose Perfino?

1. One license can monitor all content: With perfino, you have no limit on the number of JVMs or any other metrics (such as recorded business transactions) that can be monitored.
2. No matter how big your system is or how many microservices you want to monitor, your perfino license can meet your needs.

Check the problem immediately

1. When you log in to Perfino, the dashboard will display whether everything is normal or if there are any issues. Perfino allows you to finely control the acceptable performance level of your application.
2. The dashboard is where you start drilling down to get a more detailed view of the data.

Display calls between virtual machines

1. Perfino can monitor business transactions across multiple virtual machines. Continuing to call the EJB server in the web layer further to the web service - in Perfino, these actions are connected, even if you perform method level sampling.
2. The call diagram not only shows you what is currently happening, but also shows what has happened in the past.

React to nominal external conditions

1. When serious issues arise, you need to take action: create alerts, send emails, or collect more detailed data. In perfino, you can use triggers and actions to configure your emergency response strategy.
2. In the perfino user interface.

Telemetry is everywhere

1. The telemetry data in perfino captures important scalar values in the monitored VM, such as database operations per minute.
2. As mini charts in the dashboard and virtual machine views, they allow you to instantly understand current trends in their full display back to the beginning. Telemetry data will never be discarded, it will only be converted to higher resolution.

Ultra flexible business transactions

1. Perfino automatically detects various business transactions from subsystems such as servlet containers, as well as calls to EJB or RMI. In addition, it also provides multiple methods for you to make any method calls to business transactions.
2. Whether you explicitly choose POJO methods in the perfino UI, tell perfino important comments, or use APIs to create transactions in your own code depends on what works best for you.

Call tree for business transactions

1. The transactions in perfino are organized into an accumulated call tree - as you know from your favorite parser. The level of detail depends on you - it depends on the content you have configured for business transactions.
2. Very slow transactions, etc
3. Policy violations will be displayed separately in the call tree, so you can analyze them separately. Perfino also associates business transactions on the server with page loading times in the browser.

Database performance and bottlenecks

1. JDBC statements and other database operations, as well as queries on MongoDB and other NoSQL databases, are first-class citizens in perfino.
2. When you ask the question 'Which SQL query is the slowest in my application', perfino will provide accumulated backtracking of the answer to the business transaction responsible for the query.

Method level sampling

1. To investigate the internal call structure and method level hotspots of business transactions, perfino performs periodic method level sampling based on each transaction.
2. For slow and very slow transactions, you can configure automatic method level sampling. In many cases, these examples will provide you with an immediate explanation of performance issues unrelated to the database.

Historical Comparison

1. It is very important to be able to compare performance between two time points, especially for agile release management.
2. With perfino, you can review indefinitely to compare selected business transactions or the entire call tree - your data accumulates over time and the time interval increases. The comparison function is directly built into the view used for viewing data.

Cross over to analysis

1. Defense in depth is a strategy applicable to many situations in daily life.
2. When your business is in a critical state, you sometimes need all the tools, which is why perfino can introduce local JVMTI sampling and even prepare a VM for JPProfiler connection. This way, when you need all the features, it is within reach of the analyzer.
