10 Best Python Monitoring Tools

Best Python Monitoring Tools

Diego Asturias

Attempting to pinpoint an application’s performance bottleneck can be like trying to find a needle in a haystack. Looking through different levels of the application stack, from infrastructure to storage, databases, OS, containers, to the end-user experience, can be quite an overwhelming experience.

Python monitoring tools can proactively capture, analyze, trace, and display information related to Python-developed applications. They provide full-stack visibility, which can ultimately help identify and fix Python application performance bottlenecks and improve the user’s experience.

These tools can provide the transparency needed so that developers, operators, and DevOps teams can respond quickly and proactively to issues.

What to look for in a Python Monitoring Tool

Python’s application monitoring tools should be capable of keeping track of vital resources at different levels of the application’s stack, from the infrastructure, platform, to the application itself. Having full-stack visibility helps developers and operations (DevOps) teams identify Python application performance bottlenecks.

Python monitoring tools can usually perform one or all of the following functions.

  • Infrastructure Monitoring. Keep track of application servers, VMs, web services, etc. These tools can collect metrics or logs from these resources, including HTTP requests, response time, or database queries.
  • Application Performance Monitoring (APM). Monitoring and managing the performance at the application level may cover functions like code performance, app dependencies, rendering times, errors, and exceptions.
  • User’s Experience. Keep track of the impact of the application’s performance from the end users' point of view. This is similar to synthetic monitoring, which instead simulates and analyzes the user activity.

Some of the monitoring tools in this list perform one, two, or all previously described capabilities. Additionally, when searching for the right Python monitoring tool, pay attention to features like:

  • Support for Python frameworks such as Django or Flask.
  • Monitoring agents to instrument code and collect data such as error logs or function performance.
  • Application monitoring and optimization through stack tracing.
  • Collection of metrics, traces, logs and errors, and exceptions. Capabilities to correlate some of this data.
  • Create service mappings interdependencies
  • Monitor server resources like CPU, memory utilization, storage (free/consumed), bandwidth, and network latency.

EDITOR'S CHOICE

AppOptics is our top pick for a Python monitoring tool because this service is able to trace all linked applications and microservices, which discovers all of the Python code that contributes to your system even those modules that are hosted elsewhere and provided through APIs. The APM produces an application dependency map and it provides live tracing of execution. With this transaction tracing, you encounter each Python script and can then switch to a code profiler in the AppOptics console, where you can watch each line of code step through as it is executed.

Python monitoring FAQs

How do I monitor a Python application?

It is a lot easier to monitor a Python application if your business created it and hosts it. However, these situations are rare and most users need to trace Python code written and hosted by others. In these instances, you need to get an Application Performance Monitor, which is also known as an Observability tool. Such a system will chain through all of the applications you know about and reveal the external systems that support them – you can’t monitor Python code that you don’t know exists. The Observability platform will then watch your applications as they run through a process called distributed tracing. When it encounters a module that is written in a plain text script, such as Python, it will display that script in a code profiler and track through each line as it runs.

Does AppDynamics support Python?

AppDynamics can track the performance of Python code with its Python Agent. The monitoring package’s team has tested the agent with Tornado, Django, Flask, CherryPy, Bottle, and Pyramid.

What is multithreading Python?

Python is able to implement multithreading, which involves spawning new processes before a running process completes. This means that a Python script can have several processes running on a CPU simultaneously and that speeds up the execution of the module.
