Installing Blackfire

Installing and updating Blackfire should be a quick process. This document will guide you through the steps.

To start using Blackfire, we are going to install the following:

A language extension;
An agent to communicate with Blackfire's servers (as you chose a quick install, you will use a shared agent instead of installing one on your machine);
A profiling client (a browser extension or a CLI tool).

This installs the APT package for the Blackfire Agent. It might prompt for your password to grant root privileges.

Install pip:

Install the blackfire package:

If you have multiple versions of Python installed on your system, it is possible that you have multiple versions of the pip binary installed as well. For example, you can have pip2 installed for Python >= 2.0, and pip3 installed for Python >= 3.0.
Ensure blackfire-python command is in your $PATH.
Blackfire pip package installs the blackfire-python command, which can be used for zero configuration profiling.

The folder where blackfire-python is installed may vary depending on your Python environment (e.g. pyenv, virtualenv).
Note that the folder blackfire-python is installed in must be in your $PATH.

If you previously installed Blackfire bootstrap configuration hook (blackfire_bootstrap.pth, in versions <= 1.4.5), you must uninstall it by running the following command:

You can now enable monitoring for your environments.

Please refer to the Continuous Profiling Python configuration page for the installation and configuration procedures.

To profile applications, use the Python SDK.

For on-demand profiling, you need to install a profiling client:

Profile from a browser via our browser extensions (Web applications only).

Profile from the command line via the blackfire tool (Web applications, APIs, command line tools, daemons, and more).
