pensivium 0.1.3

The official client library for the Pensieve APM.

pensieve-client 🚀

A lightweight, Django-first APM and error-tracking client for the Pensieve observability platform.

This package is a client library designed to be installed in any Django project. It automatically monitors your application's performance and tracks exceptions.

Its main feature is a fully integrated Django Admin dashboard—it adds a "Performance Insights" page directly to your project's own admin panel, allowing you to see your site's health without ever leaving your workspace.

Features ✨

• 📈 Integrated Admin Dashboard: View error and performance charts directly in your site's /admin/.
• 🐛 Automatic Exception Tracking: Captures and groups unhandled exceptions with full stack traces.
• ⏱️ Performance Monitoring: Tracks request/response times for all your views.
• 📊 Interactive Charts: Provides a "Top 5 Slowest Endpoints" summary and interactive, filterable line charts for drilling down into a specific URL's performance history.
• ⚙️ Lightweight & Configurable: Designed to be low-overhead. Automatically excludes its own dashboard URLs from being monitored.

Installation

1. Install the package using pip:

   pip install pensieve
   

2. Add pensieve_client to your INSTALLED_APPS in settings.py.

   # settings.py
   
   INSTALLED_APPS = [
       # ... other apps
       'django.contrib.admin',
       'django.contrib.auth',
       # ...
       'pensieve_client',
   ]
   

3. Add the Pensieve middleware to your settings.py. It's recommended to place it at the bottom of the list to ensure it correctly wraps your views.

   # settings.py
   
   MIDDLEWARE = [
       'django.middleware.security.SecurityMiddleware',
       'django.contrib.sessions.middleware.SessionMiddleware',
       # ... other middleware
       'pensieve_client.middleware.PensieveMiddleware', # <-- Add this
   ]
   

Configuration

Visit pensieve.harshitajn.tech and register with email, password and name. Create a project and you will get an api key for the project.

Add the following settings to your project's settings.py file:

# settings.py

# Your unique project API key from your Pensieve server dashboard
PENSIEVE_API_KEY = "your-project-api-key-from-pensieve"

# This is the exact url you have to mention in settings.py to get the metrics
PENSIEVE_URL = "[https://pensieve.harshitanjn.tech/api](https://pensieve.harshitajn.tech/api)" 

# (Optional) A list of URL paths to exclude from performance tracking.
# It's a good idea to exclude the admin panel to reduce noise.
PENSIEVEGRID_EXCLUDE_URLS = [
    '/admin/',
    '/__debug__/',
]

How to Use 📊

Once the package is installed and configured:

1. Run your Django project.

2. Log in to your project's admin panel (e.g., http://127.0.0.1:8000/admin/).

3. In the admin homepage, you will see a new section (likely "AUTHENTICATION AND AUTHORIZATION") with a link named "Pensieve Dashboards".

4. Click this link to view your project's performance and error data, which is displayed directly within your own admin.
