Pressable WooCommerce Fleet Diagnostics

Fleet-wide diagnostic tools for WooCommerce sites on Pressable. Collects site health data, identifies performance issues, and scores sites by optimization priority.

Built on top of Chris Jones's fetch-env-reports.php site health script.

Tools

fleet_probe.php

PHP diagnostic probe that runs on individual sites via wp eval-file. Combines Site Health, WC System Status, and audit-level diagnostics into structured output.

Strictly read-only. Zero writes to customer data.

Collects:

• WordPress/PHP/WooCommerce versions
• Active/inactive plugin inventory with known cache-breaker detection
• Batcache configuration (times, max_age, overrides)
• HPOS status
• Database metrics (table sizes, revision counts, autoload size)
• WP Rocket configuration (preload status)
• WooCommerce settings (AJAX add-to-cart, iAPI Mini Cart readiness)
• Object cache configuration and batch operation support

fleet_collect.py

Python orchestrator that deploys the probe across the fleet via SSH. Reads a CSV site list, handles SSH connections via pressable-connect, deploys the probe via base64 encoding, and captures structured output.

# Test single site
python3 fleet_collect.py --test SITE_NAME

# Test SSH access only
python3 fleet_collect.py --test-ssh SITE_NAME

# Run full fleet collection
python3 fleet_collect.py --run

# Parallel collection (recommended)
python3 fleet_collect.py --run --concurrency 3

# Custom site list
python3 fleet_collect.py --run --csv path/to/list.csv

# Resume from specific site
python3 fleet_collect.py --run --start-from 50

fleet_analyze.py

Analysis engine that parses collected probe output and produces scored reports. Identifies cache breakers, configuration gaps, and optimization opportunities.

# Full analysis
python3 fleet_analyze.py

# Single site deep-dive
python3 fleet_analyze.py --site sitename

# Regenerate report from existing data
python3 fleet_analyze.py --report

Output:

• fleet_data/_analysis.json — machine-readable per-site and aggregate data
• fleet_data/_fleet_report.md — human-readable findings

Requirements

• Python 3.9+
• SSH access to Pressable sites via pressable-connect
• WP-CLI available on target sites
• Site list CSV with a Site Name column

CSV Format

The site list CSV should have at minimum a Site Name column matching the Pressable site identifier:

Site Name,Monthly Uniques
example-site,15000
another-site,50000

Fleet Data

Collection output is stored in fleet_data/ (one .txt file per site). This directory is gitignored as it contains site-specific data.

Known Cache Breakers

The probe detects plugins known to break Batcache caching on Pressable:

Plugin	Severity	Mechanism
facebook-for-woocommerce	CRITICAL	Set-Cookie on every page via wc_setcookie()
pixelyoursite-pro	CRITICAL	session_start() on every frontend page
mailchimp-for-woocommerce	HIGH	Set-Cookie via wc_setcookie()
woocommerce-google-analytics-integration	LOW	Set-Cookie (severity TBD)
yith-ywar-premium-woocommerce-advanced-reviews	HIGH	Set-Cookie via wc_setcookie() on product pages
