Our analysis

AI-assisted

PromPress is a WordPress plugin that tracks various metrics related to website performance and health for integration with Prometheus. It allows you to monitor aspects such as request count, request duration, and user count, providing insights into your site's performance over time.

The plugin requires Object Caching via Redis to store metrics and can be used alongside Grafana for dashboard setup and Prometheus Alertmanager for alerting. This makes it suitable for users who want to keep a close eye on their site's metrics and identify potential issues early.

Best for: This plugin is best for WordPress site administrators who want to monitor site performance and health metrics.

What it does well

  • Tracks a range of website and WordPress specific metrics
  • Integrates with Prometheus for monitoring
  • Supports dashboard setup with Grafana
  • Allows alerting via Prometheus Alertmanager
  • Free to use from the WordPress.org directory

Where it falls short

  • Requires Object Caching via Redis to function
  • Limited to specific WordPress metrics, avoiding general server metrics

Verdict

PromPress provides essential monitoring capabilities for WordPress sites, making it useful for those focused on performance tracking. Its reliance on Redis for caching may limit its use for some users.

From the developer

Peter Booker's own description of PromPress, lightly tidied.

PromPress tracks various website and WordPress related metrics for collection by Prometheus, which allows you to monitor your site’s performance and health. You can even setup dashboards with Grafana and/or setup alerting via Prometheus Alertmanager.

(Note: Requires Object Caching via Redis to be active, so that the plugin can store metrics.)

We track a range of Website and WordPress specific metrics:

  • Request Count
  • Request Duration
  • Request Peak Memory Usage
  • External Request Duration
  • Query Count
  • Query Duration
  • Plugin Updates
  • Theme Updates
  • Emails Sent
  • User Count
  • Post Count
  • Option Count

This gives you the ability to monitor the performance of your website over time and get an early warning of potential problems, like your site sending a lot of emails or the post count increasing a lot.

We purposefully avoid general software and/or server level metrics which are better handled outside of the website, like detailed database metrics which is better handled via the mysqld exporter.
