This plugin provides a simple API for storing miscellaneous log entries and their overview in admin area (or network 
admin area, if activated on a multisite).
Developed for private use (heavily used by my other plugins), but has perspective for more extensive usage. I can’t guarantee any support in the future nor further development, but it is to be expected. Kindly inform me about bugs, if you find any, or propose new features: <a href="mailto:zaantar@zaantar.eu?subject=[wordpress-logging-service]" rel="nofollow ugc">zaantar@zaantar.eu</a>.
See Usage and FAQ for more information.

Automatically detects errors & crashes on your WordPress site using BugSnag to notify you by email, chat or issues system.
All websites crash from time to time, including WordPress sites! Th BugSnag Error Reporting plugin automatically detects crashes, exceptions and other errors in your WordPress PHP code as well as any errors in plugins you are using.
Errors are sent to your <a href="https://bugsnag.com" rel="nofollow ugc">BugSnag Dashboard</a> for you to view and debug, and we’ll also notify you by email, chat, sms or create a ticket in your issue tracking system if you use one. We’ll also show you exactly how many times each error occurred, and how many users were impacted by each crash.

BugSnag Error Monitoring plugin

The plugin is easy to set up; all errors can be monitored via the Bugsnag dashboard. You can also set different log levels and differ between the environments (dev/production) of your website.

Bonus: There are lots of cool integrations like Slack (Push Notifications), GitHub (New Issues) and much more!

Easy error monitoring

Seamless integration with Bugsnag, just perfect.

Works great, people are just dumb

This plugin used to be one of the best tools out there, however, it seems like is not being maintained anymore. 

There is no support for the recent releases of PHP (8.0, 8.1). Recent support requests are not being handled anymore as well.



Abandoned.
