Custom Logging Service

This plugin is derived from the no longer supported
WordPress Logging Service.
Despite that it is not compatiple with it, and there is no upgrade path from one
to the other.

Features

• No log entries generated by the plugin itself, all come from external API calls
• Organisation of log entries in freetext categories
• Severity levels
• Freetext log messages
• Entries can be marked as seen and then filtered from being displayed again
• Filtering by minimum severity level
• Sort by date, category, user name, severity or blog name (in Multisite installations)
• Access to the log page can be granted by user role

API

• string $category

returns true if $category is registered.
