OPcache statistics and management right in the WordPress admin dashboard.

OPcache Manager

OPcache Manager is a full featured OPcache management and analytics reporting tool. It allows you to monitor and optimize OPcache operations on your WordPress site or network.

See WordPress directory page or official website.

OPcache Manager works on dedicated or shared servers. In shared environments, its use has no influence on other hosted sites than yours. Its main management features are:

• individual script invalidation, forced invalidation and recompilation;
• manual site invalidation - a sort of 'smart' OPcache reset only for your site;
• manual site warm-up - to pre-compile all of you site files;
• optional scheduled site invalidation and/or warm-up.

OPcache Manager is also a full featured analytics reporting tool that analyzes all OPcache operations on your site. It can report:

• KPIs: hit ratio, free memory, cached files, keys saturation, buffer saturation and availability;
• metrics variations;
• metrics distributions;
• OPcache related events.

OPcache Manager supports multisite report delegation.

OPcache Manager is part of PerfOps One, a suite of free and open source WordPress plugins dedicated to observability and operations performance.

The development of The PerfOps One plugins suite is sponsored by Hosterra - Ethical & Sustainable Internet Hosting.

wp-opcache-manager's Issues

Missing argument in the sprintf-function

wp-opcache-manager/includes/system/class-opcache.php

Line 228 in 80e1847

\DecaLog\Engine::eventsLogger( OPCM_SLUG )->warning( sprintf( 'Unable to fully warmup "%s": %s.', $e->getMessage() ), [ 'code' => $e->getCode() ] );

Hi everyone, the 3th argument is required for sprintf
I have got the error during warmup operation:

Fatal error: Uncaught ArgumentCountError: 3 arguments are required, 2 given in /var/www/html/web/wp-content/plugins/opcache-manager/includes/system/class-opcache.php on line 228

PHP version: 8.3.4

OPcache management cannot handle multi-server environments

As described by @JanThiel in a very well documented DecaLog issue (Pierre-Lannoy/wp-decalog#21), OPcache can not be managed like it is for now, in case of clustered PHP environments.
It is therefore necessary to completely rewrite the management and analytics part of the plugin.
