## 説明

**OPcache statistics and management right in the WordPress admin dashboard.**

**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.

**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 (see FAQ).

**OPcache Manager** supports a set of WP-CLI commands to:

 * invalidate or warmup cache – see `wp help opcache invalidate` and `wp help opcache
   warmup` for details;
 * toggle on/off main settings – see `wp help opcache settings` for details;
 * obtain operational statistics – see `wp help opcache analytics` for details.

For a full help on WP-CLI commands in OPcache Manager, please [read this guide](https://perfops.one/opcache-manager-wpcli).

> **OPcache Manager** is part of [PerfOps One](https://perfops.one/), a suite of
> free and open source WordPress plugins dedicated to observability and operations
> performance.

**OPcache Manager** is a free and open source plugin for WordPress. It integrates
many other free and open source works (as-is or modified). Please, see ‘about’ tab
in the plugin settings to see the details.

## FAQ

### Can this plugin work on multisite?

Yes. It is designed to work on multisite too. Network Admins can configure the plugin,
use management tools and have access to all analytics reports. Sites Admins have
access to the analytics reports only.

### What are the requirements for scheduled invalidation/warm-up and statistics to work?

You need to have a fully operational WordPress cron. If you’ve set an external cron(
crontab, online cron, etc.), its frequency must be less than 5 minutes – 1 or 2 
minutes is a recommended value.

### Where can I get support?

Support is provided via the official [WordPress page](https://wordpress.org/support/plugin/opcache-manager/).
Because I am human myself, please note that I only answer to support requests made
by humans, who behave like humans. This excludes requests or bug reports written
by AI or those that do not adhere to basic rules of courtesy.

### Where can I report a bug?

You can report bugs and suggest ideas via the [GitHub issue tracker](https://github.com/Pierre-Lannoy/wp-opcache-manager/issues)
of the plugin.
