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:
<ul>
<li>individual script invalidation, forced invalidation and recompilation;</li>
<li>manual site invalidation – a sort of ‘smart’ OPcache reset only for your site;</li>
<li>manual site warm-up – to pre-compile all of you site files;</li>
<li>optional scheduled site invalidation and/or warm-up.</li>
</ul>
OPcache Manager is also a full featured analytics reporting tool that analyzes all OPcache operations on your site. It can report:
<ul>
<li>KPIs: hit ratio, free memory, cached files, keys saturation, buffer saturation and availability;</li>
<li>metrics variations;</li>
<li>metrics distributions;</li>
<li>OPcache related events.</li>
</ul>
OPcache Manager supports multisite report delegation (see FAQ).
OPcache Manager supports a set of WP-CLI commands to:
<ul>
<li>invalidate or warmup cache – see <code>wp help opcache invalidate</code> and <code>wp help opcache warmup</code> for details;</li>
<li>toggle on/off main settings – see <code>wp help opcache settings</code> for details;</li>
<li>obtain operational statistics – see <code>wp help opcache analytics</code> for details.</li>
